When to plant Green gram in Ribeira Brava
Cabo Verde
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.

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 2 Aug 2027. That is the point in the window where the rains are most reliably established.
No seasonal forecast reaches Ribeira Brava yet, so these dates follow the rains it usually gets rather than this year's.
Planting after 22 Aug 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ribeira Brava
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For green gram in Ribeira Brava, 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 2027 season in Ribeira Brava
| When the rains are expected | August 2027 to October 2027 |
|---|---|
| Rain in a typical year | About 290 mm in a typical farming district |
| Across its districts | From about 277 mm in the driest of 2 districts to about 290 mm in the wettest |
| This season's rain | Rain close to usual — plan around about 290 mm falling roughly when it always does |
| What that supports | too dry for rain-fed cropping without irrigation, warm all year, so nothing but rain ends the season |
| Ground this covers | 3 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |

What green gram needs to grow here
| Soil it likes | well-drained loam or sandy loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 7.5 |
| Spacing | 37 cm between rows, 10 cm between plants |
| Feed it most with | phosphorus |
What it takes to grow green gram in Ribeira Brava
| Nitrogen (N) | About 36 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 9 kg per hectare |
| Potash (K₂O) | About 16 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.
