Response of Wheat to Zinc Application in Alluvial Soils of Morena District, Madhya Pradesh

The effect of zinc application on yield, and zinc concentration and its uptake by wheat was studied. About 78% deficient soils and 11% marginal soils significantly responded to Zn application and also resulted in significant increase in zinc concentration and its uptake by wheat. The DTPA extractable Zn of soils was found to be significantly correlated with Bray's per cent yield values and its concentration of 0.46 ppm may be considered critical for separating zinc deficient and non-deficient soils. Furthe., a concentration of 18 ppm Zn in 3rd leaf of wheat taken from top of the plants was found critical below which response to applied zinc is expected.
