The Dactylis glomerata L. species is found in a  spontaneous state in the meadows of Romania. It is an essential component in the composition of simple mixtures with alfalfa and complex mixtures along with other grasses and perennial legumes. The manifestation of agrobiological characteristics in Dactylis glomerate L. is characterised by complexity and variability, influenced by technology, soil, and climatic conditions that vary inherently in space and time. The research was focused on the knowledge of the agro-biological characteristics and production capacity of the species Dactylis glomerata L. in correlation with local conditions. The research was carried out at Agricultural Research-Development Station of Lovrin and as a biological material the cock's-foot genotype LVDG1 was used, the culture has been established in the Autumn of 2020. Biometric measurements were made on the main agro-biological characters until the first scythe was harvested as a green mass feed. Research shows that all parameters analyzed have the same tred, in both experimental years, with small variations, the differences being attributed to the lack of uniformity of precipitation, the temperature not being a restrictive factor. In the case of the experimental site, the characteristics and type of variation of the decadal quantities of atmospheric precipitation, expressed by the modified Angot index (km), show that in the range of 1.01 to 31.05. 2021, the decades with a pluviometric surplus prevail, with large differences compared to the same period of 2022, which is also found in the externalization of the characters in cock's-foot. The rainfall in the year 2021 contributed to a better expression of vegetative parameters, including the production of green mass at the first scythe. Hence, in 2021 was the highest production of green mass at the first scythe of 25 t.ha -1.

Grasslands are spread all over the globe, their distribution being possible by various modern methods. The spatial representation of the grasslands, in correlation with other categories of land use, provides us with an overview of the activities of the geographical area and also represents a first stage in the field research. In this context, the purpose of the research is to analyze the territorial distribution of grasslands through geographic information systems (GIS), based on land use maps and to identify natural and anthropic factors with direct and/or indirect impact in their spatial modeling. The study area is characterized by variable conditions of landform, being partially located in the following physical-geographical units, Vinga plain, Gătaiei plain, Timiș plain, Lipova Hills, The Sacoș-Zăgujeni Hills and Anina Mountains. As representative of the analyzed area, we chose five ATUs, framed in a working transect. In the sub-areas of the analyzed work transect there are variations in the way of organizing the land, respectively in the territorial distribution of the grasslands. Thus, the largest areas of grassland are present in ATU Recaş (6253,83 ha) which has a hilly appearance (with altitudes between 90 – 287 m). Large areas of grasslands are also found in ATU Fârliug (3.163,23 ha) and ATU Pișchia (2255,25 ha) located in different landform conditions. The smallest areas of grasslands are found in ATU Vermeș, respectively 861,63 ha. From the point of view of the territorial distribution, the areas of grasslands shall be grafted on all forms of landform and under all environmental conditions in the territory under consideration. The share of grassland depends on natural factors (soil, climate, landform) but also on the other production activities, specific to each area, which is also found in the distribution of the other land use categories, for each ATU.
