Yield Attributes, Yield and Economics of Sesame and Potato under Sesame - Potato Sequence as Influenced by Nutrient Management Practices

Abstract

The present investigation on response of organic nutrient management on the yield attributes, yield and economics of sesame and potato crop in sesame-potato sequence in Gwalior regions was conducted at ICAR, Central Potato Research Institute-RS, Gwalior (M.P.) during two consecutive years (2020-21 and 2021-22). The experiment was laid out in Randomized Block Design (RBD) with four replications having 7 treatments. The treatments comprised of decomposed crop residue @ 25 t ha-1 with biofertilizer (Azotobacter and PSB), FYM @ 25 t ha-1 , vermicompost @ 7.5 t ha-1 , neem cake @ 5 t ha-1 in different treatments in addition to control, 100% RDF and INM (100% RDF + FYM @ 25 t ha-1). The results revealed that among all the organic manures, RDF and integrated treatment T 7 (100% RDF + FYM 25 t ha-1) showed better results in phenological parameters like days to flower initiation (50.3 and 51.6), days to 50% flowering (55.9 only 2021-22), days to capsule initiation (64.4 and 65.5) and days to 50% capsule formation which were numerically higher with 100% RDF NPK during 2020-21 and T 3 + vermicompost @ 7.5 t ha-1 (71.4) during 2021-22 as compared to other treatments. Yield and yield attributing characters were noted significantly higher under 100% RDF + FYM @ 25 t ha-1 viz., number of capsules plant-1 (92.4 and 83.5, respectively), seeds capsule-1 (72.4 in 2020-21) but capsule length was showed non significant effect under different treatments. Seed (944 and 870 kg ha-1) and stover yields (3013 and 2980 kg ha-1) in sesame were recorded highest under 100 % RDF + FYM @ 25 t ha-1 crop during 2020-21 and 2021-22, respectively. Application of 100% RDF + FYM @25 t ha-1 gave significantly higher yield attributing characters viz. number of tubers plant-1 (12.13 and 10.45), fresh weight of tuber plant-1 (522.9 and 508.2 g) and dry weight of tuber plant-1 (103.2 and 97.4 g) which were significantly superior over other treatments. Tuber yield (44.2 and 47.2 t ha-1) of potato during 2020-21 and 2021-22 were also highest under 100% RDF + FYM @ 25 t ha-1. Highest harvest index was recorded with T 3 + neem cake @ 5 t ha-1 (84.5%) which was significantly higher than 100% RDF NPK and 100% RDF + FYM @ 25 t ha-1 during 2020-21. However, it was highest with T 3 + FYM @ 25 t ha-1 during 2021-22 which was significantly higher than 100% RDF + FYM @ 25 t ha-1. Application of crop residue @ 25 t ha-1 + Biofertilizer (Azotobacter + PSB, @ 1 l ha-1 , each respectively) produced the highest net returns (`53144 and 44360 ha-1) in sesame crop during first and second years, respectively. Application of T 3 + FYM @ 25 t ha-1 obtained the highest net returns (`438334 and 402240 ha-1) in potato crop during first and second years, respectively. Thus, organic production of sesame and potato under sesame-potato sequence may be taken as economically viable options.

INTRODUCTION
Sesame (Sesamum indicum L.) is the vintage oilseed
crop cultivated in most of the states of India. This crop
is cultivated almost throughout India for its high-quality
oil and it has magnificent potential for export. It is
known as “the queen of oils”. It is cultivated on large
area in the states of Maharashtra, Uttar Pradesh,
Rajasthan, Orissa, Andhra Pradesh, Madhya Pradesh,
Tamil Nadu, West Bengal, Gujarat, Karnataka, Kerala,
Bihar, Assam and Punjab and to a limited extent, in
Tripura and Himachal Pradesh. It is gaining abundant
importance on account of its high economic value as
edible oil, protein, calcium, iron and methionine (Gupta
et al, 1998). The two important reasons for low yield of
sesame in our country are found to be low fertility
status of soil and non- application or devoid of proper

