The response of Brassica juncea var. Bio‐183‐92 to elevated CO 2 under increased nitrogen treatment was studied. There was an interactive effect of CO 2 and nitrogen nutrition, indicating that, on the addition of more nitrogen, the plants sustained the positive effect of CO 2 enrichment by utilizing additional carbohydrates for the development of new sinks. Excess carbohydrate enables plants to be flexible and responsive to additional nitrogen application to sustain the CO 2 enrichment effect.
