Abstract

The research study titled Economic benefits of application of NPK, fermented organic manures and mycorrhiza on yield and production of green gram (Vigna radiata L.) Var. PDM-139." was conducted during the Zaid season of 2023 at the Central Research Farm, Department of Soil Science and Agricultural Chemistry, Naini Agricultural Institute, Sam Higginbottom University of Agriculture, Technology, and Sciences, Prayagraj, Uttar Pradesh, India. The experimental layout followed a 3x3 Randomized Block Design (RBD), incorporating three levels of fermented organic manure (0%, 50%, and 100%), Mycorrhiza (0%, 50%, and 100%), and N, P, K at the Recommended Dose of Fertilizers (RDF). The variety chosen was PDM-139, which was released by the State Variety Release Committee (SVRC) of Uttar Pradesh in 1974. The recorded average yield ranged from 6 to 9 quintals per hectare. The response of total seed yield of green gram recorded as influenced by different levels NPK, fermented organic manure and mycorrhizal inoculation. The seed yield of green gram was found to be increased significantly with the increase in levels of NPK, fermented organic manure and mycorrhizal inoculation. The maximum seed yield was recorded as 16.42 (q ha-1) T9 (NPK@RDF + M2@ 10Kg ha-1 50% + F2@ 50 l ha-1 50%) which was higher than any other treatment combination and the minimum seed yield was recorded as 8.76 (q ha-1) in T1 (control). However, as for the economy of different treatments is concerned, the treatment T9 (NPK@RDF + M2@ 10Kg ha-1 50% + F2@ 50 l ha-1 100%) provide highest net profit of ₹ 68139.13 ha-1 with highest cost benefit ratio is 1:1.605.

Keywords: NPK, fermented organic manure, mycorrhizal inoculation, seed yield, cost-benefit ratio
