Abstract: The introduction and generalization in production of the latest technologies for fodder cultivation must also rely on the calculation of the economic efficiency. The purpose of these calculations is to give an opportunity to each producer for choosing the optimum technological variants, with great productions on the surface unit, of high quality and low costs. In general, in the classical intensive technologies of fodder cultivation, there isn’t always a direct correlation between the level of the achieved productions and the size of the economical indicators, because the economic efficiency is very much influenced by the value of the expenditures made. In a zootechnical farm the fodder is to be found through the animals and respectively through the products obtained from the animals and subsequently the economical efficiency is not directly related to the profit rate. Moreover some fodder is not bought/ sold. Some fodder is only cultivated in specialized zootechnical farms for feeding herbivores, which daily consume significant quantities of biomass (1UVM- daily consumes 50-60 kg of green mass). We have calculated the economic efficiency of the Alfalfa and English Ryegrass because of the fact that the hay of leguminous plants and gramineae are commercialized on a large scale in the Banat area. The average selling price of Alfalfa hay is 0,078 €/kg, and that of the English Ryegrass is 0.065 €/kg. The application of the bio-stimulators for growth in the case of Alfalfa and English Ryegrass cultivation led to an increase of the hay production per hectare, which also led to an increase of the revenue obtained per surface unit.

Abstract: In order to increase the production of the mangel-wurzel-beet, the improvement of the quality of the crops is expected, which will be achieved using genetic engineering techniques and modern technologies, such as the usage of vegetal bio-stimulators with the purpose of influencing the growth and the development of the plants. Nowadays the bio-stimulators are very often used in biological agriculture not only for lawns, but also for fodder cultivation, successfully replacing some polluting products. The agro fond and the crop-rotation have had a direct influence on the level of production of the studied mangel-wurzel genotypes in Timisoara (2007-2008). To the two factors mentioned above, the positive influence of the products with a bio-stimulating role was added. The beet capitalizes on manure. At all doses of manure applied, increases of production are obtained in comparison with the untreated sample. The greatest increases of production are obtained at the mangel-wurzel breed Kyros, at a dose of 80 t manure/ha. (132,9 kg/ha). Analyzing these measurements from the point of view of the increase in production for 1 kg of used manure, one can notice that at the doses of 40 and 60 t/ha, the increases in production are higher than at the maximum dose for the mangel-wurzel.

Abstract: In this work is presented the evolution of the vegetation carpet from some sandy land grassland under the influence of exploitation intensity. The purpose of these researches is to analyse the dynamics of the vegetation in the condition of the improper management, because this is the condition of most of the Romanian grasslands. Also, this research is concerned by the botanical composition of the vegetation carpet, the structure of the vegetation from the point of view of the main plant types (grasses, leguminous, Cyperaceae and Juncaceae, and species from other botanical families) species number, and aspects concerning the biodiversity. The data were collected from 4 grassland surfaces (Lenfin – hayfield, Fürkó, Dihenes and Urkuta – pastures) from the land surface of Valea lui Mihai locality during 2007-2008. The research methods used in this work are the vegetation analysis with square meter method (Daget et Poissonet, 1971) this type of data collecting offering data that can be used in the detailed calculus of biodiversity (Shannon-Weaver) and dominance (Simpson) indexes. The results obtained shows that the greatest biodiversity is found in the case of Lenfin hayfield, and in the case of the pastures the obtained indexes have similar values they showing a medium biodiversity index. For the improvement of the botanical composition of the grasslands from the area of Valea lui Mihai are needed some immediate measures as are: mowing the non-consumed plants to reduce the weed proliferation on the grazed land surfaces (Fürkó, Dihenes and Urkuta); fertilization of the hayfield and of the pastures; the use of the grassland only for grazing (not for deposition of wastes); the elimination of water excess in the case of Urkuta pasture there being  present in a great amount hydrophytes plants species.

Abstract: Grasslands are an important resource of Valea lui Mihai (Bihor County) they representing more then 22 % form the total agricultural land of the locality.  Most of the grasslands are used under their natural capacity, because most of the times the lack of the maintenance works and the overexploitation or under exploitation are determining the reduction of the biomass yield. Usually the grassland surfaces that are closer to the settlements are overexploited and those that are farther are underexploited. The topic of this work is the productivity of some sandy land grassland from Valea lui Mihai (Bihor County). The purpose of this research is to reach pieces of information about the productivity of the analysed grasslands. Another aspect taken in account in this work is the pastoral value of the grasslands and the carrying capacity of the surfaces that are used for grazing. The data were collected from 4 grassland surfaces (Lenfin – hayfield, Fürkó, Dihenes and Urkuta – pastures) during 2007-2008. The research methods used in this work are measurement of the yield with the direct method respectively the method of the repeated mowing, and the determining of the carrying capacity per hectare of the grassland surfaces used for grazing. The harvests were grouped in three cycles and from every of the grassland were collected samples of fresh fodder from six plots. The results obtained in this research show that the grassland vegetation from the studied area has a great stability from the point of view of yield, and carrying capacity. The differences consist in the yield distribution on harvests, these being influenced by the repartition of the rainfall during the vegetation period. The number of the animals that are using the grassland is greater then the carrying capacity of the pastures used, and the forage deficit must to be provided from forage crops cultivated in arable land.

