When to plant Green gram in Halaba
Central Ethiopia, Ethiopia
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 3 Feb 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Halaba is close to normal, so these dates match the pattern the area usually follows.
Planting after 19 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

|---|---|
| The soil | 76% |
| The lie of the land | 88% |

The 2027 season in Halaba
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | March 2027 to November 2027 |
| Rain in a typical year | About 898 mm |
| This season's rain | Rain close to usual — plan around about 898 mm falling roughly when it always does |
| This season's heat | Hotter than usual — about +1.4 °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 full main crop, warm all year, so nothing but rain ends the season |
| Ground this covers | 3 kinds of ground. The season below is the largest that farms — about 70% of this area. |
| 70% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 262 growing days · about 960 mm · March to November |
|---|---|
| 24% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 271 growing days · about 1,000 mm · February to November |
| 7% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 195 growing days · about 780 mm · March to October |

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 Halaba
| 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.
