When to plant Chickpea in Tanga
United Republic of Tanzania
Known here as dengu
Chickpea is a knee-high, branching legume grown for its round, protein-rich seeds — the pea behind roasted snacks, stews and hummus.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Moderate | |
| When to plant | 1 May 2027 – 21 May 2027 opens in 30 weeks | 1 Jan 2026 – 30 Sep 2026 |
| Expected harvest | about 0.8 t/ha | same |
| Harvest | From 30 Jul 2027 to 18 Oct 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 56–114 days per hectare, by hand | |
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 1 May 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Tanga 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 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Tanga
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For chickpea in Tanga, the lie of the land is the tightest of the three at 30%. 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 Tanga
| When the rains are expected | January 2026 to January 2026 |
|---|---|
| Rain in a typical year | About 1,144 mm in a typical farming district |
| Across its districts | From about 565 mm in the driest of 10 districts to about 1,282 mm in the wettest |
| Rainy seasons, district by district | Of 10 districts: one rainy season in 3 and two rainy seasons in 1 |
| This season's rain | Leaning wet — make sure water can drain off the field. |
| This season's heat | Hotter than usual — about +1.1 °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 one typical farming district's, not a figure for the whole of this area. |
| 30% | 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 1,100 mm · January to January |
|---|---|
| 25% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 287 growing days · about 890 mm · September to July |
| 18% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 250 growing days · about 770 mm · October to July |
| 11% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 198 growing days · about 610 mm · February to June |

Sloping ground holds back about 65% of yield here.
What chickpea needs to grow here
| Soil it likes | well-drained loam, clay loam or clay soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 8.0 |
| Spacing | 30 cm between rows, 10 cm between plants |
| Feed it most with | phosphorus |
What it takes to grow chickpea in Tanga
| Nitrogen (N) | About 32 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 4 kg per hectare |
| Potash (K₂O) | About 12 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 | 56–114 days per hectare, by hand |
These are the nutrients a chickpea 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.
