The investigations were carried out in the years 2000- -2004 on permanent grassland in Czarny Potok (Beskidy Mts.- 650 a. s. 1.). Botanical census was conducted by using Klapp’s method on 26 plots (18 random selected plots and 8 controls). The whole floristic material was subjected to numerical classification. As a result, three main types of plots with the dominating species of: Juncus effusus (1), Cirsium arvense (2) and Deschampsia caespitosa (3), were distinguished. Poa trivialis was the dominating species of the control plots. Results of the floristic and habitat analysis confirmed that the main factors determining the formation of meadow and pasture communities are as follows: the method of use, water relations and soil nutrient availability. It was found that idle glades are characterised by degraded sward of the average (the sward patches with the domination of Deschampsia caespitosa) or low use value (the swards patches with the domination of Cirsium arvense and Juncus effusus). The deterioration of the feeding value of the fallow plots is an effect of their high weed infestation, which in turn results, in this case, from habitat changes as a consequence of the cessation of use and earlier errors made in cultivation measures. Both high and low soil moisture, with improper meadow management, accelerated the weed infestation of the sward, what in turn lowers its use value. Cutting and fertilisation positively affect the use value of plant habitats, what was confirmed by the botanical and habitat analysis of the control plots with the domination of Poa trivialis, which is known to be of good use value.

Botanical composition and nutritional value of two-component mixtures containing red clover and different grass species

The field experiments were carried out in 19941996 and were aimed at determining the nutritional value of mixtures containing Trifolium pratense L. + Lolium perenne L., Lolium multiflorum Lam., Lolium multiflorum Lam. var. westerwoldicum and Lolium x boucheanum Kunth. and Trifolium pratense L. + Festuca pratensis Huds.. Based on the botanical analysis, chemical composition and nutritional value, an attempt has been made to determine the variability of the parameters depending on the grass species. The percentages of grasses varied significantly and the variability expressed in the coefficient of variance ranged from 44 to 72.
