LINGORSKI, V., 2005. Yields structure of different grasslands for grazing production. Bulg. J. Agric. Sci., 11: 431-435
The dry matter content and dry matter allocation during the growing season of some foreign (from New Zealand) perennial grasses (cockfoot cv. Kara, cockfoot cv. Wana, phalaris cv. Maru, tall fescue cv. Roa) and grass-legume mixture, cultivated by soil-climatic conditions of Troyan foothill region (Central Northern Bulgaria) during the period 1993-1998, was studied.
Most dry matter content in forage had in the last (5th) cut - from 26.25% to 30.44% and 26.87%, respectively, while at the beginning (1st cut) and in the middle (2nd and 3rd) of growing season was a less.
Most dry mass was provided in 1st and 2nd cuts - from 20.9% to35.1% and 21.3%, and from 18.4% to 23.5% and 23.0%, respectively. During the 3rd and 4th cuts the yields decreased compared to 1st and 2nd cuts, and in the last(5th) cut were almost equally compared to them - from 22.3% to 35.2% and 27.8% from annual production.
