Advanced resource management and conservation technologies in wetland rice are system of rice intensification (SRI), integrated crop management (ICM), aerobic rice culture etc in the context of farmer's realities in lowland rice ecosystem in North - Eastern Region of India. The management of these technologies in wetland rice cultivation could conserve resources like seeds, water, nutrients, reduce cost, soil health and environment which leads to higher yield compared to conventional rice culture (CRC). The main reason for none or less-adoption of SRI and ICM technologies in rice cultivation in North-Eastern Region of India might be related to more efforts, faith towards traditional weed control methods, lack of knowledge and water management. It is important to understand the performance of any new technology in the context of farmer's realities, which are always more complicated and more diversified than on any research station. This book might definitely help for the researchers, academicians and students in their future career.
