GEORGIEV, N. and M. ISHHANIAN, 2002. Caloricity and energetic reserves of the phytomass of two grass associations with the domination of Festuca valesiaca in the region of Liulin mountine. Bulg. J. Agric. Sci., 8: 371–376
There are investigated the caloricity (J/g) and the energetic reserves (MJ/m2) of ass. Festuca valesiaca – Trifolium pratense and ass. Festuca valesiaca, situated in the foot of the north slopes of the Liulin mountine. The average caloricity of the phytomass in the first association is 17 054 J/g, and in the second – 17 189 J/g. The energetic reserves, accumulated in the total overground phytomass of ass. Festuca valesiaca – Trifolium pratense amounts to 6.166 MJ/m2, and in ass. Festuca valesiaca – to 6.466 MJ/m2. Researches of the energetic researves of associations with the domination of Festuca valesiaca have not been made in our country.
