When to plant Pigeon pea in Korogwe
Tanga, 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) | 1 Feb 2027 – 21 Feb 2027 opens in 18 weeks | 8 Oct 2026 – 28 Oct 2026 |
| Expected harvest | about 1.8 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 | 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 21 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Korogwe leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 21 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Korogwe
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For pigeon pea in Korogwe, the lie of the land is the tightest of the three at 60%. 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 Korogwe
| When the rains are expected | January 2026 to December 2026 |
|---|---|
| Rain in a typical year | About 1,282 mm |
| This season's rain | Leaning wet — October, 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 +0.9 °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 | 4 kinds of ground. The season below is the largest that farms — about 26% of this area. |
| 26% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 357 growing days · about 1,180 mm · January to January |
|---|---|
| 18% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 205 growing days · about 680 mm · February to June |
| 17% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 158 growing days · about 530 mm · February to June |
| 13% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 245 growing days · about 780 mm · September to July |

What it takes to grow pigeon pea in Korogwe
| Planting material | About 75,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 108 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
| Phosphate (P₂O₅) | About 22 kg per hectare |
| Potash (K₂O) | About 45 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.
