EVALUATING THE INFLUENCE OF VARIED SYNTHETIC FERTILIZER CONCENTRATIONS IN CONJUNCTION WITH VERMICOMPOST AND FYM ON THE GROWTH, YIELD, AND ECONOMIC ASPECTS OF BLACK GRAM (VIGNA MUNGO) CULTIVATION IN THE DEHRADUN REGION OF UTTARAKHANDSRI LIKHITHA GUDLA, MANISHA VARIKUPPALA, NIKHITHA DEVARAKONDA AND SUMIT RAYAbstract To explore the effects of vermicompost, farmyard manure (FYM), and synthetic fertilizers on the growth, yield, and economics of black gram cultivation, a field experiment was conducted during the summer season of 2019-20 at the Research Block of Uttaranchal University in Dehradun, Uttarakhand. The experimental layout followed an incomplete randomized block design featuring ten treatments and three replications. The findings highlighted that among all the treatments, Treatment T10, which consisted of 75% Vermicompost, 50% FYM, and 50% recommended dose of fertilizer (RDF), emerged as the most favourable option from the farmerâs perspective. It exhibited notable improvements in various parameters, including plant height (58.67 cm), straw yield (80 q/ha), the number of pods per plant (69), and grain yield (15.023 quintals per hectare) at harvest. Furthermore, Treatment T10 also yielded a commendable net return of 88,215.65 Rs per hectare, which is economically advantageous for farmers. Based on the results of this study, it can be concluded that the combination of 75% Vermicompost, 50% FYM, and 50% RDF significantly enhances the growth, yield, and overall economic viability of black gram cultivation, especially in the agroclimatic conditions of Dehradun. |
