Abstract
Determination of Irrigation Scheduling of Drip Irrigated Tomato Using Pan- Evaporation in Harran Plain
This study was conducted to determine the amount of irrigation water and two irrigation intervals on the yield and growth of tomato irrigated by drip method. The amount of irrigation water applied was based on cumulative evaporation from a screened class-A pan. The irrigation treatments consisted of two different irrigation intervals (I] = 4 and I2 = 8 days), and three pan coefficients (kcpi= 1.00, kcp2 = 0.80, kcp3= 0.60). The seasonal irrigation water varied from 465 to 920 mm; the seasonal ET ranged from 495 to 1150 mm; and yield of tomato varied fiom 53.1 to 112.5 ton ha" based on treatments used. According to the results, it was concluded that tomato could be irrigated at 4-day irrigation intervals and the irrigation water amount might be computed by 0.80 of class-A-pan cumulative evaporation.
