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 Jul 2027. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Bouza yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 8 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2027 season in Bouza
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | July 2027 to September 2027 |
| Rain in a typical year | About 376 mm |
| This season's rain | Rain close to usual — plan around about 376 mm falling roughly when it always does |
| 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 short crop, and only if timed to it, warm all year, so nothing but rain ends the season |
| Ground this covers | 2 kinds of ground. The season below is the largest that farms — about 49% of this area. |
| 50% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 330 mm · July to September |
|---|---|
| 49% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 77 growing days · about 380 mm · June to September |

What it takes to grow tomato in Bouza
| Planting material | About 33,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 60 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. |

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.