Abstract: In this paper are presented our results regarding the influence of mineral and organic fertilization on the Na, K, Ca and Mg contents in forages harvested from a permanent meadow situated in a hill region of Banat County (Grãdinari; Caraº-Severin). Mineral fertilizers used were NPK complex, ammonium nitrate, super phosphate and potassium salt. Fermented manure sheep was used like organic fertilizer. The mineral fertilization was made yearly, whereas the sheep manure was applied at each two years. The Na, K, Ca and Mg contents have been analyzed using flame atomic absorption spectrometry (FAAS). The correlations between analyzed minerals contents in forages and mineral or organic fertilizers are discussed. Both fertilizers influenced the Na, K, Ca and Mg contents of the forages, but in different manner.

Abstract: Lolium multiflorum presents a number of qualities that can successfully integrate into the structure of fodder crops in a modern animal husbandry. Starting from these considerations, in this paper we aimed at addressing a number of issues that determine the production of dry matter and intake of scythe I and II to achieve it. The experience has been located in Timisoara, for three consecutive years (2006-2008), on an agrofund on the N50 P50 K50 (at the starting of the culture) and N50 after first scythe. As biological material we used a Wesley variety of Lolium multiflorum var. Westervoldicum. The year’s influence was decisive on the culture of Lolium multiflorum, so the scythe production was very high (4,5-5,1 t / ha) and of good quality. Because of drought in June-July with scythe II very low yields have been obtained (0,6-1,05 t / he SU). As such, on the specific conditions of culture in Timisoara we recommend only scythe I for Lollium multiflorum, after following a successive crop.

Abstract: In Grãdinari (Caraº Severin County) grasslands are representing about 33 % from the total agricultural land of the locality being important natural resource from this point of view, they being the topic of this research. Some of the grassland surfaces are coming from the abandoned agricultural land. One of the most important maintenance works needed in grasslands is represented by fertilisation. Every type of grasslands has different fertilisation needs, so the importance of this research is to set the optimal fertilisation rate with for different types of fertilising (chemical, organic and mixed). The purpose of this work is to find the optimal fertiliser rate for the grassland from Grãdinari. The experimental plots were set in Grãdinari (Caraº-Severin County), in 2004. The experimental plots comprise three fertilisation experiences: organic, chemical and mixed. Every fertilisation experience is organized in ten variants and five replicates. These were set after the blocks method. The surface of one plot is 20 m2 (4m x 5m). The data were collected during 2004-2007 period. Thus, there was measured the total yield of fresh fodder and hay for every fertilisation variant from the abandoned arable land grassland and from the permanent grassland. After the analysis of the production results obtained can be noticed that the fertilisation of an abandoned agricultural land that is in succession to the grassland vegetation, the effect of the fertilisers is most powerful from the point of view of the yield starting with the second year from the fertiliser application. In comparison with the abandoned agricultural land in succession, the permanent grassland is visibly influenced by fertilisation starting with the first year from the fertiliser application.

Abstract: The effects produces by flooding on the ecosystems are the followings: injuries on the biodiversity; reducing and degrading the natural habitat; the lack of drinking water for wild animals; the appearance of the epidemics in plants and animals; the appearance of the phenomena of  migration and forced concentration of some species; the increase of the extinction risk of some endangered species; the modifying of the soil salinity; the increase of the soil erosion risk; the modifying of the water quality; landscape modifying. The present work represents a study of the flora and vegetation from the area set under the influence of the flooding in the Timiº – Bega inter-river. Thus were realized researches on the changes appeared in the vegetation cover of some grassland flooded for different intervals of time. The study was realized on three grasslands from the perimeter of Grãniceri locality and three from Foieni locality, Timiº County. All surfaces were flooded in April 2005. The researches were developed during a period of three years, respectively 2005-2007. This work is looking to define aspects concerning the influence of the flooding duration on the features of the vegetation cover from the studied areas, respectively the pastoral value. After the analysis of the data obtained we can conclude the followings: the pastoral value of the analyzed grasslands is evolving ascendant from a year to another showing that these vegetation communities have a great capacity of recovery after disturbing factors, in this case the flooding; the increase of the pastoral value of the grasslands in the years following the flooding can be assumed on the contribution of the nutritive elements brought by alluviums on these surfaces; the pastoral value with ascendant sense is determined by the increase of the participation in the vegetation carpet of the species with forager value better from a year to another.

