Abstract:
Vermicomposting is an emerging sector in developing country and also help in the promotion toward of the organic farming. Vermicomposting is one of the best options available at present for the treatment of organic wastes. Vermicomposting refers to natural bioconversion of biodegradable garbage into high quality manure with the help of earthworms, this methodology is sustainable agriculture production and income of farmers significantly. When design and developed of prototype machine (churning and sieving), it is necessary to study the physical and engineering properties of organic fertilizer (vermicompost) to know their manner such as, moisture content, bulk density, dry matter content, porosity, angle of repose and coefficient of friction and clods size of vermicompost were determined. Data collected of four replications with 6 different depths of heap (Treatments) in one factor FRBD design were analyzed using online Opstate statistical software. Results showed that treatment as a depth of vermicompost heap was significantly higher (p < 0.05) of significance. Analyzed data of physical and engineering were observed at different depth of heap viz., The moisture content of 13.75, 19.54, 25.47, 29.01, 34.22 and 38.48% db., bulk density of 646, 658, 683, 690, 711 and 724 kg m-3, true density of 1215, 1176, 1083, 981, 867 and 834 kg m-3, dry matter content of 86.25, 80.48, 74.55, 71.00, 65.80 and 61.53%, porosity of 47.34, 44.02, 36.93, 29.64, 18.03 and 13.25%, angle of repose of 30, 32, 35, 37, 38 and 40 o, coefficient of friction of 0.41, 0.42, 0.47, 0.48, 0.53 and clods size of vermicompost of 0.58, 0-50 mm, 50-60 mm, 60-80 mm, 80-100 mm, and 100-160 mm, respectively. The study is important to design and developed a different component of breaking and sieving machine for organic fertilizer (Vermicompost). Results are likely to be useful in assessing the quality of vermicompost used to all agricultural farming sector.
