A field experiment was conducted at the Bangladesh Rice Research Institute, Shampur, Rajshahi to find out possible effects of alternate wetting and drying irrigation (AWDI) on the yield, water use and water use efficiency (WUE) of rice. The experimental plots were laid out with 2 factors RCBD combining two modern varieties of rice viz. BRRI dhan28 and BRRI hybrid2, which received four irrigation treatments randomly and was replicated thrice. The treatments ranged from continuous submergence (T1) of the field to a number of delayed irrigations (T2, T3 and T4) denoting application of 3, 5 and 7 days of disappearance of standing water respectively. The study revealed that treatment T1 attributed by the highest total water use (49.04 cm) and the lowest WUE (60.62 kg/ha/cm) produced the lowest grain yield (4.59 t/ha). Treatment T2, on the contrary, gave the highest yield (5.57 t/ha) and consequently the higher WUE (85.55 kg/ha/cm) than T1 and indicating quite a large water saving (Application of 3 days of disappearance of Standing Water) compared to treatment T1. The yields in treatments T3 (5.33 t/ha) and T4 (5.15 t/ha) were significantly lower at 1% level of significance compared to that of treatment T1. Significant effect was found either for the treatment or for the varieties on the number of effective and total tillers hill-1 1000 grain weight, plant height, number of effective tillers hill-1, grain yield, straw yield, biological yield and harvest index.
