1 Introduction
Various types of vegetable crops are grown in Ethiopia under rain-fed and/or irrigation
systems (ALEMAYEHU et al., 2010). The major economically important vegetables
include hot and sweet peppers (Capsicum spp.), Ethiopian mustard/kale (Brassica
carinata), onion (Allium cepa), tomato (Solanum lycopersicum), chili (C. chinense),
carrot (Daucus carota), garlic (A. sativum) and cabbage (B. oleracea var. capitata).
According to the Ethiopian Investment Agency (2012), green beans (Phaseolus spp.)
and peas (Pisum sativum), okra (Abelmoschus spp.), asparagus (Asparagus officinalis),
cauliflower (B. oleracea var. botrytis), broccoli (B. oleracea var. italica), celery
(Apium graveolens L.), eggplant (S. melongena) and cucumbers (Cucumis sativus)
have also recently emerged as important export vegetables.
In 2013 for example, Ethiopia exported 220,213 tons of vegetables and generated USD
438 million (ETHIOPIAN REVENUE AND CUSTOMS AUTHORITY, 2013). Ethiopia has
favorable climate and edaphic conditions for the production of tropical, sub-tropical
and temperate vegetables in the lowlands (<1500 meters above sea level), midlands
(1500-2200), and highlands (>2200), respectively (FAO, 1984; EHDA, 2011, 2012).
Commercial production of horticultural crops, including vegetables, has also been
increasing in recent years because of expansion of state farms (e.g., Ethiopian
Horticulture Development Corporation) and increasing private investment in the sector
by national and international entrepreneurs (EHDA, 2011, 2012). Commercial
vegetable production is concentrated in the Rift Valley areas of Ethiopia, primarily due
to availability of irrigation facility, accessibility and closeness to agro-processing
industries (ALEMAYEHU et al., 2010). The Ethiopian Horticulture Development Cor-
poration has been carrying out production and marketing activities of horticultural
crops since its establishment in 1980 (AGONAFIR, 1991). The Ethiopian Fruit- and
Vegetables Marketing Enterprise (ETFRUIT) is a parastatal trading organization
established in April 1980 under the Horticulture Development Corporation to deal with
domestic and export trade of fresh fruits, vegetables, flowers, and processed
horticultural products. Relatively, smaller quantities are produced in the highlands,
eastern Ethiopia and some isolated parts of northern Ethiopia. Warm season vegetables
such as tomato, hot pepper and snap beans (Phaseolus spp.) are produced in hot semi-
arid areas both under rain-fed conditions and irrigation (particularly in the Rift Valley),
while the highland offers favorable growing conditions for the production of cool
season vegetables such as Ethiopian mustard, cabbage, potato, garlic, onion, shallot
(A. cepa var. aggregatum), carrot and beetroot (AKLILU, 2000; EHDA, 2011, 2012).
Vegetable production is an important economic activity in Ethiopia, ranging from
smallholder farming to large scale commercial farms (ZELLEKE and GEBREMARIAM,
1991). While smallholders usually use the largest part of their vegetable produce for
Characterization and Assessment of Vegetable Production and Marketing Systems 165

home consumption and sell the surplus, the commercial state and private farms produce
solely for market. According to CSA (2012), about 2,710 million tons of vegetables,
root and tubers were produced on 541,000 ha, creating means of livelihood for more
than 1 million households in 2010/2011. The cultivated crop production area increased
by 26%, while the production volume increased by 73% between 2011 and 2013
(CSA, 2013).
In recent years, awareness of the nutritional and health benefits of vegetables in
Ethiopia has been increasing due to public health advocacy on the role of vegetables in
human nutrition and health through its provision of antioxidants such as vitamin A, C
and E that are important in neutralizing free radicals (oxidants) known to cause cancer,
cataracts, heart disease, hypertension, stroke and diabetes (DEMISSIE et al., 2009;
TABOR and YESUF, 2012) and partly because of the rising prices of livestock products
such as meat, milk and eggs, which traditionally forms a major component of most
Ethiopian diets. As such the increasing consumption of vegetables helps to fight
hidden hunger, malnutrition. Vegetables are also used as a source of raw material for
the local processing industry. Processed products such as tomato paste, tomato juice,
oleoresin and ground spice of hot pepper/chili (Capsicumspp.) are produced for
exports making a significant contribution to the national economy (AKLILU, 2000;
BAREDO, 2013).
Increased national and growing regional demand for vegetables has triggered
commercial production and boosted private investment in the sector by both national
and international entrepreneurs (EHDA, 2011, 2012), increased exports to Djibouti,
Somalia, South Sudan, the Sudan, the Middle East and European markets (TABOR and
YESUF, 2012). This partially affirms government’s policy of increasing productivity of
high value crops with the aim of increasing household income and improving
nutrition. It has been noted that, increasing consumption of vegetables and fruits
contributes to reducing hidden hunger (i.e. micronutrient deficiency), which is related
to health problem caused by a lack of essential vitamins and minerals such as vitamin
A, zinc, iron, and iodine in the diet (ADISH, 2012).
Despite the increasing importance of vegetables in Ethiopia, there is inadequate
knowledge on improved production systems and marketing, especially in the humid
tropics that was the target area of the present study. With increasing population and
declining land size, a better understanding of the production system, marketing
channels and endowed opportunities for growth will go a long way to contribute to
improve return on investment for value chain actors in the sub-sector. Against this
backdrop, the specific objectives of this paper are to: (i) characterize vegetable
production system and assess productivity in the study zones; (ii) analyze the structure,
conduct and performance of vegetables marketing systems in the study area; and

