2016
In this study effect of application of food waste vermicomposts to soil on antioxidant compounds, fruit yield and quality of sweet pepper (Capsicum annum L.) were investigated in field condition. Four vermicompost levels (0, 5, 10 and 15 t/ha) were applied to soil based on a randomized complete block design with three replications. The results showed that the highest (21.87 kg m2)and lowest (14.69 kg m2)fruit yield were achieved in plants treated with 5 t/ha vermicompost and control, respectively.Vermicompost treatments positively influenced fruit antioxidant compounds (antioxidant activity, total phenolic, carbohydrate content and total flavonoid). The highest antioxidant activity (81%) and carbohydrate content were obtained in plants treated with 10 t/ha vermicompost, while their lowest values were recorded in the control plants. Fruit quality indices (pH, titratable acidity, ascorbic acid and fruit firmness) were significantly influenced by vermicompost treatments. However, no si...

With the aim to evaluate chili pepper production, cultivar 'Ancho', with no chemical fertilizers; the effect of five different vermicompost-perlite mixes were used, under greenhouse conditions. Rates of the organic material were: 0.0, 15, 30, 45 and 60% (v:v). A single plant was grown in a 20-L pot, with drip irrigation and using water only: except for the control treatment irrigated with Steiner nutritive solution. For crop management, organic agriculture authorized products were used only, using a complete random blocks design with four replications. The evaluated variables were: plant height (PH), leaf number (LN), flower number (FN), fruit number (FrN), fruit weight (FW), fruit diameter (FD), fruit length (FL), leaf dry weight (LDW), root dry weight (RDW), limb dry weight (LiDW). Values of the evaluated variables increased when vermicompost rates applied were increased also. Variables showing statistical differences among treatments were: LN and PH, during plant vegetative stage; FN and FrN, during productive stage; FD, FL and FW, during ripening stage. FW was the highest for treatment with 60% of vermicompost but was, statistically, only different to treatments with 30% or less than that. Treatment with 15% showed less FW. On the other hand, treatment with 60% of vermicompost, a single plant yield 1345 g, being 2.77-folds higher than 15% treatment.
Effects of vermicompost application on growth and yield of hot pepper (Capsicum frutescens)
Engineering for Rural Development, 2024
In parallel with the increase in the world population, healthy nutrition becomes more important for people every day. However, Good Agricultural Practices (GAP) are also gaining importance. The main goal of our study is to reduce the level of inorganic fertilizer use. The experimental area where the study was conducted is located at 36º 31' 21'' north latitude and 32º 05' 07'' east longitude. In this study, 2 m high, 12 m long and 3 m wide plastic greenhouses with arc roofs were used. The greenhouses are naturally ventilated, unheated tunnel type greenhouses. UV-added plastic cover material was used as the cover material in the greenhouse. Hot pepper was chosen as the material. In the research, the development parameters of the hot pepper plant were examined by using different doses of one organic and one inorganic fertilizer type. Vermicompost (VC) was applied at a rate of 2,500 and 5,000 kg per hectare and inorganic fertilizer was used at a rate of 60-100-160 and 30-50-80 kg per hectare. Nine applications were carried out, including different doses of these two fertilizers, their combined use, and a control group. Plant heights, SPAD (Spectrum Authorized Dealer) values, plant diameters and yield values were measured weekly from the date the seedlings were planted in the experimental greenhouses until the end of harvest. The parameters found to be important in the variance analysis results of the data obtained from the trial subjects were compared with the Student's t test, and the application groups were determined and interpreted statistically. As a result, the effects of VC and inorganic fertilizer values on the development parameters and yield values of the pepper plant were determined. It has been determined that the plant growth parameters and productivity are higher, especially when 5000 kg of organic fertilizer and 5000+60-100-160 mixed fertilizer are used per hectare. Therefore, good agricultural practices include reducing the use of inorganic fertilizers.
Purpose This study evaluated the response of hot pepper (Capsicum annuum var. Red chili) towards cow vermicompost application under field conditions. Method Cow vermicompost was supplied in four levels (0, 5, 10, and 15 t ha-1) across the two growing seasons in 2017 and 2018. Results Vermicompost application significantly increased the plant height, internode distance, and number of lateral branches in both seasons. It was noticed that manuring with 15 t ha-1 of cow vermicompost resulted with enhancedchlorophyll contents, fruit yield, and fruit number in both years. In both seasons, the highest leaf number, fruit weight, and total soluble solids are related to the third treatment (10 t ha-1 of cow vermicompost). The results showed that 1000-seed weight and vitamin C content were affected by cow vermicompost. Data showed that manuring with vermicompost (5 t ha-1) caused the best quality components in 2017 and 2018. Conclusion the results showed that vermicompost had a significant impact on vegetative and reproductive growth and fruit quality of hot pepper.

