Effect of fertility levels on growth, yield and quality of soybean [glycine max) genotypes

A field experiment was conducted during rainy seasons of 2009 and 2010 to study the effect of fertility levels on growth, yield and quality of soybean genotypes. Among the early genotypes of soybean, JS 81–1504 proved the most suitable which yielded 11.75 q/ha with net income upto Rs. 14291/ha having 40.71% protein and 20.71% oil in grain. The most balanced and economical fertility level for the early soybean genotypes was N₃₀P₆₀S₄₀Zn₁₀ which gave the highest grain yield (12.86 q/ha) and net return (Rs. 15572/ha), grain protein (42.32%) and grain oil (22.08%). The genotype JS 81–1504 grown with the highest fertility level (N₃₀P₆₀S₄₀Zn₁₀) further augmented these parameters.