(iii) identify vegetable production and marketing constraints and opportunities and
suggest entry points for future interventions and investment in the sector. The study is
part of the CGIAR research program on integrated systems for the humid tropics, which
aims at reducing poverty, increasing food security, improving nutrition and health and
sustainable management of natural resources. In Ethiopia the study is implemented in
the southwestern highlands, having humid tropics climate (ALEMAYEHU et al., 2010).
2 Methods
2.1 The Study Sites
The study was conducted in three zones and one special district1 which are among the
major vegetable producing baskets in Ethiopia. According to CSA (2012), about 702,
201 smallholder farmers produced 99,368 tons of vegetables on 50,846 ha of land.
West Shewa zone is located in Oromia National Regional State while Gurage and
Hadiya zones and Yem-Special district are located in the Southern Nations,
Nationalities and Peoples Region (SNNPR) (Figure 1). Table 1 shows the list of
districts and kebeles (kebele is the lowest administrative unit in the government
administrative structure) in each of the selected zones. About 90% of the kebeles in the
sample districts grow vegetables. A total of seven kebeles from five districts were
surveyed. The districts and kebeles were selected in a participatory manner through
discussions with zonal and district vegetable experts to ensure that the samples were
fairly representative with respect to the vegetable production potential while addressing
the study objectives.

responsible to zones. Special districts are directly accountable to regional state though they do not
qualify to have zonal status.

Development agents are kebele level extension agents with diploma level qualification
in agriculture, including horticulture. In each of the selected districts, 2 FGDs were
conducted. In each village of the selected district one-women and one men’s-group
participated in separate discussion sessions. In total, 118 farmers (45% female) parti-
cipated in the FGD. The data collected included: type of vegetables produced, ranking
of vegetables in order of importance, area under production, nature of production
system, volumes produced, types and sources of inputs, purpose of production, amount
of vegetables marketed, mapping of vegetable value chains and actors, marketing
channels and costs, sales prices, and constraints and opportunities in the value chain.
The data collected were coded and entered into Excel spreadsheets and SPSS Version
20 statistical software package. Data obtained from various sources were also triangu-
lated, checked for consistency and analyzed. Descriptive statistics were used to
analyze and present the data.
3 Results and Discussion
3.1 Vegetable Farming System and Variety Preference
In the study local, vegetable production is integrated into mixed farming system where
different types of crops are produced on the same plot of land or in sequence with
other crops in rotation. Depending on availability of land and crop suitability for
intercropping, some vegetables are grown either as sole or intercropped with other
vegetables or cereals. Vegetables such as tomato, beetroot, Swiss-chard, lettuce, carrot,
cabbage, onion, garlic, kale, sweet potato and hot pepper are dominantly grown as sole
crop whereas Ethiopian mustard and pumpkin are dominantly intercropped with maize
and other annual or perennial crops, and with Irish potato especially in homesteads.
Integrating vegetable production in a farming system has contributes substancially to
food and nutrition security as the vegetables complement stable foods for a balanced
diet by providing vitamins and minerals. Due to such benefits, some projects such as
“better potato for better life” project are supported by USAID and implemented by the
International Potato Center (CIP) in Ethiopia.
Vegetables are usually grown in two seasons, namely in the wet season (locally known
as meher season) using rainfall with supplemental irrigation or under full irrigation
during the dry season. Vegetables such as pumpkin, Ethiopian mustard, hot pepper,
sweet potato, and some others are predominantly grown under rain-fed conditions.
Irrigated farming is considered costly due to the intensive use and high cost of diesel
fuel for pumping water, agro-chemicals and hired labour costs. Thus, choice of crop
selected for irrigation is critical. Results from the focus group discussions indicate that
green beans, Irish potato, kale, cabbage, tomato and onion have high market value to
Characterization and Assessment of Vegetable Production and Marketing Systems 169

offset high cost of production under irrigated farming systems. Irrigated farming also
enables the farmers to align harvest time to meet off-season higher market demand,
when farm-gate prices are much higher. During the rainy season, farmers follow a
similar strategy by ensuring that the timing of planting and harvesting coincides with
periods of higher consumer demand and competitive farm-gate prices, thereby avoiding
periods of peak market gluts. In Ethiopia vegetable consumption often increases
during the Christian fasting period, when livestock products are not consumed and the
demand for pulses and vegetables are high. Vegetable growers often align their plant-
ing time so that harvesting will coincide with the fasting period. Producing under
irrigation also enables the farmers schedule production pattern to avoid periods of high
pest and disease infestation.
Depending on the agro-ecology and resource availability, the type of vegetables grown
in the different districts of Ethiopia varies. The results of the study are thus consistent
with the findings of other authors (see for example, HAJI, 2007) and confirm that there
is both vegetable integration as well as diversification in the study districts. Certain
vegetable types are dominant in specific districts. To this end, results from the
subjective ranking assessment of the dominance of vegetable types by respondents
from the various farm households and expert opinions were consistent. In terms of
geographic distribution, tomato, onion, cabbage and Irish potato are among the top
ranking vegetables while kale is dominant in Gurage and Hadiya zones in general, and
in Meskan and Anlemo districts in particular (Table 2).

