Abstract (English):
The optimum dose of fertilizer becomes a tool for creating a better yield structure, in which there is the most economical use of the batteries to create a unit of commercial products. The purpose of this research was to determine the impact of micronutrients (Cu, Mn, Zn) in the crop structure of winter wheat varieties Omsk 4 when cultivating on meadow-Chernozyom soils of Omsk region. Field experiments were conducted in 2007-2011 in the fields of Sibnica. In the topsoil the content of nitrate nitrogen and mobile phosphorus is average, exchange potassium is high, movable zinc, copper and manganese is low. Analysis of data on indicators of yield structure of winter wheat in the study of various methods of application of zinc fertilizers showed that zinc fertilizer had positive affect, i.e. productive tillering, grain number in ear and 1000 grain weight. Productive tillering in the best options of Р60Zn8 and Р60Zn100 was 9 units, the greatest number of seeds per head was formed on the best options for yield Р60Zn8 and Р60Zn100 was 40 Pcs, the weight of 1000 seeds in control was 42.3 g, the highest weight of 1000 grains was obtained from the use of dusting seed with zinc at a dose of 100 g/hectare for phosphorus background was 49.4 g. A positive effect on the structure of harvest is celebrated in the main application dose of 8 kg a. I./hectare of zinc at sowing and dusting the salt zinc sulphate in a dose of 100 g of salt per 1 kg of seeds. The number of productive stems, the greatest impact of manganese fertilizer in a dose of 100 g per kg of seeds increased up to 10 pieces per 1 m2. The 1000 grain weight was affected by best zinc and copper fertilizer in a dose of 100 g, where the figure was 45.08 g, and their combination (Zn50Cu50) was 45.80 G. In field experiments on meadow-Chernozyom soil it was established that plants of winter wheat positively responded to ap-plication of micronutrients. The structure of winter wheat crop was improved.
