Botanical composition and quality of feed when using grazing herbs with festulolium

The results of 14-year studies on the botanical composition and quality of grazing feed using herbs, created on the basis of the domestic variety of festulolium VIK 60, are presented. Experimentally substantiated promising grass mixtures in the composition of the festulolium, cocksfoot and bluegrass meadow.

Hybrid of meadow fescue "VIK-5-34" for growing on high agrophones on meadows and pastures in the European part of Russia

Meadow fescue is one of the best grasses for forage production in most of Russia, being inferior in productivity to pasture ryegrass in the country's reserve; it is much superior to it in other regions in terms of longevity, sea resistance and drought resistance. This species is also less affected by fungal diseases, grows well in herb mixtures with both clover and alfalfa or with other legumes and cereals. The new variety "VIK-5-34" is intended for cultivation on high agricultural grounds in farms with a high level of agriculture. The variety can be used both for foraging and for creating pastures.

New narrow-leafed lupin variety Belorozovy 144

The article presents the description of a new feed middle-ripening narrow-leafed lupin variety. Its vegetation period takes 88–103 days. The average grain yield is 25–30 cwt/ha, the potential one — 40 cwt/ha. The average green mass yield is 340–400 cwt/ha, the potential one — to 6000 cwt/ha. The content of grain raw protein is 33.0–36.0%; the alkaloid content is 0.027–0.050%.

L3 — a new innovative variety winter vetch for the Ural and Central Chernozem regions of Russia

Winter vetch, shaggy provides high-protein animal feed in the spring on complexes, food from this plant is perfectly absorbed by all domestic animals. The new variety of winter shaggy vetch "L3" surpasses the existing varieties in the productivity of green mass, dry matter, and seed productivity. In terms of protein content, this variety is not inferior to most varieties. The variety is recommended for two regions, but later zoning can be expanded. The variety is also characterized by high winter hardiness and drought resistance.

Economic efficiency of creation and long-term use of different-ripening grass stands for hay harvesting

Based on the improved methodology, an economic assessment of the mowing technology for hay harvesting is given. The total cost (44.8–47.5 thousand rubles/ha) for the creation of early and medium-mature long-term herbage with the dominance of rhizomatous grasses paid off in 1.6–1.8 years. In the next 25 years, annual production costs amounted to 20.1–21.6 thousand rubles/ha with the cost of 1 feed unit of 5.1–5.6 rubles and a conditional net income of 15.1–20.1 thousand rubles/ha.

Variable world of the nutritionist N. P. Volkov

Article is devoted to life and creativity of one of outstanding representatives of a zootechny of the XX-th century — to Nikolai Pavlovich Volkov. Well-educated (the zootechnician, cyberneticist, economist), he is the author of the unique project — variable norms of cattle feeding. It considers concrete conditions of economy, age, productivity, physiological state of animals, conditions of livestock keeping, a season of year, actual availability and quality of forages. After a semi-centennial period a factorial method again has been used by workings out of norms. Volkov’s original views on topical questions of a science and production are stated: about fodder analysis, effective means of grain processing, aminoadducts theory, the advisory help to farms of experimental base of Williams fodder institute, which stuff keeps in mind the creative work of well-known scientist Nikolai Pavlovich Volkov.

Efficiency of fertilizer application on seed stands of birdsfoot trefoil

On sod-podzolic medium-loamy soils of the Central Non-Chernozem region of Russia with an average availability of mobile forms of phosphorus and an average close to low potassium content, high efficiency of using potash fertilizer together with phosphorus on birdsfoot trefoil seed crops was established. Effective doses of phosphorus-potassium fertilizers, providing an increase in seed yield in the first year by 42–47% and, according to the aftereffect, in the second year by 17–33%, are the application of P30–60K90–120. Keywords: Birdsfoot trefoil (Lotus corniculatus L.), seed herbage, phosphoric and potash mineral fertilizers, yield, seeds, sowing qualities.

FORMATION OF BICARPIC POPULATIONS OF BLACK MEDIC

15 populations of black medic (Medicago lupulina L.) of various ecological and geo-graphical origin were studied by the type of ontogenesis. It was found that 1 population is represented entirely by monocarp forms of plants, 7 populations have 20–60% of mono-carps. Wild alfalfa from the Moscow region and mutant forms created on its basis consist of 100% bicarpic plants. Bicarpic plants of varieties Georgia, Nordol, Rinata and selection number LH19-3, whose average dry matter productivity was 40.8–48.0 g/plant, are valuable as a source material for breeding of black medic. As sources of high seed prod-uctivity (10.0 and 10.3 g/plant), you can use bicarpic plants of the selection number VIK 256 and Georgia varieties, and high leafed (52.4 and 55.3%) — selection numbers DS-1 and VIK 61/94.

Variability of fodder value of collection samples bentgrass

The peculiarities of the manifestation of variability and interrelationships of feed quality indicators in 27 genotypes belonging to three types of bentgrass were studied. A significant level of genotypic variability in the content of crude fat, crude protein, ash, phosphorus and potassium was revealed. Taking into account the low level of variability depending on the conditions of the growing year, it is recommended to pay attention to the crude fat content, crude fiber content and plant height when selecting. It is recommended to determine the genotypic divergence of genotypes when selecting parent pairs for hybridization using cluster analysis methods.
