Abstract

Abstract Chemical manipulation was able to induce higher productivity in soybean through improved dry matter accumulation, increased source activity, retarding leaf senescence and yield components. The senescence percentage was negatively correlated with yield (r =−0.7669**) while the source activity was positively associated (r =+0.9167**). All the yield components had significant positive correlation with yield. The low cost urea and coconut water, foliar feeding at peak flowering and late grain filling stages improved the productivity in soybean. The maximum beneficial effect of foliar feeding was noticed in the soil where the absence of native nodulation was observed.
