Field studies were done in 2003 and 2006 to evaluate the performance of water pillow (WP) irrigation as an alternative to furrow irrigation (FI) for soybean growth in semi-arid climatic conditions. There were four irrigation treatments: two of which (FI and WP₁.₀) were full irrigation, in that the water deficit in the soil profile (0.9m) was brought to field capacity in 10-day intervals. The other two treatments (WP₀.₇₅ and WP₀.₅₀) were deficit irrigation treatments, and received 75% and 50% of WP₁.₀ irrigation amount. The highest seed yield was achieved with the WP₁.₀ treatment. Irrigation water use efficiency (IWUE) and water use efficiency (WUE) were influenced significantly by the irrigation methods and levels (P <=0.05). The highest values of WUE and IWUE were obtained by the WP₀.₇₅ and WP₀.₅₀ treatment, respectively, in both study years. However, the smallest irrigation amount resulted in lower total yield for the WP₀.₅₀ treatment, and is not recommended. In conclusion, the WP₀.₇₅ treatment is recommended for soybean production in order to attain higher values of IWUE and WUE, and to conserve water and maximize yield with the same volume of water.
