When to plant Tomato in Guji
Oromia, Ethiopia
Known here as timatim
Tomato is the number-one cash vegetable across sub-Saharan Africa — and one of the most demanding.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 14 Jan 2027 – 13 Jul 2027 opens in 15 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 25.4 t/ha | about 47.9 t/ha |
| Harvest | From 14 Apr 2027 to 10 Dec 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 81–160 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 30 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Guji 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 13 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Guji
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 45% |
For tomato in Guji, the lie of the land is the tightest of the three at 45%. 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 season in Guji
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | July 2026 to December 2026 |
| Rain in a typical year | About 935 mm |
| This season's rain | Leaning wet — October, 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 +1.4 °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 30% of this area. |
| 30% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 222 growing days · about 840 mm · August to December |
|---|---|
| 15% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 319 growing days · about 1,610 mm · February to December |
| 14% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 310 growing days · about 1,250 mm · February to December |
| 12% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 161 growing days · about 630 mm · March to June |

Sloping ground holds back about 35% of yield here.
What tomato needs to grow here
| Soil it likes | well-drained sandy loam, loam or clay loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 6.8 |
| Spacing | 80 cm between rows, 40 cm between plants |

What it takes to grow tomato in Guji
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 66 kg per hectare |
| Phosphate (P₂O₅) | About 18 kg per hectare |
| Potash (K₂O) | About 94 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 | 81–160 days per hectare, by hand |
These are the nutrients a tomato 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.