A preference assessment for varieties indicated that, there is preference for specific
varieties due to differences in key identified attributes. The major attributes for tomato
include low perishability, high yield, taste and ability to attract a premium price.
Although head size and head compactness are important attributes in selecting cabbage
varieties, availability of seed is the overall governing factor for preferring a variety
such as ‘Copenhagen’ as the sole variety for production in some areas. Fast growth
and tolerance to diseases are important attributes for preferring different local varieties
of Ethiopian mustard. However, in most cases availability of seed dictates the type of
varieties selected for production. Color, early maturity and market demand are the key
attributes of best onion varieties. Availability of planting materials and clove size
govern selection of garlic cultivars, which is quite logical in the sense that there are no
formal sources of garlic planting materials in Ethiopia. Yield, color, pod size and
market demand are on the other hand the most important criteria in selecting hot
pepper varieties. Notwithstanding the role of the specific attributes determining varietal
selection, availability of seed/planting materials dictates what type of vegetable variety
to grow in most cases, implying the critical shortage of improved seed and/or planting
material supply at required time and space.
3.2 Production Area and Yield Estimates of Vegetables
According to CSA, the area under all vegetables grown by smallholder farmers in-
creased from 351,000 ha in 2010 to about 397,000 ha in 2013 in Ethiopia, representing
an increase of about 16%. Total production also increased by 87.5%, from about
2.4 million tons in 2010 to about 4.5 million tons in 2013 (Figure 2). The aggregated
average yield of all vegetables is used as the indicative aggregate productivity of all
vegetables, though the yield of individual crops are notably very different. The result
showed a staggering trend between 2010 and 2012, increasing from 6.7 tons/ha in
2010 to 7.6 tons/ha in 2011 and then declined to 6.4 tons/ha in 2012 and finally
increased to 11.3 tons/ha in 2013. For non-root type vegetables, the average yield over
the four year period were 4.0 ton/ha in 2010, 5.3 ton/ha in 2011, 4.7 ton/ha in 2012 and
4.4 ton/ha in 2013, showing a relatively stagnant and low yield trend over the periods.
According to the survey results, the total area allocated for vegetable production for all
4 study zones during the 2012 production year was 85,827 ha. The largest area was
allocated to vegetables to the West Shewa Zone followed by Gurage Zone (Table 3).
On average, about 35% of the total area under vegetable production in the zones is
irrigated. The proportion of irrigated vegetable land ranged from 23% in Gurage Zone
to 55% in Yem-Special District.

Table 4 shows the land allocated to different vegetables in the study zones under rain-
fed and irrigated production systems for the 2012 production season. In West Shewa
Zone, vegetables such as potato, onion, cabbage, Ethiopian mustard and garlic are
dominant vegetables produced under rain-fed conditions, occupying 72% of the total
area of vegetable production. In Gurage Zone, Irish potato alone accounted for 78% of
vegetables grown under rain-fed conditions. Irish potato and sweet potato occupied the
largest share (77%) of area allocated for rain-fed vegetable production in Yem special
district. In Hadiya zone, cabbage, beetroot and carrot together accounted for 69% of
the total area allocated for rain-fed vegetable production. In West Shewa Zone, the
largest area (74%) of irrigated vegetable land was allocated for potato, onion and
tomato production. In Gurage Zone, the largest area of irrigated vegetable land was

covering 79% of the total area allocated for all vegetables under irrigation. In Hadiya
zone, tomato, cabbage and onion together shared 64% of the total land allocated for
vegetables production under irrigation. In all the four zones, cassava (root is consumed
as a side dish similar to potato) and pumpkin were not grown under irrigation, as
revenues accrued from their sales are insufficient to offset the high investment cost for
irrigation.

Out of the 46 districts in the study zones (20 in West Shewa, 1 in Yem-Special District,
15 in Gurage and 10 in Hadiya), the five studied districts account for about 19% of the
total vegetable areas of which 31% is under irrigation. This shows that the study
districts are potential areas for vegetable production within the humid tropics of
Ethiopia. More importantly, over one-fifth of the most important vegetables such as

tomato, cabbage, Ethiopian mustard, hot pepper, beetroots and Swiss-chard largely
produced for market are supplied from the study districts (Table 4).
Analysis of FGDs indicates that almost all farmers in all the study districts are engaged
in the production of major vegetables of economic importance. The area allocated by
households for the production of these crops varies and is often very small. The
average household level area allocated for vegetable production in the five districts
ranges from 0.11 ha in Meskan to 0.19 ha in Ambo. For example, in Toke Kutaye
district, an average of 0.38 ha of land was allocated for tomato production per house-
hold, which is much higher than the area allocated to other vegetables. Similarly, only
a very small land size is allocated for production of beetroot as well as hot pepper. In
Ambo district, onion production is most common, occupying an average of 0.5 ha of
land per household whereas only 0.25 ha was allocated for each of tomato, cabbage
and garlic.
According to information obtained from the Zonal Agriculture Offices of the study
locale, about 1.28 million tons of vegetable crops were produced during the 2012
production year, representing about 50% of the national data reported by CSA for the
same year. The zonal/district office’s data on production was extrapolated based on
data from yield estimates obtained from the respective zones and area under
production. The data indicates that about 0.5 million tons (39%) of vegetable
production was under irrigated farming (Table 5). For the study zones as a whole,
about 25% of the irrigated vegetable produce comes from the study districts. The
major share of vegetable production (70%) in the study districts is produced under
irrigated conditions. However, there is variation among the zones and districts in terms
of irrigation potential and use. The total production in Gurage zone was 102.6, 13.4
and 12 times higher than the amount produced in Yem-Special District, Hadiya and
West Shewa Zones, respectively. In West Shewa Zone, vegetables such as potato,
onion, Ethiopian mustard, cabbage and beetroot together make the largest share (85%)
of the total vegetables under the rain-fed system whereas the amount of Swiss-chard,
carrot and lettuce is only 1% of the total production.
Irish potato is the most important vegetable produced in all of the zones. Ethiopian
mustard/kale is the second most important vegetable produced in Gurage zone. The
result reflect crop adoption patterns that are based on relative comparative advantage
of the different vegetables in the various agro-climatic zones as well as the production
and food consumption habits of the associated populace at each location.

The yields under rain-fed and irrigated conditions of the most common vegetables
were estimated (Table 6) by the farming communities involved in the focus group
discussions. The yield depends on the production season and the vegetable type. For
example, onion, garlic, hot pepper, beetroot, carrot, sweet potato and potato registered
higher yields under irrigation production compared to rain-fed production. On the
other hand, tomato, Swiss chard and lettuce registered lower yield under irrigation than
under rain-fed in similar farming system. According to the respondent farmers, the
divergent results could be attributed to the differences in susceptibility to diseases
during the rainy season and to insect pests and heat during the dry season. The average
yield of the vegetables in the study districts is more skewed to the right as compared to
average yields reported by the district offices. This could be attributed to either the
relatively good potential of the study kebeles or perhaps estimation bias by horti-
cultural experts at the district level.

