| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant (establish) | 21 Sep 2026 – 24 Feb 2027 open now | 1 Jan 2026 – 31 Dec 2026 |
| Expected harvest | about 8.9 t/ha | same |
| Work it takes | 77–175 days per hectare, by hand | |
| Rain meets its needs | 98% | |
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 12 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Nyanza 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 24 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Nyanza
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For oil palm in Nyanza, 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 Nyanza
| When the rains are expected | August 2026 to July 2027 |
|---|---|
| Rain in a typical year | About 981 mm |
| This season's rain | Leaning wet — January, February, 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 +1.2 °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 49% of this area. |

What it takes to grow oil palm in Nyanza
| Planting material | About 143 plants per hectare |
|---|---|
| Nitrogen (N) | About 67 kg per hectare |
| Phosphate (P₂O₅) | About 20 kg per hectare |
| Potash (K₂O) | About 93 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 | 77–175 days per hectare, by hand |
These are the nutrients a oil palm 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.
