Modeling and Decision Making Applied to Agriculture

The study analyzed the variables that interfere in the choice of the soil cultivation system, using conventional and/or biodynamic agricultural practices for Vitis vinifera grapes production. The method was an exploratory and descriptive study of quali-quanti analysis. The intentional sample, for convenience and not probabilistic, had 26 vineyards of Vitis vinifera Chardonnay being 19 vineyards of the conventional cultivation system and 07 in transition to the cultivation system using biodynamic agriculture practices. It was concluded that economic variables are the driving force in decision making more than the environmental or social issues in the management of the cropping system, as well as it was noticed the tendency that some properties are looking for new cultivation practices. In the case of biodynamic agriculture, however, it is still tenuous signal that, in this case, the environmental issues could gain a greater value in equalization of alternatives for decision making in vineyard management and especially in soil care.
