The effect of CO2
enrichment in raising the temperature was realized in the Open Top Chamber
(OTC) experiment. The elevated CO2 with this level of temperature
raised grain yield and yield components of rice but varied greatly by year. The
CO2 enriched plot had lesser N, P, and K in grain, straw, and root
but higher organic carbon (OC) in the root compared to the Ambient and the
Field. The study indicated that this rise of temperature due to the elevated CO2
could not adversely affect the yield.
