Growth Parameters, Biomass Production and Nutrient Uptake by Greengram as Influenced by Potash and Zinc Levels

A field experiment was conducted during kharif season at Rahuri, to study the effect of potash and zinc on greengram. Both potash and zinc affected the seed yield and yield attributes significantly. Application of potash @ 25 kg ha-1 and zinc @ 15 kg ha-1 were found optimum to obtain significantly more number of primary branches per plant, dry matter production and yield. Application of potash @37.5 kg ha-1 and zinc @ 15 kg ha-1 recorded significantly more uptake of zinc by greengram crop.
