Description
Professional apple gardening is bound to particular risks, of which is essential losses of a harvest because of diseases. An apple scab, the caused Venturia inaequalis (Cooke) G. Winter, brings the greatest loss. The main approach in monitoring of a scab of an apple-tree is creation of grades, steady against pathogen. In the present work we have carried out phytopathology testing of generations of the seedlings received from the free pollination of six forms of a crab of Malus orientalis from a collection MOS VIR (Maykop) characterized by a relative resistance to the apple scab in 2-3 classes of damage by long-term data. For infection we used inoculum, consisting both of natural population of a scab, and of strains of pathogen of various cultivars and geographical origin. When carrying out padding infection increase in force of an infectious background that can be bound to selection of the plants of biotypes of a fungus that are most adapted for genotypes was noted. It is recommended for precise elimination of unstable plants at selection at early stages of an ontogenesis to carry out more than one serial infection during the season. By results of the phytopathological testing, we highlighted three Malus orientalis forms from the six studied No. 17982, 17985 and 3080 the most perspective stability genes for an introgressiya in a cultural gene pool of an apple tree

DISTRIBUTION AND VARIABILITY OF MORPHOLOGICAL TRAITS OF CENTAUREA DAGHESTANICA (LIPSKY) CZER
DescriptionThe distribution and variability of features of the endemic of flora Eastern Caucasus Centaurea daghestanica (Lipsky) Czer. were given in this article. Eleven locations of the species are detected and three of them are new ones. C. daghestanica grows in the lower and middle mountain belts from 400 to 1250 m above sea level. In the lower belt, the species is found on clayey areas of the solonchak valley of Kar-Kar and the limestone slopes adjoining the valley, on average on shale screes and stony slopes. Three populations of the C. daghestanica we studied. Species composition on the investigated sites was determined, and a geobotanical description is carried out. Project coverage of C. daghestanica in the studied populations varies within 2–5%. By generative individuals of different ages were represented mainly populations. One generative shoot from 30 individuals in each population was taken to reveal the variability of the generative shoot structure, on which 13 traits were taken into account. The degree of variability of the morphological features of C. daghestanica shoot is different, the influence of the altitude level on them is not the same. The annual shoot of C. daghestanica has an average of 3-5 branches of the first order. Branches of all levels are located at the bottom of the shoot

NEW ADVENTIVE WEED PLANT AMMANNIA COCCINEA Rottb. IN THE RICE FIELDS OF THE KRASNODAR REGION
DescriptionRice fields all over the world are one of the places of invasion of adventive weed species. They can reduce the yield of the rice crop by 20-30%. The phytomonitoring studies in the rice systems of the Krasnodar region in 2017 have discovered a new species of Ammannia coccinea Rottb. (Lythraceae) among the weed vegetation of the grain crops. The article gives a botanical description of the species; its biological and ecological features and ways of its distribution are discussed. Ammannia coccinea is an annual plant, light-loving and hygrophilous. The country of origin is North America. This is one of the most malicious weeds in California and the United States in general. In Asian and European countries, the plant is brought with rice seeds. Currently, in many rice-growing regions of the world, the species A. coccinea tends to spread and increase the severity of infestation. The species was registered in the Krasnodar region in the rice fields of the Abinskiy, Kalininskiy, Krasnoarmeiskiy and Slavyanskiy regions. The number of plants of A. coccinea does not exceed one plant per 10 m2, with the exception of three locations of invasion, where the density is up to 5-7 pcs/m2 and the plants occupy an area about 0.5 hectares. Considering the fact that in rich soils the height of the plant reaches 1 m, with the ramification of the stem, the plants go to the first tier. They successfully compete with rice plants, suppressing their growth and development. This can adversely affect crop yield. The article discusses the reasons for the appearance of A. coccinea in the rice fields of the Krasnodar region

Description
Techniques of value analysis and "Direct-costing" are well-known and popular. The ideas and principles of value analysis and the method of "Direct costing" are very similar, if not identical. On the one hand, these ideas are very reasonable, well grounded theoretically and proved its effectiveness in practice. On the other hand, the wide use of these methods is hampered by the difficulty of obtaining large amounts of detailed technological and financial-economic information, as well as the need for careful research by competent professionals, well-versed in substantive subject area. This is the contradiction between the desire to apply the methods of the value analysis and "Direct costing" and difficulty to perform it in practice. This contradiction constitutes a real problem and may often be discouraging and frustrating. In this work, we propose a simple and effective solution to this problem, theoretically well-informed with all the necessary methodological and software tools and widely and successfully tested in practice. The proposed solution is based on two simple ideas: 1) instead of collecting and holding a meaningful large amount of technological and financial-economic information we might apply approaches, pleasant management theory; 2) to create systems for automated control of natural and financial-economic efficiency of expenses we might use the automated system-cognitive analysis and its software tool – an intellectual system called "Eidos". In the name of the specialty 08.00.05 – Economics and national economy management, there are such words: "management of enterprises, branches, complexes, innovation." The use of the term "Management" implies that there is a model that reflects the influence of factors on the object of control, and there is the management system making decisions based on this model. However, as a rule, the dissertations in this field have nothing of this, except only financial and economic calculations. The article proposes an approach based on the control theory, removing this disadvantage

IMPROVING THE CLEANING PROCESS OF SEEDS MATERIAL ON AIR-SIEVE GRAIN CLEANING MACHINES
DescriptionThe article presents the theoretical and experimental research of the guide wire, made of polytetrafluorethylene, for sieve system of air grain cleaning machines. We have calculated trajectory of movements of the components of piles of sunflower seeds in the vertical pneumatic channel when they are vanishing from the surface of the guide wire at its various parameters. Specifying the location of a guide wire polytetrafluorethylene in air-sieve grain cleaning machine was carried out in an experimental setup. The guide wire of polytetrafluorethylene was installed in three locations: 1) at a distance of 20 mm to the pneumatic channel; 2) on the levels with the pneumatic channel; 3) at a distance of 20 mm inside pneumatic channel. The approach of the guide wire into the inside of the pneumatic channel in the experimental setup the quality of sunflower seeds increased with 97.61 to of 99.08 %. The content of organic impurities, milled and broken seeds in the pile decreased respectively from 1.83 to 0.21 %, to 1.29 0.66 % 0.51% to 0.25% in the manufacture of wire made of polytetrafluorethylene. To increase the purity of the seeds of the main culture we use a photoelectron separator, and the received seeds for animal feed were in the form of sunflower cake produced on screw presses. As a result of carried out experimental and theoretical researches it is established, that the guide wire shall be made of polytetrafluorethylene and are placed inside the pneumatic channel at a distance of 20 mm and an angle of 40°, which allows to improve the quality of the seeds material and increase the speed of their input to pneumatic channel air-sieve grain cleaning machines type MVU-1500
