Abstract
Et/Eo values of Panicum miliaceum grown after sugarcane, mustard and wheat and given 0-60 kg N/ha increased progressively with increasing N rates, while the water use efficiency increased with only up to 45 kg N/ha. Total consumptive use of water (CUW) was highest in crops grown after wheat, intermediate in those after mustard and lowest in those grown after sugarcane. Of the total water use, c. 90% soil moisture was extracted from the top 60 cm soil layer. N rates had no effect on pattern of soil moisture extraction from different soil layers. Irrigation scheduled at 70% available soil moisture (ASM) increased the values of CUW, Et/Eo ratio and soil moisture extraction from the upper soil layers and decreased the water use efficiency in all cropping sequences, compared with irrigation at 40% ASM. The water use efficiency was highest in crops grown after sugarcane
