Abstract

In recent years, the Asian monsoon region has a large business opportunity for the global food market for Japan. In this study, the authors evaluated the crop growth conditions and energy of greenhouse tomato production in several Asian monsoon areas. In these evaluations, a cultivation simulator considering growth conditions was used. In the calculation of the energy required to maintain the cultivation environment of the greenhouse, the photosynthesis rate of the plants and the transpiration rate were also calculated by simulation. As a result, the difficulty of greenhouse tomato production under high temperature and humidity conditions in Asia and the differences in crop growth conditions among these regions could be clarified by this analysis. In the future, it was suggested that it would be necessary to reduce the temperature of the greenhouse while maintaining the amount of photosynthesis.
