Abstract:
The water crisis is threatening the sustainability of the irrigated rice system and food security in Asia. Our challenge is to develop novel technologies and production systems that allow rice production to be maintained or increased in the face of declining water availability. Water shortage is becoming severe in many rice-growing areas in the world, prompting the introduction of water-saving aerobic rice, which is direct-seeded in non-puddled, nonflooded aerobic soil, aerobic rice systems can reduce water use in rice production by as much as 50% ‘Aerobic rice’ and ‘upland rice’ are both grown under aerobic conditions. This paper introduces principles that govern technologies and systems for reducing water inputs and increasing productivity. We concluded that, Sanda technology mainly knows as double transplanting increases yield up to 8-10%.
