Unterallgäu maize trial compares 34 varieties

A field trial in Unterallgäu, Germany, is comparing 34 different maize varieties from twelve different seed houses. The study aims to determine which varieties are best suited for specific uses, such as silage for dairy cattle, biogas production, or cultivation on dry soils.

Organized by Raiffeisen Ware Schwaben-Allgäu, the trial near Kirchheim utilizes a site that previously grew rapeseed. The use of rapeseed as a preceding crop is noted for its ability to improve soil structure and provide nitrogen through nodule bacteria, while the remaining straw helps return potassium to the soil.
