Productivity and nutritional value of pasture agrophytocenoses based on cereals and legumes
The paper presents the results of studying the influence of the species of perennial legumes and cereals on the productivity and nutritional value of pasture agrophytocenoses of the European North of the Russian Federation. The field experiment was started in 2017 and is still continuing. In the course of the research, it has been found that the most nutritious and highly productive, in comparison with the control variant, are the mixtures of legumes and cereals with the inclusion of festulolium or perennial ryegrass. The productivity of these grass mixtures is 8.7 t/ha and 8.4 t/ha, respectively, and significantly differs from the control variant.

Сultlvation of narrow-leaved fireweed (сhamaenerion angustifolium) together with maral root (rhaponticum carthamoides) (willd) jlin
The authors investigated the ability of narrow-leaved fireweed
(Сhamaenerion angustifolium or Ivan-chai) to grow together with maral root
(Rhaponticum Carthamoides) (Willd.) Iljin. in the Northern part of the non-chernozem
soil zone of Russia. Both plants were found to start grow immediately after melting
of snow cover. The phenological flowering period of the maral root occurs earlier than
that of the narrow-leaved fireweed. The experiment has revealed that in a mixture of
grasses, narrow-leaved firewood is being suppressed. In the third year of life there is
a thinning of the stalk of Ivan chai due to a drop in the shoot-producing capacity of its
roots. During the period of the experiment the productivity of the grass mixture was
lower, than in control version by 5 t/ha. In the control version, the metabolic energy
and raw protein collection were 11.2 GJ/ha and 179.3 kg/ha higher than in the grass
mixture. The maral root in the third year of growth develops a strong root system and
a leaf rosette, which results the unfavorable conditions for the narrow-leaved fireweed
(Сhamaenerion angustifolium) and it becomes obvious that it is displaced by the maral
root from the cenosis composition.
