When to plant Green gram in Tobruk
East, Libya
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 May 2027 – 20 Jul 2027 opens in 33 weeks |
| Expected harvest | about 2.0 t/ha |
| Harvest | From 20 Jul 2027 to 18 Oct 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 May 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Tobruk is close to normal, so these dates match the pattern the area usually follows.
Planting after 20 Jul 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.

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 Tobruk
| Nitrogen (N) | About 80 kg per hectare — the crop fixes most of this itself; inoculated seed matters more than a bag |
|---|---|
| Phosphate (P₂O₅) | About 20 kg per hectare |
| Potash (K₂O) | About 36 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.
