Cauliflower is a reach source of vitamin B and protein and is a main horticultural crop. Its production can be increased by application of irrigation water with required quantity at right time by right method. Irrigation scheduling, considering crop water requirement, plays a vital role in crop production. The microsprinkler irrigation was used for water application to cauliflower and the treatments were based on different microsprinkler spacings i.e. 8m × 8m (T1), 7m × 7m (T2), 6m × 6m (T3), 5m × 5m (T4), 4m × 4m (T5) and 3m × 3m (T6). The water depth applied in T1, T2, T3, T4, T5 and T6 was 17.1, 18.2, 19.9, 22.1, 26.6 and 32.9 cm, respectively. The cauliflower yield obtained in T1, T2, T3, T4, T5 and T6 was 22.82, 23.80, 28.13, 31.70, 29.00 and 26.40 tonne/ha, respectively. The maximum water use efficiency, 1.43 tonne/ha-cm, was recorded in T4. Based on Uniformity Coefficient (UCC), depth of water application ( x ) and actual yield (Y), the production of cauliflower can be predicted as Y = –200.531 + 4.083 x + 0.0081 x 2 {1 +1.570 (1- UCC/100)2}.
