The influence of constructive and technological parameters of these sowing apparatuses on the sowing completeness and uniformity is substantiated. The mathematical model of precise sowing the seeds by means of a disc apparatus to determine the power and velocity of extrusion of grains out of cells and to determine the kinematical and constructive parameters of seeds - layer is developed. The analytical dependences of the process of filling the cells of disc sowing apparatus with seeds depending on the material mass in a bunker, the speed of rotating of the sowing disc and other parameters is investigated. The education of regression of dependence of completeness of sowing the seeds of sugar - beets and peas on seven factors is developed. The results of laboratory researches and tests of disc mechanical APSS proved the completeness of sowing the seeds of sugar - beets and mangel - wurzels of different fractions 95%...98%, at the same time the mass of sowing apparatuses decreased 32…40% The stand to investigate the characteristics of sowing apparatuses and disc APSS with the removable discs and sells for sowing the covered and uncovered seeds of beets and peas. The annual average economic effect of using only one such apparatus is 1034,89 hrn.
