During the last decade organic agriculture has progressed as a dynamic alternate farming system. This has been necessitated by resource degradation because of achieving high yields in various crops to meet the increasing demand of food by the burgeoning population. This has resulted degradation of soil structure, imbalance in micro-organisms and organic matter of the soil and brought in health and environmental problems. Change from conventional to organic farming takes 2–3 years for establishment of same yield magnitude. Use of organic sources of nutrients helps to conserve the soil health by maintaining equilibrium of organic matter as indicated by 59.8, 177.4, 279.2, 63.0 per cent increase in mineralizable N, labile C, phosphatase activity, dehydrogenase activity respectively over chemical farming. The quality parameters especially reducing sugars in onion also improved with organic farming.
