Purpose: The paper presents two sowing machines for interval sowing, differing in the mode of operation. The pneumatic vacuum sowing machine OLT and the pneumatic pressure sowing machine Aeromat - Becker for sowing sugar beet are compared. We were interested in adequacy of sowing at different working speeds. The purpose of the paper is to find out the optimum working speed for the individual sowing machine. Design/methodology/approach: The measurements were performed with two sowing machines which are most widely used in Slovenia; the sowing machines were tested in completely identical conditions at different speed of sowing. Findings: The parameters such as working efficiency, depth of sowing, inter-row distance and distance between seeds in the sowing row were measured and calculated. Research limitations/implications: Cultivation of sugar beet depends primarily on expert and technically correct sowing. Distance between seeds in the sowing row must enable the plants to have optimum conditions for their growth and development. 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. Practical implications: Sowing machines and expertly performed sowing are of great importance for cultivation of sugar beet. The principal aim of the paper is to establish whether the higher working speed influences the quality of sowing. The test were aimed at defining the most suitable sowing speed for both sowing machines on the basis of measured data. Cultivation of sugar beet requires much money invested and work performed per unit of area. It is very important for the producers to be well familiarized with all agro - technical measures. Originality/value: Taking into account all measured parameters 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.
