Abstract/ Executive Summary:

The studies were conducted at Barisal to find out the water requirement and yield obtained from WSR and TPR. Experiments were carried out with 4 water treatments of which T₁ was continuous standing water, T₂ was intermittent irrigation, T₃ as T₁ and 20 days no irrigation at vegetative stage and T₄ as T₁ and 20 days no irrigation at reproductive stage. The treatments T₃ and T₄ could not properly maintained due to rainfall. In Barisal for WSR irrigation water required were 911, 738, 752 and 765 mm under T₁, T₂, T₃ and T₄, respectively and that for TPR irrigation water required were 980, 802, 796 and 775 mm under T₁, T₂, T₃ and T₄, respectively. The higher yield (3905 kg/ha) was obtained from T₂ in WSR but in TPR it was 3225 kg/ha from T₃. The higher water productivity was obtained under T₁ in case of WSR, whereas the same was under T₃ for TPR.
