Evaluation of the effects of elevated CO₂ concentrations on the growth of cassava storage roots by destructive harvests and ground penetrating radar scanning approaches.

ABSTRACT: Cassava (Manihot esculenta Crantz) production will need to be improved to meet future food demands in Sub-Saharan Africa. The selection of high-yielding cassava cultivars requires a better understanding of storage root development. Additionally, since future production will happen under increasing atmospheric CO₂ concentrations ([CO₂ ]), cultivar selection should include responsiveness to elevated [CO₂ ]. Five farmer-preferred African cassava cultivars were grown for three and a half months in a Free Air CO₂ Enrichment experiment in central Illinois. Compared to ambient [CO₂ ] (~400 ppm), cassava storage roots grown under elevated [CO₂ ] (~600 ppm) had a higher biomass with some cultivars having lower storage root water cont
