Abstract

An experiment was carried out during the kharif season of year 2013 inside Temperature Gradient Tunnel (TGT) of Centre for Environment Science and Climate Resilient Agriculture (CESCRA), at IARI farm to study impact of elevated temperature on the growth and yield responses of rice crop under four N levels. Results showed that grain and biomass yield of rice had decreased significantly with rise in temperature inside the TGT. With recommended N dose, yield reduction of rice was 37 per cent with rise in temperature to 3.9ºC over ambient air condition but application of 125 per cent N can prevent the yield loss by 6per cent as compared to 100 per cent recommended N treatment. Yield parameters Spikelet sterility of rice did increase with increase in temperature.
