DESCRIPTION OF COURSES
AG 606 CROP PRODUCTION AND SIMULATION MODELING (2L+1P) III
To familiarize the students about systems approach and to simulate yields and growth of crops under varied soil and weather conditions with different management practices, and their optimization.
Systems classification; flow charts, modeling techniques and methods of integration - state, rates and driving variables, feedbacks and relational diagrams.
Elementary models for crop growth based on basic methods of classical growth analysis.
Crop modeling methods for crop-weather interaction, climate change and variability components, DSSAT, APSIM, INFOCROP and Century models
Potential production: leaf and canopy CO assimilation, respiration, dry matter accumulation, crop phenology and dry matter distribution and development in different crops. Estimation of generic coefficients.
Creation of management files for simulation. Simulation of elementary models for crop growth. Simulation of potential production. Simulation with limitations of water and nutrient management options. Sensitivity analysis using different climatic years and crop management practices.
