Abstract: The study was conducted in 2011 "LYTAGRA" agricultural company, which, by the demonstration tests of winter wheat production Innovative technology for production of a competitive marketing farms (No. 1PM-PV-09-1-001504- je-liaus indeksag PR001) installation, implementation and maintenance procedures and conditions of the methodology equipped with a demonstration test. The investigation was found that the highest total yield of winter wheat crop was of densest culture. Compared with the least densest crop density, showed that the total crop yield was 5.7 percent and productive stems - 29.6 percent more. With increasing stand density was observed in the total crop growth and grain yield downward trend. Harvest index was 300 units m"2 density of the crop. A productive ear, 1000 grain weight and grain number per ear more less-common crops. Analysis of productivity components showed that the lowest density of crop productivity ear 38.1 percent higher than density crop. 1000 grain weight decreased with increasing stand density of 150 units m"2 compared with a crop density of 300, 450 and 600 units m"2 increased the weight of 3.6, 10 and 19.6 percent. Grain number per ear tend to decline, at least compared with the densest dense crop. This indicator is 150 units m"2 crop was 15.4 percent higher compared with the densest crop
