Fig. 2: Yield performance of potato cultivation in low-yield staple grain crop regions.

Simulated dry yield of switching maize to potato (m–p), switching rice to potato (r–p), and switching wheat to potato (w–p) under potential (PY) (a–c) and rainfed (RY) (d–f) conditions. The histogram on each map shows the average potato yield in these suboptimal regions compared with the yields of three major grain crops. The error bar shows the interannual variation for each crop. The abbreviations corresponding to the provinces can be found in the supplementary Fig. S6. The legend in each map is consistent with (a).
