THE EFFECT OF SOME FACTORS ON WITLOOF DURING STORAGE
In our countries witloof is an important crop: in France 200,000 tons are produced every year, in The Netherlands 22,000 tons; in Belgium the production largely exceeds 100,000 tons. One half of the Belgian production is exported.
Storage and quality problems arise when export markets at great distances are to be reached or when the supply of witloof induces price fluctuations in the producing countries. This can be seen in figure 1.
