DEPENDENCE ON THE MECHANICAL COMPOSITION OF THE APPLICATION OF GROWTH SUBSTANCES TO THE GROWING VARIETIES OF GRAPES

ABSTRACT

In this article, the importance of the period of application of growing substances to grape varieties depends on their mechanical composition, the period of application of growing substances to grape varieties is used before flowering, 10 days after flowering, during the period of accumulation of water in the bunches and when the color of the bunch of grapes begins to enter. If one application of growth substances increased the yield by 5-25% compared to the control variant, two applications of growth substances increased the yield of grapes by 10-45%, and it was reported that the duration of application of growth substances depends on the mechanical composition of the grape head.

As a result of scientific research aimed at the development of viticulture, which is an important branch of world agriculture, the development of optimal standards for the use of the best growing substances to increase the yield and quality of grape varieties remains one of the current problems [1]. To find a solution to this scientific problem, scientists from various fields are conducting scientific research, including Viticulture and Enology Research Center (USA, California, W.M. Kliewer), Research Institute of Horticulture, Viticulture and Winemaking (Georgia, Howell. G.S), Instituto Nacional de Tecnología Agropecuaria (Argentina, Poni S, Casalini), Research Institute of Viticulture, Winemaking and Fruitcrops (Armenia, Chalak S.U., Kulkari S.S.) [2]. Many researchers who worked in Uzbekistan conducted scientific research on the dependence of the method of growing grapes on growing substances. D.I. Baulin, M.G. Tsetlin, A. Adylbekov, N. Buzin, V.I. Garboch, R.Yu. Soldatova, A. Mirzaev, G.I. Khaydarkulov, M.R. Musamukhammedov, K.S. Sultanov, J.N. Fayziev and O'.O. Ochildiev, A.M. Malikov, P.E. The Egamberdievs carried out various scientific researches on increasing the yield of grapes [3]. However, no studies have been conducted on the dependence of growing substances on the mechanical composition of the grape head in the cultivation of young varieties of grapes by the traditional method [4; 5].

The development and implementation of optimal standards for the influence of grape clusters on the quality and the dependence of physiological and biochemical processes on growing substances in the cultivation of ripe varieties remains an urgent task, and its solution will allow solving a number of problematic issues that allow obtaining a high and high-quality harvest from vineyards.

The subjects of the study were grapes of Kishmish chery, Kishmish belyy ovalnyy, Kishmish sogdiana, F1 Black raisin, F1 White raisin, and F1 Pink raisin varieties, as well as the standards of growing substances.

Research materials and method. The experiments were developed by Kh. Ch. Boriev, N. Sh. Enileev and others "Methodology of calculations and phenological observations in conducting experiments with fruit and berry-bearing plants" (2014), M. A. Lazarevskiy "Metody botanicheskogo opisania i agrobiologicheskogo izucheniya sortov vinograda" " (1946), "Izuchenie vinograda dlya opredelenia ego ispolzovaniya" (1963) by N.N. Prostoserdov, conducted according to the recommendations and methods presented in the methodical literature.

Statistical analysis of research results was calculated in Excel 2010 and Statistica 7.0 for Windows computer programs with a confidence interval of 0.95% according to the method shown by B.A. Dospekhov.

Analysis and results. The following were determined from the results of the research conducted in the experimental area. In the experiment, it was found that the method of growing grapes and growing substances have a high effect on the mechanical composition of grape bunches and the formation of bunches.

When the mechanical composition of the grape head cluster was studied during the cultivation of Kishmishbop grape varieties by the fairy method, the results obtained from Kishmishbop varieties differed significantly from each other according to the variants.

Studying the effect of growing substances on the mechanical composition of grape varieties. ,1 cm, the flesh and juice of the grape head 95.7%, the band of the grape head 3.7%, the pith of the grape cluster 0.4% and the rudimentary seed of the grape cluster 0.2%, the grower Hosilin extra 25 mg/l, Amber acid 50 mg/l, NPK 125 mg/l, Calcium 100 mg/l, Phytactive Plant 50 mg/l. (1) When applied 10 days after flowering, the weight of the grape head was 22.6 g heavier than the control variant, and the flesh and juice of the grape head was 0.2% higher. Grower Hosilin extra 25 mg/l, Bornaic acid 50 mg/l, Cytogummate 200 mg/l, Fitovak 100 mg/l, Magnesium 50 mg/l. 3 g weight and meat and juice yield was found to be 0.4% higher.

