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 2 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sao Nicolau Tolentino leans dry, so these dates sit later than the long-run average. Planting on the date you are used to risks germinating into a false start and having to replant.
Planting after 30 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Sao Nicolau Tolentino
| Rain and temperature | 96% |

For yam in Sao Nicolau Tolentino, 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.

What it takes to grow yam in Sao Nicolau Tolentino
| Planting material | About 10,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 34 kg per hectare |
| Phosphate (P₂O₅) | About 10 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.
