What grows in Butiam
Mara, United Republic of Tanzania
The 2026/27 season in Butiam
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | September 2026 to June 2027 |
| Rain in a typical year | About 818 mm |
| This season's rain | Leaning wet — January, 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 +0.9 °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 | 2 kinds of ground. The season below is the largest that farms — about 87% of this area. |
| 87% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 253 growing days · about 840 mm · September to June |
|---|---|
| 11% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 286 growing days · about 920 mm · September to June |

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.
What grows in Butiam with irrigation
These need water applied — rain alone will not carry them here. The dates are the windows their own water supply allows.

What Divisi would not plant in Butiam
Every crop in the catalogue is scored against this district, not only the ones that work — so the list above is a decision rather than a shortlist. These are the rest, with what ruled each one out.
- Enset Only in patches — clears in part of this area, not across any one zone
- Sugarcane Moderate
- Cabbage Unsuitable — Temperature
- Chickpea Unsuitable — Temperature
- Coconut Unsuitable — Temperature
- Garlic Unsuitable — Temperature
- Ginger Unsuitable — Water
- Oil palm Unsuitable — Water
- Teff Unsuitable — Temperature
Divisi scored 74 crops against this district's own ground; 9 came back without a sowing date.
Plan the season, not just check it
The crops and dates above are read at cells spread across Butiam, and the map colours which kind of ground each part of it is. Your own soil, slope and rainfall will shift the dates — the Divisi app works them out for your field, and dates each job that follows.

Frequently asked questions
What crops grow well in Butiam?
Guava, Lime, Avocado, Cassava, Cotton all rate well in Butiam — scored against its own rainfall, soil and terrain rather than a national average.
When should I plant Guava in Butiam?
In Butiam the window for Guava runs 11 Sep 2026 to 17 Mar 2027.
Is there a farming app that works in Butiam?
Divisi does. It reads Butiam's own rainfall, soil and terrain rather than a national average, so the planting dates and crop shortlist on this page are the same ones the app works out for a field here — then dates each job for that field, and keeps working with no signal.
Is this exact for my own field?
No — these are readings taken across Butiam, not on your field. Soil, slope and rainfall change from one farm to the next. Check your own location to see your own numbers.
