When to plant Irish potato in Manica
Moçambique
Known here as batata
The Irish potato (mbatatisi, ikirayi, viazi mviringo) is a cool-weather crop grown for the tubers that swell underground — it is not a grain, and it is not the same plant as sweet potato.
| Measure | Rain-fed | With irrigation |

| Fit | Favourable | |
| When to plant | 5 Mar 2027 – 25 Mar 2027 opens in 22 weeks | same |
| Expected harvest | about 25.7 t/ha | about 37.3 t/ha |
| Harvest | From 14 May 2027 to 2 Aug 2027, depending on the planting date | |
| Ready to harvest | 70–130 days after planting | |
| Work it takes | 110–185 days per hectare, by hand | |
| Rain meets its needs | 94% | |
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 15 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's rainfall outlook for Manica 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 25 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Manica
| Rain and temperature | 96% |
|---|---|
| The soil | 76% |
| The lie of the land | 60% |
For irish potato in Manica, 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 Manica
| Rainy seasons | One each year — one chance to plant, so timing carries it |
|---|---|
| When the rains are expected | October 2026 to June 2027 |
| Rain in a typical year | About 1,023 mm in a typical farming district |
| Across its districts | From about 630 mm in the driest of 12 districts to about 1,138 mm in the wettest |
| This season's rain | Leaning dry — January, February, November 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 +1.5 °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. |
| 50% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 218 growing days · about 1,060 mm · October to June |
|---|---|
| 48% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 166 growing days · about 750 mm · November to April |

Sloping ground holds back about 20% of yield here.
What irish potato needs to grow here
| Soil it likes | well-drained loam or sandy loam soil |

What it takes to grow irish potato in Manica
| Planting material | About 47,000 plants per hectare |
|---|---|
| Nitrogen (N) | About 85 kg per hectare |
| Phosphate (P₂O₅) | About 26 kg per hectare |
| Potash (K₂O) | About 149 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 | 110–185 days per hectare, by hand |
These are the nutrients a irish potato 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.
