Irrigation scheduling based on pan evaporation values for cucumber (Cucumis sativus L.) grown under field conditions

This study was conducted to determine the most suitable irrigation frequency and quantity in cucumber grown under field conditions. The amount of water used was based on pan evaporation from a screened Class-A pan. Irrigation treatments consisted of two irrigation intervals (I1: 4 and I2: 8 day), and three plant-pan coefficients (Kcp1: 0.50; Kcp2: 0.75 and Kcp3: 1.00). Plants were first watered at the transplanting date and scheduled irrigations were initiated after 4- and 8-day intervals.
