AG 606 CROP PRODUCTION AND SIMULATION MODELING                                                                               (2L+1P) III

Objective
  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.

Theory

UNIT I
  Systems classification; flow charts, modeling techniques and methods of integration - state, rates and driving variables, feedbacks and relational diagrams.

UNIT II
  Elementary models for crop growth based on basic methods of classical growth analysis.

UNIT III
  Crop modeling methods for crop-weather interaction, climate change and variability components, DSSAT, APSIM, INFOCROP and Century models

UNIT IV
  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.

Praticals
  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.
