Full Project Title: Developing a system of temperate and tropical aerobic rice in Asia (STAR) (PN16)

Introduction

Asia’s traditional irrigated rice production, requiring submerged soil conditions and much water compared with other crops, is constrained by declining availability and increasing costs of water as well as lack of rainfall in rain-fed farming areas. Water-use efficiency is critical to help safeguard food security for rice farmers living in water-scarce areas.

Aerobic rice is a production system in which specially developed, input response rice varieties with “aerobic adaptation” are grown in well-drained, non-puddled, and non-saturated soils without ponded water. It holds promise for farmers in water-scarce irrigated or rain-fed environments where water availability at the farm level is too low, or where water is too expensive, to grow flooded lowland rice.

In this CPWF project, strategic research in three benchmark basins, Yellow River, Indo-Ganges, and Mekong, aimed to develop sustainable aerobic rice systems for water-scarce irrigated and rain-fed environments in Asia with the key objectives to: 1. Identify and develop aerobic rice varieties with high yield potential 2. Develop insights into key processes of water and nutrient dynamics 3. Identify key sustainability issues, and propose remedial measures 4. Develop practical technologies for crop establishment 5. Characterize and identify target domains.

Research Highlights

Research highlights

  • Breeding of aerobic rice varieties is most developed in China where the project obtained maximum yields of 6 t ha-1 under well-defined experimental conditions.
  • In India, tropical aerobic rice varieties with 4.5 t ha-1 yield potential were identified (Pusa Rice Hybrid 10, Proagro6111, Pusa834, Apo (PSBRc9).  However, these varieties had a relatively lower tolerance to dry soil conditions than the Chinese varieties in that soil water tensions had to stay below 30-40 kPa to reach these high yields.
  • Under rain-fed conditions in Laos and Northeast Thailand, breeding lines were identified with yield potentials of 2 (NE Thailand) to 3.5 (Laos) t ha-1.
  • Adoption of aerobic rice will (among others) depend on relative market prices the different crops available to farmers are expected to fetch in a particular year, the degree of water scarcity, availability of quality seeds and extension support, and farmers’ preference to grow their own rice for self sufficiency rather than depending on markets.
Project Outcomes

Project outcomes

  • Extrapolation domain construction and scenario analysis (by CPWF-Impact Study) suggest that aerobic rice can have large impacts in India and countries in the lower parts of the Mekong Basin.
  • The aerobic rice technology can be considered sufficiently mature for dissemination in the Yellow River Basin (YRB), but not so for most of tropical Asia where more R&D is needed to create sustainable and high-yielding aerobic rice systems.
