In Latvia oat sowing areas are changing depending in the year, but the data of recent years show an increase by about 54 %. Various oats are used as animal feed, but due to their high nutritional value the use of oats in food production has increased. The suitability for the particular use is determined not only by agronomic and annual meteorological conditions, but also by a variety. To test and evaluate the suitability of different varieties for growth in Latvia, several oat varieties were sown and analysed annually in Institute of Agricultural Resources and Economics – Stende Research Centre. In from 2019 to 2020, 16 oat varieties (selected in different countries) were used for the comparison. The indicators determined were as follows: grain yield (t haE−1), volume weight (g LE−1) and TGW (g); as regards biochemical indicators, they were crude protein (%), fat (%), β – glucan (%) and starch (%) content. Meteorological conditions in both years were optimal for the growth and development of oats. Comparing the yield data of oat varieties, statistically significant differences (p is less than 0.05) should be noted between vegetation seasons (RS0.05 = 1.44), yield varied form 7.4–9.9 t haE−1. Difference between volume weight was significant (p is less than 0.05) between varieties (RS0.05 = 16.50), ‘Bison’ (562.3 g LE−1) and in 2020 ‘Scorpion’ (556.3 g LE−1) had the highest volume weight in 2019. During the period of two years three varieties, i.e., ‘Bison’, ‘Harmony’ and ‘Ivory’ were notable as varieties with the highest commercially important indicators.
