The impact of vermicompost application on yield of maize (Zea mays)

Pollution of agriculture in ecosystem is due to excessive use of mineral fertilizers and discharge of livestock manure. Therefore, there is a need for disposing manure safely for instance by transforming manure into compost. The traditional composting is, however time consuming with considerable nutrient loss. Vermicomposting is a new and good method, but do far, there are few quantitative evaluations of vermicomposting. There we compared vermicomposting ans traditional composting if cattle manure with maize. The result show that the amount of nutrients from vermicomposting is lower than that from traditional compositor mannuring vermicomposting yield 2172.0kg of earthworms per hectare. Moreover vermicomposting increased aboveground biomass by 7.7% and maize grain yield by 18.35%. The global output of vermicomposting was thus higher 304% due to higher grain yield.
