Sowing if one of the key operations in the technology of cultivation of grain crops. Analysis of existing studies show that the most important reserve for sustainable grain production is the introduction of new methods of sowing, sowing machines and their working bodies. In modern conditions, resource-saving sowing technologies are widely used. In resource-saving technology, high-quality sowing characterizes the uniformity of seed distribution over the feeding area and the seeding depth, considering the soil and climatic conditions of Buryatia. In studies on the agronomic justification of sowing methods, the influence of row spacing, distribution uniformity and uneven sowing of seeds on the yield of spring wheat of the local variety “Buryatskaya-79” was studied. At the same time, comparative tests of serial and improved coulters of seeders of the SZ type were carried out. It was revealed that in the dry steppe, with a seeding rate of 4-5 million grains/ha, a row spacing of 7.5-15 cm is allowed, with 3 million grains/ha - 45 cm; with a row spacing width of 45 cm, there is an increase in separate harvesting losses; uniform seed placement during strip sowing has significant advantages compared to the usual row seeding method with the existing seeding rate.
