Abstract
A well established structure of cultures at a level of area, county or farm, is an important factor for obtaining more stable average yields and closer to natural potential. Choosing the structure of culture must take account of the purpose (of the products meet nutrition for human and animal) and a number of restrictions imposed by the specific cultures. There have been developed several variants corresponding to different situations of resource allocation. The technical and economical indicators from the optimization model were based on the estimates of expenditure, the consumption norms of materials and labor, cost recovery and pricing of products analyzed. In respect of livestock by species and categories, they may correlate with the potential represents the county, depending on material, social and economic existence at a time. It requires increasing the areas cultivated with forage plants to meet the necessary volume of feed for cattle and sheep, at the level of expected livestock production.
