Evaluación del efecto de la concentración de CO2 en el crecimiento y rendimiento de Pisum sativum L. mediante un invernadero automatizado con control difuso

The objective of this research was to evaluate the influence of CO2 concentrations on morphometric and physiological variables, as well as on pea yield in Pamplona, North Santander. The research was conducted in an automated experimental greenhouse built at the University of Pamplona. One greenhouse was tested at a CO2 concentration of 1300 ppm, while the other was tested at 600 ppm. Morphometric and physiological variables, including pod number, grain number, and grain weight, were measured. Significant increases were observed in height, leaf number, number of lateral shoots, and leaf surface area, but not in stem diameter and chlorophyll index. Higher CO2 concentrations led to an increase in leaf area in pea plants, which was reflected in a higher pod number, grain number, and grain weight.
