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 24 Oct 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Kartala is close to normal, so these dates match the pattern the area usually follows.
Planting after 19 Dec 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Kartala
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For maize in Kartala, the lie of the land is the tightest of the three at 76%. 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 2026 season in Kartala
| When the rains are expected | September 2026 to September 2026 |
|---|---|
| Rain in a typical year | About 1,816 mm |
| This season's rain | Rain close to usual — plan around about 1,816 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +0.7 °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 a long crop, or two in a year, warm all year, so nothing but rain ends the season |
| Ground this covers | This area is smaller than the climate grid can resolve, so it reads as one kind of ground. |
| 67% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 340 growing days · about 1,830 mm · September to September |
|---|---|
| 33% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 337 growing days · about 1,820 mm · September to September |

What it takes to grow maize in Kartala
| Planting material | About 53,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 86 kg per hectare |
| Phosphate (P₂O₅) | About 43 kg per hectare |
| Potash (K₂O) | About 32 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. |
| Hand work | 82–165 days per hectare, by hand |
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.
