The total area of potato planted in Britain is the third lowest on record at 117.47k/ha, according to a revised Agriculture and Horticulture Development Board (AHDB) estimate.

The driving force behind the reduction has been a scaling-back of potatoes planted for the processing market, which after four consecutive years of growth has now dropped below the planted area of 2016.

An estimated 34.8k/ha was planted with the intention of reaching processing markets, representing a drop of 7.1% (2.7k/ha) year-on-year, or 3.6% versus the five-year average.

Potato processors have been hit badly by the coronavirus outbreak, as lockdown saw wholesale closures of restaurants, fast food outlets, schools and other venues.

The largest area was made up of potatoes planted to be pre-packed for supermarkets, at an estimated 44.32k/ha. This is a rise of 698ha, +1.6%, compared to 2019.

This comes amid strong retail performance for fresh potatoes in supermarkets at the time of planting. The volume of potatoes sold at supermarkets in the 12 months to August 9 is up 8.4% against the same period last year according to Kantar.

Alice Bailey, senior analyst for potatoes at AHDB, said:

This estimate is based on receiving 90% of growers planting returns. Our earlier estimates showed a smaller decline in planted area and it was thought that the timing of the pandemic, arriving as planting was kicking-off in earnest in March, had not allowed growers enough time to adjust their plans.

“Since the estimate based on 80% of growers, some larger growers have submitted their planted areas showing they have dropped their area more significantly than many of the earlier submissions.

“This has caused a larger drop than usual and highlights that, with 10% of submissions still outstanding, we could see some further changes to these estimates.”
