In Turkey, fruit growers have started to shift from flood irrigation to drip irrigation in apple orchards in the recent years. It was thought that such a transition might have adverse effects on nutrition of the plants throughout the transition period. In this study, effects of transition from flood irrigation to drip irrigation on nutrient uptake of the plants were investigated through leaf analyses for two years. Experiment was conducted in randomized blocks design with three replications and four trees in each replication. Flood irrigation (control) and drip irrigation with two different irrigation intervals (4 and 7 days) were compared. Leaf samples were collected in the middle of the growth period and their nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), manganese (Mn), zinc (Zn), and boron (B) contents were determined. Present findings revealed that transition from flood irrigation to drip irrigation did not result in any nutritional problems. On the other hand, significant increases were observed in contrary, the uptake of P, Fe, Mn, Zn, and B uptake of the plants.
