THE QUALITY OF MERLOT GRAPE AND WINE ON A BACKGROUND OF APPLICATION OF MINERAL FERTILIZERS IN THE CONDITIONS OF ANAPA-TAMAN AREA

abstract 1301706090 issue 130 pp. 1236 – 1248 30.06.2017 ru 360
The article reviews the results of studying the influence of mineral fertilizers on the qualitative indices of the Merlot grape variety in the Anapo-Taman zone of the Krasnodar region. The technology of cultivation of grapes on the experimental plot was in accordance with the accepted for the given zone and culture. Agrobiological work was carried out at the optimal time and had a high quality of execution. Grape bushes are laid in a 3.0 x 2.0 m pattern. Formation - a twoshoulder horizontal cordon. On the bushes we formed the same load of shoots and bunches. Scheme of the experiment: option 1 – no fertilizers (control); option 2-superphosphate with a mixture of potassium salt (P90K90) from the autumn; option 3 –nitroammofoska (N120P120K120) from autumn; option 4 – ammonium nitrate (N60) in early spring. Analysis of the results of studies on the study of biological features of growth, fruiting, yield and quality of Merlot grape varieties on the background of the use of mineral fertilizers shows their high efficiency in the conditions of the AnapoTamanskaya zone of the Krasnodar region and can be recommended for use in production conditions. Mineral fertilizers ensures the receipt of dry bulk wine of superior quality control sample (without fertilizers) the concentration of tartaric acid 17.3 25.1 percent, phenolic compounds 17.1 – 40.0 %, and alcohol content of 7.2 and 9.3 %, titratable acids 11.8 and 13.7 %, given extract by 17.4 %, with a decrease of the mass concentration of total sulfur dioxide and pH. The most effective is the introduction of NPK (N120P120K120)

INFLUENCE OF FERTILIZERS ON QUALITY OF CHARDONNAY GRAPES AND WINE MATERIALS

abstract 1471903014 issue 147 pp. 53 – 61 29.03.2019 ru 363
The article presents the results of the fertilizers use effect on dry wine materials produced from the Chardonnay variety, grown in the Anapo-Taman soil and climatic zone of the Krasnodar region, Russia. As a result of wine materials analysis, increase of tartaric acid was noted, with the autumn application of phosphorus-potassium fertilizers and the spring application of ammonium nitrate. At the same time, its optimum content was noted with nitroammophos. Also, the minimum concentration of malic acids was detected by the application of nitroammophos with potassium fertilizers. In its turn, early spring application of ammonium nitrate reduced the concentration of malic acid below the control sample (without fertilizers). It was revealed that the use of mineral fertilizers in this winemaking zone also contributed to a reduction of lactic acid in the must. At the same time, the application of nitroammophos (especially together with other mineral fertilizers), contributed to the accumulation of citric and succinic acids, as well as phenolic compounds. Moreover, the application of phosphate-potassium fertilizers in the autumn contributed to the accumulation, and, consequently, also to the increase in the content of phenolic compounds in the resulting must. In addition, the studied samples of wine materials contained high alcohol concentrations and low concentrations of sugars with volatile acids. At the same time, the maximum amount of alcohol exceeding its content in the control sample was revealed when phosphorus-potassium fertilizers were used together with nitroammophos fertilizers. It is also noted that the application of ammonium nitrate did not affect this indicator. As a result, the use of mineral fertilizers in the studied concentrations made it possible to prepare wine materials that contained a low concentration of sulfur dioxide, which is substantially lower than the harmful concentration for humans. In addition, increased concentrations of hydrogen ions in variants with the application of phosphate-potassium fertilizers have made it possible to reduce the number of iron tanates and the intensity of oxidation-reduction processes

