BIOMETRIC INDICATORS AND PRODUCTIVITY OF ALFALFA VARIETIES IN THE VOLOGDA REGION

Abstract

It is currently impossible to develop the agro-industrial complex without
creating a solid fodder base in order to provide cattle with high-protein feed. One of the urgent tasks of agricultural production is to increase the yield and protein nutritional value of
alfalfa, which is of great importance in filling the fodder base. Alfalfa (Medicágosatíva) is a
protein-rich crop that can produce from 2 to 4 cuts in summer with herbage productivity of
250.00-300.00 dt/ha. Without the main nutrients (N, K, P), the plant cannot develop fully, in
connection with this, their introduction from year to year increases the productivity of the
crop by 3-4 year of use. The experiment to study the yield and biometric indicators of alfalfa
varieties was carried out in 2019-2020 on the scientific-experimental field of Vologda State
Dairy Farming Academy by a field experiment. The experimental data show that the yield of
herbage of the studied varieties of Medicágo in the climatic conditions of the North-West was
55,50-64,90 t/ha. As for the yield of dry matter with herbage yield, it was from 10,50 to 15,50
t/ha. Varieties Vega 87 and Taisiia turned out to be the best of the experimental varieties in
terms of dry matter in herbage yield per hectare from 13,60 to 15,50 t/ha, with an average of
13,18 t/ha for varieties. To a greater extent, the studied indicators of Medicágo biometrics depend on the characteristics of plant adaptation to living environment, development and reproduction, as well as climatic conditions during the growing season of the studied varieties.
