| When to plant | 6 Oct 2026 – 4 Feb 2027 opens in 1 week | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.2 t/ha | same |
| Harvest | From 4 Jan 2027 to 14 Jun 2027, depending on the planting date | |

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 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Kilombero is close to normal, so these dates match the pattern the area usually follows.
Planting after 4 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Kilombero
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | November 2026 to July 2027 |
| Rain in a typical year | About 1,422 mm |
| This season's rain | Rain close to usual — plan around about 1,422 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.4 °C over the growing months. Heat makes the same rain do less, so a dry spell bites sooner: do not plant late, and shade or mulch what you can. |
| What that supports | enough rain for one full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | One kind of ground throughout. |

| Planting material | About 265,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 66 kg per hectare |
| Phosphate (P₂O₅) | About 18 kg per hectare |

These are the nutrients a sesame 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.
