| Measure | Rain-fed | With irrigation |

| Fit | Favourable | |
| When to plant | 2 Mar 2027 – 12 Mar 2027 opens in 22 weeks | 22 Mar 2027 – 20 Jul 2027 |
| Expected harvest | about 20.4 t/ha | about 35.0 t/ha |
| Harvest | From 31 May 2027 to 9 Aug 2027, depending on the planting date | |
| Ready to harvest | 90–150 days after planting | |
| Work it takes | 70–148 days per hectare, by hand | |
| Rain meets its needs | 81% | |
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 12 Mar 2027. That is the point in the window where the rains are most reliably established.
This season's outlook for Taveta leans wet. Plant at the early end of the window, and make sure water can drain off the field — a wet year does more damage through waterlogging than through the rain itself.
Planting after 12 Mar 2027 leaves the crop short of season: it runs into the dry months before it has finished filling.
What decides this in Taveta
| Rain and temperature | 96% |
|---|---|
| The soil | 96% |
| The lie of the land | 88% |
For sweet potato in Taveta, the lie of the land is the tightest of the three at 88%. 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 Taveta
| Rainy seasons | Two each year — two chances to plant |
|---|---|
| When the rains are expected | February 2026 to June 2026 |
| Rain in a typical year | About 711 mm |
| This season's rain | Leaning wet — February, October, November and December look heavier than usual. Make sure water can drain off the field; a wet year does more damage through waterlogging and disease than through the rain itself. |
| This season's heat | Hotter than usual — about +1.0 °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 50% of this area. |
| 50% | enough rain for one full main crop; warm all year, so nothing but rain ends the season 184 growing days · about 640 mm · February to June |
|---|---|
| 41% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 174 growing days · about 590 mm · February to May |
| 8% | enough rain for one short crop, and only if timed to it; warm all year, so nothing but rain ends the season 159 growing days · about 550 mm · February to June |

|---|---|
| Nitrogen (N) | About 82 kg per hectare |
