SUPPORTING INFORMATION
Supplementary Table S1 Experimental design and fertilizer conditions in each experimental site.
The experimental plots were arranged in a randomized complete block design in Joetsu, Los Baños, Nay Pyi Taw, and Coimbatore.
60 panicles that were randomly chosen from the bulk of panicles were used for the determination of yield and yield components.
Supplementary Table S2 Time to reach the peak (FOT50) and end (FOT90) of flower opening in Nay Pyi Taw.
***Significant at 0.1% level by ANOVA.
Dates of observation were 3–6 April in Crop 1 of 2015, 28–30 April and 1 May in Crop 1 of 2017, 16–19 May in Crop 2 of 2017, 21–24 April in Crop 1 of 2018, 16–19 May 12–14 in Crop 2 of 2018, 4–7 April for IR64 and 8–11 April for IR64+qEMF3 in Crop 1 of 2019, and 3–6 May for IR64 and 8–11 May for IR64+qEMF3 in Crop 2 of 2019.
FOT50 and FOT90 are expressed as hours after dawn. Average of maximum temperature during heading is shown in Table 5.

Measurement was conducted by individual 14 plants except for Days to heading.
**, ***Significant at the 10%, 1%, and 0.1% level, respectively, by t -test; ns: not significant.
