Spring wheat seeds infection with different methods of basic soil cultivation

The aim of the study is to determine the infection rate of spring wheat seeds depending on different soil cultivation methods. The study was conducted in 2021-2022 at LLC Minderlinskoye of the Krasnoyarsk State Agrarian University. The soil is represented by leached heavy loamy chernozem with an increased humus content (6.1-8.0 %), pH 6.1-7.0. The degree of infection of spring wheat seeds was determined depending on different soil cultivation methods. The object of the study was spring wheat of the Novosibirskaya 31 variety. After harvesting, a phytosanitary examination of the seeds was carried out according to different experimental options. The infection rate of seeds with black germ was assessed on a 5-point scale. Also, the infection rate of seeds was determined during their germination in a humid chamber according to GOST 12044-93. Mathematical processing of the obtained data was carried out using one-way analysis of variance. The prevalence of seeds affected by embryo blackness ranged from 60 to 80 %. The intensity of development ranged from 26.3 to 35.7 %. Direct seeding resulted in accumulation of infection on spring wheat seeds, disease intensity increased by 9.4 % compared to traditional primary tillage.
