Figures from Potato Council show that, for the week ending 18 July, the average weekly price of the crop was £165.90/tonne - compared to £140.32/tonne during the same week last year.
This year's prices have occasionally dipped below last year's but now clearly show a strong difference. Figures also show that growers are continuing to keep on top of their crops, with harvesting progressing rapidly.
A Potato Council representative said: "Clearance to the end of last week was estimated at 5,349ha compared with 4,298ha at the same time last year.
"New crop movement is increasing, mainly from contract arrangements. Growers are clearing the ground rapidly to meet a good demand from packers, with supplies from a widening supply base. Many crops burnt off for set production are being lifted before reaching maturity in order to satisfy buyers' requirements."
Early yields, however, are slightly down on last year - averaging 32 tonnes/ha compared to 36 tonnes/ha last year.
