Garissa, Kenya
Known here as mnavu · mnafu

| Fit | Favourable |
|---|---|
| When to plant | 1 May 2027 – 29 Aug 2027 opens in 30 weeks |
| Expected harvest | about 25.0 t/ha |
| Harvest | From 30 Jun 2027 to 27 Dec 2027, depending on the planting date |
| Ready to harvest | 60–120 days after planting |
| Work it takes | 103–191 days per hectare, by hand |
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 1 May 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 29 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
