POTENTIAL PRODUCTION OF BORO RICE IN THE HAOR REGION OF BANGLADESH .1. THE SIMULATION-MODEL, VALIDATION AND SENSITIVITY ANALYSIS

To study rice production in the Haor region of Bangladesh, a model was developed to simulate the growth duration, biomass, grain yield and quality, and to assess the economic implications for the crop. The model's prediction of dry matter production and grain yield in the paddy field accorded well with field data from other experiments. The model also showed sensitivity to some of the biological parameters, viz. the extinction coefficient for visible light, initial light use efficiency for individual leaves maximum rate of gross photosynthesis of single leaves, and development rate constant at the reproductive stage.
