Article is devoted quality, production and use of prewilted silage as a best kind of ensilage forage. In a review the forage names are considered. According to the theory of operationalism in 60s years of last century there was introduced a term “haylage”, and in 2010 and 2014 in Belarus (СТБ 1223), and then in the Russian Federation (ГОСТ Р 55986) the term “prewilted silage”. In Germany the prewilted silage (“Spitzensilage”, “Topsilage”) is considerd as a main kind of forage for cows, yielding 10000 L milk pro year. Now the annual volume of prewilted silage production in the Russian Federation exceeds 10 million tons. In some books published last years the information on a chemical composition and nutritive value of prewilted silage produced in the Vologda region and Udmurtiya Republic is reported. Mainly the article is devoted analysis of these data, examples of different quality prewilted silage are given, progressive methods for preparation of a highly nourishing forage are recommended. Foreign and domestic prices on fodder analyses are pointed out. It is recommended to improve system of a forage quality evaluation and use in an animal feeding formula.

Recently, more and more people are paying attention to healthy lifestyle, including nutrition, giving preference to natural products. One of these products is honey. The chemical composition of honey is represented by a large number of nutrients: easily digestible carbohydrates, amino acids, enzymes, minerals, vitamins, organic acids, causing its nutritional, dietary¬, and medicinal properties. In the article, the authors analyzed the state of honey production in the country, reflected the share of imports in the market and the share of exports in production, the main factors affecting the honey market are investigated. Based on the results of studies of honey from different regions of the Russian Federation and the requirements of international legislation on product safety, the authors have developed proposals to improve the competitiveness of hive products, both in domestic and foreign markets.

Most of the Russian Federation zones has a continental climate and significant amplitude of temperature fluctuations in the autumn-winter and spring periods are one of the most urgent problems of wintering the grape plants. The conducted researches showed that among the introduced varieties of grapes, studied in the conditions of the Omsk region, the two groups of varieties with a degree of freezing of eyes are distinguished in the average for 2012-. 2016 years at the level of the control grade Katyr (26.3%) - Ayar -27.3, Tukay - 31.5%; the freezing is higher than the control grade level in the following varieties: GF -2-7-2 - 42.2, Agat Donskoy - 47.6, Edna 48.1, Moscovityanin -53.3%. The prospects for growing grapes in trench culture in the Omsk region are varieties with a relatively stable and potentially high productivity, such as Tukay, Edna, an average of 5.2 and 5.0, a maximum of 8.8 and 11.4 kilogramm per bush, and Agat Donskoy and GF -2-7-2, an average of 4.9 and 4.7, a maximum of 12.4 and 10.1 kilogramm per bush. The results of overwintering of grapes in trench culture largely depend on the presence and height of the snow cover, it is recommended to use additional insulation of trenches over the polyethylene coating with a layer of sawdust or humus in conditions of the Omsk region in the absence or a small snow cover.

The results of the work to create a complex of high-precision hardware for the unit of length reproduction and transferring carried out at “D. I. Mendeleyev Institute for Metrology (VNIIM)” are represented. This complex will serve as the basis for the further development of the reference base of the Russian Federation in the field of length measurements and will allow reproduction of the unit of length at two wavelengths of 633 nm and 532 nm, as well as measurements of the wavelength of laser sources in vacuum in the range from 500 to 1050 nm.
