RT Journal Article SR Electronic A1 Hejduk, Stanislav T1 The persistency evaluation of Czech varieties of Red (Trifolium pratense L.) and Alsike Clover (Trifolium hybridum L.) JF Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis YR 2014 VO 54 IS 4 SP 133 OP 138 DO 10.11118/actaun200654040133 UL https://acta.mendelu.cz/artkey/acu-200604-0016.php AB Red clover is the most important forage legume in the Czech Republic. It is an unassuming species to climatic and soil condition, is suitable for mixtures with grasses and it is above other grassland species in forage quality. The most serious problem of red clover in grasslands is its lack of persistency (2-4 years). Considering of red clover growing area on arable land decrease and area of permanent grasslands increases, becomes persistency of varieties important attribute. The persistency of all Czech varieties was evaluated on the basis of dominance proportion investigation after 3 winters. Assessed varieties were established in mixture with grasses (60:40%). Significantly most persistent varieties were Amos 4n (24.5%), Dolina 4n (20.25 %) and Radegast 4n (19.25%). Varieties of Alsike clover were not significantly different from varieties of red clover.
