Evaluating harvested feed in the Vologda Region for the presence of nitrate compounds
The improvement of agriculture is inextricably linked with the increase in feed production. The intensive feed production system involves using high doses of nitrogen fertilizers. This significantly increases the yield, but at the same time nitrates accumulate in soil, water and feed. Excessive amount of nitrates causes the wrong course of functioning in natural ecosystems and animal organisms, there is a decrease in the biological value of products. Meanwhile, the importance of nitrates and their impact on human health has increased recently. However, this problem has not yet lost its significance and is increasingly attracting attention of many researchers of various specialties. Currently, there is no clear agreement on the permissible amounts of nitrates in feed for farm animals and on the effect of these toxicants on metabolism.

Productivity of variegated alfalfa after being treated with growth regulators in the Vologda region
Variegated alfalfa is a forage crop that occupies a leading place among perennial forage crops due to its multicut capacity, high yield of green mass and the nutritional value of the resulted feeds. The article presents the results of plant treatment with Biosil, Al’fastim and Emistim growth regulators. The effect of these preparations on the growth processes of variegated alfalfa and the increase of the green mass yield has been proved from theoretical and practical point of view. In the variant treated with Biosil, the average yield has been 44.9 t / ha, which exceeds the control variant without treatment by 4 t / ha. The yield of green mass in the variant treated with Emistim has exceeded the control variant by 2.1 t / ha and amounted to 43 t / ha.
