Non-leguminous forbs are important constituent of extensive grasslands. The information on their nutritive value is scarce. The present investigation gives a survey on the changes in protein concentration and energy value during the primary growth. Composition and energy value of common yarrow, ribwort plantain, dandelion, broad-leaved dock and hedge bedstraw sampled from two locations were investigated at four sampling dates. At comparable sampling dates the highest value of crude protein concentration (CP) was found in broad-leaved dock (166 to 271 g kg-1 DM) whereas the lowest values were found for common yarrow (70 to 164 g kg-1 DM). The highest metabolizable energy (ME) concentration was found in dandelion (9.66 to 11.30 MJ kg-1 DM) and the lowest in common yarrow (5.14 to 9.89 MJ kg-1 DM). Based on linear regression model the highest rate of CP and ME decline was obtained in broad-leaved dock (-3.76 g CP kg-1 DM per day, R2=0.92; -0.054 MJ ME kg-1 DM per day, R2=0.67). The lowest rate of CP and ME concentration decline was found in dandelion (-1.10 g CP kg-1 DM per day, R2=0.41) and in ribwort plantain (-0.026 MJ ME kg-1 DM per day, R2=0.41). It was concluded that species of non-leguminous forbs differ among each other both in concentrations of CP and ME, as well as in rate of their decline during the growth.

Within the experimental fields of the Infrastructure Center Jablje two ecotypes of cocksfoot (Dactylis glomerata L.) and tall fescue (Festuca arundinacea Schreb) were seeded in individual plots. The objective of the study was to evaluate the nutritional value of both species at relatively late first cut. Samples were collected at four different dates of first cutting: 22.5., 2.6., 12.6., and 24.6. The chemical composition and net energy value for lactation (NEL) were determined using near infrared reflectance spectroscopy (NIRS). At comparable harvesting dates the crude protein content (CP) and net energy for lactation (NEL) were higher in tall fescue, while the crude fibre content was higher in cocksfoot. During the observed period, the CP content decreased more rapidly in tall fescue (-1.09 vs. -0.74 g CP per kg of dry matter per day), while the NEL content decreased more rapidly in cocksfoot (-0.029 vs. -0.022 MJ NEL per kg of dry matter per day). Significant differences in the decline of nutritional value between the two plant species were observed. It was also found out that at comparable date of the late first cut, tall fescue has a higher nutritional value than cocksfoot.

The article provides an overview of vegetation and flora of the nothwestern part of the Banjšice mountains (the western Banjšice plateau), using the standard Central-European methods. The main types of vegetation are forest and grassland. The most of forest stands are classified into the associations Ornithogalo pyrenaici-Fagetum, Lamio orvalae-Fagetum, Seslerio autumnalis-Fagetum, Seslerio autumnalis-Ostryetum,Veratro nigri-Fraxinetum and Ornithogalo pyrenaici-Fraxinetum. Dry meadows belong to sub-Mediterranean communities from the order Scorzonero villosae-Chrysopogonetalia grylli, especially to the association Danthonio-Scorzoneretum villosae. Pastures and meadows on relativelly fertile mineral soils are classified into the associations Ranunculo bulbosi-Arrhenatheretum, Anthoxantho-Brometum erecti and Rhinantho freynii-Trisetetum flavescentis, and on acid soils into the association Polygalo vulgaris-Nardetum. Some special features of flora of this transitional region between the Julian and Dinaric Alps and (sub)Mediterranean are (south)eastern-Alpine endemics Saxifraga tenella, Aconitum angustifolium, Tephroseris pseudocrispa and Leontodon hispidus subsp. brumatii, some Mediterranean species like Adiantum capillus-veneris, Linum bienne and Orlaya grandiflora, mostly Illyrian species Scopolia carniolica, and many protected taxa from the family Orchidaceae.

Soil nutrient supply, forage yield and quality as well as botanical species composition were determined on fertilised and extensive meadows of 15 farms in the Karst region and 16 farms in the Soča Valley region. In the Karst region soil P2O5 content was significantly higher (P ( 0.05) on fertilised meadows than on extensive meadows (14.8 vs. 4.85 mg/ 100 g soil). In meadows of Soča Valley region the difference was not statistically significant (P ) 0.05; 7.66 vs. 4.86 mg/ 100 g soil). In both regions the soil K2O content was higher on fertilised meadows than on extensive meadows, however, the differences were not statistically significant (P ) 0.05). Dry matter (DM) yield (3120 and 8159 kg/ hectare), crude protein (CP) content (104 and 144 g/kg DM), NEL content (5.10 and 5.27 MJ/kg DM), P content (2.45 and 2.82 g/kg DM), K content (17.0 and 23.2 g/kg DM), CP yield (330 and 1178 kg/ hectare) and NEL yield (16.0 and 43.0 GJ/ hectare) were significantly (P ( 0.05) higher on fertilised meadows than on extensive ones (1844 and 4684 kg DM/ hectare; 94 and 116 g CP/ kg DM; 4.64 and 4.85 MJ NEL/kg DM; 1.43 and 1.80 g P/kg DM, 10.3 and 16.5 g K/kg DM, 174 and 567 kg CP/ hectare; 8.74 in 23.0 GJ/ hectare). Compared to the results of the Karst region the DM, CP and NEL yields in Soča Valley region were more than twice as large. In Soča Valley region, statistically significant lower numbers of plant species were determined on fertilised meadows than on the extensive ones (28.5 vs. 46.3, P ( 0.05). In the Karst region the difference was not significant (36.6 vs. 40.1; p ) 0.05). In both regions lower number of red list species were identified on fertilised meadows (0.47 and 0.06) compared to extensive meadows (1.27 in 1.0) (P ( 0.05).
