“…(Simsek et at 2011) revealed that, as the moisture deficit level increased the production of crops will be declined which agreed with the current findings. Other reports conducted on soybean by Robel Admasu and Addisu Assefa (2019), Meskelu and Tesfaye (2018) and Mohammed and Kannan, (2015) on maize crop discovered that above-ground dry biomass yield is higher for conventional furrow irrigation system than alternate and fixed furrow irrigation methods which support our current findings.…”

Irrigation water availability is diminishing in many areas of the Ethiopian regions, which require many irrigators to consider deficit-irrigation strategy. This study investigated the response of maize (Zea mays L.) to moisture deficit under conventional, alternate and fixed furrow irrigation systems combined with three irrigation amounts over a two years period. The field experiment was conducted at Selekleka Agricultural Research Farm of Shire-Maitsebri Agricultural Research Center. A randomized complete block design (RCBD) with three replications was used. Irrigation depth was monitored using a calibrated 2-inch throat Parshall flume. The effects of the treatments were evaluated in terms of grain yield, dry above-ground biomass, plant height, cob length and water use efficiency. The two years combined result indicated that net irrigation water applied in alternate furrow irrigation with full amount irrigation depth (100% ETc AFI) treatments was half (3773.5 m 3 /ha) than that of applied to the conventional furrow with full irrigation amount (CFI with 100% ETc) treatments (7546.9 m 3 /ha). Despite the very significant reduction in irrigation water used with alternate furrow irrigation (AFI), there was insignificant grain yield reduction in maize(8.31%) as compared to control treatment (CFI with100% ETc). In addition, we also obtained significantly (p<0.001) higher crop water use efficiency of 1.889 kg/m 3 in alternate furrow irrigation (AFI), than that was obtained as 0.988 kg/m 3 in conventional furrow irrigation (CFI). In view of the results, alternate furrow irrigation method (AFI) is taken as promising for conservation of water (3773.5 m 3 /ha), time (23:22'50" hours/ha), labor (217.36 USD/ha) and fuel (303.79 USD/ha) for users diverting water from the source to their fields using pump without significant trade-off in yield.Ethiopia comprises of 112 million hectares (M ha) land area. Cultivable land area estimates between 30 to 70 M ha. Currently, an estimate of about 15 M ha of land is under cultivation. For existing cultivated areas, only about 4-5 percent is irrigated; with existing equipped irrigation schemes covering about 640,000 hectares. These irrigation schemes vary widely in size and structure, from micro-irrigation scale (rainwater harvesting) to large scale ( river diversion, pumping and small or large dams) (Awulachew et

“…On the other hand, in the alternate and fixed furrow irrigation systems, not all crop rows get water in each irrigation event, which might lead to an effect agronomy of maize as moisture stress affect photosynthesis. Earlier workers also reported that maximum plant height was recorded in conventional furrow irrigation systems followed by alternate and fixed furrow irrigation systems [ 4 , 21 , 22 ].…”

“…A recent innovative approach to save agricultural water is deficit irrigation. Deficit irrigation provides a means of reducing water consumption while minimizing adverse effects on yield (Mermoud et al, 2005). Deficit irrigation consists of finding the optimum balance between water use and crop yield.…”

Irrigation water supplies are decreasing in many areas of the Ethiopian regions, which is requiring many farmers to consider deficit-irrigating soybean (Glycine max L.). This study investigated the response of soybean (Glycine max L.) to moisture deficit under conventional, alternate and fixed furrow irrigation system over a three years period. A field experiment was conducted at Jimma Agricultural Research. A randomized complete block design (RCBD) with three replications was used. nine treatments which combined and imposed at all growth stages were used. The three years combined result indicated that there were a highly significant (P<0.01) variation among treatments for grain yield, above ground dry biomass yield and water productivity. The grain yield of soybean was significantly (P<0.01) affected due to moisture stress imposed at different growth stages. Accordingly, the highest grain yield was obtained from conventional furrow 100% ETc irrigating all growth stage treatment followed by conventional furrow 75% ETc and alternate furrow 100% ETc. The highest water productivity of 1.23 kg m-3 was obtained from alternate irrigation system at 50 ETc but the yield loss is not tolerable. Alternate furrow 100% ETc and conventional furrow 50% ETc gave a better yield with high water productivity. Therefore, for better water productivity without a significant yield loss, it is recommended to use alternate furrow irrigation with 100% ETc and conventional furrow irrigation 50% ETc. In addition, if the water resource is not scarce in the area, it is recommended to use conventional furrow irrigation with 100% ETc throughout the whole growth stage to obtain optimum yield.
