In 2011-2014 years on a small experimental field of Omsk State Agricultural Academy on meadow chernozem of medium-heavy low-humus medium-loamy soil the studies were carried out to study the influence of sowing time and chemicalization means on the sowing and technological qualities of hull-less barley. Omskiy 2 variety of barley was sown, which is characterized by an increased content of fat and lysine. Three terms of sowing were studied (2nd decade of May, 3rd decade of May, 1st decade of June) and three backgrounds of chemicalization (without chemicals, herbicides, herbicides + fertilizers). The energy of seeds germination, obtained from variants without chemicals, was 88.7%. When treating herbs with herbicides, this indicator increased by 1.7%, when nitrogen fertilizers were introduced, it decreased to 85%. Regardless of the chemicalization background, the germination energy decreased from the early sowing period to the late one, from 91% at the first sowing period, to 89.7% at the second and 85% at the sowing in June. The analysis of laboratory germination showed insignificant changes between the variants. On the background without chemicalization means, the germination capacity was 95%, while cultivating a tank mix of herbicides, the germination rose to 1%, with the application of fertilizers and herbicides to 0.6%. A slight decrease in germination occurs when the sowing period changes from early to late to 0.4 and 1.1%. The largest mass of 1000 seeds was observed in later crops, when fertilizers were applied and herbicides were treated with 33.68-33.98 gram, against the background of herbicides of 33.34-33.84 gram, without chemical means of 32.67-32.95 gram. Higher values of nature were recorded in the grain, obtained on the background with the use of herbicides and on average in terms of sowing time were 602.7 gram per litre; on the background of fertilizers and herbicides of 596 gram per litre; without the use of chemicals 587.7 gram per litre. Depending on the seeding time, nature was reduced from the early sowing season to the late one (from 613.7 gram per litre to 575 gram). The protein content in the grain when spraying barley crops with herbicides is higher to 0.3%, with the addition of nitrogen fertilizer to 1.02%, compared with the variant without chemicalization. When sowing in the second decade of May, the protein content in the grain of barley is 15.61%, when sown for a decade later, there is a decrease to 0.06%, for two decades to 0.27%.
