Description
In the years of 1984 to 1992 field experiments have been conducted with different legume-grass mixtures at a location in north-east Germany. Dry matter yield, crude protein and crude fibre content in legume-grass mixtures changed by N-fertilization, grass species, duration of utilization and irrigation. First this was caused by the effect of these factors on yield proportion. The variation of N-fertilization and irrigation influenced red clover grown in a mixture with grass more than lucerne-grass mixture. Irrigation of red clover-grass mixture supported the yield proportion of legume whereas N-fertilization and duration of utilization supported the grass species. Yield proportion, crude protein and crude fibre content were less affected by irrigation and N-fertilization, when lucerne dominated the mixture. The yield proportion of lucerne increased with the duration of utilization and the length of growing season. Festulolium braunii proved to be a more competitive companion than Lolium perenne and Festuca pratensis. In the first year this competition resulted in higher yield proportion of grass and in better dry matter yield of the mixture. The higher yield proportion of grass reduced crude protein of legume-grass mixture and increased crude fibre content.