Abstract: There are cases when long-term human activities and their interaction with nature have created agro ecosystems with high conservative value of flora and fauna. Such agro ecosystems are among others, old grasslands and meadows, specific forms of traditionally managed forests, or even mosaics of grasslands, cultivated fields and forests. These land mosaics, formed usually by traditional land use systems of low intensity, result of handwork with simple apparatus and animals, are known as traditional (or historical) cultural landscapes or shortly cultural landscapes (Ewald, 1994; Meeus, 1995; Phillips, 2001; Konold, 1996; Müller, 2005; Konold et al. 2001; Farina, 2007; Forman and Gordon, 1986). In our country, a precious landscape from cultural and pastoral point of views is constituted by the one in Apuseni Mountains, where, in time, traditional human activities marked the mountain landscape making it unique in Romania and in the world.  With a high degree of novelty and originality, the study of mountain landscape elements brings forward some specific peculiarities to Apuseni, as well as their shaping and maintenance, but also the possibility of loosing them once new exploitation and building technologies are introduced or due to abandonment. The study was performed with the help of satellite images. The management practices of land, in time, have generated a mosaic landscape dominated by landscape elements which individualizes it. Among these, the following distinguish themselves: enclosures, rocks piles, isolated trees, lopped spruces, Fagus with contorted trunk, houses with roof made of spruce  and fir branches, hay piles, fallowed terraces, enclosed arable land patches, forest grazing, meadows with plum trees, permanent and seasonal houses traditionally built, houses built at high altitude etc.

Abstract: Perennial grasses are important mainly for forage and for turf. The purpose of this work is to highlight grass species that are growing spontaneously in our geographic area, which have features that make these species suitable for their use in turf mixtures. There are valuable populations that are best adapted to the ecological conditions of our country, they being resistant to a series of factors that are recommending them for the use in turf mixture. The features that make the grasses suitable for this purpose are: resistance to treading, fast recovery after mowing, resistance to drought, resistance to shading, resistance to diseases and pests, resistance to repeated mowing, turf density, the finesse of the leaves, facile setting, etc. The grass species considered in this research is Festuca valesiaca. In Romania weren’t created yet autochthon turf grass varieties, all the seeds coming from import or being foreign varieties multiplied in our country. This type of research is very important because the turf has started to capture the interest of the municipalities and private owners from our country, they being interested to have turf covers with high esthetic and functional qualities. Also is important for them to have varieties adapted to the ecological conditions of the area where the turf will be set. This study is only a first step in the selection of germplasm resources for the creation of new turf grass varieties because in our country are created some small grass varieties, but they are suitable for forage.

Abstract: The purpose of this work is to show the evolution of an ornamental turf seeded by the municipality in the Opera’s Plaza in Timiºoara (Timiº County). The turf was seeded at the end of March 2006 after the former vegetation carpet was totally removed with the first 10 cm from the topsoil. After the soil preparation and the primary fertilization phase there was seeded a turf seed mixture of Lolium perenne, Poa pratensis and Festuca rubra. The analyzed aspects of that turf were the NTEP quality ratings of turf. These are evaluated on a 0-9 scale where 9 is best and 1 poorest. An average rating of 6 or above is characterizing an acceptable turf. The rating value of 9 is characterizing generally a perfect or ideal turf grass, but sometimes this rating can characterize a best managed turf that is in perfect accordance with the ecological conditions of the site where is placed. The quality ratings are important for taking into account in a measurable way the aesthetic and functional aspects of the turf. These determinations are based on the evaluation of color, density, uniformity, texture, and resistance to diseases and pests and environmental stress. Some of the features can be important for one turf type and less important for other. For example, color is an important feature for the ornamental turf while traffic tolerance is important for a sport turf. Even the turf was totally renovated there appear problems concerning the density in some points and the weeds starting from the first year of vegetation. There are present both dicotyledonous and monocotyledonous weeds, and their number is growing from a year to another. The proliferation of weeds in turf is favored by the defective management of the turf, especially by the irregular mowing and fertilization. This type of study is important because there are only few researches on turf in this part of the country, most of them being realized in experimental conditions, that may differ powerfully especially from the point of view of frequency maintenance works.
