Rice (Oryza sativa L.) is one of the most important food grain crops of more than 60 percent of the world's population. About 90 per cent of all rice grown in the world is produced and consumed in the Asian region. INM approach is flexible and minimizes use of chemicals but maximize use efficiency and improve the soil health. Change in cropping sequence with respect to availability of resources, the integrated approach of nutrient supply through inorganic and organic has become very much promising in building soil health and quality of produce. The integrated nutrient supply system is the most logical concept for managing long term soil fertility and productivity. This research book is useful for students, researchers as well as scientist for future production strategies.
