摘要
Soil health and grain quality are the indicators of sustainability of agriculture. Obviously, there is need to promote the use of organic fertilizers by reducing dependence upon chemical fertilizers. The present study has been aimed to design, fabricate and test the worm sieving machine for vermi-compost production. Disproportionate weight theory was applied to produce jerk during manual and motorized operation. The maximum output (7.4 q/h) and maximum sieving efficiency (98 %) was found under motorized operation as compared to those (3.6 q/h and 96 %, respectively) under manual operation. Financial gain of US$ 7.73 and US$ 6.87 per tonne was observed under motorized and manual operation respectively over conventional method.
