Irish Potato Prices Rise To Ksh3,900 Per 50kg Bag Across Major Kenyan Markets

Anyone buying or selling Irish potatoes right now knows the drill: the price you get depends heavily on where you are and which variety you’re dealing with.

Fresh figures from the National Potato Council of Kenya (NPCK), released on August 28, 2026, confirm just how wide that gap can be, with a kilogram going for anywhere between Ksh53 and Ksh79 depending on the market.

Do the math on a standard 50kg bag, and you’re looking at a range of roughly Ksh2,650 on the low end to nearly Ksh3,950 on the high end.

Mombasa is currently one of the priciest spots, with potatoes fetching Ksh76 a kilo,          pushing a full bag to around Ksh3,800. Over in Eldoret, traders reported Ksh64 per kilogram, or about Ksh3,200 a bag.

Nairobi, meanwhile, sits somewhere in the middle, with prices swinging between Ksh55 and Ksh65 per kilo. That works out to a bag costing anywhere from Ksh2,750 to Ksh3,250, depending on who you’re buying from.

Up in Nakuru, potatoes were going for Ksh68 a kilo, putting a 50kg bag at roughly Ksh3,400. Meru’s Shangi variety was noticeably cheaper, trading between Ksh53 and Ksh57 per kilogram, translating to a bag priced somewhere between Ksh2,650 and Ksh2,850.

Isiolo told a different story altogether. Shangi potatoes there were commanding a steep Ksh71 to Ksh79 per kilo, while the Unica variety came in lower at Ksh61. That’s a bag of Shangi costing between Ksh3,550 and Ksh3,950, against roughly Ksh3,050 for a bag of Unica.

Rounding things off, Kisumu recorded prices of Ksh68 to Ksh73 per kilo, or about Ksh3,400 to Ksh3,650 for a full bag.

The numbers make it clear that Isiolo is currently the most expensive place to buy Shangi potatoes, with a bag touching nearly Ksh4,000 at the top end. Meru sits at the opposite extreme, offering the cheapest Shangi bags on record at around Ksh2,650.

It’s worth keeping in mind that these bag prices aren’t official NPCK quotes; they’re estimates derived from the council’s per-kilogram figures, and actual prices will always shift with variety, quality, and the basic push and pull of supply and demand in each market.

Still, for farmers and traders trying to figure out where to sell or buy, this snapshot from NPCK offers a useful sense of where the country’s potato prices currently stand.
