Sidama, Ethiopia
Known here as selit
Sesame — also called simsim or benniseed — is a tough, upright oilseed that grows from knee to shoulder height and gives a seed that is about half oil.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 18 Jan 2027 – 19 Mar 2027 opens in 16 weeks | 1 Jan 2026 – 30 Sep 2026 |
| Expected harvest | about 0.6 t/ha | same |
| Harvest | From 18 Apr 2027 to 27 Jul 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 | 88% | |
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 17 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Southern 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 19 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Southern
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For sesame in Southern, the lie of the land is the tightest of the three at 60%. 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.
The 2026 season in Southern
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,455 mm |
| This season's rain | Leaning wet — February, October, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| 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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 45% of this area. |
| 45% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 319 growing days · about 1,500 mm · February to December |
|---|---|
| 41% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 316 growing days · about 1,360 mm · February to December |
| 7% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 292 growing days · about 1,080 mm · February to December |
| 4% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 270 growing days · about 910 mm · March to December |

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 Southern
| Planting material | About 265,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 33 kg per hectare |
| Phosphate (P₂O₅) | About 9 kg per hectare |
| Potash (K₂O) | About 30 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.
