Abstract:

Anthropogenic activities in few decades past have increased the concentration of the atmospheric greenhouse gases (GHGs) which leads to climate change. This changing climate will certainly have impact on agricultural production. A study was carried out during the kharif season of year 2017 inside the open top chamber (OTCs) in IARI farm, New Delhi to quantify the interactive effect of elevated CO2 and temperature on growth of rice crop. Rice crop was grown in crates under two different CO2 levels: ambient (400 ppm) and elevated (550±25 ppm) and with two temperature levels: ambient and elevated (+2°C). Growth of rice increased in elevated CO2 treatment while it decreased under high temperature condition. This was observed in terms of changes in tiller number, straw weight and root weight of the crop. Straw weight of rice reduced from 44.7 g hill-1 to 52.1 g hill-1in high temperature treatment. But increase in CO2 concentration significantly increased straw weight of the crop. The study showed that increased CO2 concentration was able to compensate the loss due to enhance growth of rice crop under high CO2 condition.