INFLUENCE OF MINERAL FERTILIZERS ON PRODUCTIVITY OF MERLO TECHNICAL GRADE IN THE CONDITIONS OF ANAPA-TAMAN ZONE

abstract 1311707129 issue 131 pp. 1571 – 1586 29.09.2017 ru 390
The article reviews the results of studying the influence of mineral fertilizers on the uvological, yielding and qualitative indices of the Merlot grape variety in the Anapo-Taman zone of the Krasnodar region. The technology of cultivation of grapes on the experimental plot was performed in accordance with the accepted for the given zone and culture. Agrobiological work was carried out at the optimal time and had a high quality of execution. Grape bushes were laid in a 3.0 x 2.0 m pattern. Formation - a two-shoulder horizontal cordon. On the bushes, there was formed the same load shoots and bunches. Scheme of experience: option 1 – no fertilizers (control); option 2 - superphosphate with a mixture of potassium salt (P90K90) from the autumn; option 3 – nitroammofoska (N120P120K120) from autumn; option 4 – ammonium nitrate (N60) in early spring. Analysis of the results of the studies on the study of biological features of growth, fruiting, yield and quality of Merlot grape varieties on the background of the use of mineral fertilizers shows their high efficiency in the conditions of the Anapo-Tamanskaya zone of the Krasnodar region and can be recommended for use in production conditions. Autumn application of nitroammofoski (N120P120K120) provides an increase in yield by 68.3%, increases the yield of mash from a hectare by 76.7% and the collection of sugar by 97.6%. Autumn application of phosphate-potassium fertilizers (P90K90) and early spring application of ammonium nitrate (N60) also contributed to an increase in yields by 33.3 and 40.6%, respectively. On the output of the wort, these options are equal, and for the collection of sugar phosphate-potassium fertilizers exceed ammonia nitrate

AGROBIOLOGICAL EVALUATION OF NEW STRAWBERRY VARIETIES IN THE CONDITIONS OF THE PRIKUBANSKAYA ZONE OF GARDENING IN THE KRASNODAR REGION

abstract 1491905016 issue 149 pp. 81 – 91 31.05.2019 ru 451
The article presents the results of studies on the biological characteristics of growth and fruiting, as well as the yield of adaptive varieties of strawberries in the conditions of the Prikubanskaya horticulture zone of the Krasnodar region. The objects of study are new and promising varieties of strawberries: Zenga-zengana (k), Onda, San-Diaz. The experiments were performed using the method of randomized reps. In the experiment there are 3 options, in each there are three replications of 20 plants. Variants and repetitions are placed sequentially. Agricultural records of the growth and fruiting of strawberry plants were carried out according to generally accepted methods; statistical processing of research results was carried out using the analysis of a variance method described by B.A.Dospehov. The results of our research showed that Zenga-zengana bushes (control) turned out to be the tallest. In the Onda variety, the height of the bush is 2 cm less than in the control variety; and San Diez varieties are 4 cm, respectively. It should be noted that the most undersized plants require a smaller area of nutrition. It has been established that flowers pollinated a few days after their disclosure develop more rapidly into berries than those that were pollinated immediately after opening. Pollen in flowers of the first order is less than in flowers of the third or fourth order. The stamens of the first flowers are often underdeveloped, their pollen is released and germinates worse. In our experience, the average weight of fruits and the yield as a whole depends on the biological productivity of the varieties. Onda was the most fruitful variety, and the rest varieties were at the control level

INFLUENCE OF BASIC TREATMENT ON AGROPHYSICAL SOIL PROPERTIES IN CROPS OF WINTER BARLEY

abstract 1531909002 issue 153 pp. 8 – 18 29.11.2019 ru 536
The article presents the results of studies on the influence of the main tillage in the technology of cultivating winter barley on its agrophysical properties. The object of research was winter barley, sort Rubezh, the predecessor - winter wheat. Soil - heavy duty, low humus, typical leached chernozems. The studies were carried out in a stationary experiment on the basis of the experimental field of the Department of General and Irrigated Agriculture at KubSAU in accordance with generally accepted methods for experiments with grain crops. Scheme of experience (primary tillage): option 1 (A0) - dump plowing to a depth of 20-22 cm (control); option 2 (A1) - chisel for 20-22 cm; option 3 (A2) - disk peeling at 8-10 cm; option 4 (A3) - zero treatment (direct sowing). Based on the research, a general orientation is revealed in the technology of cultivating winter barley to reduce the agrophysical indicators of the soil throughout the growing season of the development of its plants while lowering the tension of its main processing. So, the density of the soil was minimal, and the structure and moisture of the soil, as well as the reserves of productive moisture were maximum on the option with dump plowing to a depth of 20-22 cm. Conducting deep loosening at the same depth (chiseling by 20-22 cm) somewhat worsened these parameters . Implementation of disk peeling in the main tillage (by 8-10 cm) contributed to the deterioration of these parameters. The option of zero tillage was in last place according to these indicators. And only before harvesting, zero tillage contributed to the formation of higher soil moisture and productive moisture reserves
