The study is part of the research project "Development and testing of an agroforestry system combining organic agriculture and short rotation coppice". Cooperation partners are the Bavarian State Institute for Agriculture (LfL) and the Bavarian State Institute of Forestry (LWF). The two experimental sites are located in the northern
Munich gravel plain near Freising and in the southern part of the Franconian Jurassic near Kaisheim. Aim of the study was to compare the yield of agricultural crops in an
alley cropping system for woody biomass production with a standard cultivation without trees on the field. A positive effect of periodically harvested tree stripes on the
yield of the agricultural crops is expected. First results show that there were no significant differences in the overall marketable yield of winter wheat in the
agroforestry system compared to the reference site without trees. The spatial distribution of the yield, however, differed significantly. In close proximity to the tree
stripes a significant reduction of the marketable yield could be measured. These lower yields were equalized by higher yields in bigger distances of the tree stripes
