Effect of Different Levels of Phosphorus and Zinc on Growth and Yield of Green Gram (Vigna radiata L.) Var. Swati Swarna

Abstract

An experiment was conducted during in Zaid season (March 2022-June 2022) on central research farm of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The experiment was laid out in randomized block design with three levels of Phosphorus and Zinc (0 %, 50 % and 100 %). The treatment combinations were replicated three times and were allocated at random in each replication. The result shows that application of different levels combination of inorganic fertilizers increased growth, yield of green gram. It was recorded from the application of P and Zinc fertilizers in treatment T7 [P @ 100% + Zinc @ 0%] maximum plant height 40.90, 49.12, and 60.16 cm at 30, 60 DAS and at harvest, number of branches plant-1 9.35, 11.62, and 14.24 at 30, 60 DAS and at harvest, number of pods plant-1 25.73, number of seeds pod-1 10.54, test weight of 1000 seeds 54.66 g, grain yield 11.73 q ha-1 with benefit cost ratio 1: 2.33 best from T1 [(control) P @ 0% + Zinc @ 0 %].
