Description
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

Description
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

Description
The results of comparative analysis of three white muscat grades of grapes Viorika, the Muscat de Yaloven and the Muscat onitskan according to the biological indicators of fructification, productivity, quality of berries, mechanical structure of bunches, suitability for manufacture of direct extraction juice and dry wines are depicted in the article. All studied grades differ by high percent of fruiting runaways and high factors of fruiting and fructification. The highest factors of fruiting and fructification of runaways are reflected at grade Viorika, and the lowest - at a grade the Muscat de Yaloven. Biological indicators of fructification of runaways according to the length of a fruit spear are high and rather levelled at all grades. That is why, depending on bushes forming, it is possible to apply short and average (6-7 buds) length of vine cutting. Biological indicators of fructification of runaways from angular buds and sleeping buds are high enough, that shows to good regenerative ability of studied grades. Grades Viorika and the Muscat de Yaloven are tall, and the Muscat onitskan is average height. Degree of ripening of runaways at grades Viorika and the Muscat onitskan is good, at a grade the Muscat de Yaloven - satisfactory. Productivity of grades Viorika, Muscat de Yaloven and the Muscat onitskan is 77,94; 81,52 and 72,72 centner/hectares, and efficiency of runaway - 199,5; 193 and 221,9 with a significant difference between grades on both indicators. The exit of a mash at grades was 77,5-79,4 %. According to the contents of solids, sugars and acids, grapes of all grades correspond to requirements for manufacture of high-quality direct extraction juice. From grapes of these grades, it is possible to produce high-quality direct extraction juice under the name of ampelographic and blended grades. Sampling estimation of dry wines from grapes of these grades fluctuates from 7,6 to 7,8 points: 7,8 (Viorika), 7,7 (the Muscat onitskan), 7,6 (the Muscat de Yaloven)

DETECTED GRAPE VARIETIES OF AFGHANISTAN
06.01.01 General agriculture, crop production (agricultural sciences)
Description
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

Description
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