Organic fertilization: An alternative to produce jalapeño pepper under greenhouse conditions
Emirates Journal of Food and Agriculture, 2013
The experiment was conducted during fall-winter seasons of years 2011-2012 to determine the effects of vermicompost tea (VCT) on growth and productivity of "Hechicero" jalapeño pepper plants grown under organic and synthetic fertilization in greenhouse. Five different fertilization forms were applied to plants [F1 = sand + inorganic nutrient solution (control group); F2 = sand + VCT on concentration of 10%; F3 = mixture of sand + compost (ratio 1:1; v:v) + VCT on concentration of 2.5%; F4 = mixture of sand + vermicompost (ratio 1:1; v:v) + VCT on concentration of 2.5% y F5 = mixture of sand + compost + vermicompost (ratio 2:1:1; v:v:v) + VCT on concentration of 2.5%]. Treatments F4 and F5 showed an increased yield of 70 and 45% with regard to the yield obtained with F1; the F1 and F2 yields were not statistically different at the 0.05 significance level. The fruit length and the pericarp thickness were increased until 7.55 and 7.01% in F5, respectively. These results suggest that, since there were differences in yield when using the organic and inorganic nutrient source, VCT combined with mixtures of sand + compost + vermicompost may be considered a successful alternative fertilizer for organic jalapeño pepper production in greenhouse.

Present research was carried out during the year 2014-2015 at the National Agricultural Research and Extension Institute (NAREI) to determine the effect of vermicompost and other fertilizers on the growth and productivity of pepper plants (Capsicum chinense). Plants were treated with five different treatments, namely T 1 (Promix), T 2 (vermicompost), T 3 (189), T 4 (189 + vermicompost), and lastly, control which had no fertilizers. T 1 , T 3 , and T 4 were inorganic fertilizers, and T 2 was organic. Results obtained showed that T 3 (chemical fertilizer) has a significant effect on the growth of pepper plants producing plants with better plant height, number of leaves, number of branches, stem diameter, higher fruit yield, fruit weight and fruit diameter. Plants treated with this treatment also had higher fruit yield, fruit weight, and fruit diameter. Mineral nutrients were highest in plants treated with inorganic fertilizers as compared to the organic fertilizer. Maximum chlorophyll level was present in plants treated with T 2. There were relatively high levels of pest and diseases in plants treated with chemical fertilizers, delayed flowering and fruiting period and high levels of leaf and fruit abscission as compared to plants treated with organic fertilizer (T2). Moreover, T 3 has proven to have a greater effect on the growth parameters of pepper plants but not the quality of plants produce.

