Abstract

To study interactions between nutrient supply and increased CO2 concentration in sugarbeet, plants were grown in pots for 4 months at ambient and doubled CO2 concentration and different levels of N, P or K. Doubling of ambient CO2 resulted in a moderate increase in total yield ( 24%) and beet yield ( 34%), however this CO2 effect disappeared with increasing nutrient shortage (in particular nitrogen). CO2 doubling did not result in significant changes in the minimum nutrient concentrations in leaves and beets.
