Abstract
To obtain organic fertilizer of high NPK content by employing the vermi-composting technique. The sample which we used consists of various organic wastes, dungs and waste water sludge. And the earthworm employed for vermi composting process was Eisenia foetida. As a result of vermi composting process the fertilizer obtained consists of 2.15% nitrogen, 2.10% phosphorous and 2.15% potassium. Also a case study on the growth of red spinach plant was observed by blending the organic fertilizer with that of the chemical fertilizer and compared with the growth of the blended proportion with biological fertilizer.
