Response of Peach （Prunus persica） cv. to Foliar Application of Potassium and Copper

The experiment was carried out in a private orchard situated at Atrush town, Duhok Govemorate Kurdistan Region-Iraq during 2011 season to study the effect of foliar application of three concentrations of potassium （0.0%, 0.5% and 1%） and three concentrations of copper （0.0%, 0.02% and 0.04%） on an e...

Description
Summary:The experiment was carried out in a private orchard situated at Atrush town, Duhok Govemorate Kurdistan Region-Iraq during 2011 season to study the effect of foliar application of three concentrations of potassium （0.0%, 0.5% and 1%） and three concentrations of copper （0.0%, 0.02% and 0.04%） on an eight years old peach cultivar, planted in clay soil, spaced at 4.0 m x 4.0 m. The foliar application was done twice, on April 24, 2011 and May 25, 2011. The results showed that spraying of potassium at both concentration （0.5% and 1%） or copper at high concentration （0.04%） had a positive effect on leaf area, leaf fresh weight, leaf dry weight, total chlorophyll, fruit weight, fruit number and yield per tree as well as fruit diameter, pith thick, pulp weight, seed weight and total soluble solid. The interaction between potassium and copper significantly enhanced all detected traits, since trees receiving 1% and sprayed with 0.04% of copper was characterized by the highest values of all growth and yield characterist
