Abstract: Tef is the major staple cereal crop in Ethiopia, mainly grown under rainfed condition. The major objective of this study was to evaluate and recommend the best performed tef varieties for the tef growers of moisture stress areas. Field experiment was conducted to select well adapted and high yielder tef varieties at Simada North western, Ethiopia during 2021/2022 and 2022/2023 main cropping season. The experiment was conducted by using 12 tef varieties through a randomized complete block design with three replications. The combined analysis of variance over years revealed a highly significant difference (p<0.01) among studied tef varieties for days to maturity, biomass yield, grain yield and harvest index and significant difference (p<0.05) for plant height. Infarct, the cultivation of improved tef varieties in moisture deficit areas is absolutely crucial for food security and income generation to the communities by enhanced tef production and productivity through using recommended varieties as compared to the farmers local varieties. So, the Two tef varieties, Mechere and Zoble provided as higher grain yield 1830kg/ha, 1824 kg/ha respectively at moisture stress area. Therefore, based on grain yield and other important traits, Mechere and Zoble varieties could be recommended for Simada district and similar moisture stressed agro ecologies.

Abstract: The field trial was conducted for three years from 2014/15 to 2016/17 to determine optimal irrigation scheduling. There were five levels of irrigation water application; 60%, 80%, 100%, 120%, and 140% of the allowable soil moisture depletion levels (ASMDL) for each of the treatments laid out in a randomized complete block design with three replications. In the study, the combined year analysis result showed that there is a significant yield difference among the irrigation water applications at a P < 0.05 level of significance. The highest yield (5.269 tone ha-1) was obtained by applying irrigation water of 80% ASMDL followed by 120% ASMDL (4.734 tone ha-1) however the least yield (4.165 tone ha-1) was observed at irrigation water application of 60% ASMDL of the recommended level which means the application of 40% less water than the FAO recommended level. There is no significant difference in water use efficiency between the treatments, but the highest water use efficiency has been observed at 80% ASMDL. The overall result of this experiment suggests that the application of irrigation water using 20% less than the FAO recommendation (100% ASMDL) can sufficiently be used for irrigation scheduling of irrigated durum wheat under central highland vertosol conditions. Therefore, to have a higher yield of irrigated durum wheat it was recommended to flush frequently before critical depletion occurred.
