Increase in the concentration of greenhouse gases (GHGs) led to global climate change has both direct and indirect effects on crop production. An experiment was conducted in IARI farm, New Delhi during the kharif season of year 2017 to quantify the effect of elevated CO2 and temperature on yield attributes as well as spikelet sterility of rice crop. Rice seedlings were transplanted in crates placed inside open top chambers (OTC) subjected to two different CO2 concentrations i.e. ambient (400 ppm) and elevated (550 ± 25 ppm) and also two different temperature levels i.e. ambient and elevated (+2°C). Nitrogen (N) was applied in five doses i.e., 0%, 75%, 100% and 125% of recommended N dose. Elevated CO2 increased panicle number in rice which was further increased with increase in N doses. High temperature significantly decreased grain number per panicle but elevated CO2 level was able to increase this yield attribute. Spikelet sterility increased in high temperature treatment (18.9%) due to poor grain filling than chamber control treatment (12.4%). But more biomass accumulation resulted in more grain filling and less spikelet sterility under elevated CO2 level. The study showed thatelevated CO2 level will be able to alleviate the negative effect of high temperature on certain yield attributes in rice.