Generally, the average productivity of all crops was by far lower than the yield
potential of the crops recorded by research centers in research stations and on-farm
demonstration plots using improved management practice (Figure 3). The low
productivity on farmers field and on-farm demonstrations plot can be attributed to low
use of inputs such as fertilizer and crop protection chemicals as well, inadequate
cultural management practices such as weed control and knowledge gap in production
and management techniques. For instance, tomato yields can be as high as 40 tons/ha
in research stations, 25 tons/ha at on-farm demonstration plots, while the national
average yield is about 9 tons/ha (TEKLEWOLD and MEKONNEN, 2012). For vegetable
crops such as tomato, onion, carrot, beetroot, Swiss chard and lettuce, the lower
productivity cannot be ascribed to the use of low yielding cultivars per say since in all
cases seeds of improved varieties are used by the farmers. However, these cultivated
varieties are highly susceptible to diseases and insect pest infestation, moisture stress,
lack/suboptimal uses of inputs such as fertilizers and chemicals as reported by farmers.

As shown in Table 8, more than 65% of all major vegetables produced during the 2012
production year were sold on the market. The responses from interviewees were
consistent and conclusive. This implies that vegetables provide substantial cash
income generating opportunity for the farming community to access food (i.e., by
selling marketed surplus and buying other food from the market) for enhanced lively-
hoods.
Not surprisingly, most households producing vegetables for the market also consume a
portion at home. However, only vegetables preferred as part of the regular diet are
produced mainly for consumption by the household. As shown in (Table 7), kale,
pumpkin and Ethiopian mustard are largely produced for consumption. Sweet potato
(tuber is mostly consumed as a side dish) is considered as food security crop during
periods of drought due to its drought-tolerance characteristics. In the study sites, sweet
potato is considered predominantly as a key crop for resource poor farmers. Although,
most vegetables are also grown by resource poor farmers, the scale of production is
low and the purpose is largely for home consumption. The major reason for this ob-
servation is the lack of adequate capital to access inputs such as vegetable seeds, land,

irrigation facilities, as well as agro-chemicals; the prices of which are unaffordable to
these farmers. Analysis of the survey data indicated that the rich and medium wealthy
household groups2 produce a variety of vegetables largely for sale while a portion is
also consumed at home. Vegetables are consumed more by the relatively higher income
group and better educated consumers, mostly in urban cities than resource poor and
uneducated farmers. Except for garlic and potato which are produced only by rich and
medium class farmers due to the high cost of planting materials, all other vegetables
were produced by all income classes.

During the survey, it was observed that horticulture experts were mostly aware of the
nutritional importance and quantities of various vitamins and other nutrients of the top
five vegetables produced in their area. However, specific nutritional values of vegetables
are not well known to farmers. Moreover, most of the development agents who are
supposed to promote the adoption of improved vegetables production practices do not
know the specific nutritional value of the crops. Only 33% of the respondent develop-
ment agents indicated that crops such as tomato, cabbage, and kale serve as important
2 Wealth group was determined in relative terms as perceived by the respondents.

sources of vitamins, 8% indicated that onion, hot pepper and carrot are rich sources of
vitamins. On the other hand, 8-25% of the development agents respondents do not
have a fair knowledge of the nutritional values of most vegetables. About 33% of the
development agents indicated that potato is an important source of carbohydrate. This
reveals a knowledge gap to persuade farmers to produce vegetables which is part of
the extension packages outlined by the official agricultural extension program in the
country.
In addition to their economic and nutritional importance, vegetables also possess social
and medicinal values. Consequently, development agents and farmers (through FGD)
were asked whether they were aware of the social value and medicinal values of
vegetable crops commonly produced in their area. About 42-50% of development
agents responded that vegetables such as tomato, cabbage, kale, onion and potato are
usually offered as gifts to relatives or neighbors as a means of social support. This
occurs mainly when the relatives or neighbors do not have own access to such
vegetables. About 25% and 8.3% of the respondents stated that kale and cabbage play
key roles in preventing constipation, respectively. Another 8.3% of the respondents
also stated that onion, garlic and sweet pepper have medicinal value although they do
not know exactly what it is. Carrot has medicinal value for 25% of the respondents
while garlic is considered as medicine for preventing various diseases such as common
cold.
Production Constraints
Despite the immense merits of vegetables to farmers, their production has been
constrained by a myriad of biotic (i. e., diseases, insect pests and weeds) and abiotic
factors (i.e., soil acidity and low soil fertility) as well as institutional (e.g. policy,
market, and infrastructure). The constraints could thus be categorized under 3 factors
viz: (i) natural factors, (ii) institutional and policy factors, (iii) market factors.
The natural production constraints identified include the perishable nature of vegetables,
pests and diseases infestation, and extreme moisture levels (i.e., high during rainy
season, and shortage during the dry season). The results from the key informants and
FGDs stress the critical importance of postharvest losses which occur due to the
perishable nature of vegetables and lack of appropriate postharvest handling practices
and processing technologies. The high incidence of insect pest and diseases infestation
further accentuates high pre-harvest and postharvest losses. In adequate or erratic
rainfall or lack of irrigation water was also found to result in low moisture stress,
causing yield reduction. As indicated in Table 9, tomato was among the most signifi-
cantly affected crops by diseases (97%), postharvest loss (82%) and low moisture
stress (68%) as the pooled data from all respondent categories. Cabbage and onion
180 B. Emana, V. Afari-Sefa, F.F. Dinssa, A. Ayana, T. Balemi and M. Temesgen

