Forming of footstalks density of hulless barley in the conditions of southern forest-steppe of Omsk region

In the conditions of southern forest-steppe zone of Omsk Region on meadow and chernozyom soil in 2011-2014 the researches on forming of footstalks den- sity of hulless barley of the variety Siberian hulless 2 depending on the term of sowing, the norm of seeding and the background of chemicalization were conducted. By increasing seed rate from 3.5 to 5.5 million germinat- ing grains per hectare the share of germinating plants was reduced from 71.4 to 65.8 %. At sowing in the first ten-day period of June field germination was higher ascompared to sowing of the second and third ten-day period of May. The difference between options of chemicalization was within 68.0-68.9 %. The survivabil- ity of the plants on the average on the terms of sowing and norms of sowing without application of chemicals was 42.9 %, on the background of fertilizers and herbi- cides made 49.0 %, at the treatment with herbicides -50.9 %. Fewer plants were harvested in the option with- out using the means of chemicalization and more at using herbicides and fertilizers...
