Effect of inoculum,variety, phosphorus,and potassium on certain attributes of two soybean varieties at Jabalpur,M.P., India

Abstract

An experiment to determine the effect of inoculum, N, P, and K on certain attributes of two soybean varieties was conducted in 1967 at JNKW. The experimental area had no prior history of soybean production and contained few, if any, soybean rhizobia.

Plant height, height to first pod, lodging, seed quality, and seed weight were affected by applied N. Applied P had a quadratic effect upon plant height, while plant height decreased linearly with increasing levels of applied K. The effect of N was linear and applied P curvilinear upon lodging. Uninoculated plants had seed with poorer seed quality scores and lower seed weights than inoculated plants. Applied P increased seed weight. Height to first pod was higher for Bragg than for Clark 63.
