Irrigation Scheduling of Apple with IRSIS Computer Software in Isparta Conditions

The aim of the study is to obtain irrigation programs of apple for different soil and rain conditions by using IRSIS computer software in sufficient and limited water conditions. First, optimum irrigation program were determined for all soil and rain conditions in sufficient water condition. Then, limited irrigation water amount were determined considering %80, %60 and %40 of which and irrigation water amount calculated in dry year conditions. According to irrigation program for optimum conditions, at heavy soils, irrigation water amount were determined 612.6 mm, 754.5 mm and 917.3 mm for rainy, normal and dry year respectively. At medium texture soils, these values were determined 537.4 mm, 752.3 mm and 864.2 mm and at light texture soils were also determined 562.1 mm, 701.3 mm and 903.8 mm.
