Sistema de control automático de variables climáticas para optimizar el rendimiento de cultivos bajo cubierta

Abstract

Introduction: The article derives from the research “Design of a system for the control and automation of temperature, soil moisture, and relative humidity to optimize greenhouse crop yields at Corhuila” conducted at Corporación Universitaria del Huila between 2016 and 2017. Aim: To improve growth rates of greenhouse crops. Methods: The study was based on a comparison of growth and number of fruits between greenhouse and outdoor tomato crops; said items were monitored weekly by direct observation of the two groups of crops. Results: Development during the first five weeks was similar; as of the seventh week, the greenhouse crop had 38 % more branches, equal number of fruits and was 28% higher; on week 13, the differences increased to 64 % in the number of branches, 65% in the number of fruits and 55% in height. Conclusion: It was proved that the implementation of this technological solution can promote an increase in the growth and production rate reached by plants. Originality: Development of an electronic system for the agricultural sector in an intermediate region of Colombia to improve the efficiency of crops. Limitations: The lack of Internet access made it impossible to implement a web-based control system.
