Chickpeas through the year
Against the frost risk in Zhoukou
Why these dates
Sow two weeks before the last frost in a climate with dry summers. Where late summer is wet, sow as early as possible so the pods dry before the rain arrives.
Seedlings tolerate about -4C. Flowers are damaged at -1C, so a late frost during bloom reduces the pod set without killing the plant.
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. Chickpeas are timed for direct sowing 2 weeks before it, and this page simply resolves those offsets against the frost date computed for Zhoukou.
The median frost-free season here is 249 days, against 100 to 130 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
