The article reviews the results of studies of adaptive properties of the hybrid corn of different groups of maturity at the background of anthropogenic factors. It discusses the practical application of research results in order to maximize grain yields from 1 ha, environmentally friendly products (including at cultivation of corn on the protected areas), economically viable crop with maximum return on investment, as well as the possibility of extensive corn cultivation technology with limited material resources-money producers
The article provides an overview of the results of the study of the growth and development of corn in the conditions of the northern zone of the Krasnodar region, depending on the density of plant standing and seed dressing. The object of research was an early-ripe hybrid of Ross 199 corn. Two factors were studied in the experiment: factor A - plant stand density (60, 70 and 80 thousand units / ha), factor B - seed dresser (Maxim XL (k) and Maxim Quatro). The studies were carried out in accordance with the thematic plan of scientific research of the Department of General and Irrigated Agriculture of Kuban State Agrarian University. The total area of the plot is 1008 m2, the accounting area is 672 m2. The number of rows in the plot is only 8, including accounting - 4. The arrangement of the plots is systematic. Three repetition. The predecessor is winter wheat. The calculations and observations in the experiment were carried out according to generally accepted methods. The technology of growing corn in the experimental plot corresponded to generally accepted for this zone and culture. The predecessor is winter wheat. Our studies have found that the leaf area was largely influenced by the density of plant standing – with the thickening of crops, it decreased by 2.9 thousand m2 / ha or 28.7 %, and there were practically no differences in the leaf area between different variants of seed treatment. Corn plants increase the accumulation of dry matter throughout the growing season. With an increase in the density of plant standing, the accumulation of dry matter decreases, and the studied protectants do not affect this indicator
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
The article reviews the results of the study of the influence of treatment of vines of Saperavi with lignohumate of grade "B" on its uvological and fruitful properties in the Anapо- Taman zone of the Krasnodar region
The article reviews the results of the study of the
influence of lignohumates of the grade "A" («LG-
АМ», «LG-А super BIO», «LG-А super L») on the
grape vines treatment of the Saperavi variety on the
quality must and wine in the Anapо- Taman zone of
the Krasnodar region. The technology of the
cultivation of grapes on the experimental plot
corresponded to the adopted in the JSC "Victory" of
Temryuk District, and was accepted for keeping of
fruit-bearing plantations area of non-covered
viticulture. Agrobiological works were carried out at
the optimum time and were of high quality type. Vines
of the third year of life, embodied by the scheme in 3,0
x 1,5 m. The forming was a one-sided Guyot with a
height of 60 cm in trunk. There was formed the same
load by shoots and clusters on the shoots. The
treatment of leaf surface bushes with the solutions of
lignohumates were conducted twice: 1st - before
flowering and 2 nd at the beginning of the formation of
berries (20 days after the first one). The spraying was
carried out in the early morning hours. The accounting
for the grape harvest and sampling to determine the
quality of must and wine (10 kg each variant) was
conducted in September 20, 2012. Technological and
physical-chemical analyzes were carried out in the
shop micro winemaking and accredited testing
laboratory of grape processing of the SSI NCZSRIHV
of RAAS. Preparations "LG-B Bio", "LG-B Super
Bio" and "LG-B Super A" as grape plant growth
regulators have equal and stable effect
In article the review of results of studying plant growth and development of maize, as well as features of the formation productivity of mid-season hybrid of corn Valentin depending on the variant of primary tillage (in common Harnes with Luvaram and Titus with Harmony) under conditions of sufficient moisture zone of the Central Ciscaucasia is given.
In article the review of results of studying a contamination of crops of mid-season hybrid of corn Valentin depending on option of the main processing of the and herbicide processing (in common Harnes with Luvaram and Titus with Harmony) under conditions of sufficient moisture zone of the Central Ciscaucasia is given.
The article reports in color on the characteristics of the three varieties and their clones that are common in Afghanistan. In the process of ampelographic screening of vineyards in Afghanistan, three varieties previously undescribed in Russian literature under the local names Aita, Gundyan and Shandyhani were discovered. Their identification by ampelographic and ampelometric characteristics made it possible to establish the original Aita variety, the Gundyan variety as a synonym for Guladan and Shandyhani as a synonym for the world famous Sultanin, or Kishmish. The described varieties are quite common in Afghanistan, reputable in economic returns and are still promising for cultivation in their country, where they are successfully used in the manufacture of dried products and high-quality diet juices. To identify the impact of various environmental conditions on the growth, development, quantity and quality of the crop, these varieties must be tested in all zones of different ecological and geographical areas of cultivation

The biological characteristics of plant growth and development of corn, as well as the formation yields of maize hybrids of different maturity groups, the nature of variation in their productive capacity and economic efficiency of small primary tillage are discussed
The article reviews the results of the study of influence of treatment of Saperavi vines with growth promoters (Immunotsitofit, Krezatcina and HB-101ECO) on its productivity and quality in the Anapо-Taman zone of the Krasnodar region
