Three types of composting viz., Mechanized drum compost, vermicompost and FYM were prepared by using 1:3 ratio of wet and dry waste to assess the duration of compost period and quality of the compost. Among the three methods, the compost prepared from the mechanized drum compost was found superior in terms of physical, chemical and biochemical properties. The Mechanized drum composter took 35 days to composting, vermicompost 75 days and FYM 120 days. A pot culture study was conducted in green house to assess the quality of three methods of compost on soil properties, uptake, growth and yield of the French bean using eleven treatments in CRD design with three replications each. The yield and nutrient uptake of French bean was significantly highest with the application of 100 % NPK+ Mechanized drum compost. At harvest of French bean there was increase in major nutrients, secondary and micronutrients in soil with the application of 100 % NPK + Mechanized drum compost. Hence the use of Mechanized drum compost along with NPK fertilizers increases the concentration of nutrients in the soil and also increases the growthand yield of the crop.EnglishThesis
