Abstract

Due to water deficit in Golestan, it is necessary to optimize use of water which means to find relation between water use and yield. For this reason, this experiment was conducted by sprinkler irrigation as line source. Six irrigation treatments as I1, I2, I3, I4, I5 and I6 is assumed in two hand of sprinkler line because of sprinkler water triangular distribution, so that I1 and I6 treatments received the highest and the lowest water, respectively and I2 treatment received as water requirement as. Three cotton cultivars of Sahel, Sepid and 818–312 were planted by 20 × 80 centimeter. Experimental design was strip split plot with three replications. The results showed that the highest yield was I3 treatment that with I4, I5 and I6 treatments in the first year and all treatments in the second year had significant difference. Sepid cultivar yield was 17.9 % higher than two cultivars in the first year and 15 % higher than Sahel cultivar in the second year. Difference between three cultivars on view of earliness was not significant and on view of boll weight in the first year was not significant but in the second years was significant. The highest boll weight belonged to I3 Treatment and also I6 Treatment was the highest earliness. Sahel cultivar during two years had the lowest micronairy. Treatment of I3, received on view of water use received 30% less water than water requirement. Ultimately, on view of yield, quality properties and less water use, the best irrigation treatment and cultivar were I3 treatment and Sepid cultivar.
