Late processing varieties are reportedly yielding lower than the multi-year average in Belgium, but processed products are said to be of excellent quality. This became clear during trial digs of the Fontane and Challenger varieties recently, according to a report published (in Dutch) by agriculture magazine Nieuwe Oogst.
According to Nieuwe Oogst journalist Han Reindsen, samples were taken on 10 and 11 August to evaluate the yield and quality of the Fontane and Challenger varieties.
