The article reviews the results of the studies of the influence of treatment of Saperavi vines with lignohumate of "A" grade on the quality of grape must and wine in Anapо-Taman zone of the Krasnodar region
The article reviews the results of the study of the influence of treatment of Saperavi grapes with the growth regulators (Biodux and Avibif) on the quality of grape must and wine in the Anapо-Taman zone of the Krasnodar region
The article presents the results of studies on the influence of the conditions of the foothill horticultural zone of the Krasnodar region and the crown shape on the agrobiological characteristics of the growth and fruiting of apple trees of the Idared and Renet Simirenko varieties. The objects of the study are Idared and Rennet Simirenko, trees of winter apple varieties, grafted on MM 106 rootstock. Trees were planted according to the 5 × 3 m scheme; crown width 2.0 ... 2.5 m. Orientation of rows from east to west. The garden is located on the northern slope with a slope of 3 degrees. The scheme of experience: option 1 - sparse-tiered crown (control); option 2 - flattened crown. In the experiment there were 2 options, in each option 10 typical trees were taken. Repetition: tree - plot. The location of the experiment is the Abinsky district of the Krasnodar region. Agricultural records of growth and fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was performed by the method of variance analysis described by B. Dospekhov. The results of our studies showed that when flattening crowns, the variety Idared increases the average weight of apples by 22.9%, the yield of fruits of the highest and first grade by 43.6%, the intensity of integumentary coloring of fruits in the peripheral zones increases by 1.44, and in the center crowns 2.7 times, compared with sparse-tier crowns. In the variety Renet Simirenko, the fruit weight increases by 8.9%, the yield of the highest and first grade fruits by 14.6%, the number of fruits with color by 18.7%. Thus, in apple orchards with a 7 x 4 m planting pattern (on MM106 stock) under the conditions of the foothill horticultural zone of the Krasnodar region, flattened tree crowns should be formed for the Aydared variety (aged 14-15 years), which significantly improves the quality of the products
There was given a review of the results of the study in
the conditions of sufficient moisture of Central
Ciscaucasia, the influence of planting terms and
presowing seed treatment by the drug called "TMTDplus",
containing Krezatsin growth stimulator in its
composition, on the development of corn hybrids of
different maturity groups of the selection of Krasnodar
Research Institute of Agriculture named after P.P.
Lukyanenko (Ross 199, Ross 299, Krasnodar 382 and
Krasnodar 410) and the All-Russian Research Institute
of Corn (Mashuk 170, Newton, RIC 345 and Eric), as
well as middle- maturity population Rossiyskaya 1.
The studies were conducted in accordance with the
thematic plan of scientific researches of the chair of
crop and forage production of the Stavropol State
Agrarian University. The soil surface of the
experimental station of StavrGAU was presented as
leached black soil. The technology of growing of
maize on the experimental plot corresponds to the
standard one for the present area and cultivar. The
predecessor is winter wheat. Sowing was performed in
three terms. The first (early) sowing term was carried
out at t = + 7 ... +8 ° C. The second (recommended) -
when t = + 10 ... + 12 ° C. The third (later) sowing
time was carried out at t = +15 ° C. The plant density:
early-maturing hybrids – 70 thousand pieces/ha, is
mid-maturing ones – 60 thousand pieces/ha, middleripe
– 50 thousand piece/ha, middle-later ones – 45
thousand pieces/ha. The scheme is single-row, with
spacing of 70 cm. The application of the studied drug
TMTD-plus helped to reduce the growing season of
maize plants for one - four days. Thus, changing the
sowing terms of maize hybrids and populations, we
can largely control the development of plants changing
the length of the growing season to two weeks and
form a harvesting conveyor, thereby reducing the
intensity of field work
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)
The article reviews the results of studying the adaptive potential of hybrids of corn maturity of different groups in the Central Caucasus. It discusses the variation of adaptive traits of maize hybrids (ecological plasticity and stability of the manifestations of agronomic traits), as well as stabilizing the yield of corn on an annual basis in the processing of seed preparation "TMTD-plus", which contains in its composition Krezatsin growth regulator
There were reviewed the results of the study of the
dependence of main phenological phases of
development of corn hybrids of different maturity
groups of the selection of Krasnodar Research Institute
of Agriculture named after P.P. Lukyanenko in the arid
zone of Central Ciscaucasia (Ross 199, Ross 299,
Krasnodar 382 and Krasnodar 410) and the AllRussian
Research Institute of Corn (Mashuk 170,
Newton, RIC 345 and Eric), as well as early-middle
Rossiyskaya 1 from the changes of average daily air
temperature of planting dates and preplant seed
treatment by the preparation "TMTD-plus", containing
the growth promoter called Krezatsin in its
composition. The studies were conducted in
accordance with the thematic plan of scientific
researches of the department of crop and forage
production of Stavropol State Agrarian University. The
technology of maize growing on the experimental plot
corresponds to the standard technology for this area
and culture. The sowing was performed in three stages.
The first (early) sowing period was at t = + 7 ... +8 °
C. The second (recommended) – was at t = + 10 ... +
12 ° C. The third (later) sowing period was at t = +15 °
C. There was identified a high inverse correlation
between the average daily air temperature and the
duration of the intraphase periods of maize
propagation. Thus, at the shifting of maize sowing
dates with the second half of May on the second half of
April we have optimization of heat regime in the
generative period and rising of the efficiency of use of
thermal resources of the region. There was marked the
acceleration of development of corn seedlings when
the average daily air temperatures was up to 12 ° C at
the samples with the application of the disinfectant
TMTD-plus
