Effects of Iron Sulfate, Zinc Sulfate, Iron Chelate, Powder Sulphur and Humic Acid Applications on Vegetative Growth of Sweet Cherry (Prunus avium L.)

This study was carried out in A degrees scehisar district of Afyonkarahisar on '0900-Ziraat' sweet cherry cultivar for two successive years in 2011 and 2012. Ten different applications consisting of 80 g FeSO4.7H(2)O tree(-1), 20 g FeEDDHA tree(-1), 420 mL TKA degrees-Humas tree(-1), 80 g FeSO4.7H(2)O + 420 mL TKA degrees-Humas tree(-1), 200 g powder sulphur (S) tree(-1), 80 g FeSO4.7H(2)O + 200 g powder S tree(-1), 25 g ZnSO4.7H(2)O tree(-1), 25 g ZnSO4.7H(2)O + 420 mL TKA degrees-Humas tree(-1) and 25 g ZnSO4.7H(2)O + 200 g powder S tree(-1) were subjected for determination of their effect on vegetative growth of sweet cherry. In this study, shoot diameter, shoot length, leaf total chlorophyll content, leaf area and leaf iron (Fe) and zinc (Zn) contents were obtained. Shoot length, shoot diameter and leaf area showed general increases in 80 g FeSO4.7H(2)O + 200 g powder S tree(-1) and 25 g ZnSO4.7H(2)O + 200 g powder S tree(-1) treatments. The results clearly indicated that he treatments had different effects on the shoot length and shoot diameter although there was a differences between the experimental years. Particularly, significantly positive effects of the treatments on leaf total chlorophyll was apparent for the second year's observations. In addition, Fe and Zn concentrations in leaf were markedly increased in response to the treatments.
