Abstract
Red clover is the main perennial legume crop in the Northern region. The article presents the results of the competitive variety testing of accessions (2019 and 2021) on nutritional value and feed productivity. Amounts of crude protein, fat, fiber, sugar, ash elements and carotene were estimated in contrasting meteorological conditions. The research years had signifi differences in the sum of temperatures, precipitation accumulation and hydrothermal coeffi During ‘regrowth-beginning of fl period of red clover, the hydrothermal coeffi was 2.2 in 2019, and 0.75 in 2021. The purpose of the research was to study the nutritional value and productivity of breeding samples of red clover and selection of promising ones for further breeding work. The prevailing role of weather conditions over the varietal features of samples was revealed. In the dry year 2021, the studied indicators of nutritional value (except phosphorus) were higher than in the wet year 2019. In terms of nutrient content, SD-326, K-17421, K-46524, K-44964, K-1939 were identifi signifi exceeding the standard or showing a result at the standard level for two or more chemical components. In terms of high nutritional value and protein yield, three samples reliably confirmed the excess over the standard on average for two years of testing: SD-326-1227 kg/ha (+ 130 kg/ha), K-17421-1308 kg/ha (+ 211 kg/ha), K-46524-1156 kg/ha (+ 59 kg/ha). The obtained results will be used in future creation of red clover cultivars with high nutritional properties and feed productivity.
