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 19 Apr 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for South Gondar 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 9 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in South Gondar
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For yam in South Gondar, the lie of the land is the tightest of the three at 30%. 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 2027 season in South Gondar
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | May 2027 to October 2027 |
| Rain in a typical year | About 872 mm |
| This season's rain | Leaning wet — October 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 +1.2 °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 | 4 kinds of ground. The season below is the largest that farms — about 47% of this area. |
| 47% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 173 growing days · about 950 mm · May to October |
|---|---|
| 26% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 191 growing days · about 1,140 mm · April to October |
| 18% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 207 growing days · about 1,170 mm · April to November |
| 4% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 144 growing days · about 800 mm · May to October |

What yam needs to grow here
| Soil it likes | well-drained sandy loam or loam soil |

What it takes to grow yam in South Gondar
| Planting material | About 10,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 19 kg per hectare |
| Phosphate (P₂O₅) | About 6 kg per hectare |
| Potash (K₂O) | About 29 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 yam 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.
