The aim of present study is evaluation of the effect of four rates of superabsorbent polymer (0, 75, 150 and 225 kg ha(-1)) and three irrigation intervals (6, 8 and 10 days) on growth and yield of soybean (cult. L11) under field conditions. The results of this study showed that there was a significant effect among irrigation intervals on seed yield, Total Dry Matter (TDM), Leaf Area Index (LAI), Crop Growth Rate (CGR), plant height and Harvest Index (HI). Moreover, The highest increase in seed yield, Total Dry Matter (TDM), Leaf Area Index (LAI), Crop Growth Rate (CGR) and Harvest Index (HI) were achieved at 225 kg ha(-1) polymer compared with the control (without polymer). These results indicate that application of superabsorbent polymer at 225 kg ha(-1) appeared to increase all the above growth and yield attributes.
本研究的目的是评估四种超吸水性聚合物施用量（0、75、150和225千克/公顷）以及三种灌溉间隔（6、8和10天）对田间条件下大豆（L11品种）生长和产量的影响。本研究结果表明，灌溉间隔对种子产量、总干物质（TDM）、叶面积指数（LAI）、作物生长速率（CGR）、株高和收获指数（HI）有显著影响。此外，与对照（不施用聚合物）相比，施用225千克/公顷聚合物时种子产量、总干物质（TDM）、叶面积指数（LAI）、作物生长速率（CGR）和收获指数（HI）的增幅最大。这些结果表明，施用225千克/公顷的超吸水性聚合物似乎能提高上述所有生长和产量指标。
