Dynamic simulation models integrate the knowledge of different sciences and disciplines and permit to study the behaviour of systems as a function of time. Simulation models can be used to support decision making on very different kinds of systems. In agricultural research, system dynamics applications have been used to understand the course of plant growth and development process. Crop growth simulation models solve the interactions between soil-plant and weather simultaneously and represent an important tool to understand the changing nature of agricultural production. The Simulation Model of Potato Production, MSPEC-PAPA, was developed to calculate daily dry matter production of potato under both potential production and water-limited conditions. The model was calibrated to simulate the growth of the cultivar Alpha on a light clay soil in San Francisco del Rincón, Guanajuato state, México. The comparison between farmer's irrigation scheduling (52 200 kg ha-1) and the simulated one (58 400 kg ha-1) showed an opportunity to increase at least by 10% the crop yield through increasing water use efficiency and optimizing the potato process of production.
