Crop tour onions - week 22
Onions recover considerably after precipitation
The seed onions are starting to get an increasingly larger haircut due to the higher temperature and the precipitation of the past period. There is also considerable growth in the lesser plots. Is the delay in the growth of seed onions a thing of the past?
For the Boerenbusiness Crop tour the photos of the onion plots trickle in, one plot is even better developed than the other. Traditionally, onions in the south of the country are further ahead than the rest of the Netherlands, and this season is no different. The lighter soils ensured a better emergence compared to the loam and clay. Early sowing pays off quite well this year.
Late start in Flevoland
On the plot of Aeres Hogeschool in Dronten (Fl) the onions have developed slowly lately. In the meantime, the tide seems to have turned and growth has finally started after the precipitation. "The onions are neatly placed on the incision at the top. There are still some weeds, but we are going to do something about that," says one of the Aeres students.
In the Groningen area of Eenrum, where the emergence was hindered by the crust, the onions are growing, but the condition is moderate. The hoeing has helped a bit, but the ground has again become reasonably closed due to the precipitation.
Forerunners in the South
The situation is different with Geert Jilissen from Oeffelt (NB). He has previously covered an onion plot and sowed silage maize, but his Crop Tour plot is in excellent condition and the onions are already working on the fourth pipe. This is at its lightest and most beautiful in terms of soil and was sown on March 14th. In addition, he once watered before the emergence. The seed onions are well developed, so Jillissen plans to start disease control next week.
A little further south in Ysselsteyn, Limburg, is the plot of onion grower Martijn Derikx. He sees the onions growing like cabbages. The drip irrigation has not been happy with the rainfall of recent times. However, the precipitation was very distributed in his region, says Derikx.

Spotted first trips in Zeeland
Klaasjan Boer from Kortgene (Z) has already found thrips in all three onion plots. He plans to spray against this with Batavia next weekend. The onions are working on the third or fourth pipe, but they have a moderate setting. The drought and partial scab are the culprits, which have led to plant failure. As a result, Boer thinks he will be left with between 600.000 and 650.000 plants per hectare. As with most onion plots, growth is now good after the precipitation. Last weekend the onions were richly rewarded with 25 millimeters, and in the first half of this week another 6 millimeters of precipitation was added.
