Abstract
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.
