Organic Management Practices to Enhance Nitrogen Use Efficiency in Rice

Naleeni Ramawat, Renu Yadav

Abstract :

Nitrogen is very important element and its losses from the soil are enormous. It is lost from the soil in different ways as leaching and erosion, volatilization and denitrification. In India managing organic farming systems is a major challenge due to strong N limitation. Our methodology is mainly based on a better utilization of the natural nitrogen resources from soil mineralisation and symbiotic fixation of legumes, and not by an increase in the use of organic fertilizer. The focus is also to increase production and productivity, maintain soil health, reduce nutrient losses, Organic farming offers alternative system for sustainable production and natural resource system. The aim of nutrient management in organic systems is to optimize the use of on–farm resources and minimize losses. Organic materials such as, biofertilizers and cover crops are other valuable source of nutrients to improve the growth and yield attributes, yields, nutrient uptake, grain quality and soil fertility. The rice (Oryza sativa L.) - wheat (Triticumaestivum L.) cropping system occupies about 28.8 million hectares mainly spread over Asia’s five countries, namely, India, Pakistan, Nepal, Bangladesh and China. The paper outlines the organic farming management practices to enhance Nitrogen Use Efficiency (NUE) of rice-based cropping systems.
