DescriptionNutrient media for shoot development from shoot tips 0.5-0.8 mm with several leaf primordia in four grapevine genotypes were optimized by means of a mathematical design of experiment. Over the range of component concentrations CaCl2 had considerable the highest effect on shoot tip development compared to other components of the media. Grapevine genotypes were different in their needs for concentrations of macro-elements to optimize the process of their growth and development. Shoot development from shoot tips in each grapevine genotype as a function of macro-element concentrations in media must be described by an individual regression equation. The proposed method of result evaluation and the mathematical design of experiment may be used in physiological and agricultural research for optimization of processes affected by numerous factors. The optimized media for shoot tip development may by used for sanitation of grape plants from viruses in meristem cultures

DescriptionTwo methods were developed, one to assess experimental results by reducing a number of developmental parameters to the overall quality, leading to the overall quality criterion, and the other to optimize processes affected by numerous interacting factors, in-vitro plant development in this case, by applying a mathematical design of experiment. Single-bud cuttings with one leaf of two Vitis vinifera L. genotypes were excised from the central part of two-month-old in-vitro grown plants and used as explants. The explants were established on bridges of filtering paper in liquid media and on solid media. Eighteen modifications of these media contained five macro-elements, each at three concentrations, and the distribution of these macro-element concentrations followed the law of random numbers (Experiment I). Parameters characterizing arm, leaf and root development of two-month-old plants of each study genotype established on each liquid or solid medium were reduced to the overall quality of plant development. Since the study genotypes differed in the ability to grow on liquid and solid media with different macro-element concentrations and also in the ability to utilize these macro-elements, the dependence of in-vitro plant development on macro-element concentrations was described by different regression equations. That is why the regression equation describing the average outcome of plant development in the two genotypes on liquid and solid media was not as significant and the description of the process was not as adequate (determined) as regression equations calculated for each process. The regression equation which describes the dependence of the average outcome of plant development on macro-element concentrations in Experiment I is as follows: y5 = 0.027 + 0.116x22 + 0.109x2x4 + 0.106x2x3 + 0.114x4. Stepwise calculation of macro-element concentrations to optimize in-vitro plant development was done based on macro-element concentrations of the initial medium of Experiment I as starting points since that medium was best efficient for this purpose by using regression equation (y5) and algorithms of multiple curvilinear stepwise regression according to the Box-Wilson method of steepest ascent. Experiment II was undertaken where macro-element concentrations (‘steps’) were calculated in a stepwise manner to optimize in-vitro plant development of the two V. vinifera genotypes and the rootstock ‘Kober 5BB’. This led to a liquid medium and a solid one which enabled a better plant development in the three genotypes relative to the use of controls: media with ½ MS macro-elements and the initial medium whose macro-element concentrations entered as starting points to calculate ‘steps’ for optimization of in-vitro plant development. The optimized medium contained macro-elements: 318 mg l-1 NH4NO3 (x1), 1188 mg l-1 KNO3 (x2), 370 mg l-1 MgSO4 7H20 (x3) (MS), 370 mg l-1 KH2PO4 (x4), 331 mg l-1 CaCl2 (x5) (MS), and other substances at optimum concentrations adjusted earlier: ¼ MS Fe-EDTA, ¼ MS micro-elements, 20 mg l-1 myo-inositol, 0.1 mg l-1 thiamine (MS), 0.5 mg l-1 nicotinic acid (MS), 0.2 mg l-1 pyridoxine, 2 mg l-1 glycine (MS), 0.1 mg l-1 indole-3-acetic acid, 10 g l-1 sucrose and, only for solid media, 7 g l-1 Difco agar. The optimized medium may be used for propagation of virus-free plants, valuable clones and grapevine genotypes created by gene engineering. The mathematical design of experiment reported in this paper which enables stepwise optimization of in-vitro plant development may be used both in agriculture and in the food industry

Description
The care of the finance is the starting moment and a final result of the activity of any subject of managing. The organization with a reliable financial condition is a part of the locomotive, which accelerates market transformations, improving a national economy. In the article, we showed the analysis of theoretical and conceptual positions of financial stability of the organizations. It is revealed, that their accounting reporting used for an estimation of a financial condition, the beginnings and the terminations of the accounting period are made only for a moment, and creation of the income of the organization and its further distribution completely drop out of a field of vision. The article has a research character, expressed that in it the basic approaches to an estimation of financial stability of the organization on an example of Society with limited liability «Gumilovskoe» are considered and is revealed, that by different techniques the type of financial stability from unstable up to normal is inherent in it. With the purpose of improvement of financial stability of Society with limited liability «Gumilovskoe» optimization of its balance by a correcting of some articles of accounting balance based on recommended values of financial parameters according to the multifactorial model offered by A.V. Grachev is made. Economic feasibility of the given optimization is proved and the complex of actions on increase of financial stability of the organization is offered

