We carried out the research in 2020 under conditions of unstable moistening on ordinary chernozem of the Western Ciscaucasia (Korenovsky district, the Krasnodar region) to study the effect of different seeding rates (providing plant density of 40, 60, and 80 thousand pcs/ha) on the productivity of a new mid-ripening hybrid of sunflower Arneb of the breeding of V.S. Pustovoit AllRussian Research Institute of Oil Crops. We established that an increase in the seeding rate of seeds from 40 to 60 and 80 thousand pieces/ha led to a decrease in productivity – from 2.77 to 2.76 and 2.66 t/ha and oil yield – from 1.12 to 1.10 and 1.07 t/ha, respectively.
