The experiment was conducted to evaluate the effect of copper on wheat growth and soil composition through its soil and foliar application. For -1 this purpose, non-saline non-sodic soil (pH = 8.10, EC = 0.85 dS m , SAR = 4.60, saturation percentage = 29 % and sandy clay loam) was collected, brought to -1 green house and filled in the pots @ 6.5 kg pot . All these pots were irrigated to achieve uniform soil column. This experiment comprised 5 treatments viz., -1 -1 control, soil application of copper @ 2 mg kg (level 1), @ 4 mg kg (level 2), foliar application of copper @ 1% solution (level 1) and @ 2% solution (level 2). These treatments were replicated thrice. All the pots were arranged using completely randomized design. Soil application of copper was done before sowing wheat seeds. Seeds of wheat (Lasani-2000) were sown and 3 plants were maintained in each pot after germination. Foliar application of copper was done at booting and tillering stage. At maturity, data regarding different yield components were noted and wheat plants were harvested. Grain yield and total biomass was also recorded. Soil samples were collected from all pots and analyzed for copper concentration by using wet digestion method. Results of the experiment indicated that soil application of copper proved better than foliar application in increasing the yield and yield components of wheat. Similarly, foliar application -1 -1 of copper at 4mg kg (T ; level 2) was better than 2 mg kg (T ; level 1).
