As a result of the analysis, it is summarized that the change in the price of land is mainly associated with the change in the land rent paid in the country. The price of agricultural land in the country is significantly lower than in a number of European countries, but this is not the case for the land rent paid, which is close to the European average.

Previously in the works of Plato, Xenophon and others it was mentioned but not used as a term. With the entry of capitalism into agricultural politics - everyone talks about it. Agriculture became the main branch of social production, and rent became the object of study. Contribution to the development of the problem have: У. Petit, Fr. F. P?ti, F. Kenet, A. Smith, D. The work of Marx is indisputable. The neoclassical theory advocates a subjective treatment of the problem -opposed to Marx. The reasons are to be sought in the following circumstances: capitalism has undergone fundamental changes; it has entered a stage of global integration; the scientific-technical revolution has raised it to a greater height; new technologies have entered the economy; electronization, robotization, computerization, science has penetrated all spheres of life, has become an immediate productive force; it is rising to a higher level; production is being naturalized, it is becoming a field of application of science. History, however, follows its own logic. The immature economic forms of production do not submit to exact theoretical reflections; as they change, so do our ideas about them.

In our country, for many years, there have been long traditions in the production of cereal plants and oilseed crops. In Northeast Bulgaria - General Toshevo region, in 1951, Dobrudzha Agricultural Research Institute was established, which is known today as Dobrudzha Agricultural Institute, and it performs selection in the field of wheat varieties and sunflower seeds production. The agricultural land in Bulgaria is cultivated and cropped with seeds of high quality, which results in good harvest of cereals and oilseed crops. The chief purpose of this paper is to establish the indicators that can guarantee a sustainable use of the land resources in our country for production of cereal plants and oilseed crops throughout a long period of development and to analyze the dynamics in the process of their use.

Possibilities have been identified to distinguish the business from other market participants and to better position it on the market through cost leadership or differentiation of product quality. An analysis has been conducted of a product differentiation method applying five factors facilitating the positioning of the brand to achieve better satisfaction of consumer preferences and earn the consumers' loyalty. It was found that in the examined product category the factor contributing to the greatest degree to product differentiation is the adopted assortment policy.

Pastures are the subject of agronomic, zoos engineering and economic research, which report negative trends in their territorial scope, composition and productivity as a whole. In beef cattle breeding, the long-term goal is to use high-productivity pastures, which will increase the yield of meat from them, because poor pastures require feeding the cattle with other feed, which reduces profitability.
