Abstract
Barley (Hordeum vulgare L.) was domesticated at about 8000 B.C. It is one of the most important cereal crops in Ethiopia, accounting for over 60% of the food of the peoples living in the highlands of Ethiopia. Soil acidity is expanding in its scope, about 43 % out of the total cultivated land in Ethiopia, is dominated with acidic soil, as a sensitive highland crop, barley productivity is decreasing due to soil acidity and in areas where the problem is severe the crop is going out of production. A greenhouse pot experiment was conducted with the objective of performance comparison and screening of soil acidity-tolerant barley genotypes. The treatments consisted of two lime levels (with and without lime) and ten barley genotypes making up a total of 20 treatments laid out in a completely randomized design with six replications. Crop phenology, growth parameters, yield and yield components were evaluated. Primary root length, lateral root length, lateral root number, and root dry weight were significantly (P < 0.05) affected by the application of lime. Stand count at harvest, above-ground biomass, plant height, total seed number per pot, and seed number per plant were significantly (P < 0.05) affected by the application of lime. Accession 215454a, has shown a greater value of relative root length measurement with 73.76 centimeter. The study revealed the impact of soil acidity could be so severe it can result to the extent of having no yield as compared to lime-treated soils. This necessitates the use of lime in areas that are prone to acidic soils. Overall, the accession that showed relative tolerance from early stage screening can be candidate for further breeding program to develop barley variety that is tolerant to acidic soils.
