The article discusses the results of the research on winter soft wheat which is connected with the studies of yield variability, depending on the year conditions and the variety, conducted in 2003-2014. The objects of the research were 34 varieties included in different years into the State register of breeding achievements and recommended for cultivation. The experiment was carried out by the predecessor of soybean on the medium background of soil fertility. The varieties were being cultivated both with the protection against fungal diseases and without it. The method of dispersive and variance analysis was used in mathematical processing of the yield data. The parameters of ecological plasticity (bi) and yield stability (S2) have been calculated according to the methodology of E.A. Eberhardt and U. A. Russell (1984). The range of variability has been defined according to V.A. Zykin (2000), the fulfillment of the yield potential has been set according to E. D. Nettevitch (2001). The research revealed that the new winter soft wheat varieties included into the State register of breeding achievements are mostly productive and adaptive. Their yield increases mainly due to the upper threshold. The new varieties differ in yield stability but we have not found out a certain pattern. In conclusion it must be mentioned that the implementation of Eberhardt and Russell model in analyzing yield data allows us to estimate general tendencies in its variation when the conditions of the environment change and to identify the most valuable genotypes. In order to rank genotypes according to the characteristics which are being studied we have to choose an agricultural background on which their maximum potential is realized
The article represents the results of studying the spatial-dynamic factors and revealing the regularities of the global spread of Lumpy skin disease in cattle. The developed risk analysis and epizootological forecast provides the keeping up with a multi-year trend for the growth of epizootic tension in this disease for the period up to 2030. The highest probability of disease registration from 0.6 to 1.0 is predicted for the tropical agroecosystems of the African continent (enzootic zone) in 2018-2030. There is a real risk of disease in neighboring countries of Eurasia with the probability is less than 0.4. In the Russian Federation, outbreaks can occur in all federal districts of the country, but the highest probability of its occurrence is possible in agroecosystems of the subtropics of the North Caucasus and Southern Federal Districts of the country
In the article, on a small numerical example, we consider the similarity and difference of symptoms and syndromes according to their diagnostic meaning, i.e. according to the information they contain about the belonging of conditionals of animals to different nosological images. This problem can be solved for veterinary with the use of a new method of agglomerative cognitive clustering, implemented in Automated System-Cognitive analysis (ASC-analysis). This method of clustering differs from the known traditional methods in: a) in this method, the parameters of the generalized image of the cluster are calculated not as averages from the original objects (symptoms) or their center of gravity, but are determined using the same basic cognitive operation of ASC-analysis, which is used to form generalized images of the classes based on examples of objects and which really correctly provides a generalization; b) the similarity criterion is not the Euclidean distance or its variants, but the integral criterion of non-metric nature: "the total amount of information", the application of which is theoretically correct and gives good results in unortonormated spaces, which are usually found in practice; c) cluster analysis is carried out not on the basis of initial variables, frequency matrices or matrix of similarity (differences), depending on the units of measurement on the axes (measurement scales), but in cognitive space, in which one unit of measurement is used for all axes: the amount of information, and therefore the results of clustering do not depend on the initial units of measurement of features of objects. All this allows us to get the results of clustering, understandable to specialists and amenable to meaningful interpretation, well-consistent with the experts ' assessments, their experience and intuitive expectations, which is often a problem for classical clustering methods
We have presented methods of designing technologies of winter wheat harvesting by stripping with pile dividing stationary with optimization of harvesting–transport complexes in various conditions

The content of oil in the grain is given to both hybrids and their parent lines
The article presents experimental data of comparing anatomical and morphological features and properties of two peppermint varieties in the Hyaginsky district of the Adygea Republic. The economic importance of peppermint is very high. The essential oil rich in menthol, obtained from the leaves and mint colors, is widely used in the medical, perfumery, cosmetic and food industries. In this regard, of great value are varieties of a complex purpose - with high leaf productivity and high % essential oil and menthol.
