Abstract:
The purpose of this paper is to promote the setting up of farms whose size will allow the practice of a viable, sustainable
agriculture, capable to apply the newest technologies and lead to profit and efficiency, to the economical and
organizational consolidation. The essential criterion in optimizing the crop structure is the economic efficiency,
respectively the realized profit. Economic efficiency is constantly changing due to changes in raw material prices and
commodity production. Hence the need to optimize the structure of crops in each cycle of agricultural production. The
main indicators used in optimizing the structure of crops are: yield per hectare, production costs per unit area, profit per
hectare, unit cost and rate of return. As a consequence, the resizing of the agricultural holdings, the partnership between
the producers, the integration of the agricultural production, the rural development, the consumers’ constant request for
agricultural and food products, the decrease of the deficit of the commercial balance for the agricultural products, the
increase of the population’s life standard, the safety of the food, all these are goals that have to be under the continuous
attention of the authorities at central and local level. The elaboration of mathematical models was oriented on the design
of several structural alternatives and the elaboration of a large number of variants, because analysing the problem of
establishing an optimal structure through the prism of several variants creates the possibility of highlighting the
development and manifestation of different phenomena, some conclusions, not by subjective assessments or by
antithesis, but on the basis of several concrete structures that each variant covers.
