"According to Bin Zaher et al. (2021), eddo (Colocasia esculenta) is "the most widely cultivated taro crop in Japan" and will likely grow in importance as a staple food across the world as human population increases.
... inside sunlit greenhouses where they grew eddo and rice for five weeks (from the early vegetative growth stage through the intermediate vegetative growth stage) under one of two CO2 concentrations
(~415 ppm for ambient air and
~615 ppm for elevated CO2 air,
with the elevated CO2 applied during the hours of 0330 and 1930 daily)
at low or high temperatures in two growing season years (2018 and 2019).
The results indicated that elevated CO2 had a positive impact on the photosynthesis and growth of both eddo and rice ...
With respect to the influence of temperature, high temperatures also had a positive influence on eddo ...
... yields should increase in these two important crops as atmospheric CO2 concentrations rise, regardless of whether or not temperatures increase.
Figure 1. (below):
The percentages in red text indicate the percent increase in dry weight due to elevated CO2 at a given temperature in a given year for eddo or rice.
Figure 2. (below):
Effects of carbon dioxide and temperature on the net photosynthetic rate of eddo and rice plants in 2018 and 2019. ...
The percentages in red text indicate the percent increase in net photosynthesis due to elevated CO2 at a given temperature in a given year for eddo or rice. ..."
