Purpose: The purpose of the paper is to presents two sowing machines for interval sowing, differing in the mode of operation. We were interested in adequacy of sowing at different working speeds of the pneumatic vacuum sowing machine OLT and the pneumatic pressure sowing machine Aeromat - Becker for sowing sugar beet. The goal of the paper is to find out the optimum working speed for the individual sowing machine. Design/methodology/approach: : In completely identical conditions at different speeds of sowing two sowing machines which are most widely used in Slovenia were tested. Findings: We measured and calculated the parameters such as working efficiency, depth of sowing, inter - row distance and distance between seeds in the sowing row. Research limitations/implications: For successful sowing it is necessary to know adequacy of the soil for sowing, technical properties of the sowing machine and biotechnical characteristics of the seed. Cultivation of sugar beet depends primarily on expert and technically correct sowing. For growth and normal development of plants the distance between seeds in the sowing row is the most important parameter. Practical implications: Expertly performed sowing and sowing machines are of great importance for cultivation of sugar beet. The tests were aimed at defining the most suitable sowing speed for both sowing machines on the basis of measured data. The principal aim of the paper is to establish whether the higher working speed influences the quality of sowing. It is very important for the producers to be well familiarized with all agro-technical measures because cultivation of sugar beet requires much money invested and work performed per unit of area. Originality/value: : The optimum sowing speed of the pneumatic vacuum machine OLT is 8 km/h and the optimum sowing speed of the pneumatic pressure sowing machine Aeromat - Becker is 10 km/h.
