| When to plant | 30 Jun 2027 – 10 Jul 2027 opens in 39 weeks | 28 Oct 2026 – 17 Nov 2026 |
| Expected harvest | 0.7–0.8 t/ha | about 1.5 t/ha |
| Harvest | From 28 Sep 2027 to 17 Nov 2027, depending on the planting date | |
| Ready to harvest | 90–130 days after planting | |
| Work it takes | 65–129 days per hectare, by hand | |
| Rain meets its needs | 62% | |
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 10 Jul 2027. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Kosti yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 10 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kosti
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 96% |
For sesame in Kosti, rain and temperature is the tightest of the three at 96%. This one is fixed. It is why the planting window above is where it is — hitting those dates is the whole of your control here.
The 2027 season in Kosti
| When the rains are expected | July 2027 to September 2027 |
|---|---|
| Rain in a typical year | About 261 mm |
| This season's rain | Rain close to usual — plan around about 261 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.8 °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 | too dry for rain-fed cropping without irrigation, warm all year, so nothing but rain ends the season |
| Ground this covers | One kind of ground throughout. |

Limited water holds back about 40% of yield here.
What sesame needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 7.5 |
| Rain it needs | About 300–600 mm across the season |
| Spacing | 37 cm between rows, 7 cm between plants |
| Feed it most with | nitrogen, phosphorus and boron |
What it takes to grow sesame in Kosti
| Planting material | About 265,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 38 kg per hectare |
| Phosphate (P₂O₅) | About 10 kg per hectare |
| Potash (K₂O) | About 35 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |
| Hand work | 65–129 days per hectare, by hand |
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.
