METHOD OF SELECTION OF GRASS MIXTURE COMPONENTS FOR HIGH YIELD HAYMAKING GRASS STANDS

Abstract

Using growth uniformity index evaluation has been carried out and the varieties of perennial grasses with high adaptive capacity for haymaking grass mixtures have been identified. It’s established that grass stands on the basis of Festulolium with alfalfa or Trifolium repens (from 75-78 dt/ha to 93-109 dt/ha) have the highest yield with three and four cut use. The grass stands on the basis of brome and alfalfa are the most suitable for three cut use. Application of nitrogen fertilizers in a dose of 30 kg/ha and 60 kg/ha to every cut of legume grasses with the use of alfalfa provides the largest gross output of raw protein (18,5-23,5 dt/ha).
