Abstrakt
It was found that southern ecotype alfalfa (Medicago sativa)
of variety 'Angelica' adapted to the soil and climatic conditions of the
Forest-Steppe and was not inferior in yielding capacity to variety 'Rosana'
which provided maximum indices in the phase of the beginning of budding
at sowing rates of 6.0 million pcs ha–1
and ordinary row sowing method
with row spacing 12.5 cm. It was discovered that with the increase of
alfalfa sowing rate from 4.0 to 8.0 million ha–1
the dry matter content of
varieties increased by 0.11–0.20% for sowing with row spacing of 25.0
cm. compared to row spacing of 12.5 cm. (22.62–22.83%). The average
crude protein content in variety 'Rosana' was 20.68–21.37 and 'Angelica'
20.67–21.07%. Narrowing of row spacing contributed to an increase in
crude protein content by 0.55–0.58%. The highest content NDF and ADF
were observed in the second year of alfalfa grass life, respectively 30.72–
34.91 and 23.02–24.60%. During the third year of alfalfa grass usage, the
indices decreased to 27.09–33.03 and 19.53–24.18%, respectively. Thus,
during three years of life at different geographical origins, alfalfa in the
phase of budding provided a stable dry matter output of 27.45–27.81 and
crude protein output of 5.86–5.87 t ha–1
for sowing with row spacing of
12.5 cm. and sowing rate of 6.0 million pcs ha–1.
