[Data] Comparison of Local CO2 Application Effects on Tomatoes and Colored Peppers

In the cultivation of tomatoes and colored peppers, localized CO2 application within the crop can effectively improve yields.

Using liquefied carbon dioxide (carbonic gas) and porous tubes installed within the crop area, a method of applying CO2 during the day with target concentrations of approximately 440 ppm in summer and autumn, and 500 ppm in low-temperature periods, can maintain the CO2 concentration inside the facility higher than that of the outside air, which is effective in increasing yields in tomato and paprika cultivation. This document includes specific data showing that when applied to tomatoes, the marketable yield in the CO2 application area increased by 29% compared to the non-application area, and that when applied to colored peppers, a yield increase effect of over 60% was observed in the CO2 application area. 【Contents】 ■ CO2 application methods: filling method and localized application ■ Localized application equipment and target CO2 concentrations ■ Specific data (comparisons between CO2 application and non-application areas during tests in 2016 and 2017, CO2 concentration transitions, marketable yield, and increase in revenue) *For more details, please refer to the PDF document or feel free to contact us.
