ABSTRACT
A Crop Simulation Model is a mathematical model which describes crop growth and development processes as a function of environment, soil conditions, and crop management. Models were initially intended to improve understanding of crop behavior by illustrating crop growth and development in terms of physiological mechanisms. The crop simulation models are classified into different groups or types depending upon the purpose for which it is designed. Agricultural systems are managed ecosystems comprised of biological, physical and human components operating at various scales. Crop simulation models are useful tools for estimating regional crop productivity. Quantifying the impacts of plant pests and diseases on crop yields is one of the most important research questions for modeling agricultural simulation. Crop Insurance is risk mitigation effort to support the farmer in times of distress. Yield predictions were obtained from the Aqua Crop model which was validated for four different crops.
