ABSTRACTwas also significantly higher than that from NTJ 2 (US$ 415 ha -1 ) and ICSV 93046 (US$ 539 ha -1 ). All cultivars responded to applied N up to 150 kg ha -1 ; however beyond 90 kg ha -1 N rate, the increase in yield was insignificant. Estimated N use efficiency (NUE) values indicated that 90 kg N ha -1 was an optimum N level for sweet sorghum crop. Simulated soil water balance components revealed that reduction in total transpiration due to water stress was 20 to 45% compared to the no-stress. In case of water use efficiency, CSH 22 SS showed the highest economic returns per unit volume of water input. Based on these results, it is concluded that sweet sorghum hybrid CSH 22 SS at 90 kg N ha -1 is the best remunerative combination for maximizing yield, economic returns and resource use efficiency.
