Effect of Seeding density on Plant Interactions in Cereal Systems with Associated Cover Crop

The success of the establishment of living mulch systems in cereals depends, among other factors, on the seeding density of the main crop and the associated crop. A series of experiments with 6 seeding densities of subterranean clover and 2 seeding densities of wheat was performed in southern Germany in order to assess the role of this factor using model systems with wheat and subterranean clover. Increased seeding densities of subterranean clover increased subterranean clover biomass, reduced wheat tiller density, but improved N supply to wheat in the stem elongation stage
