DescriptionThe article gives a brief summary on the results of the introduction of rose varieties of climbing type in the central sub-zone of the Krasnodar region. Starting from the year 2000 in our institute a collection of roses from different garden groups, which includes 164 varieties, has been formed. Presently the rose varieties with long stems (from 2.5 m or more) are popular among specialists of landscape industry and floristlovers. Therefore we carry on introductions and study rose varieties of the groups of Rambler and LargeFlowered Climber. Rose varieties with valuable decorative signs, with enhanceable resistance to cold and drought-resistingness are selected. The valuable varieties and sources of the indicated signs are identified. Varieties of Albertine, American Pillar, Devichiy grezy are the sources of bright flower color; Bobbie James, Dorothy Perkins, Duc de Constantine - sources of long (more than 4 meters) of flexible shoots Warthburg - the source of early flowering. Variety New Daun - one of the few varieties of Rambler, which is characterized by re-bloom throughout the growing season in the conditions of the Krasnodar region. The indicative collection of several rose varieties includes the group of Large-Flowered Climber. A variety called Adzhimushkay is a source of large fragrant flowers of bright and early flowering. For the variety of Crimskiy Motive we noted the presence of a valuable feature - long flowering during the dry season (July-August). Flammentanz was included into the collection as one of the most winter resistant varieties of large-flowered. Promising varieties of the series of Super Rambler in the conditions of Krasnodar in the dry season formed short shoots, and flowers were not formed. Rose varieties included into the collection can be considered indicative of "anchor" genotypes, which are valuable for involvement into the selection process

FORMATION OF MICROBE-PLANT CONSORTIUMS OF THE RHIZOSPHERE IN ONTOGENESIS OF GRAIN CROPS
06.00.00 Agricultural sciences
DescriptionThe microbiological composition of the rhizosphere of the soft wheat (Triticum aestivum L.), the two-row barley (Hordeum distichon L.) and the sowing oats (Avena sativa) was studied. It is shown, that the total number of the rhizosphere microorganisms changes during the plant growth and development. The specificity of the microbial composition of the three studied cereal crops has been observed

THE FORMATION AND QUALITY OF MEAT OF CATTLE BREEDING AND POULTRY FARMING
06.00.00 Agricultural sciences
DescriptionIn order to ensure import substitution and threshold values of meat production, it is necessary to stabilize the livestock of animals and introduce intensive technologies. In conditions of arid steppes, the animals of Kalmyk, Hereford and Aberdeen-Angus breeds are best suited to stall-pasture technology. Before weaning from mothers at 7-8 months of age, their offspring is grown without additional feeding, just mothers’ milk. Therefore, the growth rate of suckling young animals rarely exceeds 850 grams of daily growth, while the live weight reaches 400-450 kilograms at the age of 18 months, with some advantage in favor of the young generation of Hereford breed. Using the intensive 9- months growing at the fattening complex with feeding from the self-feeders ensured the average daily gain in the Kalmyk bull-calves at the level of 1398 grams, and for the Aberdeen-Angus and Hereford breeds the growth is 1533 grams. The highest growth energy, live weight (661 kilograms), was with Hereford bulls. From bulls of the native Kalmyk breed with intensive technology of growing, a heavy body weight increase of 331 kilograms at 18 months of age was obtained. All tested samples of meat according to microbiological indicators comply with the requirements of the Technical Regulations

FORMING OF NITROGEN STOCK IN BASIC SUBTYPES OF BLACK SOILS IN THE SOUTH OF RUSSIA
06.00.00 Agricultural sciences
DescriptionDescription of nitrogen stock for black soils of southern and eastern European facies is given in the article. It is ascertained, that the black soil subtypes in the South of Russia have low content of mineral nitrogen (0,4-4,2%) and easily hydrolysable one (6,0-8,3), two times more than that of hard-to- hydrolyze nitrogen (13,4-16,4%), while the main part of nitrogen stock (74,4-78,9%) is found in unhydrolyzable fraction which practically does not participate in farm crop nutrition
