Simultaneous increase of (CO2) and temperature causing significant changes in rice crop growth and productivity, but limited studies has been done in past to examine the interactive effect of these two key variables on the incidence of brown spot and sheath blight of rice. Thus, an experiment was conducted at ICAR Research Complex for Eastern Region, Patna, by growing rice genotypes (Rajendra bhagwati, IR83376-B-B-24-2, IR 64 and IR84895-B-127-CRA-5-1-1) inside open top chambers (OTCs) and open field condition with two levels of carbon dioxide (ambient and elevated; 500±25 ppm) and temperature (ambient and ambient+2°C) during kharif season of 2016 in order to determine their simultaneous effect on incidence of brown spot and sheath blight. | Interactive effect of elevated CO2 and temperature on the incidence of brown spot and sheath blight of rice Oryza sativa L.
