When to plant Green gram in Bidjabidjan
Kié-Ntem, Guinea Ecuatorial
Green gram (also called mung bean or ndengu) is a fast, warm-weather bean that goes from seed to harvest in just 60–90 days — quick enough to dodge a dry spell and to slot in after your maize, sorghum or millet.
| Fit | Favourable |
|---|---|
| When to plant | 21 Jan 2026 – 8 Oct 2026 open now |
| Expected harvest | about 1.2 t/ha |
| Harvest | From 22 Mar 2026 to 6 Jan 2027, depending on the planting date |
| Ready to harvest | 60–90 days after planting |
| Work it takes | 60–124 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 21 Jan 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Bidjabidjan 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 8 Oct 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Bidjabidjan
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For green gram in Bidjabidjan, 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 2025 season in Bidjabidjan
| When the rains are expected | January 2025 to December 2025 |
|---|---|
| Rain in a typical year | About 1,719 mm |
| This season's rain | Leaning dry — January, February, September, October, November 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 +0.8 °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 77% of this area. |
| 77% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 365 growing days · about 1,740 mm · January to December |

What it takes to grow green gram in Bidjabidjan
| Nitrogen (N) | About 48 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 12 kg per hectare |
| Potash (K₂O) | About 22 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 | 60–124 days per hectare, by hand |
These are the nutrients a green gram 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.
