Abstract

A green house experiment was conducted on a Zn deficient sandy soil, to study the effect of FYM (10 and 20 t/ha), wheat straw 5 and 10 t/ha and Zn levels (0, 12.5, 25.0 and 50.0 kg. Zinc sulphate /ha) on the yield, content and uptake of Zn by wheat (HDM-1553) and hybrid maize (ganga-5) grown in succession. Application of FYM and wheat straw increased the yields of both wheat and maize crops. The magnitude of increase in yield of wheat crop was more with FYM than with wheat straw. Higher level of wheat straw showed more increase in second crop of maize and indicated a residual effect. In absence of organic amendments, application of Zn increased the yield of both the crops. Application of organic amendments increased the content and uptake of Zn in wheat and maize crops. Application of FYM showed higher values of content and uptake of Zn in wheat and maize crops. Application of FYM showed higher values of content and uptake than wheat straw. Increased application in levels of Zn increased the content and uptake of Zn in both the crops.
