Abstract

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 }.

Keywords : The order of importance of each parameter was calculated.
