Modeling water availability, crop growth, and yield of rainfed lowland rice genotypes in northeast Thailand

Fukai, S. | Basnayake, J. and Cooper, M.
Characterizing and understanding the nature of the limitations imposed by rainfed lowland environments within a target region are important for developing an efficient rice breeding program. Major factors determining the environment as it influences plant performance are soil properties and water availability. Rainfall is a major determinant of the water environment, but its seasonal variability is high in northeast Thailand. Simulation models are useful in determining many features of the paddy water environment, as they can readily estimate water availability as a probability function by using past rainfall patterns as inputs. The RLRice model was developed for stimulating the paddy water balance and growth of cultivar KDML105 for the rainfed lowlands in Thailand.
