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 27 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Fafi leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 6 Apr 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

What it takes to grow maize in Fafi

|---|---|
| Nitrogen (N) | About 48 kg per hectare |
| Phosphate (P₂O₅) | About 24 kg per hectare |
| Potash (K₂O) | About 18 kg per hectare |

These are the nutrients a maize crop of that size carries off the field. What you actually apply depends on what your soil already holds — which is what a soil test, or the app's field records, tell you.
