Zinc (Zn) is the most important micronutrient required for sustainable crop production, particularly for rice and wheat crops. Therefore, on-farm trails (OFTs) were conducted at seventeen different locations during 2006-08 to evaluate the direct and residual application effect of Zn, applied through zinc sulphate heptahydrate under rice-wheat (RW) cropping sequence.
