| Fit | Favourable |
|---|---|
| When to plant | 8 Oct 2026 – 17 Nov 2026 opens in 1 week |
| Expected harvest | about 0.7 t/ha |
| Harvest | From 6 Jan 2027 to 27 Mar 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-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 28 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for West Coast is close to normal, so these dates match the pattern the area usually follows.
Planting after 17 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in West Coast
| Rain and temperature | 76% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For sesame in West Coast, the lie of the land is the tightest of the three at 45%. You cannot flatten it, but you can farm it: plant along the contour rather than up and down, ridge or tie ridges to hold water on the slope, and expect shallower rooting than the crop would manage on flat ground.

What it takes to grow sesame in West Coast
| Planting material | About 265,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 38 kg per hectare |
| Phosphate (P₂O₅) | About 10 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.
