Özet
This study aimed to investigate response of "Granny Smith" apple (Malus domestica Borkh.) tree to irrigation under farmer condition in Duzce Region. In this study, some physiological measurements, such as leaf water potential (LWP), stomatal conductance (g(s)) and photosynthetic active radiation (PAR) on the apple trees, were performed weekly before irrigation in the selected period during the irrigation season. Concurrently, in irrigation season, soil water content (SWC) in the different soil layers (0-30 cm, 30-60 cm, 60-90 cm, and 90-120 cm) was also monitored at the apple orchard. Study results showed that SWC was fluctuated between field capacity (FC) and permanent wilting point (PWP) during irrigation season. The value of SWC didn't reach up to 50%, which is the allowable depletion value at the soil of apple orchard, except some high rainy days. LWP, gs and PAR were increased by increasing of SWC in all soil layers. The strongest relationship for all correlations in all soil layers was obtained in 30-60 cm soil layers. It was found that LWP had strong relationships with PAR (R-2=0.84) while LWP(similar to)g(s) relationships were weak (R-2=0.53). Finally, by considering the all results in this study, it may be concluded that a proper irrigation scheduling was needed for such as apple orchards even though precipitation was frequently and unevenly happened in the summer.
