The best results were attained by pneumatic sowing machine and with sized seed. This characterises by the greatest number of sowing places in relation to regulated number of sowing places - 91.46%, great number of places with one seed - 97.08%, and great number of seeds on regulated distance - 58.89% which obtains the optimal vegetative space to a great number of plants. All these resulted in the greatest yield of 8,117 kg/ha. Pneumatic sowing machine and nonsized seed obtain 85.21% of sowed places in relation to regulated; 97.44% of places with one seed; 55.94% of seed which were sowed in regulated spaces; 52,765 plants/ha which resulted in yield of 7,552 kg/ha. Mechanical sowing machine with sized seed attained 85.24% of sowed places in relation to regulated; 88.10% places with one seed and only 31.14% of seeds sowed in regulated places with the yield of 7,365 kg/ha. Mechanical sowing machine and nonsized seed attained 84.14% of sowed places in relation to regulated; 82.14% places with one seed; 13.0% places with 2 seeds; 5.03% places with 3 seeds; 28.21% of seeds sowed on regulated space and with average yield of 7,660 kg/ha. With this combination of seed and sowing machine is attained the greatest number of plants per 1 ha, but the arrangement of these plants is not the most optimal. It is used more seeds which is not resulted in adequate maize yield.
