Abstract: In these conditions is known that with altitude increase the yield and quality of vegetation carpet is decreasing (about a tone of fresh fodder mass per hectare after 1200 m altitude), but in the same time is increasing the species number of vegetation carpet. They can appreciate for wooded grasslands placed at low altitude levels (100-500m) that altitude increase determinates yield, biodiversity, and quality increase of this kind of grassland. The explanation of this phenomenon is tide by the irrationally, free and extensive use of these grassland, altitude increase is associated with the decrease of grazing pressure, these grassland surfaces being exploited incontinuously, and also because the rainfalls quantity available for this ecosystem is increasing with the altitude.
 
Key words: pasture, wooded pasture, yield, pastoral value, pasture biodiversity.

Abstract Fodder beet is a plant species with great production capacity. Roots yield is influenced very much by the main root’s features as weight, length, and maxim diameter. In this work we have presenting the signification of the differences among all differences concerning root length, weight, and maxim diameter studied with t test (Ciulcã, S., 2002).

Abstract. This paper surveys the main effect that the inoculation of white clover seeds with Rhyzobium trifolii strains has against dry matter yield, when we have a mixture made by the following proportions: 40 per cent Trifolium repens and 60 per cent Dactylis glomerata. The bacterial inoculation of white clover from this mixture has increased dry matter yield towards the non-inoculated with clover seeds, with 12.3 % in the first year, 22.3 % in the second year and 14.3 % in the third. In inoculated seeds, under the conditions of nitrogen fertilization, it has been recorded an increasing of white clover proportion in floristic composition of the grassland. In the inoculated mixture the energetic ratio (incomes: outcomes) is 1:47.

RESEARCHES CONCERNING PASTORAL VALUE AND GRAZING CAPACITY OF MEADOW FESCUE GRASSLAND FROM SURDUC’S HILLS
 
Carmen DURÃU, Alexandru MOISUC
 
Banat’s University of Agricultural Sciences and Veterinary Medicine, Timiºoara
 
Abstract This work presents a study on the pastoral value and grazing capacity dynamics of grassland dominated by Festuca pratensis. Vegetation inventory is realized during three years. Even the pastoral value and grazing capacity decrease from a year to another, this grassland is framing in the category of good pastures from economic and forage point of view.
 
Key words: grassland, pastoral value, grazing capacity.

Study of some aspects of Juncus effuses L. invasion in western Romania grasslands
 
Veronica Sãrãþeanu, Alexandru Moisuc
 
Banat’s University of Agricultural Sciencea and Veterinary Medicine from Timiºoara
 
AbstractPlant invasion is difficult to be understood and control, if the processes and factors that intervene in it are known insufficiently. Finding the dominant elements that determine an invasion to succeed at any scale, and the efforts concerning their control, those must to help to the increasing of the efficiency in the control of this phenomenon.

Abstract Observations were realized during 2003-2005 period in 4 permanent grasslands from Banat region. These grasslands are placed in areas with different environmental conditions. Researches concerning Euphorbia cyparissias L. were realised in next localities: Beba Veche, Cenei, Gelu (Timiº County), and Bucoºniþa (Caraº-Severin County).

Abstract. The article presents a study of the relations and interactions between the Glomus intraradices symbionts and the Rhyzobium sp. bacteria drawn from some species of fodder grass plants (Lotus corniculatus L., Trifolium repens L., and Medicago sativa) under the conditions of an argillic brown soil within the Grassland Research Station, Timisoara, Romania. The purpose of our activity was to detect the best variants of combinations of synergism between symbionts regarding the increase of atmospheric azoth use and obtaining in the future possible biopreparates with these symbionts. Starting from on in vitro model, the symbionts have been aseptically isolated from plants and inoculated in the modified Gamborg culture medium (B5), without any source of organic nitrogen. The experimental data have shown the existence of some relations of synergism and antagonism between symbionts. Thus, we remarked a close specificity regarding the synergic correlation between Glomus intraradices fungi and Rhyzobium bacteria taken from the same host plant, the correlation coefficients being positive (Glomus GL-Lc 10+ R. loti, r=0.94; GL-Ms 2+ R. meliloti, r=0.98 and Glomus GL-Tr 4+ R. trifolii, r=0.98). In the situations of combinations between symbionts obtained from different plants, we noticed an antagonic relation, slow development rhythm, the correlation coefficients being negative (Glomus GL-Lc 10+ R.loti, r=-0.94; Glomus GL-Lc 10 + R. trifolii, r=-0.75; Glomus GL-Ms 2 + R.loti, r=-0.92; Glomus Gl-Ms 2 + R. trifolii, r=-0.94; Glomus GL-Tr 4 + R.loti, r=-0.83; Glomus GL-Tr 4 = R. meliloti, r=-0.94).
