Özet
The aim of this study was to estimate the evapotranspiration of cauliflower and red cabbage crops grown under cool season semiarid climatic conditions from Class A pan evaporation. Actual evapotranspiration (ETc) of cauliflower and red cabbage crops was calculated according to the water balance approach. Reference evapotranspiration (ETo) was calculated with FAO Penman-Monteith equation. Pan evaporation (E-pan) was measured by using Class A pan. Seasonal ETc was determined as 475 mm for cauliflower and 556 mm for red cabbage. Seasonal pan coefficient (k(p)=ETo/E-pan) was determined as 0.82, and the seasonal crop coefficient (k(c)=ETc/ETo) was determined as 0.84 for cauliflower and 0.83 for red cabbage. So the evapotranspiration of cauliflower and red cabbage crops was estimated as 70% Class A pan evaporation.
