Effect of integrated nutrient management in soybean [Glycine max (L.) Merill] under temperate condition

Abstract

A field experiment was conducted at Krishi Vigyan Kendra, Srinagar during two consecutive rainy seasons to study the effect of integrated nutrient management on soybean (Glycine max L.) under temperate condition. Eighteen treatment combinations consisting of three levels of each of recommended doses (RD) of inorganic fertilizers (50, 75 and 100% RD) and organic manures (control, FYM 10 t ha-1 and dalweed 10 t ha-1), and two levels of biofertilizers (control and dual inoculation with Rhizobium + PSB) were laid out in a randomized complete block design with three replications. Grain and straw yield increased significantly with successive increase in RD levels. Both FYM at 10 t ha-1 and dual inoculation with Rhizobium and PSB were significantly superior in comparison to dalweed at 10 t ha-1 and un-inoculation, respectively. Yield attributes (100-seed weight), number of nodules and protein content in seed also showed similar trend with that of grain yield following successive increase in RD levels. Similarly, FYM at 10 t ha-1 was found superior over Dalweed on the above yield attributes and seed quality. On the contrary, oil and lysine content in seed was higher with application of 75% RD over other levels.
