Fig 2. Yield trend patterns of four crops in 1981–2008 calculated using the two datasets at 0.083° resolution.

Those presented by Ray et al. [4] are for the period 1961–2008 and are used as a reference (Ref. R12). The data were divided into the six yield trend patterns and color coded. The gray shaded area indicates that a crop of interest was harvested but yield data are lacking.
