Effect of increased level of CO2 on growth and yield of wheat crop

The present study was carried out to evaluate the changes in growth and yield in wheat (Triticum aestivum) crop when grown under elevated CO2. Different chambers were used: ambient CO2 chamber and elevated CO2 chamber. Crop was grown from seedling to maturity inside the chamber under ambient CO2 and elevated (future) CO2 (500 ± 50 ppm). Crop resulted in greater biomass compared to ambient CO2. The high concentration of CO2 resulted into increase shoot length, root length and number of tillers in terms of their size and weight. Exposure to elevated CO2 cause significant increase in economic yield of wheat per plant. In this study we examine the effect of present and future CO2 concentration on the growth, biomass and yield of wheat crop.
