Blagoveschensky G. V. Innovative potential of the leguminous sward diversity


УДК: 633.31/.37

The swards’ productivity can be increased via extending the variability of leguminous component in mixtures. Improving and maintaining the swards’ feed value allow expanding protein output and levelling down soybean import for milk and meat production in Europe. Legume cultivation provides a 2.5–3.0 times’ decrease of nonrenewable energy expenditures, due to the rhizobial nitrogen fi xation. Maintaining the legume’s share of 30–50 % can be optimal for dry matter yield, high feed value and good palatability, as well as minimize nitrogen emissions.

Keywords: leguminous grasses, grass mixtures, usage prospectives.

Yu. N. Eremina, Gvozdeva K. I. Vasily R. Williams: an outstanding scientist of his time


УДК: 631/635 (092)

The biography of V. R. Williams is closely related to the history of Petrovskaya, then Timiryazevskaya agricultural academy. A number of independent departments and research institutes have evolved from his department, and not only within the Academy. He undertook a minute study of the USSR’s soils and agriculture; before the revolution he has been on numerous expeditions across the country, and he was familiar with the nature of the agricultural areas of the USA and Canada, France, and Germany. The elements of the grassland farming system developed by V. R. Williams, which expand the recovery of the soil fertility, are found in the modern technologies.

Keywords: Vasily R. Williams, soil science, grassland science, grassland farming.

Perepravo N. I., Trukhan O. V., Ryabova V. E. Scientifi c basis of the shortgrasses’ seed production


УДК: 631.2/.3.03:631.531.

The scientifi c basis of formation is developed together with the energy-efficient, ecologically safe techniques for cultivating and harvesting highly productive agricultural phytocenosis of shortgrasses for seed use. They are built on studying the development biology of the crops, blooming and seed formation peculiarities, determination of the optimal structural indices of the seed swards dependent on the soil and climatic factors.

Keywords: seed production, forage crops, swards for seed use, shortgrasses, environmental management.

УДК: 633.2.03:631.5

A comprehensive approach to the technology of accelerated recovery of long-term grass stands in the hayfi elds and pastures for beef cattle and sheep is suggested on the basis of the low-cost methods of soil tillage and selecting adaptive kinds of grass mixtures.

Keywords: productivity, soil tillage method, grass mixtures, reseeding.

Belayeva T. N. The effect of fertilizers and growth regulator on the productivity of Echinacea purpurea in the south of the Tomsk region


УДК: 615.32:58

Echinacea purpurea is a promising forage crop containing the indispensable vitamins, microelements and the essential amino acids. Feed additives on its basis favorably affect the immunity of livestock. Th eeffect of growth regulator “Epin-Extra” and mineral fertilization on plant growth and development was studied on the samples which showed the highest green mass and dry matter yield in the conditions of the Tomsk region. The data may be used for development of the zonal cultivation of Echinacea. Both treatments had a positive eff ect on the productivity of purple conefl ower, the impact of “Epin-Extra” being more signifi cant than that of the mineral fertilization. Applying the growth regulator enhanced the accumulation of biologically active substances in the experimental Echinacea plants. Th e obtained data can be used for developing the crop’s cultivation technology for the taiga zone of West Siberia.

Keywords: Echinacea purpurea, “Epin-Extra”, mineral fertilizers, productivity.
