Verification of Vermicompost Technology on Faba Bean Production at Welmera District, Birbo Watershed, Central Highlands of Ethiopia

Abstract

Vicia faba, usually known as faba bean, which is commonly cultivated as a crop for human consumption, is the world’s leading source of protein. However, due to the low availability of basic cations, excess of hydrogen and aluminium in exchangeable forms, soil fertility limits its productive potential. Thus, this verification trial was intended to show the effects of Vermicompost technology on faba bean production, productivity and soil properties improvement on Nitisol of Birbo watershed in Welmera district in 2020/23. This verification work indicated that vermicompost application had contributed to the improvement of soil’s chemical properties and yields of faba bean, even if statistically non-significant results were observed. Soil chemical properties like pH, TN and OC were observed due to their application. From this study it is concluded that fifty per cent of nitrogen (0.47 ton ha-1) from Vermicompost and fifty per cent of nitrogen from urea would be recommended to be applied in the areas which have the same agro-ecology and soil properties as Welmera Districts.
