Sowing and technological qualities of seeds, depending on the time of sowing, seeding rate and background of chemization rate were determined on crops of oats of variety of the Siberian hull-less oat produced in the meadow black earth average power low humus medium loam soil in 2011-2014. Seeding rates and chemicals did not have any considerable influence on the energy of germination (on the vigor). The change of this index depended on the term of sowing. The seeds of early term of sowing had the germination energy 7.8-11.0 % higher as compared to the late terms of sowing. The influence of term of sowing on the determination of the laboratory germination was also marked. The germination of seed from sowing of the second ten-day period of May varied from 96.3 to 97.3 % depending on the background of chemization, and sowing in the first ten-day period of June there was a decline by 3.0-4.9 %. Between variants of sowing norm study the indexes of laboratory germination did not have any considerable divergences. The most part of mass of 1000 seeds formed at top-dressing and the treatment with herbicide and made 31 g, at treatment the agritox only the mass of seeds was less than 0.4 g, and from a variant without treatment it was 0.8 g less. The use of chemicals contributed to the increase of the grain from 444 g/l from the control plots to 467 g/l to crops, where the herbicide was applied, and 475 g/l, where the fertilizes were top-dressed and the lot of land was sprayed with herbicide. The protein content in the grain of hull-less oats on the background without the use of facilities of chemization was 14.11-14.85 % on the average for four years. Adding of the ammonium nitrate (ammoniac saltpetre) in combination with the herbicide treatment increased the protein content by 0.51 % as compared to control data. A quality of hull-less oats seeds depended on the time of planting, nitrogen fertilizers and herbicidal (weed-killing) treatments.
