A field experiment in 1976-8 was conducted to study the effect of different soil moisture regimes and N rates on the consumptive use, soil moisture extraction pattern, water use efficiency and yield of sugarbeet. The max. consumptive use values of 60.95 and 56.82 cm were observed at 80% available soil water which resulted in max. sugar yield of 5.9 and 6.7 t/ha during the 1st and 2nd year, resp. In wetter regimes, soil moisture extraction was noticed up to 0-120 cm soil layer, whereas in drier regimes, it was mostly confined to 0-60 cm depth. Water use efficiency was higher under more available moisture and increasing rates of N. Higher rates of N slightly enhanced consumptive use.
