| Expected harvest | 1.1–1.4 t/ha | about 2.1 t/ha |
| Harvest | From 27 Jan 2027 to 27 Apr 2027, depending on the planting date | |
| Ready to harvest | 60–120 days after planting | |
| Work it takes | 50–105 days per hectare, by hand | |
| Rain meets its needs | 63% | |
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 18 Dec 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ngaka Modiri Molema 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 28 Dec 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ngaka Modiri Molema
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For cowpea in Ngaka Modiri Molema, the lie of the land is the tightest of the three at 88%. 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 2026/27 season in Ngaka Modiri Molema
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | December 2026 to April 2027 |
| Rain in a typical year | About 487 mm |
| This season's rain | Leaning dry — January, February 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 +2.3 °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, with a cool spell that slows winter growth |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 62% of this area. |
| 62% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 144 growing days · about 530 mm · November to April |
|---|---|
| 24% | too dry for rain-fed cropping without irrigation; warm, with a cool spell that slows winter growth no rain-fed season · about 440 mm |
| 14% | enough rain for one short crop, and only if timed to it; warm, with a cool spell that slows winter growth 169 growing days · about 570 mm · November to April |

| Soil it likes | well-drained sand, sandy loam or loam soil |

What it takes to grow cowpea in Ngaka Modiri Molema
| Planting material | About 90,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 66 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 13 kg per hectare |
| Potash (K₂O) | About 24 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. Skip the nitrogen top dressing; inoculated seed does that job. |
| Hand work | 50–105 days per hectare, by hand |
These are the nutrients a cowpea 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.
