Influence of the evenness of seeding using a disk-cell seeding mechanism on the productivity of scarlet amaranth

Abstract

The paper presents the results of a field study of the effect of the evenness of seeding using a disk-cell seeding mechanism on the fresh yield and Scarlet amaranth grain of Kinelsky 254 variety. The problem of the amaranth evenness of seeding was solved by developing an experimental seeder of precision sowing for small-seeded crops. Field experiments were carried out on the fields of the Volga Research Institute of Selection and Seed Production named after P. N. Konstantinovin 2019-2021. To control the qualitative parameters of sowing, amaranth was sown with ballast (blind seeds) with a VS-4.2 vegetable seeder. The study revealed that the evenness of seed distribution in a row during sowing with an experimental seeder was 22%, for plants – 24.6%, control – 24.6 and 72.1%, respectively. The use of an experimental seeder made it possible to sow in accordance with agrotechnical requirements and create the best conditions for plant nutrition, which led to an increase in the fresh yield of Scarlet amaranthof Kinelsky 254 variety by 2.6 times, grain – by 1.6 times.
