Influence of the method of application of fertilizers and seeding on the yield and the quality of spring wheat grain

An increase in the yield of cultivated crops is achieved through the introduction of new sowing technologies in agricultural production, which are based on the use of promising highly productive varieties, a balanced presence of nutrients in the soil and the provision of favorable conditions for plant root nutrition through the use of mineral fertilizers. Currently used agricultural machines do not fully meet the agrotechnical requirements for technological operations. Therefore, a need arose to improve the design of sowing machines, to develop a combined opener that provides sowing of seeds and fertilizing in different soil horizons and to conduct research to determine the effect of the method of applying mineral fertilizers on the quality and productivity of spring wheat grain. The article describes the device and the principle of operation of the combined opener for sowing grain crops with multilevel application of mineral fertilizers. A comparative analysis of two sowing units was carried out: a SKP-2...
