A combine U-shaped furrow-opener for laying and seeding crops and granules of mineral fertilizers with their multi-level application is presented. The research technique for substantiating the optimal parameters is presented. The results are determined on the basis of laboratory and laboratory field studies. The optimal design parameters of the combined opener with a U-shaped furrow were revealed: the width of the bed compactor is 13.1 mm, the distance between the planes of the outlet holes of the needle guide and the vas deferens is 35.4 mm, the distance from the base of the exit hole of the needle guide to the U-shaped furrow is 48.7 mm. The average traction resistance of the seeder was 13,325 N when the tractor moved in the VI gear. The distribution of seeds along the length of the row with the dual-level opener is 74.2%. The depth of seeding crops with an experimental seeder and a serial corresponding one was 49 ± 3 mm and 51 ± 5 mm. The soil layer between the seeds and fertilizers was 25 ± 3 mm.
