Presowing soaking of wheat seeds in copper and manganese solutions

Abstract
Presowing soaking of wheat seeds in CuSO4 and MnSO4 solutions increased the grain yield with increasing concentrations of these solutions. Seed soaking in 0.1% CuSO4 or 0.2% MnSO4 solution for 12 hrs gave the highest grain yield. The Cu and Mn content of the grain increased with increasing concentrations of these solutions. Whereas N and P contents were not significantly affected, but K content increased significantly due to the Cu treatment.