nutrient management in its production (Teshome,
2016). Potato (Solanum tuberosum L.) is an important
annual, herbaceous, tuber crop of Solanaceae family
that contains all the essential food ingredients required
for maintaining proper human health. It is known as
“Poor man’s friend”.
Due to high cost of chemical fertilizers, marginal
farmers face problems in cop production to desired
level. Therefore, efforts should be made to follow up
integrated nutrient management approach for efficient
utilization of chemical fertilizer through
supplementation with organic manures or altogether
organic nutrition of soil. Chemical fertilisers are
commonly used in sesame and potato cultivation due to
their rapid release of essential elements for the crop,
which has some negative effects on phenological
character, quality parameters viz. oil%, starch% etc. as
well as negative effects on soil health, water and the
environment. Organic manures are an excellent and
balanced source of nutrients that improve soil health
and environmental safety in addition to increasing
nutrient uptake.
Organic and inorganic fertilizers are important for
agricultural sustainability because of their possible
beneficial effects on soil properties and long-term soil
productivity. Several studies have been conducted to
assess the effects of organic and inorganic fertilizers on
soil properties and crop yields, and different agronomic
and environmental outcomes have been observed
depending on the specific agroecosystem (Saha et al.,
2008).
Keeping the above facts in view, the present experiment
was planned to study the response of organic manures
on the sesame and potato under Gwalior region of
Madhya Pradesh.
MATERIALS AND METHODS
The present investigation was conducted in two
cropping seasons of 2020-21 and 2021-22 at ICAR
Central Potato Research Institute –RS, Gwalior (M.P.).
Gwalior is located at 26o13’ North latitude and 78o14’
East longitude and 206 metres above mean sea level.
Gwalior lies in the North tract of M.P. enjoying
subtropical climate, with extreme hot up to 48°C in
summer and minimum temperature as low as 4.0°C
during winter season. The annual rainfall ranges
between 750 to 800 mm, most of which received from
end of June to end of September, with few showers
during winter months. The experiment was laid out in
Randomized Block Design (RBD) with four
replications having 7 treatments. The treatment
comprised of T1- Control (no fertilizer), T2- 100% RDF
NPK (Inorganic fertilizer), T3- decomposed crop
residue @ 25 t ha-1 with biofertilizer (Azotobacter and
PSB), T4-(T3+ FYM @ 25 t ha-1), T5- (T3+
vermicompost @ 7.5 t ha-1), T6- (T3+ neem cake @ 5 t
ha-1) and T7- (100% RDF + FYM @ 25 t ha-1).
Observations recorded were number of days taken from
sowing to flower and capsule initiation, number of days
from the date of sowing to the day of first flowering
and capsule formation. The sampled plants were
carefully dugged, roots were thoroughly washed under
running water, put in labelled envelop bags and taken to
the laboratory where the yield attributing characters
were recorded at maturity. Yield of crops were
calculated from net plot area and converted to per
hectare. Net monetary returns (NMR) was calculated by
the formula-
NMR (`ha-1) = GMR - COC
Where, GMR –Gross monetary return and COC- cost
of cultivation
RESULTS AND DISCUSSION
Sesame crop. Yield, yield attributing characters and
economics of crop are important index indicating the
nutrient availability, its uptake rate and photosynthetic
efficiency of the crop which ultimately influences the
crop yield. The data of both the years (2020-21 and
2021-22) pertaining to day of flower initiation of
sesame as influenced by different nutrient treatments
are given in (Table 1 and 2).
Application of nutrients indicated that the treatments
exert significant effect on days to flower initiation and
50% flowering. Application of 100% RDF + FYM @
25 t ha-1 recorded numerically maximum days to flower
initiation (50.3 & 51.3) during 2020-21 and 2021-22
which was at par with all treatments except control (no
fertilizer) and crop residue @ 25 t ha-1 + biofertilizer
(Azotobacter + PSB, @1L ha-1 each, respectively). Days
to 50% flowering was statistically same during 2020-
21. During 2021-22, highest 50% flower (55.9) counted
were recorded with T3+ vermicompost which was at
par with 100% RDF NPK, T3+ FYM @ 25 t ha-1 and
100% RDF + FYM @ 25 t ha-1. Different nutrients
indicates that the treatment had significant effect on
days to capsule initiation and 50% capsule formation.
Application of 100% RDF + FYM @ 25 t ha-1 recorded
numerically maximum days to capsule initiation (64.4
& 65.5) during 2020-21 and 2021-22. During 2020-21,
highest number of 50% capsule formation (70.8) was
recorded with 100% RDF NPK which was significantly
higher than control, crop residue @ 25 t ha-1 +
Biofertilizer (Azotobacter + PSB, @1L ha-1 each,
respectively) and T3+ FYM @ 25 t ha-1 during 2021-
22, 50% capsule formation was highest (71.4) with T3
+ vermicompost @ 7.5 t ha-1 which was significantly
higher than control, crop residue @ 25 t ha-1 +
biofertilizer (Azotobacter + PSB, @1L ha-1 each,
respectively) and T3+ neem cake @ 5 t ha-1. However,
minimum value of phenological characters were
observed under Control treatment during both the years,
respectively. It might be due to lesser nutrient
availability than other treatments which compelled
plants to completes their life cycle quickly. This result
is supported by Dambera et al. (2021).
Yield attributing characters like capsule length and test
weight were found non significant under different
nutrient application treatments since capsule length and
test weight (1000-seed weight) might be governed by a
genetic factor. But capsules per plant and seed per
capsule increased significantly with the nutrient
management practices.

