Crop tour onions - week 20

Growers on average are very satisfied with the emergence of onions

17 May 2023 - Robert Reijerse

The rows of seed onions are now clearly visible on the first plots. Many growers participating in the Boerenbusiness Crop tours are satisfied with the emergence, but there are regional differences in growth stages between the plots of yellow onions.

More than enough moisture and pleasant temperatures resulted in good emergence on most plots. Especially if we look at the past few years, the growers are positive about the number of plants they count in the field. Scab formation occurs on onions sown at the end of April or the beginning of May.

Crust formation by precipitation
The crust is broken on Jan Berend Biesheuvel's plot. The onions were sown on May 2 and after that time the onions had to endure a lot of rainfall. This resulted in crust formation, after which Biesheuvel made the choice to break the crust with a crust breaker.

Growers generally satisfied with plant number
Arjan Bos, cultivation specialist at Hazera Seeds, sees many plots with crust formation. "Especially on the plots that were sown at the end of April and the beginning of May. In several places, onion plants have been lost due to the downpours. It is not perfect everywhere, but in general the emergence is not bad. Furthermore, this year I see that primed onion seed for a even emergence ensures more plants per meter."

On the plot in Eenrum (Gr), Dirk Binnema is satisfied with the turnout. "The onions have always had a little moisture, so that enough plants have come up." The onions are now flagging and were sown April 19, almost a month ago.

David de Wit from Lepelstraat (NB) is also satisfied. There are approximately 900.000 plants per hectare on the plot. "There are more plants on the plot and the emergence is more even than in recent years." The onions are flagging and the first pipe is on its way. This ensures a nice even image.

The onions are now in the first pipe on the plot in Wezup (Dr). "The number of plants was good upon emergence, but due to the driving rain in recent weeks, some plants fell away. But I'm still satisfied with the emergence. The onions are spotlessly clean of weeds. We'll wait for the warm weather next weekend and see what we have to do in weed control."

Patience to plant
Wim de Witte from Steenbergen (NB) went to see what the soil was like for planting potatoes, but found the soil not yet suitable for planting. From above it seems dry because of the gray color, but below it is very wet. Due to the temperature and the wind, the ground dries up quickly.
