Abstract: In order to increase economic efficiency in agriculture is necessary for each farm profitable endeavor for all products and organizational structures, but also to increase at a more intensively rhythm to achieve the competitiveness required by the competitive market. Agricultural unit should consider choosing an optimal structure of crops to ensure high benefits but also allow for appropriate crop rotation. It also required the purchase of equipment for executing works best period in terms of agro and fall in production technology performance. It was made an analysis of the profit obtained by the unit after production use and a determination of the necessary equipment for surface under study.
In determining the need for tractors and agricultural machinery in a specific farm taken into account it is a must to provide the whole range of agricultural works in terms of quality, demanded by technologies. Account has been taken of the whole complex of interrelated elements that are specific to the studied farm. In their totality, they can be grouped into two major categories: factors that influence the structure of the tractors and agricultural machinery, namely the range of aggregate used in the specific conditions of work, the advantages acquired by the different ways of financing, technical elements, technological and organizational measures influence the required number of units of a certain type. They have been highlighted the working conditions and determined index of aggregate agricultural work: number of units, actual optimal load on the machine on which was set the deficit of machinery of the production unit under study.

Abstract: The increasing of cattle number from livestock ecosystems is a major objective in achieving feeding security of the human population. By the same time, the sustainable development of livestock is tightly linked to the protection, conservation and development of human useful animal species biodiversity.
In this study are presented the comparative results from specialty literature about cows breading, depending on the explotation technology and factors that influence milk production. By the same time, comparisons are made between the mode of cows maintenance at national and international level with existing conditions in Vrancea County in Romania, regarding the applicability of possible strategies of restructuration of explotation technologys for milk cattle, according to race, ecological zone, size of holdings and form of property.
 
Key words:  ecosystem, management, feeding security, holdings, biotechnology.

Abstract: Livestock production (milk, meat) depends heavily on reproductive activity, leading to scientific research and practice to find ways to optimize growth and livestock operation in order to achieve maximum economic efficiency. Research work in cattle reproduction, especially in family farms, are particularly important because understanding leads to increase capacity while the number of existing animals, meat and milk production, combating infertility, increased birth rates, increasing revenue and improving people's work throughout the year.
In the area of reproduction, these goals are of particular importance, both theoretical and practical, especially after the introduction and expansion of artificial insemination technique, a method that has transformed animal reproduction activity in a process managed and controlled entirely by man . It should be noted that the farm is the main basis of agricultural production, so it is necessary to highlight issues affecting the animal reproduction in the investigated area. Being holdings, taking into account recommendations made by the World Health Organization (WHO) and United Nations Food and Agriculture Organization (FAO) as well as those of romanian and foreign specialists in human nutrition.
In this regard, we calculated the main nonlinear regression of correlations analysis that exist between the LU and the most important factors that affecting increased production of milk cows in the South East and North East economic region of Romania.

Abstract: Currently there is a need to pay particular attention to the environment, the planet's non-renewable resources and man. Punctual, rural areas need an overall strategy on environmental protection and a specific strategy for sustainable development. Therefore, economic development should be based on appropriate strategies ecological limits provided by the planet by the environment.
Even rural tourism potential can be harnessed properly through various actions and multiple levels through collaboration of public and private responsibility. Priority should be those forms of tourism to save the planet's resources and avoid, whenever possible, waste generation.
Economic growth and sustainable development of tourism must be permanent, but safe and sustainable to meet the aspirations and needs of current and future generations.
 
Key words: sustainable development, environmental protection, economics, sustainable tourism,  tourism potential.

Abstract: The concept of sustainable development is relatively new in modern economic literature, he tried to translate as accurately as the English word „sustainability“. The debate on the concept of " sustainable development " have not yet led to a coherent point of view theoretical and methodological aspect , but the extent and intensity of organized provides an opportunity to lucid assessments of current models of economic and social development , located in an obvious conflicted with conservation of natural capital. Growth and development inevitably involves changes in ecosystems, and therefore economic policy development should be designed so that no rational harm the natural environment and the human factor, either now or in the future. We emphasize in this context that the effort to preserve natural capital is not intended to restrict the economic and social activity but to ensure its functionality as a prerequisite organizing and carrying out technical and productive processes. Thus implementation of an integrated quality management in rural tourism appears as a necessity to ensure sustainable development.
