Known here as haricot mungo · ambérique

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 Jul 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Sangha is close to normal, so these dates match the pattern the area usually follows.
Planting after 21 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Sangha
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 60% |
For green gram in Sangha, 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 Sangha
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | June 2027 to September 2027 |
| Rain in a typical year | About 423 mm |
| This season's rain | Rain close to usual — plan around about 423 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.9 °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 one short crop, and only if timed to it, 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 94% of this area. |
| 94% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 92 growing days · about 430 mm · June to September |
|---|---|
| 6% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 90 growing days · about 410 mm · June to September |

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 Sangha
| 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.
