Özet

The purpose of the study has been an attempt at a comparison of pear-tree water needs in the vegetation period in the Bydgoszcz region (Poland) and in the Isparta region (Turkey). The paper refers to the 1984-2014 temperature and rainfall values in the Bydgoszcz and Isparta regions. To determine the reference evapotranspiration (ETo), the calculation model by Hargreaves - modified by Droogers and Allen - was applied. Potential evapotranspiration (ETp), identified with pear-tree water needs, was determined with the method of crop coefficients proposed by Doorenbos and Pruitt. In each of the seven months considered (April-October) higher pear-tree water needs occurred in the Isparta region. The highest monthly pear-tree water needs were noted in July and in the studied period, respectively for the Bydgoszcz and Isparta regions, they were on average 105 mm and 215 mm. Pear-tree water needs throughout the vegetation period (April-October) were much higher (by 114 %) in the Isparta region than in the Bydgoszcz region. The highest rainfall deficits occurred in July and, respectively for the Bydgoszcz and Isparta regions, amounted to 33 mm and 195 mm.
