Analysis of Crop Water Requirements for Apple Using Dependable Rainfall

Rainfall expected to occur in a given period is defined as dependable rainfall. The increasing pressure on freshwater resources necessitates efficient water use the agricultural sector, where used most globally. Therefore, rainfall values dry (80%), normal (50%) and wet (20%) periods, which are planning operation stages of irrigation networks, can be determined by analysis. In this study, change requirement apple trees was investigated based Warsaw Isparta, two important production regions Poland Turkey. For purpose, both locations between 1984 2021 were calculated monthly annually with Rainbow program. Then, using climate parameters relevant years, plant consumption requirements help Cropwat software. As result research, dry, rainy years 466 mm, 532 mm 604 respectively, while, these 422 520 602 respectively. Crop 363 237 108 during while 452 367 277 Isparta. application appropriate rates that take into account will optimize also improve yields. This extremely for research areas particular, Turkey among largest producers world.
