Field experiment was conducted at the Bangladesh Agricultural University (BAU) farm during Rabi season (from 25 November 2011 to 24 March 2012) to investigate the effects of irrigation water and variety on wheat production. The experiment was set up using split plot design (SPD) with two modern-varieties (MV) of wheat BARI Gam-25 (V1) and BARI Gam-26 (V2), each of which received four irrigation treatments viz., T1 (control), T2 ((17-21 Days After Sowing (DAS)), T3 (17-21) + (45-50) DAS) and T4 ((17-21) + (45-50) + (75-80) DAS), that were randomly replicated thrice. Irrigation was applied IW (Irrigation water) and CEP (Cumulative Pan Evaporation) ratio. The study revealed that maximum grain yield was found BARI Gam-25 which was 4.11 t ha-1 where BARI Gam-26 produced 3.90 t ha-1 and the highest grain yield (4.32 t ha-1) was found in treatment T4, its water productivity was the lowest (289 kg ha-1cm-1) of all. On the contrary, treatment T3, gave a yield of 4.25 t ha-1 which was highest one having the highest water productivity of 346 kg ha-1cm-1, indicating less use of water. The grain yield in treatments T1 and treatment T2 produced 3.47 t ha-1 and 3.99 t ha-1 respectively which were significantly lower as compared to T3 and T4. The highest irrigation requirement (7.78 cm) was found in the treatment T4, while treatment T3 needed only 5.08 cm of water saving about 2.70 cm of water. The effect of variety on plant height and harvest index was significant at 1% level of probability.

Abstract
Field experiment was conducted at the Bangladesh Agricultural University (BAU) farm during Rabi season (from 25 November 2011 to 24 March 2012) to investigate the effects of irrigation water and variety on wheat production. The experiment was set up using split plot design (SPD) with two modern-varieties (MV) of wheat BARI Gam-25 (V1) and BARI Gam-26 (V2), each of which received four irrigation treatments viz., T1 (control), T2 ((17-21 Days After Sowing (DAS)), T3 (17-21) + (45-50) DAS) and T4 ((17-21) + (45-50) + (75-80) DAS), that were randomly replicated thrice. Irrigation was applied IW (Irrigation water) and CEP (Cumulative Pan Evaporation) ratio. The study revealed that maximum grain yield was found BARI Gam-25 which was 4.11 t ha-1 where BARI Gam-26 produced 3.90 t ha-1 and the highest grain yield (4.32 t ha-1) was found in treatment T4, its water productivity was the lowest (289 kg ha-1cm-1) of all. On the contrary, treatment T3, gave a yield of 4.25 t ha-1 which was highest one having the highest water productivity of 346 kg ha-1cm-1, indicating less use of water. The grain yield in treatments T1 and treatment T2 produced 3.47 t ha-1 and 3.99 t ha-1 respectively which were significantly lower as compared to T3 and T4. The highest irrigation requirement (7.78 cm) was found in the treatment T4, while treatment T3 needed only 5.08 cm of water saving about 2.70 cm of water. The effect of variety on plant height and harvest index was significant at 1% level of probability.
