Dependence of seed productivity of spring rape Smilla on the method and depth of sowing in the Мiddle Urals

The results of studies aimed at the development of methods of sowing spring rape of the Smilla variety In the middle Urals are presented. The field two-factor experience was laid on the sod-fine podzolic heavy loamy soil of the educational and scientific experimental field of the FSBEI HE Perm SATU in 2016-2017. It was found that in the conditions of the Middle Urals, the highest yield is provided by agrocenoses, sowing of which was carried out by an anchor coulter, in combination with the depth of sowing 3 cm. the combination of these methods ensures the yield of 1.05 t/ha of oilseeds. Higher productivity during sowing with an anchor coulter is due to a large number of plants per 1 m2, preserved at the time of harvesting. When sowing with a single-disc coulter, a significant increase in plant productivity was noted, which is associated with the thinning of the stem. The reaction to the deepening of seed placement was noted only in variants using an anchor coulter. Increase sowing depth of 3 cm compared with more shallow placement of seeds was 0.11-0.19 t/ha. Seeding double-disk opener offset by the difference in the study of seeding depth. The data of the actual yield of spring rapeseeds are confirmed by the indicators of the yield structure.
