Rain-fed. These dates are worked out from each place's own rainfall, for a field watered by the season — with irrigation a window can open earlier, close later, or come round more than once a year. Check your own field under What grows, or get the Divisi app for a calendar dated to your farm.
If you only get one chance to plant, aim for around 7 Oct 2026. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Birine yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 16 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
