Abstract :

Quality of different on- farm produced compost viz. Vermicompost, Biodynamic, Indigenous, and Novcom compost were evaluated along with their post soil application effectivity during 2009-2012. The result showed better qualitative aspects of Novcom compost as compared to others in terms of total NPK content (13.0 %), total microbial count (at least 103 to 106 times higher c.f.u.) and germination index (21.3 % higher than the 2nd best value) as also substantiated by the high compost quality index. Simultaneously Soil Development Index (SDI), which indicated the variation/ enhancement in different soil quality parameters by a single understandable value; was found to be highest in case of Novcom compost applied plots (54.72) followed by plots receiving Biodynamic (37.81), Vermicompost (32.05) and Indigenous (24.82) compost. Evaluation of crop yield visa-vis SDI value under different types of compost application indicated strong positive correlation between the two.
