Abstract:
The current study, “Effect of Organic and Inorganic nutrient sources on Black gram [Vigna mungo (L.) Hepper]” was carried out at the Instructional farm, Rajasthan College of Agriculture, Udaipur, Rajasthan during kharif, 2025. Fourteen treatments with three replications were included in the randomized block design of the field study. The application of 100% RDF + vermicompost + Rhizobium + PSB (T12) resulted in significantly higher growth parameters, such as plant height, effective root nodulation and dry matter accumulations as well as yield attributes, number of pod plant-1, number of seed pod-1 and test weight. These results were statistically comparable to those of T11 (100% RDF + FYM + Rhizobium + PSB) and T10 (100% RDF + vermicompost + Rhizobium), and outperformed the remaining treatments. The treatment T12(100% RDF + vermicompost + Rhizobium + PSB) also produced significantly higher seed yield, haulm yield, biological yield, gross returns, and net returns was higher recorded in T11 (100% RDF + FYM + Rhizobium + PSB) statistically at par with T12 (100% RDF + vermicompost + Rhizobium + PSB. However, the administration of treatment T11 (100% RDF + FYM + Rhizobium + PSB) yielded the highest benefit-cost ratio that was statistically comparable to 100% RDF + vermicompost + Rhizobium + PSB (T12).

Keywords:
Vermicompost, Farm yard manure (FYM), Rhizobium, PSB.
