Assessment of the parameters of adaptability of individual populations of the cocksfoot in the Arctic region
Abstract Perennial grasses play an important role in increasing land productivity and increasing the production of high-protein fodder. They are grown in field and fodder crop rotations, in cultivated hayfields for green fodder, hay, haylage, grass cutting and grass meal. In the fodder balance, they...
