With the ever increasing demand for food accompanied by the constraints of climate change and the availability and quality of soil and water, the farmers are challenged to produce more food per hectare with less water and with fewer agrochemical inputs if possible. The ideas and methods of the system of rice intensification which is improving irrigated rice production are now being extended and adapted to many other crops viz., wheat, maize, finger millet, sugarcane, legumes, vegetables, and even spices. Promoting better root growth and enhancing the soil’s fertility with organic materials are being found effective means for raising the yields of many crop plants with less water, less fertilizer, reduced seeds, fewer agrochemicals, and greater climate resilience. The principles and practices that improve the productivity and resilience of these varied crops are broadly referred to as the system of crop intensification (SCI).
