When to plant Egusi melon in Kusini Unguja
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 | 18 Sep 2026 – 28 Oct 2026 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.2 t/ha | same |
| Harvest | From 17 Dec 2026 to 27 Mar 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-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 8 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's outlook for Kusini Unguja 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 28 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kusini Unguja
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For egusi melon in Kusini Unguja, the lie of the land is the tightest of the three at 88%. 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 Kusini Unguja
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to July 2027 |
| Rain in a typical year | About 1,408 mm in a typical farming district |
| Across its districts | From about 1,408 mm in the driest of 2 districts to about 1,631 mm in the wettest |
| This season's rain | Leaning wet — 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 +1.1 °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 one typical farming district's, not a figure for the whole of this area. |
| 48% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 325 growing days · about 1,510 mm · August to August |
|---|---|

| 3% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 303 growing days · about 1,460 mm · October to August |

What it takes to grow egusi melon in Kusini Unguja
| Nitrogen (N) | About 42 kg per hectare |
|---|---|
| Phosphate (P₂O₅) | About 14 kg per hectare |
| Potash (K₂O) | About 14 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.
