To decree evapotranspiration from soil surface and improving irrigation efficiency and reduce water usage in cotton cultivation , plastic mulch was applied in furrow irrigation. This study was performed as a split plot experiment in capability randomized complete block design, in 3 replications. The experiment was located in Khorasan Razavi –Kashmar- Kashmar agricultural research station and was applied in 2 years, 2004-2005. The treatments were consist of irrigation period at three levels ; 6, 9 and 12 days as main plot and plastic mulch at three levels I-black plastic mulch, II- white plastic mulch and III- control (without plastic mulch)as a subplot on furrow irrigation. Each treatment was irrigated up to field capacity. The results showed that application of plastic mulch used better water usage and black plastic mulch was more effective. Meanwhile The results showed that the use of plastic mulch had significant effect on reducing of weed growth, plant height increasing, yield and water use efficiency in respect with control.
