... Melons and other cucurbit crops benefit from mulching in an open field, with tunnels and greenhouses, useful for obtaining early yields and fruit quality (Cozzolino et al., 2023). For greenhouse cucumber crops in a conventional system, the soil needs to have a light texture to ensure aeration of the roots and good drainage, such as mineral wool as nutrient substrate of crops (Becherescu et al., 2016;Petre et al., 2015). Applying mulching treatments increased yields and fruit quality to sweet potato as well (Dinu et al, 2022;Hector et al., 2015;), physalis (Helaly et al., 2017), watermelons (Singha et al., 2023, and lettuce (Tiru et al., 2018), etc. ...
Cucumber (Cucumis sativus L.) is a species of the Cucurbitaceae family cultivated mainly in protected areas in Romania. Cucumber fruits are sources of nutrients necessary for human health, and awarness of quality attributes can satisfy the demands of consumers who are becoming more informed lately. The aim of the study was to analyze of some quality indices in two hybrids of cucumbers, Amour F1 and Capricorn F1 grown in solar, on a soil mulched with black polyethylene film. The quality analyzes were performed immediately after harvesting, at technological maturity and were focused on: ph, titratable acidity, SSC, reducing sugars, glucose, fructose, ascorbic acid, total phenolics and flavonoids content. The results showed that the hybrid Amour F1 recorded higher values in terms of content in SSC, ascorbic acid and total phenolics and in mulched variants compared to the variantes without mulching.
... Also, weed control cannot be avoided [9]. Therefore, it is needed to treat soil using different methods which are either too expensive or too polluting to the soil and/or groundwater [13]. ...
Purpose
Soilless culture and using organic wastes can increase not only yield but also quality and safety of fresh produce and thus meet the demands of modern society.
Methods
In order to study the effect of new organic-based soilless media including aged wood bark, composted date palm woody wastes, and a mixture of 70% cocopeat + 30% perlite as the control on yield, quality, and nutritional status of greenhouse cucumber, this study was conducted as randomized complete blocks design with three replications.
Result
Based on the results, the average daily yield was not significantly affected by the studied organic wastes. Although aged wood bark had the highest total yield, the number of fruit and average fruit weight compared to other treatments; however, there was no significant difference between the three-growing media in terms of yield parameters. The nitrate content of fruit in all treatments was lower than the permissible limit. Furthermore, regardless of the type of growing media, the accumulation of nitrate in fruit peel was greater than in the fruit flesh by 3–7 times.
Conclusion
In general, it is concluded that both aged wood bark and composted date palm woody wastes may be considered as the alternative options for cocopeat and perlite.
Graphical Abstract
... In addition, these seeds are a good source of minerals and used in diet and disease treatment programs (Murad and Nyc, 2016). This explains why cucumber is one of the creeping vegetables with large consumer demand worldwide (Petre et al., 2015). World's cucumber production is over 40,000 tons, China being the leading producer (Abdul and Khan, 2015). ...
... As a rule of thumb, the soil is usually the most available growing medium for plants because it provides anchorage, nutrients, air, and water for successful plant growth and for microorganisms (Sepehri et al., 2018). However, the crops on soil encounter major problems due to pathogen attacks and soil limiting factors (Petre et al., 2015). This is truly the case of the Abidjan city (Côte d'Ivoire), a megalopolis which most vegetable production is provided by peri-urban cultivation. ...
Cucumber (Cucumis sativus L.) is a plant of great importance for food, agriculture, economy and medicine. This importance explains its high demand, intensified by its cultivation conditions, particularly the growing rarity of fertile land and available water. To contribute to this species yield optimization, the effects of fertilizers type [chemical: NPK (12-22-22) and organic: Agribionate] and a control (C) combined to two watering modes (traditional sprinkler and bottle drip) on plants growth and yield have been studied from sowing to harvest. Plant growth (stem length and diameter at the collar, number of leaves and flowers per plant, leaf area) and yield (fruit weight, diameter and length, yield) were assessed. ANOVA2 tests revealed that fertilization (NPK and agribionate) favored plant growth (respectively 34.20 and 37.32 cm in height against 6.67 cm) and increased yield (7498, 66 and 6600.46 Kg/ha against 1558 Kg/ha) with the largest and heaviest fruits (145.69 and 142.80 g) compared to the control (C) that produced the smallest ones (59.35 g). About watering, the bottle drip mode was more beneficial than traditional sprinkler one for cucumber organ growth and plant yield. The interaction (fertilizer type × watering mode) indicated that the best results were obtained with the Agribionate fertilizer watered with the bottle drip method.