Comparative analysis of morphological and anatomical features of peppermint raw material of peppery two varieties harvested in the territory of the Farm Sazonenko NV of Giaginsky district of the Adygea Republic, showed that the external features of plants differ from each other. The Kubanskaya 6 variety leaves have a larger size, with a higher content of essential oils, incl. menthol. In this regard, the yield of this variety was higher than that of Prilukskaya 6, and therefore the economic indicators of cultivation of the Kubanskaya 6 variety were the best
Fungal and bacterial diseases are the main cause of losses of beetroot during storage. Resistance to them should be regarded as an important economic value of this culture. Analyzing biennial data on the preservation and damageability of diseases during the storage of 18 samples of varieties and hybrids of beetroot grown in the Moscow region, samples were identified that have complex resistance to phomosis, gray and root rot, the most harmful diseases noted during the storage of beetroot. These are varieties Bordo 237, Bordovaya VNIIO, Dvusemyannaya TSHA, and Pablo F1 hybrid, which provide a yield of merchandise products of at least 80% and are characterized by a minimal degree of damage to the above-mentioned diseases. The above varieties and hybrids can be recommended for introduction into industrial vegetable growing and use in further breeding work as donors of resistance to diseases
Intensive viticulture as a sub-branch of the grape-wine industry of agriculture is developing due to the introduction of modern scientific developments. The intensification of production consists of laying vineyards with planting material of higher biological categories, highly productive clones of traditional and long-established selection varieties; advanced agrotechnological techniques and mechanized operations, etc. For import substitution of table grapevine in our country, it is especially important to introduce new big-berry varieties from early to late maturity, providing a continuous 100-day conveyor for harvesting, with a bunch of grapes, various colors and the shape of berries. In many countries of the world with developed viticulture, breeding programs are being conducted to create competitive table varieties. As a result, there were obtained Muscat of Italy (Italy), Cardinal, Red Globe (USA), Moldova (Moldova), widely spread all over the world. But the world market does not stand still and breeders are working on new varieties. In recent years, there has been a trend of enlargement of berries from 8 to 24 grams, preference is given to varieties with pink and red berries. So, for example, created in Ukraine - a very early variety of Livia; in Russia - the variety clones of Livia K and Rochefort K, the early varieties of the Memory of the Teacher, the Gift of the Nesvetay, the Preobraghenie and the Jubilee of Novocherkassk, and others. These varieties are bred according to the developed model, which shows the genetic regularities of the formation of maximum expression in transgressive recombinants in quantitative (mass of berries and bunches) and qualitative (shape and color of berries) traits associated with maturation
The results of laboratory experiments on the effect of different concentrations of SkQ3 (10- (6'- methylplastoquinonyl) decyltriphenylphosphonium) on the rate of growth of spring barley seedlings of varieties Sokol and winter wheat varieties Kalym in normal and under inadequate moisture conditions, as well as data from field experiments on the effect of pre-sowing processing SkQ3 on the morphometric indices of spring barley varieties Shhedry, hard winter wheat of the Lazurite variety and soft winter wheat of the Lydia variety are presented. As a result of laboratory experiments, an increase in the growth rate of 14-day-old seedlings grown in solutions of polyethylene glycol was shown when treating the seeds with 2.5 nM and 25 nM with SkQ3 solutions.
In the field experiments on the pre-sowing treatment of SkQ3 seeds, an increase in the morphometric indices of spring barley varieties of generic Lydia soft winter wheat and hard Lazurite winter wheat has been established, as well as an increase in the yield of winter wheat of both varieties as compared to the control
The results of the researches on studying of grape plantings processing influence of technical grade Viorika on its agrobiological and technological indicators are stated in the article. Experiences have been conducted in public joint-stock company "Pobeda" in Temrjuksky area in Krasnodar territory. The experience scheme included three variants in 2015: without processings (control); Farmaiodne - 0,04 %; Farmaiodne - 0,06 %; in 2016 - five variants: without processings (control); Farmaiodne - 0,04 %; Farmaiodne - 0,05 %; Farmaiodne - 0,06 %; Farmaiodne - 0,08 %. Processing of experimented plants included autumn and spring bushes washing in resting period (November-April) and spraying during the vegetation period. In 2015 spraying were conducted three times: before flowering, in a growth phase of berries, in the beginning of berries maturing phase; in 2016 the fourth spraying was added after the flowering. It is noticed, that application of Farmaiodne promotes more intensive accumulation of sugars in berries juice, acceleration of crop maturing, improvement of winematerials quality. The increasing of sprouts fruitfulness and increasing in average weight of a bunch is observed, that finally leads to authentic crop increasing in a bush and productivity. Application of Farmaiodne also has positive impact on growing processes, promoting increase in sprouts length and sometimes on thickness. According to the mixture of agrobiological and technological indicators the best results are received at the application in concentration of 0,05 % and 0,06%
