Improving technologies of soybean cultivation for the achievement of high and stable yield is a topical issue for the agro-industrial complex of Russia. The paper presents the results of a study on the influence of certain cultivation aspects on soybean yield under the monsoon conditions of Primorsky kray. The research goal was to determine the influence of the seeding rate and seeding methods on the yield of soybean variety Briz. The research object was new released mid-season soybean variety Briz created by Federal Scientific Center of Agricultural Biotechnology of the Far East named after A. K. Chaika. The plan of our two-factor experiment included the following variants: control; factor A (seeding method) – planting in rows at 15 or 30 cm spacing; factor B (seeding rate) – planting 300; 350; 400; 450; 500; 550; 600; 650 and 700 thousand seeds per hectare. The research established that the highest yield of soybean variety Briz (3.0–3.2 t/ha) was achieved by row planting with 15 cm spacing and by skip row planting with 30 cm spacing and a seeding rate of 350 thousand seeds per hectare.
