摘要：Aim of the present study was to produce vermicompost from organic solid wastes by using red earth worm, Eisenia fetida and to check growth promoting and pest suppression properties on cabbage, Brassica oleracea . The mass of 100 kg of various organic waste sources were collected from Gondar and used to prepare vermicompost. The vermicompost was prepared in the month of June-August 2011 and tested on cabbage, B. oleracea from October 2011 to February 2012. Vermicompost was applied at the rate of 25, 50, 100 and 200 gm/plant individually. Each application 10 plants were selected and vermicompost application was continued on bimonthly basis. Totally 40 plants were used for control group in which 10 plants were selected randomly. Total number of leaves per plant; leaf length and width; plant stand height and root length; cabbage head round distance and weight and aphid population built-up were the parameters studied in experimental and control cabbage plants. Significant differences (p<0.05; LSD) were observed in the growth and development and pest infestation level between vermicompost applied and control plants. The number of plant stand height, cabbage head, leaves of cabbage were also significantly different (p<0.05; LSD) in experimental cabbage compared to control. Maximum number of cabbage plant was infested by aphid in control than experimental groups. In conclusion vermicompost have significant impact on cabbage growth promotion and reduce the aphid infestation. In future using vermicompost to all kinds of crops and adopting it as commercial fertilizer may create job opportunity to small scale farming society. Also, in this ever escalating cost of chemical fertilizers, the use of vermicompost seems to be quite reasonable in agro-management and should be inclusive as one of the elements of poverty alleviation strategies in such as Ethiopian context.
