A field experiment was conducted in Rudrur, Nizamabad district, Andhra Pradesh, India, during 2000-01 and 2001-02 to study the effects of the absence of irrigation during summer (I0), drought management practices or I1 (trash mulching at 30 DAP [days after planting] + spraying of urea and KCl at 2.5% every month + application of potash as 50% basal and 50% dressing before summer), and irrigation monthly during summer (I2), on sugarcane yield, and to evaluate the performance of 5 sugarcane clones (Co 8014, 92R 247, 93R 217, 93R 244 and 92R 62) under drought stress during the formative stage. I1 increased the cane yield by 10.33% and the sucrose content by 5.73% over I0. Greater tiller production was also obtained under I1 (102 380/ha, on average) than under I0 (95 050/ha). 93R 244 and 92R 247 were the most responsive to drought management practices, and can be recommended for cultivation in drought-prone areas. Relative to I0, the yields of 93R 244 and 92R 247 increased by 13.41 and 13.38%, respectively, under I1.
