AI InsightThe results revealed that cotton can be irrigated with drip systems using a 10 day interval, Kcp 0.90 or 1.05 (mean: 1.00) and P based on the actual cover percentage of the crop.

This study was conducted to determine the amount of irrigation water and interval of cotton irrigated by the drip system with the pan-evaporation method. The amount of irrigation water applied was based on free surface evaporation from a screened Class-A Pan. Irrigation treatments consisted of two different irrigation intervals (I1: 5; I2: 10 days), and three plant-pan coefficients (Kcp1: 0.75, Kcp2: 0.90, Kcp3: 1.05) and two different wetted percentages (P1: 0.70 and P2: based on the cover percentage of the crop). According to the results, seasonal irrigation water varied from 322 to 472 mm; seasonal Et was 449 to 615 mm; and the cotton yield varied from 1970 to 4220 kg per hectare. Although the effect of irrigation intervals and wetting percentages on cotton yield were not significantly different, plant-pan cofficients in the first year and P-Kcp interaction in the second year were significantly different at a 5 % level among the treatments. The results revealed that cotton can be irrigated with drip systems using a 10 day interval, Kcp 0.90 or 1.05 (mean: 1.00) and P based on the actual cover percentage of the crop.
