ABSTRACT

This study investigates the effect of drought stress on the yield and the yield components of four cotton genotypes in a field experiment, at the Garmsar region. The experimental design was conducted by randomized block with three replications using factorial concepts. Three levels of drought stress comprising (FC 90%, FC 50%, and FC 20%) were employed as the main factor. Four cotton genotypes including Khordad, Varamin, NO200, KC8801 were selected as sub-factors. The results showed that the effect of stress on all traits were significant and the stress reduced the weight of boll. The biggest bolls were produced by the genotype KC8801. While the genotype NO200 produced the lightest weight of the bolls. The maximum and the minimum values of the cotton yield were observed in the genotypes KC8801 (FC 90%) and NO200 (FC 20%) with the rates of 3322kg/ha and 2160 kg/ha, respectively.
