Description
An experiment was conducted in the Central Rhodope Mountains, 1,880 m a.s.l., between 1969 and 1974, using red fescue (Festuca rubra L.), timothy (Phleum pratense L.), cock's foot (Dactylis glomerata L.), and bird's-foot trefoil (Lotus corniculatus L.), with 100 kg nitrogen and 80 kg phosphorus being applied to one hectare per annum. The tests were undertaken by cutting at grazing maturity. The following conclusions were mainly drawn from six-year observations and results obtained therefrom:
(1) Red fescue (Festuca rubra L.) was highly adaptable. It formed high-density plant stands and ensured the highest yields of green matter, dry matter, and crude protein.
(2) Red fescue soon expanded to the order of 80 or even 90 per cent of the entire plant stand and became the predominant species, no matter how much of it had been included in the mixture originally sown. The structure and composition of a given plant stand d obviously depend on the extent to which soil and climate as well as the method of use meet the demands of the species grown.
