Growth and development of triticale culture in the Amur Region (Russia)

The paper presents the results of studies to determine the optimal density of spring triticale plants at different seeding rates in the southern agricultural zone of the Amur Region (Russia) in order to obtain an optimal grain yield. This crop is new for the Amur Region. It is considered more resistant to stressful weather factors and soil conditions and may become an important link in the production of feed grain in the region. The paper presents the results of field studies of the duration of interfacial periods of spring triticale. The influence of varieties and sowing rates on seedling density and field germination of seeds was determined, as well as the influence of varieties and seeding rates on plant survival. Also, the influence of different seeding rates on grain yield of spring triticale was studied. The paper provides an assessment of dynamics of the average grain yield of spring triticale depending on the seeding rate.
