Accurate quantification of irrigation water requirement at different physiological growth stages of crops is important to prevent over or under irrigation. A study was carried out to determine the crop water requirement and irrigation scheduling of the selected vegetable crops grown under irrigated conditions at Holeta, Central Highland of Ethiopia. The crops include, cabbage, and tomato. By using the 30-year climatic data, the crop evapotranspiration (ETc), reference crop evapotranspiration (ETo), and irrigation water requirement for each crop were determined using the CROPWAT model. The study shows that the total CWR of cabbage, and tomato was estimated to be 426.6mm, and 497.7mm respectively, and the total GIR of cabbage, and tomato was found to be 598.3 mm, and 691.7 mm respectively. for early January planted cabbage, irrigation should be given twelve times ( 1-Jan, 9-Jan, 16-Jan,24-Jan, 2-Feb, 11-Feb, 21-Feb, 5-Mar,15-Mar, 25-Mar, 2- Apr and last irrigation on 12-Apr) with a gross irrigation water amount of 59.8mm, 32.5mm, 31.5mm, 35.2mm,42.2mm,43.3mm,48.1mm, 52mm, 51.3mm, 49.5mm, 51mm, and 51.7mm depth respectively. Similarly for early January planted tomato, irrigation should be given twelve times (1-Jan, 5-Jan, 10-Jan, 16-Jan, 21-Jan, 29-Jan, 6-Feb, 15-Feb, 26-Feb, 12-Mar, 26-Mar, and the last irrigation on 10-Apr) with a gross irrigation water amount of 53.9mm, 19.3mm, 25.5mm, 30.7mm, 30.6mm, 36.4mm, 47.8mm, 58.5mm, 73.4mm, 83.5mm, 80.9mm, 80.7mm irrigation depth respectively. This study might be useful to prevent over or under irrigation which will help in effectively planning and management of irrigation water in the district.

Tef is a foremost staple cereal crop with substantial contribution in the GDP of Ethiopia. Tef grain is highly nutritious gluten-free as well as high quality forage. However, lack of improved tef varieties reduced the production and productivity of tef in Assosa areas. Hence, the objective of this study is to demonstrate and create awareness about the recently released improved tef varieties for target area. The three recently released improved tef varieties (Dursi, Ebba, Areka-1) and standard check Quncho variety was evaluated on plot size 10m by 10m at adjacent plots. The highest grain yield (1413.68 kg per ha) was obtained by Dursi variety while the lowest grain yield (894.24 kg per ha) was recorded by Quncho variety. The demonstrated tef varieties were Dursi, Areka-1 and Ebba had yield advantage over standard check (Quncho) variety by 36.74%, 14.33% and 9.63%, respectively. Based on selection criteria such as grain yield, plant height, panicle length, diseases resistance and seed color farmers were selected Dursi variety. Based on grain yield obtained and farmers’ selection criteria we recommended that Dursi tef variety will give better yield for target area.

Background: This study was designed to measure farmers’ willingness to pay for mechanized rice harvesting technology rental service. Specifically, the study addresses how much they are willing to pay and what factors hinder farmers' WTP for mechanized rice harvesting technology by using a one and one-half bounded elicitation Contingent Valuation method and the Craggit econometric model. Methodology: Selecting representative samples for this study involved using a multi-stage sampling strategy. A total of 190 smallholder farmers were randomly selected to collect primary data. Results: The result revealed that nearly four-fifth of the sample respondents were willing to pay for mechanized rice harvesting technology rental service. Besides, smallholder farmers' willingness to pay for mechanized rice harvesting technology rental service varies between 200 and 1900 birr, with an average value of 890.46 birr per timad. Conclusion: Moreover, the model result indicated that sex of the respondent, family size, access to extension service, access to training, participation on field day, and livestock ownership had positive and statistically significant effect on mechanized rice harvesting technology rental service. Thus, in order to offer smallholder farmers with more access to technology at a reasonable rental cost, policymakers, development workers, researchers, and rental service providers should collaborate.