come after tomato in terms of susceptibility to low moisture stress (55%) and
postharvest loss (44%). Late blight caused by Phytophthora infestans and bacterial
wilt caused Ralstonia solanacearum were reported as the important diseases that affect
potato and tomato in the study areas. There was no reported disease affecting Ethiopian
mustard production in the study area, although aphids were reported to cause heavy
damage. Only 8% of the experts interviewed mentioned carrot to have been suffering
from diseases and pests. Powdery mildew was among the most important diseases of
carrot. Garlic, beetroot, carrot and Ethiopian mustard were among the crops having no
specific reported problems of postharvest losses, as far as transportation distance is not
too long.
The major institutional constraints affecting vegetable production relates to the lack of
access to improved and pest and disease resistant vegetable varieties, especially for
potato, sweet potato, hot pepper and tomato and lack of a functional vegetable seed
certification/regulatory system, ultimately resulting in the use of uncertified poor
quality seeds by farmers. This partly as a result of the lack of private seed companies
involvement in the vegetable seed supply and distribution channel. Almost all vegetable
seeds are imported with their quality and sources hardly known. This has an impact on
the overall production and lack of institutionally coordinated (e.g., as through coopera-
tives/union, MoA) seed supply system in some districts such as Guder and Ambo in
the study areas. Other factors include the fragmented nature of vegetable farms creating
inconvenience for coordinated market linkages and lack of policy initiatives to address
the issue. Despite the fact that government planned to develop small scale irrigation,
which is often used for vegetable production, there is inadequate irrigation water in
some districts (Guder, Ambo, Yem), resulting in conflict among farmers associated
with periodic rationing of irrigation water use.
Vegetables are also sold at local markets in villages and district capitals. Lack of a
reliable market in all the zones appears to be another critical bottleneck of vegetable
farming. Discussions particularly with producers and traders revealed that the existing
market infrastructure and poor transport and warehouse facilities do not suit the
perishable nature of vegetables as a result of which the quality of vegetables such as
tomato and onion deteriorates. During the peak vegetable production season, farmers
are forced to sell the products at extremely low prices particularly for tomato, and
onion (because of lack of appropriate storage structure to avoid sprouting) thereby
discouraging farmers from producing in the immediate subsequent season. Producers
and local traders lack reliable market information and support systems. Brokers and
wholesalers in the terminal market determine prices and even sometimes refuse buying
harvested produce. Due to the perishable nature of vegetables, producers are forced to
become price takers and accept low prices offered by brokers and wholesalers and
even in some cases abandon their produce in market. The largest proportion of respond-

ents indicated that tomato suffers from lack of market access and/or poor prices
received (82%). Similarly, cabbage (53%) and onion (50%) are also largely affected
by marketing related problems (Table 9).

Vegetable value chains and marketing functions
The functions involved along the value chains of various vegetables in the districts are
more or less similar. Differences appear mainly in the channels produce pass through
in the trading functions and actors assuming different roles. Thus, mapping of value
chain functions mainly shows the relationships and integration of the processes and
activities performed along the value chain. Major value chain functions include: input
supply, production, trading, processing and consumption. Figure 4 displays the func-
tions or processes in vegetables value chain, the activities performed under each of the
functions and the actors among the different value chains.

Characterization and Assessment of Vegetable Production and Marketing Systems 183
Quarterly Journal of International Agriculture 54 (2015), No. 2; DLG-Verlag Frankfurt/M.
Marketing functions are mostly carried out by producers, retailers and whole sellers
from outside the study areas. For commodities produced within the study areas, how-
ever, all marketing activities are handled either by retail shops mixing vegetables with
fruits or farmers who sell the products in open markets. At Anlemo and Yem-Special
districts there are no retailers in the value chain performing standard marketing
functions. Wholesaler participation is only for limited commodities (onion, potato and
garlic). In both Ambo and Butajira towns there are also retailers selling vegetables to
urban consumers. Processing of vegetables, in the sense of preserving and value addi-
tion, is not practiced as such in the study areas. Processing is undertaken mainly by
hotels or restaurants in which case fresh and cooked vegetables are sold to consumers.
In major towns of the study areas, very few individuals process potato into chips and
sell by the roadside.
The consumer base includes urban, per-urban and rural dwellers, who buy and con-
sume a wide range of vegetables. Village market consumers and farmers themselves
absorb a substantial volume of the produces. In terms of consumers groups, FGD
participants in Anlemo district were of the opinion that vegetables are mainly pro-
duced for urban consumers with little for their communities.
Marketing Channels
Producers sell vegetables through different channels. The shortest channel is direct
sales to consumers as shown in Figure 5 (Channel 4). Producers also sell to local
collectors or wholesalers or retailers. At Yem and Anlemo districts, the marketing
channels were found to be much shorter with produce sold mainly at village markets or
district markets. Retailers are not typically involved in marketing related activities in
these districts. In Meskan district, produce are sent to urban centres and sold in open
markets although few retailers operate. In this case, producers sell the produce to
consumers and retailers as well as to wholesalers based in markets outside the district.
There are approximately 12 vegetable traders at Buta Jira, the capital of Meskan
district. These traders transport the product to other markets including Addis Ababa at
peak supply periods. At Ambo district, about four wholesalers take part in vegetable
marketing serving as major providers to retail shops and hotels in the town.

