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 2 Dec 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Oichili-Dimani is close to normal, so these dates match the pattern the area usually follows.
Planting after 1 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
