LINGORSKI, V., 2002. Study of some temperate grasses and grass-legume mixture for grazing production. Bulg. J. Agric. Sci., 8: 533–538
The dry matter content and dry matter allocation during the growing season of some foreign (from New Zealand) temperate grasses (cocksfoot cv. Kara, cocksfoot cv. Wana, phalaris cv. Maru, tall fescue cv. Roa) and pasture grass-legume mixture, cultivated by soil-climatic conditions of Troyan foothill region (Central Northern Bulgaria) during the period 1993–1998, was studied.
The biggest dry matter content of the forage had in the end of growing season (in 4th and 5th harvestings) – from 24.59 % to 26.05 % and from 26.25 % to 30.44 %, respectively.
Mean for the sixth year period the greatest dry mass yield was obtained from phalaris cv. Maru and from tall fescue cv. Roa – with 12.5 % and 8.8 % more than cocksfoot with total origin as a Standard.
An even distribution of the accumulated dry mass in the forage was allocated comparatively equally only in first three cuts as follows: in 1st – from 21.9 % to 25.0 % of annual production; in 2nd – from 21.2 % to 24.9 % and in 3rd – from 19.0 % to 21.7 %, respectively and after that decreased in 4th and 5th harvestings.
The sown grass cultivars as monocultures and grass-legume mixture had comparatively a big swards part to the last year of investigation and reached within 70.1 % – 80.0 %.
