Özet

This study was carried out to determine the effect of deficit irrigation on seasonal changes in leaf nutrient concentrations of 'Braeburn' apple variety. The study was conducted during 2010-2011 growing seasons under six different deficit irrigation programs. In order to determine nutrient variations during the growth period depending on irrigation programs, leaf samples were taken in five periods (May, June, July, August and September) and nutrient concentrations (N, P, K, Mg, Ca, Fe, Zn, Mn and Cu) were determined. Leaf nutrient concentrations significantly varied with irrigation treatments and seasonal changes. The plant nutrient values of commercial irrigation treatment were higher than whole deficit irrigation treatment levels generally. Nitrogen, P, K, Ca and Zn concentrations decreased under deficit water conditions compared to commercial irrigation treatments. However, micronutrient treatment had no effect on the concentrations. The optimum nutrient demands and uptakes changed with different periods.
