Abstract:

A three year field experiment was conducted during the rainy season of 2014, 2015 and 2016 at farmer field in 66 locations (07 districts) of Bihar. The soil was sandy loam in texture and medium in organic carbon. The study was conducted to assess the important major nutrient for soybean crop through omission. The experiment comprised of 4 treatments, viz., T1 (100 % NPK), T2 (100 % PK, N omission), T3 (100 % NK, P omission), T4 (100 % NP, K omission). Growth and yield attributes were significantly influenced by nutrient – omission treatments and their values were higher when nutrients were applied according to recommended dose. Omission of P and K resulted in 10 and 13.47 percent reduction, respectively in grain yield. A similar trend was observed in the number of filled pods and grain yield is higher with T1 (100 % NPK) followed by T2 (100 % PK, N omission), T3 (100 % NK, P omission) and T4 (100 % NP, K omission). Plants without K produced lower average grain weight of all sites. The correlation studies between soybean grain yield and nutrients parameters showed that the soybean grain yield was positively correlated with different omission plot respectively. Results clearly proved that K is the most important nutrient for soybean, followed by P and N.
