This study was conducted in order to determine effect of water requirement, irrigation treatments and water use efficiency of capsicum crop. Experiments were carried out in the College of Agricultural Engineering, Madakasira between January to May 2018, with cv. Indra. The maximum yield of 4.3 t ha-1 was obtained from treatment 1(1.0 ETc). The seasonal irrigation water amount of treatment was 562.5 mm determined by AquaCrop 6.0 model. Capsicum yield of 3.8 t ha-1 was obtained under treatment 2 (0.75 ETC) of 421.87 mm seasonal irrigation water requirement and under treatment 3 (0.5 ETC) 2.1 t ha-1 with the seasonal irrigation water amount of 281.25 mm. Although water saving of 140.63 mm in treatment 2 and 281.25 mm in treatment 3. The method of determination of water requirement is AquaCrop 6.0 model. Predicted water requirement through AquaCrop is compared with the pan evaporation data. From this experiment AquaCrop model appeared to be most reasonable and effective one in terms of yield and WUE. On the other hand, the maximum irrigation water use efficiency 9.19 kg ha-1mm-1 in treatment 2 followed by treatment 1 and treatment 3.
