This study aimed to evaluate the effect of sowing date, cultivar and method of sowing on the yield of some quantitative and qualitative traits of cotton in subtropical climates of Orzouieh Kerman- Iran (with cotton-maize-sesame-wheat-barley cropping system). Field experiments were carried out in 2017 and 2018. Experiments were conducted as split-split plots based on a randomized complete block design with three replications. Treatments were included: A) Sowing date in three levels:1- May 22 (plant transfer: 1 month ago), 2- June 10 (transplanting: 1 month ago) and 3- July 1 (plant transfer: 1 month ago) as the main plots, B) Cultivar: 1- Khordad 2-Varamin 3-hybrid (as subplot), C) Method of cultivation in three levels: 1- single plant cultivation, 2- double plant cultivation and 3- seed cultivation as the subplot. The results showed that quantitative parameters such as yield (kg ha-1), cotton yield (kg ha-1), fibre yield (kg ha-1), and water use efficiency (kg m-3) as well as qualitative parameters such as fibre length (mm), fibre strength (g/tex) and fibre thickness (Micronaire) it had significant differences with transplanting of Khordad cultivar on May 22 compared to direct seed planting on May 22. The sowing date of June 10 and July 1 in all three cultivars and sowing methods had the lowest yield at the same planting date. These results showed that in the cotton-maize-sesame-wheat-barley cropping system in the subtropical zone of Orzouieh region -Kerman-Iran, transplanting of Khordad cultivar compared to seed direct sowing in the May 22 date is a suitable strategy to improve the qualitative and quantitative yield of cotton.
