When to plant Sorghum in Rubanda
Western, Uganda
Known here as mtama
Sorghum (Sorghum bicolor — mapfunde, mtama, amabele, mapira, dawa, mashilla) is the toughest of the grain cereals: a tall, C4 grass that keeps standing and yields when heat and dry spells have already beaten maize.
| Measure | Rain-fed | With irrigation |
|---|---|---|
| Fit | Moderate | |
| When to plant | 10 Jul 2026 – 1 Dec 2026 open now | 21 May 2026 – 7 Dec 2026 |
| Expected harvest | about 1.2 t/ha | same |
| Harvest | From 8 Oct 2026 to 20 Apr 2027, depending on the planting date | |
| Ready to harvest | 90–140 days after planting | |
| Work it takes | 92–168 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 27 Aug 2026. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Rubanda is close to normal, so these dates match the pattern the area usually follows.
Planting after 1 Dec 2026 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Rubanda
| Rain and temperature | 88% |
|---|---|
| The soil | 96% |
| The lie of the land | 30% |
For sorghum in Rubanda, the lie of the land is the tightest of the three at 30%. 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 season in Rubanda
| When the rains are expected | July 2026 to July 2026 |
|---|---|
| Rain in a typical year | About 1,045 mm |
| This season's rain | Rain close to usual — plan around about 1,045 mm falling roughly when it always does |
| What that supports | enough rain for a long crop, or two in a year, 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 87% of this area. |
| 87% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 350 growing days · about 1,020 mm · July to July |
|---|---|
| 13% | enough rain for a long crop, or two in a year; warm all year, so nothing but rain ends the season 350 growing days · about 1,040 mm · July to July |

What sorghum needs to grow here
| Soil it likes | sandy loam, loam, clay loam or clay |
|---|---|
| Soil sourness (pH) | Happiest between pH 6.0 and 7.5 |
| Rain it needs | About 450–650 mm across the season |
| Spacing | 70 cm between rows, 15 cm between plants |
| Feed it most with | nitrogen, phosphorus, zinc and sulphur |
What it takes to grow sorghum in Rubanda
| Planting material | About 100,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 5 kg per hectare |
| Phosphate (P₂O₅) | About 2 kg per hectare |
| Potash (K₂O) | About 6 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 | 92–168 days per hectare, by hand |
These are the nutrients a sorghum 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.
