When to plant Groundnut in Uganda
Known here as karanga · njugu
Groundnut (peanut) is a low, leafy legume that does something no other crop in your field does: it flowers above the ground, but then each fertilised flower sends a little stalk — a peg — down into the soil, and the nut grows and fills underground.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 9 Aug 2026 – 21 Jan 2027 open now | 30 Jun 2026 – 21 Jan 2027 |
| Expected harvest | about 2.3 t/ha | about 3.2 t/ha |
| Harvest | From 7 Nov 2026 to 20 Jun 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 71–126 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 18 Sep 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Uganda 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 21 Jan 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Uganda
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 96% |
For groundnut in Uganda, rain and temperature is the tightest of the three at 88%. This one is fixed. It is why the planting window above is where it is — hitting those dates is the whole of your control here.
The 2026/27 season in Uganda
| When the rains are expected | February 2026 to January 2027 |
|---|---|
| Rain in a typical year | About 1,366 mm in a typical farming district |
| Across its districts | From about 627 mm in the driest of 135 districts to about 1,738 mm in the wettest |
| Rainy seasons, district by district | Of 135 districts: one rainy season in 65 and two rainy seasons in 11 |
| 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 +1.3 °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 | 5 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 32% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 341 growing days · about 1,110 mm · February to December |
|---|---|
| 29% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 282 growing days · about 1,050 mm · March to December |
| 22% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 249 growing days · about 930 mm · March to November |
| 6% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 249 growing days · about 700 mm · August to January |
| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 343 growing days · about 1,020 mm · July to June |

Temperature holds back about 20% of yield here.
What groundnut needs to grow here
| Soil it likes | well-drained sandy loam or sandy soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.9 and 7.0 |
| Spacing | 45 cm between rows, 9 cm between plants |
| Feed it most with | phosphorus, potassium and calcium |
What it takes to grow groundnut in Uganda
| Planting material | About 247,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 126 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 23 kg per hectare |
| Potash (K₂O) | About 69 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job. |
| Hand work | 71–126 days per hectare, by hand |
These are the nutrients a groundnut 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.
What to watch for
Grow Groundnut with a plan, not a guess
Everything above describes Uganda as a whole — your own soil, slope and rainfall will shift the dates. The Divisi app works them out for your field, and dates each job that follows.

Frequently asked questions
Will groundnut grow well in Uganda?
Uganda rates as favourable for groundnut.
When should I plant groundnut in Uganda?
Typically 9 Aug 2026 to 21 Jan 2027, forecast-adjusted.
Is this exact for my own field?
No — these are readings taken across Uganda, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
