Integrated Analysis of Yield Performance, Physicochemical and Nutritional Quality Traits of Grain in Selected Food Barley (Hordeum Vulgare L.) Varieties for Sustainable Production in Legambo District of South Wollo Zone, Ethiopia

Barley (Hordeum vulgare L.) is a key cereal crop vital for food and nutritional security in Ethiopia’s highlands. However, limited studies have evaluated the yield, adaptability, and nutritional quality of improved barley varieties under the specific conditions of Legambo District, South Wollo Zone. This study aims to assess the agronomic performance, physicochemical properties, and nutritional quality of four improved barley varieties: EH1493, HB1307, HB1965, and Hagere, grown under local field conditions. The experiment will follow a Randomized Complete Block Design (RCBD) with three replications. Data on yield, proximate composition, bioactive compounds, minerals, and beta-glucan content will be analyzed using standard AOAC methods and GenStat software at the 5% significance level. Soil properties will also be evaluated before and after cultivation. The study will run from November 2018 to October 2019 E.C., encompassing soil sampling, field experiments, laboratory analysis, data processing, and report preparation. The total project budget is 874,388 Birr, covering materials, laboratory costs, researcher allowances, transportation, and dissemination. The expected outcome is to identify high-yielding and nutritionally superior barley varieties suited to the Legambo agroecology. The results will support improved barley production, local value addition, and national food and nutrition security efforts while also contributing to scientific publications and community outreach.