Marketing Constraints
The major marketing constraints include high postharvest losses, poor marketing and
value chain development, and weak linkages and integration among value chain actors.
Postharvest losses of vegetables are high primarily because of poor postharvest
handling, poor storage infrastructure and transportation facilities as well as poor
market information and support systems in rural areas. Smallholders in rural areas are
often poorly linked to markets and do not adequately access functional market
information. Often middlemen do make much higher marketing margins than the
producers, limiting the motivation of farmers to expand vegetable production, not
forgetting the associated high input costs such as fertilizers and agrochemicals.
Vegetable value chains are also generally poorly developed. Although there are many
public, private, NGOs and development partners working across the entire vegetable
value chain, including seed systems, there are weak linkages and integration among
the chain actors. As a result, there are no consistent and complementary synergistic
efforts to develop the horticultural sector of Ethiopia (DCG, 2007).
4 Conclusions and Recommendations
Vegetables are an integral part of the farming system, which plays a crucial role in the
economy of Ethiopia. Vegetable production is increasing as a result of increased area

allocation as well as increased yield per unit area as well as area put under production.
Much of the increase in production comes from area expansion and increase in small-
scale irrigation activities, enabling two or more production cycles per year. However,
productivity at smallholders' level is very low compared to yields obtained at research
centers. Production is constrained by diverse abiotic and biotic factors. Lack or limited
access to improved seeds, diseases and insect pests, high postharvest losses and poor
marketing system are the major challenges of the sub-sector with tomato suffering the
most from these challenges. Vegetable marketing is also constrained by lack of market
information systems, poor market linkages, low institutional support, lack of value
chain development to ensure participation and benefit to the smallholders. This neces-
sitates looking into the whole vegetable system development via a value chain
upgrading/development approach.
Based on the findings of the study, the following recommendations are proffered:
i. Improve the technical knowledge and skill of farmers and development agents
in vegetable production and crop protection measures by providing training in
improved production and crop husbandry practices and use of quality inputs so
has to provide effective extension service to increase vegetable yield.
ii. Expand irrigation facilities and improve cost efficiency of irrigation water use
by improving the irrigation system for example by shifting from flood and
furrow irrigation to drip and sprinkler irrigation methods.
iii. Increase public and private sector investment in irrigated vegetable production
to increase the supply of vegetables since analysis of data from commercial
farms revealed higher yield of vegetables compared to smallholder farms due to
increased use improved inputs, particularly irrigation.
iv. Strength research-farmer-extension linkages to develop improved varieties
adapted to diverse biotic and a biotic stresses, and improved management prac-
tices so as to overcome the current production pitfalls to address the wider
observed yield gaps.
v. Develop improved and affordable postharvest handling and storage structures to
prolong shelf life and minimize postharvest losses.
vi. Build the capacity of farmer’s cooperatives/unions so as to provide cooperatives
with much better opportunities for integrating smallholders into vegetable value
chains so that the profit margins of the farmers could be improve.
vii. Engage government and policy makers in frequent dialogues to increase their
awareness so as to enhance widespread implementation of vegetable seed certi-
fication policy/regulations to support vegetable value chain development so that
farmers get sustainable incentive to increase production.

Given the recent expansions in the country's small-and medium-scale irrigation scheme establishment, vegetables are excellent crops for agricultural system diversification and land intensification. The country's climate is ideally suited for the development of seeds for a variety of crops, ranging from temperate to tropical vegetables (Emana et al., 2015;Shimeles, 2000). ...
... Depending on availability of land and crop suitability for intercropping, some vegetables are grown either as sole or intercropped with other vegetables or cereals. Vegetables such as tomato, beetroot, Swiss-chard, lettuce, carrot, cabbage, onion, garlic, kale, sweet potato and hot pepper are dominantly grown as sole crop whereas Ethiopian mustard and pumpkin are dominantly intercropped with maize and other annual or perennial crops, and with Irish potato especially in homesteads (Emana, 2015). ...

The production of vegetables is very important to Ethiopia's economy and various types of vegetables can grow in Ethiopia. However, despite the existing potentials, smallholder vegetable farms are based on low input–low output production system in the country. The production is run by smallholder farmers and is located on a relatively small part of land. In the same way, there is inadequate knowledge on improved vegetables production practices, challenges and opportunities by smallholder farmers in the country and public research on vegetable crops was negligible. To this end, this review was aimed to assess practices of vegetable production and management, challenges of vegetable production and management and opportunity of vegetable production by small holder farming household. The review found that, vegetable production practices and management are not the primary activity for the majority of smallholder farming households in the country; rather, they are seen as a supplement to the production of major crops. It was mainly based on traditional farming system. Further the review found out that, lack of access to credit, limited supply of improved seed, marketing and market information, appropriate management techniques, appropriate disease and insect pest control measures, outbreak of new disease and pest are among the main challenges of vegetable production in the country. This is mainly because of the limited resource allocation to research and development including the extension services. Finally, the review recommends that, in promoting vegetable producer households, diversified and intensified agricultural farming, and problems related to extension service and research, credit service, disease and pest control, market and marketing information, and provision of modern agricultural inputs should be addressed by concerned bodies.

... Selling price volatility and a scarcity of market access are almost always cited as major constraints to irrigated agriculture in Ethiopia (Kassie 2020). In many cases, middlemen earn much higher marketing margins than the farmers, which reduces the farmers' incentives to increase their production (Emana et al. 2015). ...

This study evaluated the on‐farm performance of two small‐scale irrigation schemes, Furfuro and Bedene Alemtena (hereafter referred to as Bedene), in the Ethiopian Rift Valley. Two sets of performance indicator parameters were used. The first group was internal performance indicators, which included conveyance, water application and application uniformity. The water flow velocity through canals was monitored using the floating method. The amount of irrigation water applied to the fields was measured using a cutthroat flume. The second group was external performance indicators, including agricultural performance, water use performance and physical sustainability indicators. The results indicated that Furfuro had average conveyance, application and uniformity efficiencies of 84%, 59% and 50%, respectively, while that of Bedene were 79%, 63% and 55%, respectively. The overall efficiencies for both schemes were about 49%, which is lower than the minimum permissible values. The outputs per irrigation supply and consumed water for Furfuro were 0.14 and 0.16 US$/m ³ , respectively, and they were 0.11 US$/m ³ for Bedene. The relative irrigation and total water supply of Furfuro were 1.21 and 1.20, respectively, indicating the presence of excess water in the command area during the study season. The relative irrigation and water supply of Bedene was 0.81, which indicated that the scheme was water deficient. Irrigation water management practices need improvement in the two schemes.
... Increasing crop yields is significantly aided by appropriate crop management. The primary causes of the low productivity in vegetable production are the lack of technical knowledge and skill among farmers and development agents [2]. The environment and crop variety may influence the optimal level of agronomic practices like plant population density and fertilizer rate [3]. ...

