Scholarcy highlights

  • The increasing shortage of water resources has led to the development and adoption of aerobic rice system, which saves water input and increases water productivity by reducing water use during land preparation and limiting seepage, percolation, and evaporation
  • Aerobic rice is a new term coined by the International Rice Research Institute, for high-yielding rice grown under nonflooded conditions in nonpuddled and unsaturated soil, which is responsive to nutrient supply, can be rainfed or irrigated, and tolerates flooding
  • The positive effect of soil sterilization on the plant growth could not confirm whether continuous cropping obstacle in aerobic rice was caused by biotic or abiotic factors. Both biotic and abiotic factors may involve in the continuous cropping obstacle of aerobic rice, recent research focused more on abiotic factors associated with continuous cropping obstacle including soil pH increase, nutrient deficiencies, and ammonia toxicity
  • Yield decline resulting from continuous cropping of aerobic rice is a major constraint to the widespread adoption of aerobic rice technology
  • Research on identifying biotic and abiotic factors associated with continuous cropping obstacle of aerobic rice has been conducted
  • Both biotic and abiotic factors were reported to be responsible for the yield decline of continuously monocropped aerobic rice, abiotic factors such as soil pH increase, nutrient deficiencies, and ammonia toxicity have received more attention in recent years
  • It is necessary to study the sustainability of aerobic rice in diverse environments with different soil physical and chemical properties, soil fertility, and water availability
