These cereal-cereal based cropping system are highly nutrient demanding and mainly grown under inorganic nutrition conditions. But the low income of small and marginal farmers restricts the use of costly chemical fertilizers on one hand and nutritional imbalance arising from continuous use of inorganic fertilizers necessitate the research and use on other source of nutrient. Under this situation the use of organic manures has been found to be promising in arresting the decline in productivity through correction of deficiency of secondary and micro nutrients, and improving physical and biological health of the soil as well. Although, organic are eco-friendly and sustain productivity but their limited availability and lower nutrient status are the major constraints in the use of these alternative sources of plant nutrient in the agriculture production system. These constraints can be overcome by the judicious use of manures and fertilizers in an integrated manner for maintaining the economic crop production and soil fertility status on long term basis. It is commonly believed that the judicious combination of organic and inorganic fertilizer increase synchrony and reduce losses by converting inorganic nitrogen into organic forms and important not only for enhancing the efficiency of the fertilizers, but also in reducing environmental problems that may arise from their use. Apart from supplying nutrients, the application of organic substances, including FYM, also provides growth-regulating substances and improves physical, chemical and microbial properties of the soil. In recent years, a new cost effective concept of Subhash Palekar Natural Farming (SPNF) is claimed to the production and maintain the ecological balance. It is based on the principle of utilizing cheap and locally available inputs with zero utilization of chemicals in any form like fertilizers and pesticides. The principle methods of SPNF include mulching, Whapasa, intercropping and use of several preparation like Beejamrutham, Jeevamrutham, Ghan-jeevamrutham, Neemastra, Brahmastra, and Agniastra. One of the major components of this farming is rearing of indigenous cattle whose urine and dung are critical ingredients of Beejamrutham and Jeevamrutham. Beejamrutham contains beneficial free living nitrogen fixers, phosphorus solubilizers and bacteria producing plant growth promoting substances which help in the improvement of seed germination, seedling length and seed vigour index of crops. Jeevamrutham prepared on - site is central to this practice, enhances microbial activity in soil and helps in improvement of soil fertility. Jeevamrutham is claimed to be a panacea for pest management. But this needs experimental testing on a long term basis.
