Interaction between increased CO2 and temperature enhance plant growth but do not affect millet grain production

The intergovernmental panel on climate change predicts a progressive increase in atmospheric CO2 concentration and temperature; however, their effects cereals have been shown for limited number of species. This study evaluates the increased temperature separately combined millet growth grain production open-top chambers where microclimate was adjusted to following conditions: ambient enriched (~ 800 ppm) higher (+3ºC); CO2-enriched temperature. For each treatment, two were used, containing 15 7 L pots. Each pot received five seeds at beginning experiment thinning one plant per days after sowing. Ten plants harvested from chamber 65 sowing height, leaves longest root length as well shoot biomass measured. remaining 130 evaluate production. results indicate that high levels did not affect biomass. On other hand, subjected grew 7% taller than those grown under Contrastingly, submitted both elevated 19% had 22% more However, any environmental conditions. We provide evidence millets are tolerant predicted changes potential may be affected.
