When to plant Egusi melon in Ngorongoro
Arusha, United Republic of Tanzania
Egusi is a trailing melon vine — a cousin of the watermelon — but you do not grow it for the fruit.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 17 Oct 2026 – 14 Feb 2027 opens in 2 weeks | 1 Jan 2026 – 30 Sep 2026 |
| Expected harvest | 0.7–0.9 t/ha | same |
| Harvest | From 15 Jan 2027 to 14 Jul 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 50–108 days per hectare, by hand | |
| Rain meets its needs | 68% | |
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 14 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Ngorongoro 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 14 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Ngorongoro
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to May 2027 |
| Rain in a typical year | About 689 mm |
| This season's rain | Leaning wet — January, 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 +1.0 °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 one full main crop, 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 61% of this area. |
| 61% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 212 growing days · about 670 mm · October to May |
|---|---|
| 14% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 166 growing days · about 440 mm · November to April |
| 10% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 350 mm |
| 5% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 280 growing days · about 960 mm · October to July |

Limited water holds back about 30% of yield here.
What egusi melon needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |

What it takes to grow egusi melon in Ngorongoro
| Nitrogen (N) | About 28 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 10 kg per hectare |
| Potash (K₂O) | About 10 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 | 50–108 days per hectare, by hand |
These are the nutrients a egusi melon 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.
