IRON CONCENTRATION IN GRAIN AND STRAW IN RICE BY THE INCORPORATION OF EFFECT CROP RESIDUE AND RESIDUAL EFFECT OF ZINC IN THE RICE-WHEAT CROPPING SYSTEMKamini Kumari1, Anil Kumar KhippalI2 and Mercy Baranski3Abstract The present experiment is a part of a long-term experiment based on the effect of crop residue and residual starter zinc. This part of the investigation âConcentration of iron in grain and straw of rice in rice-wheat cropping systemâ indicated the synergistic effect of Zn on Fe concentration in grain and straw of rice. The interaction effects of crop residue and residual Zinc on Fe concentration in grain and straw were found non-significant. |
