Irrigation Water Management of Some Salt Tolerant Rice Cultivars for Higher Yield
Journal Title: Asian Journal of Advances in Agricultural Research - Year 2017, Vol 3, Issue 4
Abstract
Salt stress is one of the most important abiotic stresses that adversely affect crop productivity and causes significant crop loss worldwide. The objective of this field study was to investigate the effect of different irrigation regimes and ameliorative on the yield performance of some rice lines/cultivars in salt affected area of Bangladesh. Irrigation treatments were comprised of: continuous saturation + gypsum application at flowering stage (T1); continuous ponding with 2 cm + gypsum application at flowering stage (T2); continuous ponding with 5 cm + gypsum application at flowering stage (T3); AWD lowering with 5cm (T4); AWD lowering with 10 cm (T5). The lines/varieties tested were: V1= RC-222, V2= RC-228, V3= Binadhan-8, and V4= Binadhan-10. The interaction results revealed significant effect on yield attributing characters as well as on grain yield. The highest grain yield (5.83 t/ha) was observed in continuous ponding by 2 cm coupled with gypsum at flowering stage, followed by continuous saturation condition plus gypsum, with Binadhan-8. Considering the grain yield and irrigation water used, Binadhan-8 can be cultivated under continuous saturation condition couple with gypsum application at flowering stage.
