In order to investigate the response of Vermiwash+RDF on growth, yield, and economics of black gram a field experiment was carried out during the Kharif season of 2019 at Experimental Research Block of SGRR University, Dehradun, Uttarakhand. The layout of the experimental field was laid out in a completely randomized block design with 10 treatments and 3 replications. The results indicated that among all the treatments, T10 (Vermiwash 4.5%+RDF 25%) was overall found best for farmer’s point of view concerning plant height (58.67 cm), number of pods per plant (69), grain yield (15.023 q per ha), straw yield (80.88 q per ha) and harvest index 918.27%) at harvest. Results also indicated that the net return of T10 was (88215.65 Rs per ha) also good from the farmer's point of view. Based on the present investigation, it was concluded that Vermiwash 4.5%+RDF 25% improves the growth and yield of black gram crops under present agro-climatic conditions.
