16 Dec Integrated Nutrient Management in Vegetable Production
सब्जी उत्पादन में एकीकृत पोषक प्रबंधन Integrated nutrient management (INM) is an approach to soil fertility management that combines organic and mineral methods of soil fertilization with physical and biological measures for soil and water conservation. INM adopts a holistic view of plant nutrient management by considering the totality of the farm resources that can be used as plant nutrients. Integrated nutrient management is based on three fundamental principles: maximize the use of organic material ensure access to inorganic fertilizer and improve the efficiency of its use minimize losses of plant nutrients Research gaps in integrated nutrient management The research gaps include: Mismatching of INM practices developed at research stations with the farmers resources and their practices INM recommendations for different crops are not based on soil testing and nutrient release behaviour of the manures Nutrient balance/flow analysis vis-a-vis soil fertility management practices with special reference to INM at farm level needs to be worked out Nutrient release characteristics of farm residues in relation to their quality to develop decision support systems Biofertilizers were not included as component of INM in many cases; and Integrated Farming Systems approach needs to be encouraged for sustaining livelihood in rural areas particularly for small and marginal farmers. Role of biofertilizers in INM Different types of biofertilizers available at present among that Rhizobium is relatively more...
