Quality of grain of spring wheat cultivated with the use of satellite navigation systems

The materials of this article show the results of determining the quality of grain of spring wheat cultivated with the use of satellite navigation systems in the Northern forest-steppe of the Tyumen region. The methods of application of mineral fertilizers and their impact on the yield of spring wheat, weight of 1000 grains, grain nature, glassy, quantity and quality of gluten are considered. The differentiated application of nitrogen fertilizers to the planned yield of 3.0 t / ha allows to increase the yield by 2.4%, the amount of gluten – by 8.9% and its quality – by 2.0% compared to the traditional method of application. The application of nitrogen fertilizers, regardless of the method of application, reduces the nature of the grain by 2-40 g/l relative to control. The weight of 1000 grains has an average relationship with the yield r=0,44 and a high degree of uniformity in the elementary areas of the field. The maximum grain vitreousness of 54.7% on the variant with differentiated application of nitrogen fertilizers in the off-line mode for the planned yield of 3.0 t/ha was revealed.
