Extended Data Fig. 2: The rice CO2 fertilization effect (CFE) as a function of different potential drivers.

From: Rising atmospheric carbon dioxide concentrations increase gaps of rice yields between low- and middle-to-high-income countries

Extended Data Fig. 2

a, Variations of the difference in the corrected Akaike information criterion (ΔAICc) of the most competitive regression models for the impact of rice growing season average temperature (Tair), subspecies, phosphatic fertilizer (P), potash fertilizer (K), plant density (PD) and nitrogen fertilizer (N) on CFE. b, Relative importance of potential drivers regulating the effects of CO2 increase on rice yield.
