摘要：Optimum size of the area destinated for agricultural crops is a actual subject in sustainable rural development strategies;most often presents interest to estimate a priori the areas used starting from an fixed capital,situations commonly encountered in allocation of funds practicing destinated to rural development projects. Mathematically, optimization models can have multiple starting points;here the optimization study is realized starting from the condition of using the fixed capital in amount S,originally established,strictly,for the entire production process,in case in witch there is no question of the existence of a minimum value of production. The proposed model is based on the restriction caused by the equality between initial fixed amount and product between optimal surface and the amount of fixed and variable costs expressed per unit area. It will be use a single factor production function,as a function of the second degree,which will express the dependence between production per unit area dependent by the variable expenses for fertilization soil. The original data are those from the 2013 agricultural year level.
