Description
The research work was conducted on the tomato hybrid F1 Мо 755 × L. esculentum var racemigerum (Lange) Brezh. The individual characteristics of the reproductive system of tomato F1 hybrid were studied for their further inclusion into the selection programs. The dynamics of these factors in regard to the clusters in the tomato inflorescence was investigated.

DESCRIPTION OF CERTAIN ASPECTS OF THE PRODUCTION POTENTIAL OF SOILS TAMAN PENINSULA
DescriptionThe work presents the results of the scientific research in the Taman Peninsula soil properties. We carry out the historic review of the studies in the Taman Peninsula soils, and its geological structure. We present morphological characteristics of the soil profile for the southern, calcareous, ultra heavy loam chernozem developed from the loessial loams and forming genetic horizons. The studies of the humus content in the soils show the associations between its percentage and the type and intensity of the agricultural use. Studies of the soils structure and composition demonstrate marked aggravation of the soils physical properties caused by grape growing. The best results of the particle size analysis have been achieved for the woodland soils. In woodlands, after their establishment, the soils under the grass and crown layers develop free of the anthropogenic impact. We register self-supporting growth of organic matter and natural processes of soil fertility recovery; therefore, such soils are characterized with a greater content of organic matter as compared to the soils under grape plantings cultivated in the monoculture regime. Reduced soil organic matter (humus) content in vineyards results from the disturbed biological interchange of the matter and increased anthropogenic impact causing erosion processes

FUNCTION FEED ADDITIVE OF CAROTE-NOID VEGETABLE RAW MATERIALS FOR POULTRY
DescriptionThe article is concerned with the use of functional feed additives from pumpkin fruits and alfalfa juice for the poultry industry. In the study of laying hen it has been found that the use of a feed additive in-creased pumpkin paste content in serum and egg yolk carotenoids is more than two times, and the concentration of vitamin A in these tissues increased slightly, not exceeding 20%. Livability and productivity of poultry increased and average expendable fodder per head per day decreased. Economic calculation showed that the use of pumpkin paste reduces the cost of production of eggs. The use of alfalfa juice coagulates in diets for broiler chickens resulted in an increase in the concentration of carotene in the liver by 22,7-46,8% relative to control. The juice addition also increased the content of vitamin A in the liver by 27.9%, increase the safety and efficiency of the bird. The authors draw certain conclusions from experiment results that the use of functional additives in poultry from the fruit of pumpkin and alfalfa juice is an alternative to synthetic vitamin preparations and produce a more environmentally friendly products

FORMATION OF SOILS STUDY AND THEIR FERTILITY; A HISTORICAL EXPERIENCE OF SOIL CLASSIFICATION
DescriptionThe roots of scientific knowledge on soil go into antiquity and are connected with the development of land management. A human had knowledge about soil as a friable layer of Earth, which was a subject o land management treatment until the time there were occurred the problems of shortage of arable lands, hunger and decrease of fertility, which caused the necessity of obtaining of more produce with less arable lands. The development of soil science was required for solving of these practical tasks. In postwar period there were carried out the large researches in the field of plant nutrition and application of fertilizers. For this period the active study of organic properties of soil occurred. The Dokuchaev’s study on genetic types of soil was the tuning point in the development of problems of soil classification. The further development of problems of soil classification were made on the basis of set genetic positions, thus the various approaches lighting the different parties of a classification problem took place. The soil fertility in force of its important functions for a long time is not only as an agronomic category but also as a social, economic, philosophic, and at the last time – ecological one. The modern understanding of function of fertility is reached with the help of mathematical modeling. First, it is necessary clearly to present the aggregate factors of fertility and their interaction between them and external factors

Description
The article presents materials on studying distribution and phytocenotic confinedness of relict steppe species of Astragalus angarensis. Astragalus angarensis is the endemic of the Angara region and Yakutia, it is a relict species. Three small isolated fragments express the area of species. The largest fragment was found in the Angara region; the smallest two fragments are occurred in the valley of the Lena river, in the southwest Yakutia near Olekminsk and in the central Yakutia, from Yakutsk to Bulgunnakhtaakh village. Ecological and geobotanical characteristics of habit area of Angara Astragalus is given; floristic content of community is studied. The described desertificated Krascheninnikovia, Psathyrostachys steppes and also Festuca, Agropyron, Koeleria and Artemisia communities with Astragulus angarensis confined to slope habitats, characterized by poor floristic content that gives evidence of low competitiveness of this species
