When to plant Pearl millet in Betsiboka
Madagascar
Pearl millet (Pennisetum glaucum) is the toughest grain you can grow.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Favourable | |
| When to plant | 25 Oct 2026 – 22 Feb 2027 opens in 3 weeks | 21 Jan 2026 – 1 Jan 2027 |
| Expected harvest | about 2.1 t/ha | same |
| Harvest | From 24 Dec 2026 to 22 Jun 2027, depending on the planting date | |
| Ready to harvest | 60–120 days after planting | |
| Work it takes | 75–150 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 3 Jan 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Betsiboka 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 22 Feb 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Betsiboka
| Rain and temperature | 96% |
|---|---|
| The soil | 88% |
| The lie of the land | 60% |
For pearl millet in Betsiboka, 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 2026/27 season in Betsiboka
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to April 2027 |
| Rain in a typical year | About 1,501 mm in a typical farming district |
| Across its districts | From about 1,501 mm in the driest of 3 districts to about 1,529 mm in the wettest |
| This season's rain | Leaning dry — January, February and December look short of rain. Plant at the early end of the window, favour quicker and more drought-tolerant crops, and keep moisture in the soil: mulch, and weed early. |
| This season's heat | Hotter than usual — about +1.2 °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 | 2 kinds of ground. The season below is one typical farming district's, not a figure for the whole of this area. |
| 57% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 177 growing days · about 1,550 mm · November to April |
|---|---|
| 43% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 183 growing days · about 1,620 mm · October to April |

Sloping ground holds back about 20% of yield here.
What pearl millet needs to grow here
| Soil it likes | well-drained sand or sandy loam soil |
|---|---|
| Soil sourness (pH) | Happiest between pH 5.5 and 7.0 |
| Spacing | 60 cm between rows, 12 cm between plants |
| Feed it most with | nitrogen and phosphorus |
What it takes to grow pearl millet in Betsiboka
| Planting material | About 180,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 56 kg per hectare |
| Phosphate (P₂O₅) | About 45 kg per hectare |
| Potash (K₂O) | About 82 kg per hectare |
| In the shops | A basal compound at planting — Compound D, or an NPK blend — covers the phosphate and potash. A nitrogen top dressing — urea or AN — goes on once the crop is established. |
| Hand work | 75–150 days per hectare, by hand |
These are the nutrients a pearl millet 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.
