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 187
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

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 179
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)
