| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 20 Jul 2026 – 17 Nov 2026 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.9 t/ha | about 2.6 t/ha |
| Harvest | From 18 Oct 2026 to 27 Mar 2027, depending on the planting date | |
| Ready to harvest | 90–130 days after planting | |
| Work it takes | 74–155 days per hectare, by hand | |
| Rain meets its needs | 91% | |
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 20 Jul 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Owando leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
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 Owando
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For sunflower in Owando, the lie of the land is the tightest of the three at 76%. 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 Owando
| When the rains are expected | July 2026 to July 2026 |
|---|---|
| Rain in a typical year | About 1,343 mm |
| This season's rain | Leaning dry. Plant at the early end of the window and favour quicker, more drought-tolerant crops. |
| 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 | One kind of ground throughout. |

What it takes to grow sunflower in Owando
| Planting material | About 50,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 86 kg per hectare |
| Phosphate (P₂O₅) | About 38 kg per hectare |
| Potash (K₂O) | About 152 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 | 74–155 days per hectare, by hand |
These are the nutrients a sunflower 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.
