| Abstract: | Summary In a field experiment, more than 22% increase in the grain yield of corn was obtained by the application of 50 kg ZnSO4/ha. Grain yields were also increased by increasing the level of applied phosphorus. Positive relationship was obtained between
Zn and P, the phosphorus treatment increased Zn uptake by grains and vice versa. |
