Abstract: The impact of rising concentration of atmospheric CO2 on the productivity of crop plants was studied using Open Top Chamber (OTC) and Free Air CO2 Enrichment (FACE) technologies, established under National Fellow Project at Indian Agricultural Research Institute, New Delhi. These investigations led to the establishment of South Asian CO2 research network of Bangladesh, Nepal, Sri Lanka, Pakistan and India to study the effect of elevated level of CO2 on the productivity of cereals, pulses and oil seeds. Indian studies revealed that elevated CO2 significantly ameliorated the effect of adverse drought stress in Brassica species. It also demonstrated the possibility of transferring CO2 responsive characters in Brassica hybrids. The data generated from these investigations may possibly help in developing plant type and identifying a suitable crop management system for future high CO2 environment.
