| Fit | Favourable | |
| When to plant | 15 Sep 2026 – 14 Nov 2026 open now | 10 Jun 2026 – 28 Oct 2026 |
| Expected harvest | about 0.7 t/ha | same |
| Harvest | From 14 Dec 2026 to 24 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 15 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Gisuru 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 14 Nov 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Gisuru
| Rain and temperature | 76% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For sesame in Gisuru, 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 2026/27 season in Gisuru
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to June 2027 |
| Rain in a typical year | About 911 mm |
| This season's rain | Leaning wet — January, 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 +1.0 °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 | 4 kinds of ground. The season below is the largest that farms — about 62% of this area. |
| 62% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 268 growing days · about 930 mm · September to June |

| 19% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 274 growing days · about 980 mm · September to June |
| 14% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 271 growing days · about 950 mm · September to June |

What it takes to grow sesame in Gisuru
| 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.
