This article describes the configuration and operating peculiarities of the combined opener for sowing grain crops with mineral fertilizer treatment at different depths. A comparative analysis of two sowing units was carried out: SKP-2.1 series seeder and SKP-2.1M seeder re-equipped with combined opener for mineral fertilizer application at different depths. Different variants of fertilizer application with different rates were studied. The influence of nitrogen fertilizer application method on the following performance elements of spring wheat was found: plant height, tilling capacity, the number of productive stems per unit area. Quality parameters of grain were defined: the content of protein and crude gluten depending on the method of sowing and the rate of mineral fertilizer application. Yield parameters were obtained when sowing using series and re-equipped seeders. Experimental studies revealed that the proposed opener provides mineral fertilizer application below seeding level. At the same time, the yield of cultivated crop and protein content in grain increased by 20 and 10%, respectively, in comparison with the technology of fertilizer application in the same soil horizon. Keywords—Opener, sowing, grain crop, mineral fertilizers, quality, yield.
