The research of influence of planting scheme and method of bushes forming on productivity and yield quality of Crystal grapes is advanced. The experiments are conducted under conditions of Low Pridonia in the industrial and intensive orchards created by re-forming of bushes.
Optimization of grapes feeding is the one of the effective elements of the technology, keeping and raising the soils fertility, plantings efficiency and resistance to adverse factors of the environment. Efficiency of plants mineral feeding increases with introduction of scientifically reasonable norms of fertilizers. The work purpose studying of soil and agribiological factors of effective fertilizers use on vineyards of Krasnodar Region. As objects of researches, the technical and universal grades of grapes are taken. Accounts and observations were made on agribiological and agrichemical indicators. As a result of researches the reaction of the main standard grapes varieties to change of foods conditions in dependence on the level of their productivity is established. The scientific basis of fertilizers use at a vineyards landing on the soils of different fertility and a water content are developed. The regularities of change of grapes quality and products of its processing in dependence on fertilizers, ways of the maintenance of soils and norms of bushes loading by a crop are revealed. The settlement method of determination of a grapes crops quality and efficiency of fertilizers depending on temperature conditions during blossoming is offered. Data of the forecast are used when the measures of quality management of raw materials in the adverse years are developing.
The fertilizers significant by effect the vital functions, harvest and grapes quality. Microfertilizers and growth regulators influence the growth of shoots, laying of fruit organs, leaves mass of bushes and a harvest of grapes. These indicators allow to predict the orchards productivity. The purpose of research is to reveal the influence of the different modes of mineral nutrition with use of PoliMiks-Agro preparation the growth processes of Moldova table grapes, the laying and differentiation of embryonic inflorescences, resistance of plants to a drought, productivity and quality of berries juice in the conditions of Anapa-Taman zone of wine growing. The PoliMiks-Agro fertilizer has applicated before blossoming and during active growth of berries and in two weeks before maturing of grapes. It is established that fertilizers have positively affected the shoot's productivity, the fruitfulness of bushes of Moldova grapes increased for 3-15 % The ratio of the connected and free water in the plant tissues is an indicator of plant resistance to dehydration, and consequently, also its adaptability under the water stress conditions. The biggest ratio of the connected and free water in the leaves the option with triple processing of grapes plants is characterized. The reliable changes of orchards productivity under the influence of PoliMiks-Agro are established. In comparison with control the harvest increase from fertilizers effect has made 2,4-3,8 t/hectare. The harvest increase is maximum when fertilizers are using in the norm of 2 liter/hectare. The research has shown that under the influence of microfertilizers the sugar content in the berries juice have increased and acidity of juice have decreased. The best indicators of sugar content of Moldova grapes were when processing of PoliMiks-Agro fertilizer in three time, on 1 liter/hectare.
The fertilizers have a significant impact on the activization of the over ground part of the plant, harvest and grapes quality. Micro fertilizers and growth regulators have influence on the growth of shoots, the laying of fruit formations in the overwintering buds and the leaf formation of bushes. These indicators are interrelated and allow to predict the productivity of plantings. The purpose of the research is to reveal the regularities of changes in the growth processes, the productivity and the quality of products under the influence of the different modes of mineral nutrition. The research are carried out in the agric ecological viticulture zone of the Black Sea of Krasnodar Region for Riesling technical varieties. Methodology of carried out scientific work included the placing of field one factor's experience with various options for application of "Polimiks-agro" fertilizer. The positive influence of not-root nutrition of fertilizer "Polimiks-agro" on growth processes, productivity, and quality of the Riesling grapes is established. In the field experience the number of shoots and one-year shoots growth and number of inflorescences are increased, the quality of grapes bunches is improved. On the treated bushes the color of leaves is intensive green, the lack of nutrients was not observed. It is shown the improvement of quality of the berries juice. Sugar content in the experience options is higher than in a control on 3.1-5.3 g/100 cm3 with decreasing acidity on 0.4-1.0 g/dm3. The reliable yield change under the influence of the "PoliMiks-agro" is established. The use of fertilizer has increased the productivity of Riesling grapes in all options of experience. The most outstanding options were released with the triple application of "PoliMiks-agro" in a dose of 2 l/hectare and with the use of "PoliMiks-agro" according to the sheme of 2: 1: 2 l/ hectare. The grapes harvest increases in these options of experiment on 4.0 and 3.1 t/ha or 36.4% and 28.2%, respectively.
The reaction norm of the introduced wine grape variety Merlot in unstable conditions of the moderately continental climate of the south of Russia has been established. The research was carried out in the agroecological conditions of the Black Sea viticulture zone of the Krasnodar region in the industrial vineyards of the GC Abrau-Durso using modern methods of field research. Agrobiological accountings were carried out using the methods of agrotechnical study of grapes. The climate at the research areais moderate continental. The average annual air temperature is 14.1 ºC, during the growing season (May September) is 22.2 ºC, the maximum rises to plus 37.0 ºC, the minimum during the wintering period of grapes falls to minus 19 ºC. The annual amount of atmospheric precipitation is 544 mm, during the growing season 208 mm, during the active growth of grape berries (II. June-III. august) 96 mm. The grape plant reacts with the modification variability of phenotypic traits to the variation of environmental conditions. The lower limit of the modification variability of the cluster mass is 98 g and the upper limit is 121 g., the grape yield is 3.3 kg/bush and 6.8 kg/bush, the sugar content of the grape berries juice is 20.1 g/100 cm3 and 21.6 g/100 cm3 . The reaction norm is 23 g, 3.5 kg/bush and 1.5 g/100 cm3 , respectively. Against the background of the application of fertilizers, the lower and upper limits of the modification variability increased respectively: the cluster mass by 16 % and 9 %, the grape yield by 48 % and 16 %, the sugar content of the grape juice of by 10 % and 7 %. The reaction norm decreased: reduction for the cluster mass as phenotypic trait was 22 %, for the grape yield 14 %, and for the sugar content of the berry juice 67 %.
