There is an uptake of neccesar resources from environment to obtain products. Taking into account that this issue takes place under knowledges application, interrelation with environment, the farming could contribute to environment preservation, if rationally practics is applied, with no „pressures” on it, as follows of intensivity (huge factory concentration per area unit and caution in their utilization). At the same time, the performance as ecological results, is achieved by crop structures which involve branches with adaptability to environment and respond to modifications of human consumption pattern. The economical performance of field exploitation could be approached only from a certain level of yields and their costs. Generally speaking, the performance is the quality of human activity to produce maximum useful effects, for individuals and society, with minimum expenses. All theses focus to the quantitative aspect and, generally, to economical size of human activity. To be efficient is not entirely meet the social, situation achieved only by the concept of sustainable development. The large number of diversified documentation sources as well as the utilization of investigation method performed at farmers have allowed knowing of current level of technological development and impact of reality on performances registered by crop exploitations. Based on this, new opportunities have been created to economically increase the Region. The application of linear programming pattern to improve the yield structure required data and evaluations, which refer to: existing total area (arable land), crops available to using category, available financial resources, expenses per crops, input necessary (chemical and organic fertilizers) per crops and availability from these resources. The study represents the complex analysis of area capability to produce value and to preserv the environment, having as evaluation criteria, the yield diversification degree. By diversifying cultivated species, one can follows the gradual determination of eco-economical performance, taking into account the possibilities for their commercialization on market. The obtained variants will
constitute the possible options for decision-makers. Although by design process, the increasing of economical efficiency is desired, it is necessary that the indicator system must be correlated with realities and requirements of competition economy. Having in view the influence of size structure on yield and economical results, it is necessary to modify the cultivated areas; this allow the mechanization and obtainment of high benefit per ha, increasing in exploitation specialization for crops which meet the best conditions for yielding and selling. The concentration and yield development in the South Muntenia Developmental Region could generates suddenly positive effects on economical and social plan; the place of benefit into all factors of production dynamics cannot be changed.
