Foliar application of zinc sulphate to improve yield and grain zinc content in wheat (Triticum aestivum L.)

Foliar application is a promising agronomic strategy as it involves direct adsorption and loading of nutrients from leaf surface to phloem in comparatively far less quantity than soil applications. Present investigation entails the evaluation of most suitable treatment of zinc sulphate to improve growth and yield components of wheat. Significant increase in leaf length, leaf area, plant height, number of tillers, spike length, number of grains per spike, plant fresh weight, yield per plant, total soluble proteins and grain zinc content at 4 and 6 mM foliar treatments of zinc sulphate advocates 4 mM treatment more appropriate from economic perspective. Key words: Wheat, zinc deficiency, foliar application.
