Economic Effects of Using Geothermal Waters in the Production of Flowers and Vegetables in Glasshouses

Abstract Using geothermal waters in growing flowers and vegetables in the glasshouses represents the most modern form of production in sheltered areas, which enables the realization of a production cycle during the whole year, along with decreased energy costs. According to a study research, which was done in the area of South and East Serbia (first of all in the municipality of Vranje), in the paper were shown the economic effects of flowers and vegetables production, which can be expected by starting the production in modern glasshouses, along with the geothermal waters use. A basic goals of the research is to point out to peculiarities of flowers and vegetables production in the modern glasshouses, as well as to determine, based on the analysis of the gross reimbursement margin (gross financial result) in production of cut flowers (i.e. roses, gerbera and calla) and vegetables (i.e. tomato, cucumber and pepper), in which production line can be realized the best results. Accordingly, by making the analytical calculations based on the variable costs, was determined that the best results can be expected for roses (cut flowers production line) and tomato (vegetable production line).
