ABSTRACT
Recently, there is a need to enhance the rice yield to meet the global food security. Several novel techniques such as rice intensification and integrated crop management are being practiced for efficient production with better soil health and yield. The characteristics of system of rice intensification (SRI) typically include the raised-bed nursery, transplanting younger seedlings with a wider spacing, keeping water to saturation level, weeding and incorporation of weeds in soil, and utilization of organic fertilizers. SRI aims at the reduction of quantity of irrigation water along with the reduced seed rate. The proper adoption of SRI improves the income per drop of water. The SRI is the good alternative under the intense water scarcity, climate change, and costly inputs conditions. This chapter provides the fundamentals of SRI, its principles, practices and environment impact, and recent trends in the dynamics of SRI.
