TAILIEUCHUNG - More rice, less water-precision water management approaches for increasing water productivity in irrigated rice-based systems under north IGP: A review

Water is a critical input for productivity enhancement especially of field crops. Its judicious and optimum use is needed utmost for realizing higher resource use efficiency and plugging gaps in production. Key technological interventions, which could alter or rectify the usage pattern or strategies in freshwater utilization in agriculture, are the need of the hour. Precision water management approach could help in conserving and making more-efficient use of scarce water resources through integrated management combined with selected external inputs/technologies. In this context, the scientific interventions on water management involving precision levelling of land, no tillage or reduced tillage systems, furrow irrigated raised bed planting systems and other inclusive technological practices could enforce appropriate water management schedules. The potentials for water savings in rice production appear to be very large. But we do not know the degree to which various farm and system interventions will lead to sustainable water savings in the water basin until we can quantify the downstream impact of the interventions. Studies on the economic benefits and costs of alternative interventions are also lacking. Without this additional information, it will be difficult to identify the potential benefits and the most appropriate strategies for increasing irrigation water productivity in rice-based systems. During the crop growth period, the amount of water usually applied to the field is much more than the actual field requirement. | More rice, less water-precision water management approaches for increasing water productivity in irrigated rice-based systems under north IGP: A review
