摘要

Field experiments were conducted to determine the optimal range of bed width under the bed and furrow irrigation technique of wheat at Koga (clay soil) and Rib (loam soil) irrigation scheme, North West Amhara, Ethiopia during 2016/17 and 17/18 irrigation seasons. The experiment was arranged in a randomized complete block design having seven treatments of (40, 60, 80, 100, 120, 140 and 160 cm) bed width and the recommended water depth for each treatment and each site were measured and applied through Parshall flume. It was found that bed width on a raised bed in different soil texture had significantly affected yield and water productivity of wheat. The result indicated that 60 cm to 80 cm bed width at Koga showed up to 26% yield advantage and saves about 25% irrigation water as compared to farmer practice. Similarly, Plant height has statically difference with farmer practice but the panicle length of wheat has no significant difference between the normal irrigation practice and the optimal bed width. Moreover, using 100 cm to 140 cm bed width at Rib (loamy soil) has up to 27% yield advantage and saves 28% irrigation water as compared to farmer practice. The plant height showed a statically significant difference but the panicle length of wheat has no significant difference between the farmer irrigation practice and the optimum bed width. Therefore, we concluded that the cultivation method under different soil texture and raised bed width affect yield and water productivity of wheat.
