E. Alexopoulou, Y. Papatheohari & M. Christou
Switchgrass is a perennial grass that can be cultivated successfully in most of the climatic areas of Europe. In this work the yields of five switchgrass varieties (upland and lowland ones) were compared under three nitrogen fertilization rates (0, 75 and 150 kg N/ha) in a marginal area in central Greece (1998-2010). It was found that yields for all varieties maximized in the second and the third growing year, while from the fourth the yields...
