Central, Uganda

Eggplant (also called aubergine, brinjal or garden egg) is a bushy, warm-season cousin of tomato, potato and pepper — the nightshade family — grown for its glossy fruit: purple, white or green, round or long.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 21 Jan 2027 – 2 Mar 2027 opens in 16 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 29.2 t/ha | about 46.3 t/ha |
| Harvest | From 21 May 2027 to 29 Aug 2027, depending on the planting date | |
| Ready to harvest | 120–180 days after planting | |
| Work it takes | 125–252 days per hectare, by hand | |
| Rain meets its needs | 88% | |
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 10 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Mukono is close to normal, so these dates match the pattern the area usually follows.
Planting after 2 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Mukono
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For eggplant in Mukono, the lie of the land is the tightest of the three at 76%. 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 2025 season in Mukono
| When the rains are expected | December 2025 to December 2025 |
|---|---|
| Rain in a typical year | About 1,121 mm |
| This season's rain | Rain close to usual — plan around about 1,121 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.8 °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 eggplant in Mukono
| Planting material | About 20,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 88 kg per hectare |
| Phosphate (P₂O₅) | About 25 kg per hectare |
| Potash (K₂O) | About 146 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 | 125–252 days per hectare, by hand |
These are the nutrients a eggplant 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.
