Abstract

Comparative study was performed to evaluate the vermicomposting efficiency of two earthworm species Eisenia fetida, Eudrilus eugenia from the garden wastes, vegetable market wastes. Three different experimental works were conducted. For each experiment three plastic vermibins were used. Experiment (1) mentioned for control without earthworms. Experiment (2) bedded with Eudrilus eugenia, Experiment (3) comprised of bedding with Eisenia fetida. Pre composting was allowed for 10 days after that Eudrilus eugenia, Eisenia fetida were added in respective vermibins. The multiplication of earthworms in terms of number was calculated at the end of vermicomposting. The N, P, K value of the manure in each vermibin was estimated before and after the completion of the experiment. High N, P, K value was obtained in Experiment (2) and Experiment (3) compared to control. Among the solid wastes, the vegetable wastes were degraded quickly by Eudrilus eugenia and also it has the best quality of manure. Eudrilus eugenia was found to be efficient for quick degradation of both garden wastes and vegetable wastes. After manure production, field trials were conducted using different fertilizers to assess the manure quality in the growth and yield of tomato plants. Six types of experimental trial pots were prepared where one was kept as control and five others were treated with different category of fertilizers. The treatment pots (P3) showed better growth parameters (leaf numbers, stem diameter, plant height) than the rest of the trial.
