Karpuk L. Sowing qualities and productive properties of sugar beet seeds of depending on the methods of their preparation

The adjusting of the modes of sugar beet seed's polishing by the change of frequency of current from 35 to 50 Hertz substantially did not influence on the polishing degree and on their physical and mechanical properties. It is set, that on the polishing degree influence loading on a polishing machine substantially, that predefined sometimes finding of sugar beet seed's and by their amount in a drum. It is set that at all modes of polishing rise on sugar beet seed's intensity of germination substantially. The seed's sorting according to the aerodynamic properties of sowing factions 3,5-4,5 and 4,5-5,5 with the purpose to increase the monogermity is not effective. During the study of the biological features and productivity of the MS of sugar beets according to the methods of the seed's preparation. It is set, that sugar beet seed's intensity of germination, field likeness of the seed, the density of plants, the productivity and the harvest of the sugar from one hectare is determined direct dependence on the methods of their preparation.
