Efficient use of water for maximum production of aerobic rice (Oryza sativa l.) A research review

Aerobic rice is a production system where rice is grown in well-drained, non-puddled, and nonsaturated soils. Water savings from land preparation, no transplanting costs, seed costs and labour costs from sowing to harvest varied from 520 to 650 mm, compared with 1200-1300mm in lowland rice. The aerobic rice cultivar must have better yield performance of low land condition and better drought performance of upland condition with desired root traits. Nematode and weed infestation are the major problem for yield decline due to changes in soil nutrient level and growth inhibition by toxic substances from root residues are key point for poor yield of continuous aerobic cultivation.
