EFFECT OF CR AND AMENDMENTS ON YIELD AND MICRONUTRIENTS CONTENTS IN DIFFERENT PARTS OF WHEAT

J. K. PARMAR AND K.P. PATEL

Abstract

A pot-house experiment was carried out at Micronutrient Project, AAU, Anand to study the effect of Cr levels (0, 10, 20, 40, 80 and 160 mg kg-1 soil) in presence and absence of amendments (FYM and gypsum) on wheat on coarse loamy soil with three replications under factorial completely randomized block design. The Cr application at Cr10 level; and the increase was by 9.2 per cent over control whereas Cr80 level reduced grain yield significantly by 78.11 per cent over control. It was observed that plant could not survive at Cr160. Similar results were also noted in straw yield of wheat. The grain and straw yield were improved due to application of FYM and gypsum. The harmful effect of Cr was minimized to some extent at lower level of Cr i.e. Cr10 applied along with amendments. The Fe, Mn, Zn and Cu content of husk, grain, root and straw, increased up to Cr10 due to effect of Cr at Cr10; thereafter it significantly decreased. Similar results were also found in case of Mn content of root up to Cr20 level. The Zn, Cu and Mn content of straw, husk and root were found to be decreased with increase in Cr levels. The FYM significantly increased Mn, Zn and Cu content in grain, Fe, Mn, Zn and Cu content of straw, Fe and Mn content of husk and Fe, Mn, Zn and Cu content of roots of wheat over control. However, the effect of FYM was at par with gypsum in most of the cases. Similarly, effect of gypsum enhanced the increased of Fe content of wheat grain as well as Zn and Cu content of wheat husk over control being at par with FYM. The micronutrients content in different parts of wheat were not influenced due to effect of Cr X Am interaction, except Cu content of wheat husk.
