The Soybean Growth and Yield with Different Water Depths and Bed Widths on Mineral Soil
Keywords:Glycine max (L.) Merr., irrigation, overflow, pyrites
AbstractOne of marginal lands in Indonesia is acid sulphate soil, which is potential for agriculture. Saturated soil culture is one of cultivation technologies that suitable on acid sulphate soil, because itÂ can prevent pyrites oxidation and maintains soil moisture during plant growth. This research aimed to study the effect of water depth and bed width under saturated soil culture on soybean growth. The experiment was held on mineral soil type in South Sumatera Province, Indonesia from April-September 2014. The experiment was arranged in Split-plot design with three replications. The main plot of the experiment was water depths consisted of 10 and 20 cm below soil surface. The sub plot of the experiment was bed widths consisted of 2, 4, 6, and 8 m. The bed width of 4 m as same as 8 m and 20 cm water depth below soil surface gave the highest yield on mineral soil.
