GROWTH AND DEVELOPMENT OF SUGAR CORN DEPENDING ON NITROGEN FERTILIZERS

abstract 1592005001 issue 159 pp. 1 – 13 29.05.2020 ru 31
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

abstract 1572003007 issue 157 pp. 75 – 88 31.03.2020 ru 42
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

FEATURES OF THE DEVELOPMENT OF CORN HYBRIDS DEPENDING ON THE TERMS OF PLANTING AND TMTD-PLUS DISINFECTANT IN THE ARID ZONE CENTRAL CISCAUCASIA

abstract 1131509110 issue 113 pp. 1573 – 1588 30.11.2015 ru 676
There was given the review of the results of the study in the arid zone of Central Ciscaucasia, the influence of planting terms and presowing seed treatment by the drug called "TMTD-plus", containing the growth stimulator Krezatsin 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 middlematurity 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 was presented as southern black earth. 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, middle-ripe – 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 - two 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

DETECTED GRAPE VARIETIES OF AFGHANISTAN

abstract 1572003026 issue 157 pp. 346 – 367 31.03.2020 ru 33
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
