A study was conducted to generate information about the optimum timing of irrigation and the quantity of water required for a good yield of wheat. The study was conducted during the rabi season of 2000-2001 and 2001-2002 at the Wheat Research Centre, Nashipur, Dinajpur. Irrigation water was applied by different amounts and at different growth stages of the crop. In the first year, treatment T7, receiving 4 irrigations and 170 mm water, produced the highest yield (4.17 t/ha) but of wheat. From two years results, it was observed that four irrigations with 170-180 mm water produced good yields (4.17 t/ha to 4.24 t/ha) of wheat in Dinajpur region.

This study was undertaken to generate information about the optimum timing of irrigation and the quantity of irrigation water required for wheat in Dinajpur region.
The experiment was conducted at the Wheat Research Centre, Nashipur, Dinajpur during the rabi seasons of 2000-2001 and 2001-2002. The experiment was laid out in a randomized complete block design with three replications and seven treatments. Fertilizers at the rate of 100, 60, 40 and 20 kg/ha of N, P2O5, K2O and S were applied to all the treatments. Seeds were sown on 29 November 2000 and 07 December 2001 by power operated tiller cum seeder (POTS), which is a multipurpose equipment (three in one) that does tilling, sowing and compacting soil around the seeds, simultaneously. Measured quantity of water was applied to all the treatments using hose pipe connected to a graduated tank. The treatments were:
T1= 30 mm (17-21 DAS)
T2= 30 mm (17-21 DAS), 60 mm (50-55 DAS)
T3= 30 mm (17-21 DAS), 40 mm (50-55 DAS), 50 mm (75-80 DAS)
T4= 30 mm (17-21 DAS), 50 mm (50-55 DAS), 60 mm (75-80 DAS)
T5= 30 mm (17-21 DAS), 60 mm (50-55 DAS), 70 mm (75-80 DAS)
T6= 30 mm (17-21 DAS), 40 mm (50-55 DAS), 40 mm (60-65 DAS), 30 mm (80-85 DAS)
T7= 30 mm (17-21 DAS), 50 mm (40-45 DAS), 50 mm (60-65 DAS), 40 mm (80-85 DA

From two years study, it was observed that both number of irrigation and quantity of water were important in the variations of yield of wheat. Further, excess or deficit water reduced crop yields substantially. Thus, four irrigations amounting to 170 to 180 mm water can be applied to obtain 4.17 to 4,24 t/ha of yield of wheat in Dinajpur region.
