The authors are the factors determining the increase in grain yields. Seeding technology during sowing determines the germination energy. The goal
was to increase the yield of crops by improving the design of double disc coulters. The analysis of existing double disc coulters to identify strengths and weaknesses in the formation of furrows and seeding the soil. To eliminate the identified shortcomings, it is proposed to equip the opener design with a fancy-shaped seeds pressing plate, which is moving in the groove formed by the opener, presses the seed to the bottom and aligns them on the depth of embedment, crushing and thus got to the bottom of lumps of soil. Encouraged to improve coulter design most fully solves the technical problem to meet the requirements of agricultural technology and enhances germination to 8%, and the yield of grain crops to 10%.
Keywords: furrow, two-disc coulter, curly seeds pinch bars, harvest. seed.