... To improve the survival rate of seedling transplants and to promote their growth, botanists have conducted research on seedling containers of various shapes and materials, such as seedling-raising plates and seedling containers. Various types of plastic seedlingraising plates, paper seedling containers, and biodegradable seedling containers have been developed (Evans and Karcher 2004;Salvador et al. 2005;Bai et al. 2008;Petre et al. 2015). The materials used to produce these transplant pots may include non-degradable plastics derived from petroleum; environmentally compatible plant fibers, such as corn stalk or rice straw (Li et al. 2000;Zhang et al. 2011); biodegradable adhesives (Wu et al. 2013), such as soy proteins (Qu et al. 2015); biological resins; lactic acid (Lubick 2007); and organic wastes, such cow dung and shells (Evans and Hensley 2004). ...
Biomass seedling containers were prepared from agricultural field wastes (i.e., rice straw and corn stalk) and cow manure, mixed with a starch adhesive. Based on the ratio of raw materials, different models of seedling containers were designed and tested. The performance of the seedling containers was characterized by measuring their forming ability in the mold, water absorption, air permeability, density, and various physical and chemical properties. The results showed that the percentage of well-shaped containers formed in the mold could reach as high as 98% when the ratio of rice straw to cow dung was 1:15, and the moisture content of the containers was approximately 15%. As the straw or stalk content increased, the percentage of seedling containers having good shape and compactness decreased, whereas the air permeability and water retention values increased. At the same mixture ratio, rice straw seedling containers were better than corn stalk seedling containers. The nutrient content of the seedling containers was over 10 times that of the soil surrounding the container, which could contribute to the conservation of soil fertility, as well as the seeding and transplanting of species in the process of ecological restoration.
... Cucumber (Cucumis sativus L.), belongs to the Cucurbitaceae family, one of the most important plant families in agriculture, and one of the basic crops in the greenhouse were being grown on a large scale worldwide (Papadopoulos, 1994). It is one of the creeping vegetables with large consumer demand worldwide (Petre et al., 2015). In addition, it is considered one of the vegetable crops widely cultivated in plastic greenhouses in the Mediterranean region, because of its short growing cycle and its high economic value in off-season harvest (Maršić and Jakše, 2010). ...
... Since the crops on soil show major problems due to pathogen attacks and soil limiting factors, it is required to conduct soil treatments using either chemical or thermal methods that are not environmentally friendly. Moreover, these methods of disinfection are either too expensive or too polluting to the soil and/or groundwater (Petre et al., 2015). Besides, other problems such as nematodes, unsuitable soil reaction, unfavorable soil compaction, poor drainage, degradation due to erosion, salinity, etc. all reduce yield. ...
... The peat produced TSS of 3.6 (Brix), while in perlite the TSS was (3.5) Brix. The results in Table 2 and 3 were compared to Petre et al. (2015) where they used perlite and jiffy (peat) in 50-50% ratio. They showed a variation of 140 mg/100g vegetal in chlorophyll content. ...
This experiment was conducted during spring growing season of 2018 at Jordan University of Science and Technology (JUST) campus in northern Jordan 32.4950° N, 35.9912° E. The aim of the study was to evaluate the effect of different soilless media such as T: Tuff 100%; TP: Tuff + Perlite 50% each; TPS: Tuff + Perlite + Sawdust 33% each; and TS: Tuff + Sawdust 50% each on some of morphological, physiological and biochemical characteristics related to the quality and quantity of seedless and baby cucumber cultivars. The experimental design was split plot with factorial arrangements and four replications. The measurements related to plant morphology: height, shoot and root length, shoot root fresh and dry weight, number of leaves and flowers, fruit quality: total yield, weight, diameter, hardness, length and numbers per plant. Fruit total soluble solids, the potential of hydrogen pH and electrical conductivity EC of fruit juice, leaf chlorophyll content, leaf relative water content and fruit water content, fruit and shoot biochemical content minerals, organic matters, fats, fibers, and proteins were also measured. The results indicated significant differences in both cucumber cultivars with respect to all parameters studied. Finally, this study concluded that using TS media for seedless cultivar is the best successful growing soilless media as well as the cheapest compared to other solid media used. On the other hand, using TP media for baby cultivar was the superior growing soilless media that was not expensive compared to other universal media. In addition, the TPS media showed minimum growth and low yield in both cucumber cultivars.
