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 | 9 Aug 2026 – 1 May 2027 open now | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 1.5 t/ha | about 2.0 t/ha |
| Harvest | From 8 Oct 2026 to 30 Jul 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 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Ngoko 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 1 May 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Ngoko
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For green gram in Ngoko, the lie of the land is the tightest of the three at 88%. 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.

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 |

What it takes to grow green gram in Ngoko
| Nitrogen (N) | About 60 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 15 kg per hectare |
| Potash (K₂O) | About 27 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.
