Determination of Carbon Dioxide Concentration in CO2 Supplemental Greenhouse for Tomato Cultivation during Winter and Spring Seasons

Abstract

This study was aimed to determine the changes in CO 2 concentration according to the temperatures of daytime and nighttime in the CO 2 supplemental greenhouse, and to compare calculated supplementary CO 2 concentration during winter and spring cultivation seasons. CO 2 concentrations in experimental greenhouses were analyzed by selecting representative days with different average temperatures due to differences in integrated solar radiation at the growth stage of leaf area index (LAI) 2.0 during the winter season of 2022 and 2023 years. The CO 2
