Crop tour potato - week 33

It's over and over with the regrowth in potatoes

17 August 2022 - Robin de Winter

The potatoes are wearing out at a rapid pace and although a few arable farmers are still irrigating, most growers indicate that it is over. The growers participating in the Boerenbusiness Crop tour hope for a few extra pounds, but don't expect much. 

The impact of the ongoing drought is becoming more and more visible now that the crop is at its end. The plots planted later can in some cases still be used for a while. As for Innovator, it's the end of the game for most lots. Some hope to see another 3 to 4 tons grow, but are not really counting on that anymore.

Over and out
Daan Goense from Driewegen (Z) does not ignore it: "The moisture from the irrigation has run out and they wear out very quickly." He hopes to see another 2 or 3 tons grow and then has to make do with 45 tons net. At the end of last month, Goense irrigated his Gewastour plot for the first time with a kilometer of hoses to his water source. With 35 millimeters out of the reel, the Innovator had to make a final sprint and that seems to have been done now. The moisture is gone and the color disappears.

Kees Trouw from Hellevoetsluis (ZH) has his potatoes still green. He rained last Monday, but Trouw does not know whether the potatoes will grow much after the heat wave. Estimating how much the crop will continue to grow after the trial harvesting Trouw does not dare to do. With a net weight of approximately 50 tons, it did well in the test harvest, but the underwater weight (OWG) was on the low side. However, because the plot is still green, Trouw is not concerned about the OWG.

He was harvesting another variety on Tuesday and arrived at 52 tons according to the yield meter on the potato harvester. It was not easy, despite the 20 millimeters that Trouw had previously applied to the plot. It is so bone dry in the potato ridge that hard clods come up with the potatoes. Trouw is satisfied with the 52 tons, but is disappointed with the variation in size.

Jacco van Liere from Dronten (FL) also sees that most of the growth comes from his Gewastour plot. The stems are still green, but that's about it. But green still means growth. Van Liere was by far the first of the Gewastour to plant his Innovator and stands at 54,4 tons at the trial harvesting. That figure is likely to increase only slightly.