Description
The significance of humus content in soils of the Krasnodar region is decreased. Losses amount is 0,03- 0,05 % every year. The main means of preservation of soil fertility is the introduction of such organic fertilizers as manure. The availability of manure’s use has decreased significantly in connection with the reduction of livestock in agricultural organizations of the Krasnodar region. It causes the necessity of searching of other ways of replenishing of soil fertility. The challenge is to ensure a positive balance of organic matter in soil without application of manure. The reproduction of the soil fertility can be achieved at the expense of proper selection of agricultural cultivars in the crop rotation and provision of optimal structure of sown areas. The modeling of the structure of sown areas using the developed economic-mathematical model allows to determine the optimal composition and the areas of crops for maximum gross or net income with a positive balance of humus. It is proposed to use the general indicators of economic evaluation - gross or net income, increased (decreased) in the value added of (left) humus to assess the effectiveness of land use. The calculations were made on the example of the Ltd Company “Vorontsovskoe” of Dinskoy District, they may be adopted for any agricultural organization

OPTIMIZATION OF GRAPE GROWING TECHNOLOGY BASED ON USING THE METHOD OF YIELD PROGNOSIS
06.00.00 Agricultural sciences
DescriptionThe article highlights the questions of preliminary determination of the yield of vineyards, grape harvest prediction method to determine the optimal length of fruit cutting of shoots and load bushes wintering eyes, kidneys examined productivity index wintering buds (CP), which shows how many inflorescences have an average for each left eye escape when cutting to length, including the dead. It was found that the yield of grapes has a great influence the degree of differentiation of inflorescence of rudiments in the central buds overwintering buds. From the moment of laying the harvest of grapes in hibernating little eyes in the form of embryonic inflorescences until commercial harvest takes two growing seasons. During this period the generative organs of grape plants are affected by many factors of the environment. Heterogeneity was found of buds along the length of one-year matured shoots. It is expressed in the fact that many grape varieties fruitfulness buds at the base of the shoot are much lower compared with upstream eyes. A certain death of wintering buds (primarily, the main kidney) at the end of the growing season, before the autumn frosts. The main reason for the death of buds during the growing season - from defeat fungal diseases. Taking into account the percentage of deaths of buds proposed a new exponent forming embryonic kidney main inflorescence - productivity index of buds by the ratio of embryonic stems to the number of buds, including the dead. Thus, annual forecasting of grape harvest next year to cutting the bushes by the proposed method makes it possible to scientifically establish the optimal cut length of shoots and fruit load on the bush eyes. This helps to realize directly the potential of each variety and vineyard site and get maximum yields even in years with low fruit tab formations

EXPERIENCE OF USING NATURAL MINERAL COMPOUNDS FOR METABOLIC DISORDERS IN CATTLE
DescriptionIn this study we show the results of the use of natural mineral compounds in metabolic disorders in cattle-breeding complexes of industrial type. According to official data for 2013-2015, based on the biochemical analysis of blood of cattle, that was held in some farms of Samara region, significant metabolic disorders were determined due to decrease in total protein level on 31,5% in average, decrease in alkali reserve – on 26,9% of samples, decrease in calcium concentration – on 40,7%, decrease of the phosphorus – on 8,1%, decrease in carotene – on 81,7% and glucose – on 84,3% of studies. Clinical examination of herd revealed a high level of animals with obvious signs of mineral metabolism disorders (osteodystrophy and rickets of alimentary origin) and comorbidity (nutritional anemia, gastroenteritis, pneumonia, disturbance of protein, carbohydrate and vitamin metabolism, and others). The use of complex natural compounds improves the efficiency of the traditional complex of treatment and prophylaxis, causing an increase in the total concentration of calcium in the blood serum on 10-55%, increase in calcium-phosphorus ratio till 1,27-2,3, increase in annual growth rate of young animals’ body weight on 8,2-44,8%, increase in milk production on 5,9-16,3%. Preparations have an antianemic action, normalize indicators of micronutrient metabolism of proteins and carbohydrates, enhance non-specific resistance factors and prevent the development of non-contagious internal pathology
