A model for locating grapevine varieties on an area of 103,74 ha (Southern wine growing region, Republic of Moldova) is described in this paper, focusing on field sizing within the limits of 4.5-35 ha. In addition to the 13 main variables reflecting the surface planted with one or another vine variety, the economic-mathematical problem also included the variables that determine the surface planted with table grape varieties (x14) and the technical ones (x15) and also other two variables (x16, x17) which allow to establish the need for normalized financial investment and consumption. Together with other restrictions, the numerical model included restrictions regarding the limits of field size. As a result of the project implementation, it is expected to produce 1051 tonnes of grapes or 313 tonnes of table grapes and 738 tonnes of wine grapes, respectively. After the commercialization, the profit will be 2.146 million MDL constituting a profitability of 124 %. The investments allocated for grapevine planting and management, until the vineyard start to bear fruit, will be 9,725,000 MDL, while the financial normative consumption will reach the figure of 1717 thousand MDL. The developed model can be used by the grape growers in the Southern wine growing region for fields sizing, choice of variety and increase of profits.
