Application of Zn @ 0, 5.5 kg, 22 kg Zn ha-1, 0.1% Zn foliar application, 5.5 kg Zn + 0.1% Zn spray, increased the yield, concentration and its uptake in seed and straw in all the green gram genotypes. However, combined application of 5.5 kg Zn ha-1 + 0.1% Zn as foliar increased the straw yield by 56.4% and seed yield by 57%, which was the highest. Maximum Zn concentration in straw and seed (5.48 and 3.5 folds over control) was achieved when combined application of soil + foliar was made. Soil + foliar application of Zn increased the seed crude protein by 26.9% over control. Seed and straw Zn content showed a significant and positive correlation with all yield attributes except branches per plant.
