| Bearing cycle | 240–730 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |

| Rain meets its needs | 97% | |
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 5 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Umuahia South 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 25 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Umuahia South
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 76% |
For cassava in Umuahia South, 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 Umuahia South
| When the rains are expected | February 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 2,185 mm |
| This season's rain | Leaning dry — February, September, October and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +0.6 °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 | 2 kinds of ground. The season below is the largest that farms — about 93% of this area. |
| 93% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 316 growing days · about 2,170 mm · February to December |
|---|---|
| 7% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 317 growing days · about 2,180 mm · February to December |

|---|---|
| Nitrogen (N) | About 141 kg per hectare |
