Effect of Vermicompost on Growth, Yield and Quality of Vegetable Crops
Publication Date : 20/08/2015
Vermicomposting is a promising method of transforming unwanted and virtually unlimited supplies of organic wastes into usable substrates. In this process, the digestive tracts of certain earthworm species (e.g., Eisenia fetida) are used to stabilize organic wastes. The final product is an odorless peat-like substance, which has good structure, moisture-holding capacity, relatively large amounts of available nutrients, and microbial metabolites that may act as plant growth regulators. For these reasons, vermicompost has the potential to make a valuable contribution to soilless potting media. The objective of this study was to evaluate the transplant quality and field performance of vegetable transplants grown in vermicompost. Tomato (Lycopersicon esculentum Mill.), Eggplant (Solanum melongena L.), Pepper (Capsicum annuumL.), Potato, Sweet corn hybrids, Pak choi, Spinach and Turnip. Growth of vegetable transplants was positively affected by addition of vermicompost, perhaps by altering the nutritional balance of the medium. Transplant quality was improved in peppers and eggplants while tomato transplant quality was slightly reduced. There were no significant differences in field performance. Hence, vermicomposting is a sustainable technique for solid waste disposal. Vermicomposting is the science of producing compost from biodegradable organic matters through earthworms. Vermicompost contains significant quantities of nutrients, a large beneficial microbial population and biologically active metabolites, particularly gibberellins, cytokines, auxins and group B vitamins which can be applied alone or in combination ith organic or inorganic fertilizers so as to get better yield and quality of diverse crops. Key Word: Vermicompost, Yield, quality, Tomato, Sweet peaper, potato, Sweet corn hybrids, Pak choi, Spinach and Turnip.