A field experiment was carried out during the two successive winter seasons of 2020-2021 and 2021-2022, in the private vegetable farm at Diarb Negm District, Sharkia Governorate, Egypt, to study the effect of mineral nitrogen levels and plant density on fresh weight, total N, P, and K uptake, total yield, nitrogen use efficiency, and bulb quality of the onion (cv. Ahmar tantawy). This experiment included 12 treatments, which were combinations between four levels of mineral nitrogen (0, 192, 240, and 288 kg N/ha) and three plant densities (4, 5, and 6 rows per ridge, equalling 33.33, 41.67, and 50 plants per m2, respectively). These treatments were arranged in a split-plot design with three replications. Nitrogen levels were randomly arranged in the main plots, and plant densities were randomly distributed in the subplots. The interaction between nitrogen levels at 288 kg N/ ha and plant density (4 rows/ridge) gave the highest values of fresh weight of leaves, bulbs, and total fresh weight/plant, percentages of the yield of grade 1, grade 2, and exportable yield from total yield, and increased total N, P, and K uptake by the plant, total carbohydrates, total sugars, and vitamin C contents in bulbs. The interaction between N at 244 kg/ha and high plant density (6 rows/ridge) increased total yield per hectare and nitrogen use efficiency in onion plants.

Local irrigation institutions are crucial for effectively managing and sustaining irrigation schemes. This study assessed the farmers' perceptions on technical and irrigation water user associations' (IWUAs) management performance of selected irrigation schemes in the Ethiopian Rift Valley. Four small-scale irrigation (SSI) schemes, namely, Furfuro, Murtute, Bedene Alemtena (hereafter referred to as Bedene), and Sibisto, were selected for this study. Data were collected using scheme performance reports, household surveys, key informant interviews (KII), focus group discussions (FGD) with various stakeholders, and field observations. Results showed that the reliability and water delivery performance of Furfuro and Sibisto were rated as good by 52% and 41% of respondents, respectively, and poor by 22% and 25%. In Murtute and Bedene, 73% and 51% of respondents, respectively, said that the reliability and water delivery performance were poor, and 11% and 21% rated them as good. Similarly, in Murtute and Bedene, 32% and 37% of respondents, respectively, said that the water allocation was seriously unfair, and 50% and 43% said that they occasionally see unfairness. Although the severity of the problems varies between schemes, the operation, maintenance, and water allocation systems of all schemes were unsatisfactory. The general observation of participants in FGD, KII, and household surveys indicated that the IWUAs were unable to manage the schemes based on the outlined rules and regulations. Lack of training and financial constraints affected the IWUA's ability to manage the schemes properly. In general, poor market access, high input costs, and inefficient irrigation management systems impacted the irrigation production in the study area.
... Literature reviews results showed that many scholars (Abduali et al., 2017;Adugna, 2021;Aliyi et al., 2021;Asale et al., 2016;Banchamlak & Akalu, 2022;Eticha, 2017;Emana et al., 2015;Mahmood et al., 2017;Mdoda et al., 2022;Mukaila et al., 2021;Negasi, 2016;Olowo et al., 2022;Onuwa et al., 2021;Rehima, 2006;Wongnaa et al., 2019) have conducted studies on vegetables in Ethiopia and different countries of the world. However, the majority of these studies focused on identifying marketing channels for individual vegetables and provided limited empirical data on production profitability and marketing systems for vegetables. ...

This study analyzed vegetable production status and marketing systems in Ethiopia, Sebeta Hawas Woreda, and the Oromia region. The study collected primary data through household surveys, focus group discussions, observations, and key informant interviews. The data were analyzed using descriptive statistics, the gross profit formula, and the structure-conduct-performance model. The study results revealed that cabbage, onion, and tomato were the top three vegetable crops dominantly grown, contributing 67.7% of the total vegetables produced in the study area. The profitability analysis results indicated that tomato, onion, and cabbage production was profitable. The results of the market structure analysis indicated that the market structure for onions, tomatoes, and cabbage was a strong oligopolistic market. The market conduct analysis result revealed that the prices of vegetables were determined by the traders. The results of market performance analysis revealed that the dominant marketing channel for onions, tomatoes, and cabbage was the “producer → broker → wholesaler → retailer → consumer” channel. Smallholder farmers obtained the highest profit shares of 61%, 39%, and 51% from cabbage, onion, and tomato, respectively, when vegetables were directly supplied to wholesalers. The study results revealed that vegetable production was profitable, though the marketing system was found to be inefficient. Therefore, the study suggested intervention by the government through the design of effective policies to improve the performance of vegetable production and marketing systems. Furthermore, NGOs can provide tailored training, and universities, research institutes, agrochemicals, and seed companies can supply cost-effective agricultural inputs so that vegetable production and marketing systems are enhanced.
... As crops are high-value in nature, it is normal to increase the commercial cultivation of vegetables [8]. Vegetables assist in preventing cancer, heart disease, cataracts, hypertension, stroke, and diabetes by providing antioxidants such as vitamin A, C, and E [9][10][11]. Bangladesh is blessed with weather and soils that are conducive to growing a wide range of vegetables. Moreover, in the cultivation of vegetables, Bangladesh has a comparative advantage which has resulted in potential opportunities for the sector [12]. ...