Among the nutrient management treatments, capsules
plant-1 (92.4 and 83.5) and seed capsule-1 (72.4) were
significantly higher with 100% RDF + FYM @ 25
t ha-1 than all other treatments during 2020-21 and
2021-22, respectively. During 2021-22 highest seed
capsule-1 (67.8) were recorded with 100% RDF NPK
which was statistically same with 100% RDF + FYM
@ 25 t ha-1. Application of organic and inorganic
fertilizers produced healthy plants by providing stress
free environment for the growth and development of
crop compared to other nutrient applications.
However, sesame yield was increased appreciably in
the treatments receiving 100% RDF + FYM @ 25 t ha-1
giving significantly higher stover (3013 and 2980 kg
ha-1) and seed yield (944 and 870 kg ha-1), respectively
during first and second years (Table 4). The maximum
gross returns `113041 ha-1 was recorded under T3+
vermicompost @ 7.5 t ha-1 during 2020-21 which was
significantly higher than all other treatments.
Application of T3+ neem cake @ 5 t ha-1 recorded
maximum gross return (`107536 ha-1) during 2021-22
and which was significantly higher than all other
treatments except T3+ vermicompost @ 7.5 t ha-1.
However, maximum net returns (`53144 and 44360 ha-
1) were noted under crop residue @ 25 t ha-1 +
biofertilizer (Azotobacter + PSB, @ 1 l ha-1
respectively) during 2020-21 and 2021-22, respectively
which were significantly higher than all other
treatments. Whereas, minimum gross and net returns
were recorded under control and T3+ Neem cake @ 5 t
ha-1, respectively during both the years due to lower
production of seed yield as compared to other
treatments. Similar results were found by Ahirwar et al.
(2017); Lakhran et al. (2015); Chakraborty et al.
(2021).

Potato crop. Application of 100% RDF + FYM @ 25 t
ha-1 gave significantly higher yield attributing
characters viz., tuber plant-1 (12.13 and 10.45), tuber
fresh weight plant-1 (522.9 and 508.2 g) and tuber dry
weight plant-1 (103.2 and 97.4 g) during first and second
years, respectively at maturity. These values were
significantly higher than all other treatments during
both the years. This result is also supported by
Mohammed et al. (2018); Singh et al. (2018); Shubha
et al. (2018). Application of 100% RDF + FYM @ 25 t
ha-1 recorded significantly higher tuber yield (44.2 and
47.2 t ha-1, respectively) during both the years (2020-21
and 2021-22) compared to rest of the treatments. This
may be due to higher and balanced availability of
essential nutrients to crop plants owing to reduction in
the loses of applied nutrients through FYM. This
resulted in balanced nutrients supply and beneficial
effect of FYM in increasing the availability of various

macro and micronutrients in soil (Hashim, 2014).
However, minimum value of yield and yield attributing
characters were observed under control (no fertilizer)
treatment during both the years (2020-21 and 2021-22).
This result is supported by Mohanbabu et al. (2021).
Application of T3+ neem cake @ 5 t ha-1 gave higher
value of harvest index (84.5) during 2020-21 which was
significantly higher over 100% RDF NPK and 100%
RDF NPK + FYM @ 25 t ha-1. Application of T3+
FYM @ 25 t ha-1 gave higher value of harvest index
(83.3) during 2021-22 which was significantly higher
than 100% RDF + FYM @ 25 t ha-1. This result
supported by Narayan et al. (2013). The maximum
gross returns (`583234 and 546140 ha-1) and net
returns (`438334 and 402240 ha-1) were noted under
T3 + FYM @ 25 t ha-1 during 2020-21 and 2021-22,
respectively which was significantly higher than all
other treatments during 2020-21. However, during
2021-22 net return was statistically same with 100%
RDF NPK and 100% RDF NPK + FYM @ 25 t ha-1.
Whereas, it was minimum under control treatment
during both the years due to lower production of potato
tuber yield as compared to other treatments (Table 5).
Similarly, results were found and supported by Yadav
et al. (2017); Mukhopadhyay et al. (2021).
CONCLUSION
It may be concluded that application of 100% RDF +
FYM @ 25 t ha-1 was noted superior phenological, yield
attributes and yield resulting in higher remuneration for
sesame and potato crops in sesame - potato sequence.
FUTURE SCOPE
This study for comparing best organic option with
inorganic treatments. After completing 2 or 3 years of
cycle only then it’s possible to get significant residual
and cumulative effect from this cropping system. Its
basic purpose to enhance the soil organic carbon. The
present soil organic carbon less then equal 0.3% but for
better organic result, this needed to be raised up to 1%.
