Abstract
Field experiments were carried out on sod-podzolic medium loamy soil, typical for the Northern region of the Russian Federation, in 2012-2019. The dependence of spring oat yields on abiotic conditions was studied. During the research years, the weather conditions varied significantly, which affected the productivity of spring oat. The yield of spring oat grain was found to have a very weak correlation with the effective temperature sum, weak correlation - with the total precipitation, and negative correlation - with the mean air temperature, which indicates the possibility of seed production of this crop in the Northern region of the Russian Federation. According to the data obtained, grain yields varied significantly from year to year. The reasons for the decline in grain productivity in individual years were different and complex. The most plastic cultivars with high productivity were identified.
