Abstract

AbstractThis study was conducted in Al-Hawija district-Kirkuk Governorate to eva- luate response of five Cotton genotypes (Lachata, Coker 310, Coker 5114, Dunn 1047 and SP 8886) for irrigated water quality (wastewater and fresh water) by using RCBD design in split plot with three replicates, the main plots represented by a water quality while the genotypes occupied the sub plots. The studied traits were: No. of days to first open flower, No. of monopodial branches/plant, No. of Sympodial branches/plant, plant height, No. of opening bolls/plant, boll weight, earliness index, lint percentage and seed cotton yield.The results showed that wastewater irrigated treatment was significantly superior in all studied traits except No. of days to first open flower and No. of monopodial branches/plant. There were a significant differences among genotypes for all studied traits, Dunn 1047 genotype significantly superior in traits: boll weight, earliness index, and seed cotton yield. There was a significantly interaction between water quality and genotypes in traits: No. of days to first open flower and plant height only. This study illustrate that cotton crop possibility cultivate with wastewater irrigation because there wasn't any negative effective for wastewater on all studied traits.