The Kishmish Sogdiana variety of grapes in the untreated (control) variant had a weight of 180.9 ± 3.2 g, the amount of flesh and juice of the grape head was 95.3%, the grower Hosilin extra 25 mg/l, succinic acid 50 mg/l l, NPK 125 mg/l, Calcium 100 mg/l, Phytactive Plant 50 mg/l. (1) When applied 10 days after flowering, the weight of the grape head is 14.8 g heavier than the control option, the output of the grape head and flesh is 0.4% higher, the grower Hosilin extra 25 mg/l, Bornaic acid 50 mg/l, Cytogummate 200 mg/l ,Phytovac 100 mg/l, Magnesium 50 mg/l, (2) When applied when the grapes start to color, the average weight of the grape head was 29.4 g and the amount of flesh and juice of the grape head was 0.7% higher than the control option.

In the F1 black raisin variety of grapes, the weight of the grape head was 308.2 ± 4.2 g, the flesh and juice of the grape cluster was 93.6% in the untreated (control) variant, compared to the control variant, the growing Hosilin extra 25 mg/l, succinic acid 50 mg /l, NPK 125 mg/l, Calcium 100 mg/l, Phytactive Plant 50 mg/l. (1) When applied 10 days after flowering, the weight of the grape head is 42.6 g heavy, the flesh and juice are 0.2 high, the grower Hosilin extra 25 mg/l, Bornaic acid 50 mg/l, Cytogummate 200 mg/l, Fitovak 100 mg /l, Magnesium 50 mg/l, (2) It was found that the weight of the grapes increased by 65.6% and the amount of flesh and juice of the grapes increased by 0.6%.

In the F1 white raisin variety of grapes, in the untreated (control) variant, the weight of the grape head was 240.4 ± 3.8 g, the flesh and juice of the grape cluster was 94.3%, compared to the control variant, the growing Hosilin extra 25 mg/l, succinic acid 50 mg /l, NPK 125 mg/l, Calcium 100 mg/l, Phytactive Plant 50 mg/l. (1) When applied 10 days after flowering, the weight of the grape head is 6.5 g heavy, the flesh and juice are 0.3 high, the grower Hosilin extra 25 mg/l, Bornaic acid 50 mg/l, Cytogummate 200 mg/l, Fitovak 100 mg /l, Magnesium 50 mg/l, (2) It was observed that the weight of the grape head was 14.9 g heavier and the amount of flesh and juice output of the grape cluster was 0.8% higher when it was applied when the color started to enter the composition of the bunches.

In the F1 Pink raisin variety of grapes, in the untreated (control) variant, the weight of the grape head was 226.7 ± 4.1 g, and the flesh and juice of the grape cluster was 94.1%. Compared to the control variant, the grower Hosilin extra 25 mg/l, succinic acid 50 mg/l, NPK 125 mg/l, calcium 100 mg/l, Fitaktiv Plant 50 mg/l.

It can be concluded from the results of the research that the period of application of growing substances to the growing varieties of grapes is highly dependent on the mechanical composition. In the untreated (control) variant, the weight of the grape head was 240.5 g, the Cultivator Hosilin extra 25 mg/l, Succinic acid 50 mg/l, NPK 125 mg/l, Calcium 100 mg/l, Fitaktiv Plant 50 mg/l l. (1) When applied 10 days after flowering, 5.0% compared to the control option, when the color of the buds begins to enter, the grower Hosilin extra 25 mg/l, Bornaic acid 50 mg/l, Cytogummate 200 mg/l, Fitovak 100 mg/l, Magnesium When using 50 mg/l substances, it was found to be 23.0% higher than the control option. It is recommended to double the amount of organic and mineral substances in grape-growing farms along with double application of growing substances.
