IMPACT OF INTEGRATED NUTRIENT MANAGEMENT ON GROWTH AND ECONOMICS OF GREEN GRAM (VIGNA RADIATA L.) UNDER PRAYAGRAJ ZONEMo Naushad, Lalit Kumar Sanodiya, Ankita Sagar and Nivedita PrasadAbstract An experiment was conducted at Agricultural Research Farm, Faculty of Agriculture & Allied Sciences, Prayagraj (U.P.), India during Kharif season of 2022 to study the impact of integrated nutrient management on growth, yield and economics of green gram (Vigna radiata L.). The experiment was carried out in randomized bock design with three replications in various permissible combinations with inorganic fertilizers, rhizobium and PSB along with FYM on green gram (Vigna radiata L.). This study revealed that 100% RDF + 5.0 tonnes FYM ha-1 + Rhizobium and PSB seed inoculation significantly increased plant height (91.99 cm), dry weight (105.45 g) and root nodules (111.33). The same treatment combination also proved most effective in improving the yield and yield attributing parameters viz., number of pods plant-1 (31.43), number of seeds pod-1 (12.46), test weight (37.26 g) and harvest index (34.90 %). Thus, application of farm yard manure @5 tonnesha-1 along with Rhizobium and PSB helped in increase in yield over control. However, application of 100% RDF along with bio-fertilizer and FYM @5.0 tonnes ha-1 significantly increase gross return (104,120.00) net returns (76,017.00) and benefit: cost ratio (2.70). These results indicate that inorganic fertilizers along with bio-fertilizers and addition of organic matter proved to be useful in achieving the yield with integrated use of different sources of nutrients. |
