Abstract:
Excessive application of the chemical fertilizers is to attain higher yield that has not only reduced the nutrient use efficiency but it also adversely affect the soil productivity, soil micro-organisms and environmental stability. Because of this reason, immediate conversion to organic farming would drastically reduce production at initial phases which is of major concern to feed the growing population. This review article has written with the prime focus to notify on the impact of inorganic, organic and biological sources of nutrients in rice. Organic manures like farm yard manure, poultry manure, vermicompost, press mud and coir pith compost and biological sources of nutrients like biofertilizers, zinc solubilizing bacteria, seaweed extract are given prioritized due to local availability with integration with inorganic fertilizers to give nutrients like nitrogen, phosphorus, potassium and zinc on growth and yield of rice. From the study, integrated nutrient management is best practice than chemical fertilizers and also to over complete shift of organic cultivation in terms to improve productivity and also to maintain soil health in a long run. Application of organic sources of nutrients can be made from local availability to decrease the cost of cultivation over inorganic fertilizers.
