| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 1 May 2027 – 21 May 2027 opens in 30 weeks | 21 May 2027 – 20 Jul 2027 |
| Expected harvest | about 2.3 t/ha | about 3.5 t/ha |
| Harvest | From 30 Jul 2027 to 28 Sep 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 | 92% | |
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 21 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Magharibi is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Magharibi
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For sunflower in Magharibi, the lie of the land is the tightest of the three at 88%. 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 sunflower in Magharibi
| Planting material | About 50,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 103 kg per hectare |
| Phosphate (P₂O₅) | About 46 kg per hectare |
| Potash (K₂O) | About 184 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.
