Abstract

Nutrient disorders in saline-sodic soils can adversely affect crop growth. In order to evaluate the growth response of wheat (Triticum aestivum L.) to Cu and Zn and the phytoavailability of these essential elements, a pot experiment was conducted in three different textured saline-sodic soils [sandy loam (SL), sandy clay loam (SCL) and clay (C)] having an ECe 8.63, 8.80, 8.98 dS m–1 and SAR 21.66, 23.48, 24.84 (mmol L–1)1/2 respectively. Seven treatments including levels of Cu (4, 6 and 8 mg kg–1) and levels of Zn (4, 6 and 8 mg kg–1) were separately applied together with a single control treatment. Dry matter yield (straw + grain) of wheat increased up to 35.2% with Cu and up to 31.2 % with Zn application relative to the control. As soil clay content increased, dry matter yield decreased up to 39.2% in SCL and up to 62.7% in C soil when compared to SL soil. Application of Cu increased the concentration in both wheat straw and grains up to 2.46 and 2.20 mg kg–1 DW respectively relative to the control. Zinc concentration in wheat straw and grains was also increased up to 29.97 and 29.40 mg kg–1 DW respectively relative to the controls. Copper application significantly increased Zn concentrations in wheat plants.