Coffee vermicompost (VC) was used to evaluate the yield and quality of spinach. Coffee VC was added to a media mix v/v (0, 25, 50 and 75 %). In 2011, yield, ascorbic acid (AA) and nitrate contents were highest at 75% VC. In 2012, yield was highest at 50% VC, nitrate content was highest at 75% VC, and no difference in AA content was detected. A field study was conducted to compare four treatments [coffee VC, dairy compost, standard fertility (SFT) and no treatment (control)] for their effects on growth, yield and AA content of peppers. Coffee VC and dairy compost were applied at the rate of 22 t/ha and SFT was based on 212 kg/ha N. Yield, as well as AA content was not affected by the treatments evaluated; however, plant height and chlorophyll index were higher for VC and SFT treatments compared to dairy compost and the control.
Sustainable Urban Horticulture of Sweet Pepper via Vermicomposting in Summer Season
The need for extend the urban horticulture to cover the food security demands, to mitigate CO2 emissions and avoid the extreme heat waves drive this study to investigate the ability of using soilless culture systems, vermicomposting technology and net cover in producing vegetables in urban area in summer season. The aim of this study was to determine the effect of different vermicompost rates mixed with the standard substrate peat moss: perlite (perlite: peat moss: vermicompost (45:45:10) (Mix.10%), perlite: peat moss: vermicompost (40:40:20) (Mix.20%), perlite: peat moss: vermicompost (35:35:30) (Mix.30%) and perlite: peat moss (50:50 V/V) (Control) under three microclimate conditions (plants covered with black net, white net and without cover) on vegetative growth and yield of sweet pepper (Capsicum annuum L. cv. Reda) grown in pots culture during summer seasons of 2012 and 2013 at the Central Laboratory for Agricultural Climate, Agricultural Research Center, Dokki, Giza Governorate. Physical and chemical properties of substrates, vegetative growth and yield characteristics, agrometerological data and mineral contents were determined. The obtained data indicated that vermicomposting could contribute in mitigate CO2 emission, save the essential nutrients and energy via recycling the urban organic wastes to vermicompost. The physical and chemical properties were affected by vermicompost. The best vegetative growth and yield of sweet pepper were given by (Mix.20%) vermicompost mixture followed by (Mix.10%) and (Mix.30%) vermicompost mixture. There were also significant differences between cover net treatments in affecting vegetative growth and yield of pepper, the white net was superior for producing pepper during the summer season; while the black net gave the lowest plant growth and yield. The best treatment was (Mix.20%) vermicompost mixture with white net cover, while the lowest vegetative growth and yield were obtained by (Control) vermicompost mixture with black cover net during the two tested seasons. These results suggested that vermicomposting and green roof can be used in urban area for producing food instead of incineration the urban organic wastes or imported food from rural area and using white cover net to improve the pepper growth and productivity during summer season.

Vermicomposts, produced commercially from cattle manure, market food waste and recycled paper waste, were applied to small replicated field plots planted with tomatoes (Lycopersicon esculentum) and bell peppers (Capsicum anuum grossum) at rates of 10 t ha -1 or 20 t ha -1 in 1999 and at rates of 5 t ha -1 or 10 t ha -1 in 2000. Food waste and recycled paper vermicomposts were applied at the rates of 5 t ha -1 or 10 t ha -1 in 2000 to replicated plots planted with strawberries (Fragaria spp.). Inorganic control plots were treated with recommended rates of fertilizers only and all of the vermicompost-treated plots were supplemented with amounts of inorganic fertilizers to equalize the initial N levels available to plants in all plots at transplanting. The marketable tomato yields in all vermicompost-treated plots were consistently greater than yields from the inorganic fertilizer-treated plots. There were significant increases in shoot weights, leaf areas and total and marketable fruit yields of pepper plants from plots treated with vermicomposts compared to those from plots treated with inorganic fertilizer only. Leaf areas, numbers of strawberry suckers, numbers of flowers, shoot weights, and total marketable strawberry yields increased significantly in plots treated with vermicompost compared to those that received inorganic fertilizers only. The improvements in plant growth and increases in fruit yields could be due partially to large increases in soil microbial biomass after vermicompost applications, leading to production of hormones or humates in the vermicomposts acting as plant-growth regulators independent of nutrient supply.
