When to plant Rice in Plateaux
Haut-Ogooue, Gabon
Rice is a grass that lives on water.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 4 Sep 2026 – 19 Mar 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 4.1 t/ha | about 6.1 t/ha |
| Harvest | From 3 Dec 2026 to 16 Aug 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 69–107 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 22 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Plateaux 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 19 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Plateaux
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For rice in Plateaux, 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 Plateaux
| When the rains are expected | August 2026 to July 2027 |
|---|---|
| Rain in a typical year | About 1,680 mm |
| This season's rain | Leaning dry — September, October, November and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +0.9 °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 | One kind of ground throughout. |

What it takes to grow rice in Plateaux
| Planting material | About 600,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 61 kg per hectare |
| Phosphate (P₂O₅) | About 20 kg per hectare |
| Potash (K₂O) | About 90 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 | 69–107 days per hectare, by hand |
These are the nutrients a rice 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.
