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 10 Jun 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Hamma is close to normal, so these dates match the pattern the area usually follows.
Planting after 10 Jun 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Hamma
| Rain and temperature | 88% |
|---|---|
| The soil | 76% |
| The lie of the land | 30% |
For maize in Hamma, 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 maize in Hamma
| Planting material | About 53,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 54 kg per hectare |
| Phosphate (P₂O₅) | About 27 kg per hectare |
| Potash (K₂O) | About 20 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 maize 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.