... Ethiopia has a high capability, favourable climate and edaphic conditions (EHDA, 2012;Emana et al., 2015) for vegetable production because of various factors suitable to growing these crops, including topography, climate, and soil (Hunde and Nimona, 2017). Recently, vegetable production has been considered as an essential economic activity in Ethiopia that ranges from gardening smallholder farming to commercial farms and private enterprise (Rahiel and Gebresilasie, 2018). ...

Agriculture is still the leading sector in economic development of Ethiopia. Recently, farmers' adoption of sustainable intensification practices considered as the best strategy to ensure economic and environmental sustainability concomitantly. The aim of this study was to identify determinants of adoption of sustainable intensification practices in eastern part of Oromia region, Ethiopia. Using multistage sampling technique, 383 households was drawn from the study population. The study used multivariate probit model to analyse factors influencing adoption of sustainable intensification practices. The result of the model revealed that factors like Extension service, Education, Farm size, Livestock and access to training significantly an positively enhance adoption of sustainable intensification practices while access to media negatively influence adoption of sustainable intensification practices. The results of the study also indicate that there is complementarity between crop rotation and conservation tillage and a negative correlation between organic fertilizer and conservation tillage. From the result we can conclude that adoption of sustainable intensification practices are complementary and can jointly better enhance soil and environmental conservation.

Onion is one of the important vegetable crops produced in many home gardens and in some extent commercially in different parts of Ethiopia. Therefore, this experiment was conducted at Alage Central Rift Valley of Ethiopia with the objectives of assessing the growth, yield, and quality response of onion to the variable rates of poultry manure and mineral nitrogen fertilizer. The experiment comprising of three nitrogen levels (0, 46, and 92 kg ha<sup>-1</sup>) and four levels of poultry manure (0, 5, 10, and 15 t ha<sup>-1</sup>) were laid out in a randomized complete block design with three replications. The result indicated that leaf length, leaf number, days to maturity, bulb length, and bulb dry matter content were significantly influenced by main factors. Application of poultry manure at the rate of 15 t ha<sup>-1</sup> recorded the highest total bulb yield (63.33 t ha<sup>-1</sup>) and marketable bulb yield (62.52 t ha<sup>-1</sup>), but statistically, there was no significant difference between 15t ha<sup>-1</sup> and 10t ha<sup>-1</sup> poultry manure application. The results of the partial budget analysis showed that 15 t ha<sup>-1</sup> poultry manure application gave the highest marginal rate of returns. Since the highest bulb yield and maximum marginal rate of returns are obtained at 15 t ha<sup>-1</sup> poultry manure application, this rate can be recommended for onion production in the researched area, and areas having similar agro-ecologies. However, as the research is conducted for a single season and location, repeating the experiment over location and year will be required to give a conclusive recommendation.

Background: Vegetables and fruits are the main sources of a number of essential micronutrients, and therefore, information on availability and consumption of vegetables/fruits is vital in designing sustainable interventions to prevent micronutrient deficiencies, particularly that of vitamin A deficiency. Objective: The objective of the study was to assess availability and consumption of fruits and vegetables in Ethiopia.Methods: Employing, multistage cluster sampling approach, a sample of 2552 households in nine administrative regions were interviewed on availability and consumption practice of vegetables and fruits. Results: In aggregate, 41.5% and 75.5% of households did not produce/cultivate any of the common vegetables and fruits over the year preceding the survey, respectively. The proportion of households who did not produce/cultivate vegetables was high in Addis Ababa (99.7%), Afar (94.9%), Dire Dawa (94.2%) and Tigray (86.4%). The proportion of households who did not produce/cultivate fruits was highest in Addis Ababa (100%), followed in Dire Dawa (95.3%), Afar (92.9%), Tigray (92.2%), Harari (83.3%) and Oromiya (81.8%). In the overall, 38.1% and 36.5% of the children studied did not eat vegetable and fruit in the week preceding the survey, respectively. Own production of fruits and vegetables was significantly better (p<0.05) in rural areas whereas their market availabilities was significantly better (p<0.05) in urban areas. Analysis of beta carotene contents indicated that kale and carrots contain high amounts (>4000μg/100gm), spinach, mango and papaya contain moderate amounts (500-800μg/100gm), while staple foods contain no or negligible amounts. Conclusions: Cultivation and consumption of vegetables and fruits is extremely sub-optimal in Ethiopia, calling for strengthened efforts to promote production and consumption of fruits and vegetables.

Horticultural produce and processed products from the developing world are becoming increasingly popular both in domestic and in international markets. Global production and exports are rising steadily. However, yield increases have been smaller than area growth and have been negligible or even negative in the least developed countries. While experience shows that horticulture can offer good opportunities for poverty reduction because it increases income and generates employment, care must be taken that small and poor farmers are not excluded from the opportunities in these market sectors. In this article, we argue that development agencies must put more emphasis on horticultural research and development, especially in the following priority areas: genetic improvement, safe production systems, commercial seed production, postharvest facilities, and the urban/peri-urban environment.

This study estimates technical, allocative and economic efficiencies and identifies their determinants in smallholders' vegetable-dominated mixed farming system of eastern Ethiopia. Technical, allocative and economic efficiencies were estimated by a non-parametric data envelopment analysis method. The mean technical, allocative and economic efficiencies were found to be 91, 60 and 56%, respectively. This indicates the existence of substantial allocative and economic inefficiencies of production in the study areas. An econometric analyses based on Tobit model indicate that asset, off/non-farm income, farm size, extension visits and family size were the significant determinants of technical efficiency, whereas asset, crop diversification, consumption expenditures and farm size have significant impact on allocative and economic efficiencies. This study also reveals that the cost excess owing to inefficiency in the sample is on average 44%, mainly as a result of allocative inefficiency, which is attributed to low asset ownership and farm size, high consumer spending, crop diversification and barriers to the flow of labour between farm and off/non-farm activities.
