Influence of INM on Growth and Yield of Green Gram (Vigna radiata L.) NEPZ

Abstract

At the United University's Agricultural Research Farm in Rawatpur, Jhalwa, Prayagraj (U.P.), India, during the Kharif season of 2022, a research on green gram (Vigna radiata L.) was carried out to examine the effects of integrated nutrient management on growth, yield, and economics. On green gram (Vigna radiata L), the experiment was conducted using a randomized bock design with three replications in all allowable combinations of inorganic fertilizers, Rhizobium, and PSB together with FYM. This study showed that plant height (91.99 cm), dry weight (105.45 g), and number of root nodules (111.33) were all significantly enhanced by 100% RDF + 5.0 tonnes FYM ha-1 + Rhizobium and PSB seed inoculation. In terms of increasing yield and yield-related indicators, such as number of pods plant-1 (31.43), number of seeds pod-1 (12.46), test weight (37.26 g), and harvest index (34.90%), the same treatment combination likewise showed the best results. As a result, adding farm yard manure at a rate of 5 tonnes per hectare coupled with Rhizobium and PSB increased yield compared to the control. But using 100% RDF, bio fertilizer, and FYM @ 5.0 tonnes ha-1 greatly boosts gross returns (₹ 104,120.00), net returns (₹ 76,017.00), and benefit: cost ratio (2.70). These results showed that the addition of organic matter, inorganic fertilizers, and bio-fertilizers all combined to boost yield while using various nutrition sources.
