Crop
rotation
The
onion is principally self-tolerant. However, as examples show, too
narrow crop rotations may lead to the development of diseases with
origin in the soil, which are difficult to combat, like white rot,
nematodes, pink rot, etc. Thus, a distance of 4 - 5 years in the
crop rotation should be observed.
Grain
as a preceding plant has shown very good results. Potatoes and sugar
beets can also be recommended. Maize and leguminous plants as well
as meadows which have been broken up and which are used for the
first time, are not suitable.
