Einfluss verschiedener Anbaustrategien auf Ertrag und Pflanzengesundheit von Zwiebeln (Allium cepa L.)

Summary

In field experiments in five Bavarian farms three cultivation systems of onion produc-tion were compared: direct sowing, planting of set onions and planting of seedlings with 7 seeds per each tray. In three of five farms the onions yield up to more than 500 dt ha-1and in average the planted seedling yielded higher than the sown ones. In the other farms, where the set onions where included in the trials, the yields were lower depending on the high and early infection with downy mildew. The plant density (90-70 plant m-2) had more effect on the onion size distribution than on the total yield.
