Abstract

With population growing throughout the world, it is necessary to optimize water use especially in agriculture land. In order to investigate the determination of WATER USE EFFICIENCY of Cotton using MICRO IRRIGATION system, a field experiment was conducted in Agricultural and Natural Resource Research Institute of ORZOUEYEH, Kerman province. The experiment was conducted in split plot design based on Randomized Complete Block Design (RCBD) with three replications. The treatments were comprised of three levels of crop water requirements (i.e. I1: irrigation based on 125 percent water requirement, I2: irrigation based on 100 percent water requirement, and I3: irrigation based on 75 percent water requirement, in main plot and two tape position patterns as sub plot consisted of conventional (r1) and alternative (r2). All treatments were assessed for productivity, water use and its efficiency, and economical issues as well. The results showed that the yield resulted from I1 was 379 and 1204 kg/ha higher than that of I2 and I3, respectively. In addition, the obtained yield due to r1 system was 377 kg/ha greater than the r2 pattern. Also interaction of treatments on crop yield indicates that the I1r1 treatment has the maximum yield. Despite of use water equality in sub plots, the WUE in r1 was 16 percent higher than r2. However, economical assessment exhibited that system cost in the r2 in comparison with the r1 was 11 percent lower.
