When to plant Pigeon pea in Ngorongoro
Arusha, United Republic of Tanzania
Known here as mbaazi
Pigeon pea (red gram) is a hardy, woody bush bean that sends a taproot two metres deep, so it keeps growing and podding long after other crops burn off in the dry.

| Fit | Favourable | |
| When to plant (establish) | 3 Feb 2027 – 23 Feb 2027 opens in 18 weeks | 1 Jan 2027 – 30 Jun 2027 |
| Expected harvest | about 1.1 t/ha | same |
| Bearing cycle | 90–300 days per crop once the plant is established. Planting to the first harvest takes longer than one cycle. | |
| Rain meets its needs | 55% | |
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 3 Feb 2027. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Ngorongoro yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 23 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

The 2026/27 season in Ngorongoro
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to May 2027 |
| Rain in a typical year | About 689 mm |
| This season's rain | Leaning wet — January, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.0 °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 full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 4 kinds of ground. The season below is the largest that farms — about 61% of this area. |
| 61% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 212 growing days · about 670 mm · October to May |
|---|---|
| 14% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 166 growing days · about 440 mm · November to April |
| 10% | too dry for rain-fed cropping without irrigation; warm all year, so nothing but rain ends the season no rain-fed season · about 350 mm |
| 5% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 280 growing days · about 960 mm · October to July |

What it takes to grow pigeon pea in Ngorongoro
| Planting material | About 75,000 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 28 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. |
These are the nutrients a pigeon pea 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.
