Traditionally, the trial harvesting season starts in week 30 before the main harvest. Also this year Aviko Potato will publish its trial harvesting data via its website. Will the extremely dry spring leave its mark?
Aviko's trial harvest involves more than 50 plots spread across the Netherlands, Belgium and France. The trial harvesting has been done for more than 10 years and therefore gives a good idea of the growth trend that is currently taking place in North-West Europe. However, the publication on the website only concerns the Dutch plots and is a mixture of different chip varieties (Innovator, Fontane, Victoria, Markies, Agria and Challenger).
Above last 5 years
In terms of kilograms in week 30, the yield appears to be slightly above 30 tons per hectare. This is a similar start to the 2016 yield, clearly at the top of the past 5 years. What is particularly striking is the record coarseness and that the average coarseness of the sampled plots is already above 70%, the highest number in the past 5 years. The underwater weight (OWG) is again on the line of 2016, but significantly lower than the past 2 seasons, which were very dry years (2018/2019).
Potentially good harvest
The tentative conclusion that can be drawn from these first figures is that a good harvest is potentially growing. In general, the crops are also very vital. This is partly caused by the growing weather. Mild temperatures, dark weather and occasional showers do their work on the potato plots. The size seems to indicate a lower tuber number than average. Something that is often reported, especially at Innovator and Agria plots. Fontane and Challenger appear to be in sufficient numbers and the crops of these varieties are considered exceptionally vital.
