RESPONSE OF PHOSPHORUS LEVELS AND BIO-FERTILIZERS ON THE GROWTH, YIELD AND ECONOMICS OF GREEN GRAM (VIGNA RADIATA L. WILCZEK)Aakash Malik, Pradeep Kumar Knaujiya, Awadhesh Kishore, Jaidev Sharma and Abhinandan SinghAbstract The field experiment was conducted during the kharif season of 2022 at the Crop Research Centre, School of Agriculture, ITM University, Gwalior, (M.P.) to investigate the effect of phosphorus levels and biofertilizers on growth and yield of green gram. The experiment consists of three levels of phosphorus (20, 40, 60 P2O5 ha-1) and three treatments of biofertilizers (PSB, Rhizobium and PSB + Rhizobium) and absolute control was laid out in Factorial randomized block design with three replications. The results revealed that application of 60 kg P2O5 ha-1 recorded significantly highest plant height, number of leaves plant-1, number of primary and secondary branches plant-1, number of nodules plant-1, weight of nodules plant-1 and dry matter accumulation plant-1 and seed yield and it was found at par with 40 kg P2O5ha-1 and in biofertilizers when PSB + Rhizobiumis combined used resulted in highest growth attributes and yield of green gram. Thus, for green gram cultivation, application of 60 kg ha-1 phosphorus and treatment of Phosphate solubilizing bacteria + Rhizobium (was found to be most promising treatment in enhancing the yield in green gram. Among all the treatment combinations, T10- treatment recorded maximum value of gross return, net return and benefit cost ratio. |
