Influence of Different Sources of Phosphorus on Productivity and Profitability on Greengram (Vigna radiata L.)

A field experiment was conducted during the kharif season of 2014 at Crop Research Farm, Department Agronomy, SHIATS, Allahabad, UP to evaluate influence different sources phosphorus on productivity and profitability Greengram. The in randomized block design with 9 treatments viz. Control (No Phosphorus, 100% P through SSP, URP, 50% SSP + 75% 25% PSB inoculation, URP inoculation. greengram variety Samrat sown a spacing 30cm x 10 cm it fertilized as per requirement treatments. experimental results revealed that application seed inoculation produced significantly higher no. pods plant-1 (31.53), grains pod-1 (12.8), test weight (44 g), grain yield (1496.77 kg ha-1), Stover (2920 ha-1) protein (24.06 %). Further, recorded 32.45% compared control. Among economics, gross return (Rs 71766.82 net returns 47002.17 Benefit Cost (1.89). Thus, inoculation) found be most promising treatment enhancing
