Abstract/ Executive Summary:

This experiment was conducted to determine water requirement for optimum yield and water productivity of BINA developed two rice varieties Binadhan-8 and Binadhan-10, at BINA farm Mymensingh, during January-May, 2013. The seedlings of rice were transplanted on 20 February 2013 (with 65 days old seedling). The design was RCBD (with split-plot). The individual main and sub-plot sizes were 7 m × 5 m and 5 m × 3.5 m, respectively and the treatments were replicated thrice. Main-plot treatments [Irrigation (AWD methods)] were: T₀ = Normal farmer’s practice (continuous ponding, 3-5 cm); T₁ = alternate wetting (irrigation by 5 cm) and drying (AWD) at 3 days after disappearance of ponded water; T₂ = alternate wetting and drying (AWD) at 5 days after disappearance of ponded water (DAD); T₃: 1^st week (after transplanting): 2 - 4 cm ponding, 2-3 week: Irrigation (by 5 cm) at 2 DAD, 3-4 week (up to tillering): Irrigation (by 5 cm) at 3 DAD, 4-6 week(tillering to pre-heading)): Irrigation (by 5 cm) at 5 DAD, 6-9 week (heading – milking): Irrigation (by 5 cm) at 2 DAD, 9-11 week (soft dough – ripening): drying (no additional irrigation). Sub-plot treatments [Variety] were: V₁= Binadhan-8, V₂ = Binadhan-10. Up to three weeks from transplanting, continuous ponding was maintained for crop establishment. Irrigation treatments were then imposed. The results revealed that AWD method had no significant effect on the yield and yield attributing characters, except 1000 seed weight. The highest grain yield (4.90 t/ha) was obtained in continuous ponding method (T₀). The variety V₁ performed better compared to V₂. Treatment T₀ required the highest irrigation water (91.90 cm) and T₂ the lowest (64.90 cm). It is observed that 5 days AWD irrigation method (T₂) saved about 42% irrigation water compared to continuous ponding method, but without compromising yield; and consequently water productivity was also highest

Program Area: Crop-Soil-Water Management

Commodity: Rice

Objectives:

To determine water requirement for optimum yield and water productivity of BINA developed two rice varieties Binadhan-8 and Binadhan-10,

Methodology:

The design was RCBD (with split-plot). Main-plot treatments [Irrigation (AWD methods)] were: T₀ = Normal farmer’s practice (continuous ponding, 3-5 cm); T₁ = alternate wetting (irrigation by 5 cm) and drying (AWD) at 3 days after disappearance of ponded water; T₂ = alternate wetting and drying (AWD) at 5 days after disappearance of ponded water (DAD); T₃: 1^st week (after transplanting): 2 - 4 cm ponding, 2-3 week: Irrigation (by 5 cm) at 2 DAD, 3-4 week (up to tillering): Irrigation (by 5 cm) at 3 DAD, 4-6 week(tillering to pre-heading)): Irrigation (by 5 cm) at 5 DAD, 6-9 week (heading – milking): Irrigation (by 5 cm) at 2 DAD, 9-11 week (soft dough – ripening): drying (no additional irrigation). Sub-plot treatments [Variety] were: V₁= Binadhan-8, V₂ = Binadhan-10.The seedlings of rice were transplanted on 20 February 2013 (with 65 days old seedling). The individual main and sub-plot sizes were 7 m × 5 m and 5 m × 3.5 m, respectively and the treatments were replicated thrice. Up to three weeks from transplanting, continuous ponding was maintained for crop establishment. Irrigation treatments were then imposed. Measured amount of water applied in each plot through water-meter, attached at the outlet point of rubber hose pipe. All cultural practices were followed as and when necessary. The crop was harvested on 20 May (89 days at field). The grain and straw yields were adjusted to 12% moisture content.
