Usage of bio-fertilizer&bio-pesticides, organic farming (Bernhard Berger, 2001), Biodynamic farming (Planning Commission, 2001) low input agriculture (http://www.ileia.org/), permaculture (Allan Atkisson, 1991), sustainable agriculture (Pretty J. 1998), integrated farming practices (integrated pest management and integrated nutrient management), are some of the practices that are being espoused by proponents both in developed and developing countries. All these practices have evolved as alternatives to chemical use in agriculture keeping in view the increasing demand for green agriculture products across the world (Gilk Paul, 2003). This growing demand for green agriculture products is botha constraint as well as window of opportunity not only for the agriculturists but also for producers, suppliers and traders of agriculture inputs (fertilizer, pesticide etc.) and outputs (http://www.etagriculture.com).
