| Measure | Rain-fed | With irrigation |

| Fit | Favourable | |
| When to plant | 9 Mar 2027 – 21 Jun 2027 opens in 23 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | 2.1–2.3 t/ha | about 3.2 t/ha |
| Harvest | From 7 Jun 2027 to 29 Oct 2027, depending on the planting date | |

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 22 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Kween is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kween
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 88% |
For sunflower in Kween, the soil is the tightest of the three at 76%. This is the one you can actually move. Lime raises a sour soil, manure and compost lift what it holds, and both work within a season or two — money spent here changes the answer.
The 2026 season in Kween
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2026 to December 2026 |
| Rain in a typical year | About 995 mm |
| This season's rain | Rain close to usual — plan around about 995 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.5 °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 51% of this area. |
| 51% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 277 growing days · about 1,010 mm · March to December |
