Potato production hits lowest level since 2012
The total British potato harvest is down 13% on the five-year average of 5.6 million tonnes, according to the annual Agriculture and Horticulture Development Board (AHDB) estimate.
It makes 2018 the fourth smallest harvest since 1960.
The relatively low production figure (4.9 million tonnes) is a result of an estimated 4.4% drop in planted area and a 12% drop in average yield.
The crop was also heavily impacted by a combination of late planting and the prolonged hot and dry weather that stalled tuber growth in June and July.
The one area of Great Britain that avoided the effects of the summer heatwave was Scotland. Potatoes grown north of the border enjoyed a 3% increase in yield against last year to 49.2t/ha.
But the total production of potatoes in Scotland was still down, due to a decrease of 1,600ha in planted area.
Sector strategy director at AHDB Potatoes Dr. Rob Clayton explained that the average yield decrease is the result of large variations from field to field.
“Growers were battling a shortage of water this year, as you can see on the AHDB weather hub, the combined June and July period was one of the driest on record,” he said.
“Fields that were irrigated will have enjoyed a reasonable crop, while in others yields were very low.”
The estimate also showed only 53% of the land in Great Britain planted with potatoes this year had access to irrigation.
“We won’t run out of potatoes,” continued Dr. Clayton. “We didn’t in 2012, and we won’t in 2018. But what consumers will notice is a wider range of shapes and sizes in the bag they bring home to cook with.
“These shapes and sizes are a normal part of any harvest, they’ll still taste great and will still contribute to the nation’s vitamin C and fibre intake.
“With fewer potatoes around this year supermarkets won’t be able to only choose from the ‘middle’ section of sizes – hence more variety in the bag.”
