On backgrounds with no fertilizers, the field germination rate of the crop averaged 68.6% and 68.9%; it decreased to 68% at a fertilized background. Minimum germination rates were when sowing was on May 25th-28th; maximum – when sowing was on June 4th-6th. When there is an increase in the seeding rate, the field germination decreases. The ratio of weeds in the control variants averaged 25.4The cultivation technology elements of hulless barley were studied at the experimental field of the Omsk State Agrarian University, including 3 chemicalization backgrounds: without chemicalization, with herbicides (Puma Super 7.5 + Sekator Turbo) and with herbicides + fertilizers (ammonium nitrate N60); 3 sowing dates: May 14th-18th, May 25th-28th, June 4th-6th; 3 seeding rates: 3.5, 4.5 and 5.5 million germinating grains per hectare.

The ratio of weeds in the control variants averaged 25.4%, herbicides reduced the weed ratio to 3.9 – 8.2%; the effectiveness of herbicides at a fertilized background was lower. The weed ratio decreased from the early to later sowing dates and as the seeding rate increased. In plots without chemicalization, the weight of one weed plant was 1.80 g, in variants with herbicidal treatment – 1.91-1.92 g. It reached its maximum value on crops that were sowed at the third decade of May. The weight of one cultivated plant at a background without chemicalization was 3.89 g, at a background with herbicides – 4.44 g, at a background with fertilizers and herbicides – 5.03 g; an increase in the seeding rate led to a decrease in the weight.

As the seeding rate increased, the viability was reduced. Thus, the optimal conditions for the development of barley plants in agrophytocenosis were formed at the background of the use of nitrogen fertilizer (N60) and spraying of crops with a mixture of herbicides Puma Super 7.5, oil-water dispersion and Sekator Turbo, oil dispersion.
