Application of CSM-CERES-Rice model for assessment of plant density and nitrogen management of transplanted rice for tropical environment
Research Type
Departmental Research
Experiment Background
India is the second largest producer of rice in the world after china. It has an area of 43 million hectares with production of 99 million tones and 3.45 t/ha productivity. Crop simulation models are principal tools needed to brining agronomic science into information science. CERES-rice model is a process based management-oriented model that can simulate the growth and development of crop, with these crop model it possible to simulate a living plant through the mathematical and conceptual relationship which governs its growth in the soil-water-plant-atmosphere. Crop simulation model explain much of the interaction between the environment and the crop. These model predicted the performance of a particular cultivars, sown at any climate and would lead to information on transfer of agro-technology. CERES-rice model is a process based management oriented model that can simulated the growth and development of rice crop also provides validation of crop outputs and thus users can compare simulated outcome with observed results. Such validated model can also take the information generated through site specific experiment and trial to other sites years (Ritchie et al. 1988). Model is also helpful for advance simulation of crop performance under different environment and it is essential for planning of crop practices.
In this study the (CSM)-CERES-Rice model is used to simulate of the phenology and yield of Gurjari variety in south Gujarat under different plant density’s and nitrogen application levels.
