It was found that the highest hay yield compared to the standard Trio

variety was observed in the Taezhnik variety (105.3 C/ha) in the conditions of the

Vologda region on sod-podzolic medium loamy soil for 2017-2019. The variety to

control provided a significant increase in yield of 15.9 C / ha (18%). The Allure variety

showed a significantly lower yield compared to the standard (17 C / ha, i.e.19%). The

rest of the studied Ranniy-2 and Roseta varieties provided the yield at the standard

level. The tested varieties of meadow clover showed good and almost excellent winter

hardiness which is 4-4.7 points. The content of “raw” protein exceeded the control

grade of Ranniy-2 (by 1.2%), Taezhnik (by 0.9%), Allure (by 0.5%). For the collection

of “raw” protein with a yield of green mass, the Allure and Roseta varieties were inferior

to the standard by 153 and 11 kg / ha. Ranniy- 2 and Taezhnik varieties provided the

collection of “raw” protein with a green mass yield of 1155 and 1245 kg/ha, respectively,

exceeding the standard by 173 and 263 kg / ha. The average and large correlation of

such indicators as the yield of clover varieties and plant height from r = 0.551 to r =

0.743 was revealed. A weak relationship was established between such indicators as

leafiness and yield (r = 0.434 – 0.525), yield and protein content (r = 0.451), protein

content in the green mass and plant leafiness (r = 0.448).
