YIELD OF SPRING RAPE AND BUCKWHEAT WHEN USING BROWN COAL FERTILIZER AND GLAUCONITE AGROMINERAL
The studied methods and non-traditional fertilizers contributed to an increase in the yield of buckwheat and spring rape. The most noticeable increase in the buckwheat grain yield was obtained in the variant with the introduction of brown coal at a rate of 5 t / ha - 19.6% compared to the background. With the combined use of coal in nanostructured form when processing seeds at a dose of 1.25 kg / per hectare sowing rate and NVGS of 0.4%, the average grain yield increased by 14.2% compared to the background. In the experiment with spring rape, the best indicator was also obtained with the integrated use of fertilizers - 12.6% compared to the background. The use of the studied materials had a positive effect on the chemical composition of grain crops: the content of nitrogen, phosphorus, potassium in buckwheat grain, the content of fat and protein in spring rape seeds increased.
