Newest aromatic white berry wine grape variety Agapi was breeded by hybridization at the Athens Institute of Viticulture (Likovrisi, Greece) by professors P.Zamanidi, L.Troshin and P.Radchevskiy in 2006 by crossing the Greek varieties Afiri white with central European variety Traminer pink. Strong growth of shoots (2,1-3,0 m). Level of ripening vines is very high: over the entire length except the top. Length of production period 146-155 days. Productivity is very high: 25-30 t / ha. Average weight of cluster 300 g. Characterized by a high resistance to cold, drought and increased resistance to fungal diseases compared to varieties of Vitis vinifera L. Flower is androgynous. Bunch is medium, conical, medium density. Berry is medium, short elliptical or spherical, greenish-yellow in color, with a thick waxy coating. Cuticle of medium thickness, dense, and durable. Pulp and juice are with pronounced varietal flavor, similar to the aroma of Traminer pink. The sugar content is very high, more than 24%. Clusters of Agapi variety regardless of autumn weather conditions persist for a long time in the bushes. Variety intended for the manufacturing dry white wines of excellent grade and high-quality sparkling wines, dessert and sweet wines; suitable for production of high quality fragrant juices
The analysis of productive qualities of descendants of bulls of various linear kind has been presented in this article
In the long-term stationary experiment since 1968, we have studied the influence of crop rotation on soil fertility and productivity. The modernization schemes of field rotations in the direction of alternation crop change were held 40 years later, by introducing a scheme of oilseeds (canola, soy). According to the research, the authors made conclusions about the efficiency of cultivation of oil crops in crop rotations in the region. The resulting materials can be used in the development of crop rotations schemes for forest-steppe of Western Siberia

The article presents the results of studies on the use of different amounts by weight of triticale grain in feeding of young geese raised for meat. In the first group the wheat grain was 50% replaced by triticale grain, and in the second group the wheat was completely replaced by triticale grain. As a result of the experiment it has been found that the replacement of wheat by triticale in complete feed for geese provides a high growth rate but at 50 % inclusion of triticale grain the live weight at the end of the experience was110.8 g or 3% higher, as compared with the second group. It should be noted that up to 49 days old geese receiving compound feed with the 100 % replacement by triticale grain had a higher body weight. Complete replacement by triticale grain favoured the increase of carcass yield by 2.2% and decrease of body fat by 68.7 g as compared with the first group. Muscle tissue of the goslings fed the complete feed with complete replacement for triticale grain was characterized by 1% lower caloriс content than the goslings of the second group. According to biochemical composition of blood, all designed rations ensured normal metabolism in the fattened geese. The inclusion of triticale grain into the complete feed for young geese reduced their costs in the second group by 2.9%. But as a result the higher profit by 18.75 % was in the first group, which contributed to increased profitability by 2.4%. It is recommended to use up to 50% of triticale grain instead of wheat as part of complete feed for young fattening meat geese
In this article we present the results of the evaluation of 20 red currant varieties from NCRRIHV collection. Evaluation of varieties for commercial quality and biochemical composition of berries are presented
The main criteria in assessing the adaptive capacity of Actinidia deliciosa (kiwi), cultivated in Russian subtropics were yield of the introduced cultivars, as well as ecological (stability and periodicity of fruiting) and biological indicators (resistance and periodicity of fruiting). The studied nature of the way Actinidia cultivars react to the constantly changing weather conditions during the period from 1998 to 2011 will help to optimize the placement of the crop in subtropical zone, and use natural resources for its unique climatic properties of Russian territory in a sustainable way
Under conditions of vegetation experiment at soil artificial chloride salinization the dynamics of accumulation and distribution of sodium, potassium and calcium in organs of rice plants (Oryza sativa L.) have been studied, as well as their correlation with tissue hydration in ontogenesis. The significant restriction of salinization ions transport and accumulation, particularly sodium, in the actively functioning upper leaves and panicles has been observed. Whereas the content of calcium and potassium in the experimental and control plants differed slightly
