Abstract :This study was conducted to determine of effects the cotton plant growth of different irrigation programs in a drip system. The amount of water applied was based on free surface evaporation from a screened Class-A Pan. Irrigation treatments consisted of two different irrigation intervals insert ignore into journalissuearticles values(I1: 5; I2: 10 days);, and three plant-pan coefficients insert ignore into journalissuearticles values(Kcp1: 0.75; Kcp2: 0.90 and Kcp3: 1.05); and two different wetted percentages insert ignore into journalissuearticles values(P1: 0.70 and P2: based on cover percentage of the crop);. The first irrigation was applied when the available soil moisture in the 120 cm depth in the profile was at 40%. According to the results of the experiment, significant relationships between plant height, leaf area index insert ignore into journalissuearticles values(LAI);, development of plant cover, and dry matter both with irrigation water and evapotranspiration were determined.
