GROWTH AND DEVELOPMENT OF SUGAR CORN DEPENDING ON NITROGEN FERTILIZERS
06.01.01 General agriculture, crop production (agricultural sciences)
Description
The article provides an overview of the results of a study of the effect of nitrogen fertilizers (sowing and top dressing) on the growth and development of sugar corn plants. The object of research was the mid-early hybrid of corn called Krasnodar Sugar 280 NE (FAO 280). In the experiment, 2 factors were studied: factor Ā - sowing nitrogen fertilizer (b / b (k), 15 and 30 kg.d.v / ha), factor B - root nitrogen top dressing (b / b (k), 15 and 30 kg.dv./ha). The total area of the plot is 20 m2, the accounting area is 10 m2. The number of rows in the plot is only 4, including accounting - 2. The plots are systematically placed. In the fall, the main fertilizer was applied in the background at a dose of N30P60K60, under plowing. Repeating four times. The predecessor is winter wheat. The counts and observations in the experiment were carried out according to generally accepted methods. Studies have established that the phases of “seedlings” and “5-6 leaves” did not depend on nitrogen fertilizers. The “panicle panning” phase in the variants with the introduction of nitrogen occurred 2 days later, and the phase "milk ripeness on the cob" - for 1 day. The height of the plants of the control variant was 202 cm. With an increase in the dose of nitrogen, the height of the plants of sweet corn increased. The maximum (12 cm higher) plant height was on the option using N30 for sowing and root dressing

GROWTH AND DEVELOPMENT OF CORN DEPENDING ON THE DENSE OF THE STATION OF PLANTS AND SEED DRILLER
06.01.01 General agriculture, crop production (agricultural sciences)
Description
The article gives an overview of the results of a 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 treatment. The object of the 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 subject of research is included in the thematic plan of scientific research of the Department of General and Irrigated Agriculture of KubSAU. 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. plots The plots are placed systematically. Repeating: 3-fold. The predecessor is winter cereal crops (wheat). The counts and observations in the experiment were carried out according to generally accepted methods. The studies have established that the duration of the interphase and vegetation periods of corn plants depended on the density of plant standing, and with the thickening of crops, it decreased, and protectants did not affect this indicator. In all phases of determination, the maximum height of corn plants was noted with a plant standing density of 80 thousand units / ha. The studied dressers Maxim XL and Maxim Quattro had practically no effect on height. The diameter of the second internode decreased with thickening of the crop

PLANT RESIDUES AND SOIL FERTILITY
06.00.00 Agricultural sciences
Description
In the article, the review of results of studying of an annual cycle of decomposition of the vegetative remains of crops, which decompose under favorable conditions of moistening and temperatures during an annual cycle decays, on 80 to 100 % is given, and their complete decomposition is observed in 2 years. Their positive impact on soil fertility – increase in fermentation activity, humification increase, lack of toxicity is thus noted

06.01.01 General agriculture, crop production (agricultural sciences)
Description
The article presents the results of studies on the influence of the conditions of the Piedmont horticulture zone of the Krasnodar region and the shape of the crown on the productivity of apple trees. Objects of study were trees of winter apple varieties Idared and Renet Simirenko grafted on MM 106 rootstock. The trees were planted according to the 5 × 3 m pattern. In the eighth year, the rounded crowns were transformed into flattened across the row (from the eastern and western sides of the tree) to crown width 2.0 ... 2.5 m. Orientation of rows was from east to west. The garden is located on the northern slope with a slope of 3 degrees. Scheme of experiment: option 1 - sparse-tier crown (control); option 2 - flattened crown. In the experiment, 2 variants; in each variant, 10 typical trees were taken. Repetition tree plot. The place of the experiment is Abinsky district of the Krasnodar region. Agrocounts of indicators of fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was carried out by the method of analysis of variance described by B.A. Dospekhov. The results of our studies showed that flattening the crown of apple trees contributes to an increase in the number of fruits formed on them per unit volume of the crown in the variety Idared to 10.1 kg or 1.87 times, and per m2 of the projection of the crown to 15.5 kg or 1.72 times more than crowns without flattening. In the variety Renet Simirenko, the number of fruits according to the same indicators increases by 1.86 and 1.74 times. Also, when flattening crowns, the yield of apples from one tree in the Idared variety increases by 9.6%, and in the Renet Simirenko variety decreases by 7.7% compared with the control

PRODUCTIVITY OF SUGAR CORN DEPENDING ON NITROGEN FERTILIZERS
06.01.01 General agriculture, crop production (agricultural sciences)
Description
The article gives a review of the results of studying the features of the formation of sugar corn grain yield depending on the application of nitrogen mineral fertilizers used for sowing and fertilizing. The object of research was the mid-early hybrid of corn called Krasnodarsky Sakharny 280 SV (FAO 280). In the experiment, 2 factors were studied: factor Ā - sowing nitrogen fertilizer (b / ud (k), 15 and 30 kg.d.v. / ha), factor B - root nitrogen fertilizing (b / ud (k), 15 and 30 kg.dv./ha). The total area of the plot is 20 m2, the accounting area is 10 m2. The number of rows in the plot is only 4, including accounting - 2. The plots are systematically placed. In the fall, the main mineral fertilizer was applied at a dose of N30P60K60, under the main tillage - plowing to a depth of 25-27 cm. Four-fold repetition. The predecessor is winter wheat. The counts and observations in the experiment were carried out according to generally accepted methods. Studies have established that the highest yield of ears of sugar corn in milk ripeness - 14.60 and 14.71 t / ha, respectively, was obtained on options with the addition of N30 when sowing + N15 or N30 in root dressing. A further increase in the dosage of nitrogen to 60 kg.d.v./ha does not lead to an increase in yield. The highest level of profitability was obtained with the option of sowing nitrogen fertilizer at a dose of 30 kg.d.v / ha in combination with nitrogen for top dressing at a dose of 15 kg.d.v / ha (N30 + N15)

Description
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
