Field experiments were carried out during winter seasons of 1987-1988 and 1988-1989 at the Indian Institute of Horticultural Research, Bangalore, to study the effect of irrigation levels and N fertilization rates on growth, yield, N uptake, and water use of carrot. Frequent irrigations with 100% replenishment of evaporation losses resulted in highest root yield, total dry matter, leaf area index, N uptake, and water use efficiency. Maximum root yields and water use efficiency were recorded with 120 kg N/ha. Interaction effect indicated highest yields with 100% evaporation replenishment and 120 kg N/ha (35 t/ha).
