Soybeans through the year
Against the frost risk in Cần Thơ
Why these dates
Sow two weeks after the last frost into warm soil. Varieties are grouped by maturity for a given latitude, and a variety from the wrong group will either flower far too early or fail to finish at all - this matters more with soybeans than with almost any other crop.
No frost tolerance. Killed at 0C at both ends of the season.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Soybeans are timed for direct sowing 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Cần Thơ.
