e0“Drought is a major production constraint of rainfed lowland rice grown in Thailand and Laos”
e2“The results of the field experiments and simulation modelling exercises showed that the influence of these constraints can be reduced and yield increased by several methods : in particular, choice of appropriate cultivars and time of sowing to match crop phenology with water availability, application of appropriate fertilizer, adoption of high yielding cultivars, adoption of direct seeding in place of the traditional transplanting system, and reduction of percolation water loss from the paddies”

Other claims from this paper (10)
- Observation Lack of standing water at transplanting is identified as a major constraint on rainfed lowland rice
- Observation Severe water stress at the end of the growing season is identified as a major constraint on rainfed lowland rice
- Observation Low yield potential of the present cultivars is identified as a major constraint, particularly in Thailand
- Observation Adverse soil conditions are identified as a major constraint on rainfed lowland rice
- Intervention effect Several methods reduced the influence of constraints and increased rainfed lowland rice yield
- Intervention effect Application of appropriate fertilizer increased rainfed lowland rice yield
- Intervention effect Adoption of high yielding cultivars increased rainfed lowland rice yield
- Intervention effect Adoption of direct seeding increased rainfed lowland rice yield compared with the traditional transplanting system
- Intervention effect Reduction of percolation water loss increased rainfed lowland rice yield
- Recommendation Appropriate rainfed lowland rice cultivars are early flowering and short-intermediate statured
