ABSTRACT

Compost is organic matter that has been decomposed and recycled as a fertilizer and soil amendment. Compost is a key ingredient in organic farming. Vermicompost is the product or process of composting through the utilization of various species of worms, usually red wigglers, white worms, and earthworms. With the proper mixture of water, oxygen, carbon, and nitrogen, microorganisms are allowed to break down organic matter to produce biocompost. In the present study, the seedling of Vigna radiata were transplanted in four pots of equal size, which were noted as T1- (Biocompost), T2- (Vermicompost), T3-(Biocompost + Vermicompost) C- (Control). The uninoculated treatment was denoted as control. The combined inoculation of Biocompost and Vermicompost could enhance the morphological parameters such as height of the plant, number of leaves, number of nodules, shoot length, root length, number of roots, were analysed at different time intervals (15th ,30th ,45th and 60thdays) and biochemical constituents such as Chlorophyll, Carbohydrate, Protein, Carotenoids contents were analyzed at 60th days. Compare to all treatments, the combined inoculation of Vermicompost + Biocompost (T3) showed better response in all the parameters was tested. To prevent the environmental pollution from extensive application of chemical fertilizer, the Vermicompost and Biocompost could be recommended to farmers to insure the public health and a sustainable agriculture.
