Nine Egyptian cotton cultivars (G. barbadense L.) were evaluated for earliness, yield and yield components for two successive seasons at two contrasting environments; Assiut Univ. Exper. Farm (clay soil) and Desert Agric. Exper. Sm. at Wady EI-Assiuty (sandy soil, drip irrigation). Three irrigation treatments; 80, 100 and 120% evapotranspirtaion (Et) were used. The performance of the nine cultivars for yield and its attributes except lint percentage was very low at sandy soil compared to clay soil. The effect of irrigation treatments was highly significant at both locations. The highest level of irrigation (120% Et) was the best for all yield traits. In addition, it increased days to first flower and decreased earliness index. The interaction of irrigation x cultivars was highly significant for all traits except for lint %, seed and lint indices at both locations and boll weight at the sandy soil. Dandara and Giza 83 were the best cultivars for all traits. Furthermore, they were the earliest cultivars. Drought susceptibility index indicated that Dandara and Giza 83 were tolerant to drought for seed cotton and lint yields/plant, number of bolls/plant and boll weight. The other cultivars could be considered susceptible to drought.
