- Abstract
Increased competition for the use of water resources can lead to conflicts over the use of water and, managing irrigation efficiently is undoubtedly one of the main solutions for the correct management of water resources. The use of computational tools can simplify the management of water resources. The Simulation Model for Irrigation Strategies (MSEI) details the management of irrigation in a simulated way over a long period of time, providing information that can serve as a basis in decision making for later years. In this way, this work aimed to know the influence of some climate and plant variables on the total irrigation depth through the MSEI. To conduct the study, they were adopted information of soil and climatic conditions of the Brazilian Cerrado. It was considered 31 years of reference precipitation and evapotranspiration. As a study variable, the effective depth of the root system was adopted. In the years when accumulated precipitation events were higher, the demand for irrigation was lower. While in the years of lower rainfall, the demand increased for all depths of the root system. In the years of lower precipitation rates, demand increased for all depths of the root system. The MSEI allowed the simulation of different scenarios of the irrigation blade with agility and confidence.
