  Irrigation scheduling is the use of water management strategies to prevent over application of water while minimizing yield loss due to water shortage or drought stress. The experiment was performed at Odo shakiso District on farm in the 2020/21 and 2021/22 irrigation seasons, with the objective of determining the optimum irrigation schedule on Yield, yield component and water productivity of Onion based on the available soil moisture depletion levels. The experiment was carried out in RCBD with three replications, randomly assigned to the experimental plots with treatments. Five available soil moisture depletion levels (20% ASMDL, 40% ASMDL, 60% ASMDL, 80% ASMDL and FAO recommended ASMDL) were used as treatment. The results obtained of two years of research showed that different of levels of soil moisture available had a significant effect (P< 0.05) on bulb.. Read More»
