The water saving technology for lowland rice cultivation was very crucial because of in the future irrigation water become scarce and competed with other sectors. The lowering of the availability of irrigation water had the impact for sustainability of rice production. The study revealed that treatment I₁ attributed by the highest total water use (1646 mm) and the lowest Water productivity (0.46 kg m⁻³) produced the highest grain yield (7.56 t/ha). Treatment I₅ and I₆, on the contrary, gave the second highest yield (7.21 and 7.05 t/ha) and consequently the second highest water productivity (0.65 and 0.59 kgm⁻³) indicating quite a large water saving (26.6 and 35%) compared to treatment I₁. The yields in treatments I₄ (6.0 t/ha) and I₈ (6.30 t/ha) were significantly lower at 5% level of significance compared to that of treatment I₁. No significant effect was found for the AWD irrigation regimes on the post-harvest soil nutrient status. Reduced plant height, leaf area index, plant nutrient uptake, grain yield, straw yield and harvest index were found with the increasing water stress. The study emphasized that rice crop can be successfully grown by adopting an appropriate AWD irrigation regime without any significant yield decline under sandy clay soils.

低地水稻种植的节水技术非常重要，因为未来灌溉用水将变得稀缺并与其他部门竞争。灌溉用水的减少影响了水稻生产的可持续性。研究表明，总用水量最高（1646 mm）和水生产率最低（0.46 kg m ^{-3 ）的处理 I} ₁产生了最高的粮食产量（7.56 t/ha）。相反，处理 I ₅和 I _{6产量第二高（7.21 和 7.05 t/ha），因此水生产率第二高（0.65 和 0.59 kgm} ^-3），表明节水量相当大（26.6 和 35%） ) 与治疗 I _1相比。_{与处理I 1}相比，处理I ₄ (6.0 t/ha)和I ₈ (6.30 t/ha)的产量在5%显着水平上显着降低。没有发现 AWD 灌溉方式对收获后土壤养分状况有显着影响。随着水分胁迫的增加，株高、叶面积指数、植物养分吸收、籽粒产量、秸秆产量和收获指数降低。该研究强调，通过采用适当的全轮驱动灌溉方式，水稻作物可以在沙粘土下成功生长，而不会出现任何明显的产量下降。
