The design-technological scheme and design of the combined opener for laying and embedding of seeds of grain crops and granules of mineral fertilizers at their multilevel application have been substantiated and developed. It has been substantiated that the most urgent is the sowing of grain crops with simultaneous multilevel fertilization below the sowing bed with the formation of a soil layer, which ensures uniform distribution of seeds and fertilizers over the area of application and allows the most rational use of mineral fertilizers and reduce labor and production costs for production. The technique of researching the technological process of multilevel fertilization and sowing of seeds is presented. The results are determined based on theoretical research. The values of design parameters have been determined: the width of the bed seal (7 ... 25 mm), the distance between the planes of the outlet of the guide and the seed tube (20 ... 80 mm), the distance from the base of the outlet of the guide to the U-shaped harrow (40 ... 50 mm).
