The model of economic development of horticultural companies for determining the type of their economic growth was made. The following indexes of this model are suggested: income, cost price of fruit and berries production, the level of economic efficiency. The evaluation of horticultural enterprises over the research period (from 2010 to 2012) allowed to single out: eight companies with detensive development, characterized by deterioration of the technical and technological levels of production, they are those horticultural enterprises that gradually degrade; nine companies with extensive regressive development achieved by attracting additional financial and labour resources; nine enterprises were mainly with intensive progressive development which are characterized by increased production due to the rise of its efficiency through the introduction of science and technology achievements. It is necessary to introduce high-yielding and short-season varieties and expand planting the gardens on vegetative rootstocks for achieving the economic development of the company and maximize income in the field. Recommended high-yielding varieties of pome crops (apple trees) together with the allocation schemes of plantations, substantial investments and expenses, labour costs were laid in a matrix of the economic and mathematical problem in a package of Excel applications. The model of the problem involves 89 variables which imposed 121 restrictions. Optimal structure of the varieties of perennial plants for horticultural enterprises in Vinnytsia region was obtained in the result of doing the model. Yerlist-Geneva (49.6%) is recommended among summer varieties of perennial plants, Gala (46.3%) is of autumn varieties, among winter varieties there are Golden Delicious (11.4%), Jonaprince (10.1%), Re-varieties – Revena (9.3%), Relinda (9.3%), Renora (9.3%), Reanda (9.3%). Data of the modeling results indicate the possibility of horticultural enterprises not only increase the yield of fruit, but also reduce the cost price of sold production. Thus, by using recommended price for selling the products by specialists of Podilla’s Research Station Horticultural Institute and our offered structure of fruit plantations, the income increases by 1 centner and 1 ha, respectively by 13,0 and 54,4 times while the profitability is 355,9%.
