Comparative productivity evaluation of meadow clover (trifolium pratense l.) different varieties in the Vologda region
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).

The effect of adding perennial grasses of the second mowing to the flattened spring barley grain for its storage in air-tight conditions
The article presents the results of studying the addition of green mass of grass to the flattened spring barley grain. Finely chopped grass is an effective means of accelerating the creation of anaerobic conditions in the grain mass and reducing the loss of dry matter during storage. It was revealed that as a result of the addition of grass, the period of creating oxygen-free conditions had been reduced to two or three days, the loss of dry matter during this time had not exceeded 1.5-2.5%. The optimal dose of grass has been 3% of the grain weight. Dry matter losses at this dose amounted to 4.8% for the period of 30 days of storage, in the mass of grain without grass the losses reached 11.3%.
