The article deals with a method for economically justified choice of machinery for the cultivation technologies of agricultural crops, cereal production being used as an example. The essence of the method is that minimum specific costs are determined for the discussed technological variants taking into account the amount of the performed work as well as the assessment of the selected tractor aggregate by the economical expediency of its operational width. Besides, the price of the tractor, its share related to a unit of the performed work is considered. The discussed technological variants differ by their technical equipment and the way the technological operations, such as ploughing, soil preparation and sowing, soil tillage without ploughing, separate sowing and loosening soil to a different depth, soil tillage with simultaneous sowing, are performed. The limits of economical efficiency of the discussed variants of soil tillage and sowing technology are determined depending on the amount of the performed operations.
