Summary

The study aimed to determine the onion crop water requirement (CWR) and irrigation schedule (IRS) in the sub-tropical region of Ethiopia using the CROPWAT 8.0 model. The average crop evapotranspiration (ETC) values for all growing seasons were 27.2mm/dec (initial stage), 88.4mm/dec (developing stage), 136.7mm/dec (middle stage), and 129.2mm/dec (late season). The crop water requirement (CWR) of the onion crop was very high (mid-season), high (late-season), medium (developing season), and low (late-season). The study found that the yield reduction in onion crops was 4.3% (stage-A), 7.1% (stage-B), 9.4% (stage-C), and 4.7% (stage-D) due to water depletion. The high depletion value was recorded in the mid-growth season, while the low depletion value was recognized in the late growth season.
