VALUE OF CRUCIFEROUS GREEN FODDER AND GREEN MANURE CROPS

The results of the varieties of the Belgian list of varieties of cruciferous green fodder (rape and turnip) and green manure crops (mustard and oilradish) are presented in this article. Only the data of the official trials are calculated. Varieties of fodder rape and turnip with high qualitative characteristics, such as a good resistance to frost, a low content of tare and a good digestibility, are being preferred. Compared to oilradish, mustard is preferred for later sowing. For both species, varieties with a late flowering date, a fast ground cover, a high resistance to frost and a relatively short plant length are preferable. The choice between varieties resistant to beet cyst nematode or other depends on the rotation of crops and on the sowing date. In the category of resistant varieties, preference is given to those with a very low multiplication rate for beet cyst nematode.
