A High-Yielding Rice Cultivar "Takanari" Shows No N Constraints on CO₂ Fertilization.

ABSTRACT: Enhancing crop yield response to elevated CO₂ concentrations (E-[CO₂]) is an important adaptation measure to climate change. A high-yielding indica rice cultivar "Takanari" has recently been identified as a potential candidate for high productivity in E-[CO₂] resulting from its large sink and source capacities. To fully utilize these traits, nitrogen should play a major role, but it is unknown how N levels influence the yield response of Takanari to E-[CO₂]. We therefore compared grain yield and quality of Takanari with those of Koshihikari, a standard japonica cultivar, in response to Free-Air CO₂ enrichment (FACE, +200 μmol mol^-1) under three N levels (0, 8, and 12 g m^-2) over three seasons. The biomass of both
