In the conditions of Krasnodar region variety-rootstock combinations of plum Russian in the period of growth and fructification for the purpose of allocation of best of them for use in intensive technologies of cultivation are studied. The most weak, productive, fast-grown variety-rootstock combinations are allocated. They represent the greatest value for use in technologies of intensive type by production of fruits of Russian plum
The development of leaf spot pathogens (yellow leaf spot and septoria spot) has been studied in Belarus and North Caucasian Region of Russia. The resistant wheat cultivars to the pathogens have been revealed
Newest wine Muscat grape variety with colored pulp and juice Serra was breeded at Athens Institute of Viticulture (Greece) by P.Zamanidi and L.Troshin in 2007 by crossing the Ukrainian Odessa black variety (Alicante Bouschet x Cabernet Sauvignon) with the new Greek Muscat black berry Krimbas variety. According to the morphological and physiological characteristics it is included in the eco-geographical group of Black Sea Coast. Length of production period is 146-155 days. Strong growth of shoots (2,1-3,0 m). Percentage of productive shoots is over 90. Productivity is very high: 25-30 t / ha. Average weight is 350 g. Grapes characterized with high resistance to cold, drought and increased resistance to fungal diseases in comparison with varieties of Vitis vinifera. Flower is hermaphrodite, with the stamens and fully developed gynoecium. Cluster is medium, conical, sometimes with wing, medium density. Berry is small, round, blue-black, with a thick waxy coating. Peel of medium thickness, dense, durable. Pulp and juice are intensely colored, flavored with Muscat taste. Sugar content is very high, in the bushes at sun-dried bunches up to more than 40%. Prolonged preservation of crop on bushes. Variety is intended for manufacturing intensely colored dry red wines of excellent grade and high-quality sparkling, dessert, sweet and liqueur wines, and is suitable for the manufacture of high quality intensively colored juice with Muscat taste. When used in blends with other varieties increases color, full flavor and improves the bouquet of wine
Based on the analysis of 422 samples of compound feeds and grain for processing of different farms of the Krasnodar region, we have established the level of their natural mycotoxin contamination and also identified prevailing combinations. Regularities of the frequency of contamination have been presented as well
The effect of seeds shapes and sizes to field survival, plant stand, harvesting amount and structure of calendula crude drug were under investigation. Biological feature of calendula is heterogeneous seeds formation, when the same inflorescence forms seeds of various shapes and sizes. The following seeds fractions according to their shapes and sizes were used for sowing: uncinate shaped, crescent shaped as well as unseparated, including, except uncinate and crescent seeds, ring-form and scaphoid shaped seeds. It was discovered that maximum indices of laboratory, field survival of calendula seeds and plant stand were in conjunction with uncinate shaped seeds. Maximum crude drug harvest was in conjunction with the sowing seeds of uncinate shape, varied from years from 2.11 to 2.40 t/h; minimum- at unseparated seeds sowing, varied from years from 1.83 to 2.05 t/h. Crude drug extreme efficiency was determined in 1-3 gatherings by inflorescence weight gain and its quantity increase on the same plant. According to the size of elements of crude drug harvesting structure (inflorescence quantity and mass of the same plant, the same inflorescence mass) the variant of uncinate shaped seeds sowing had advantages
Small-leaved lime (Tília cordata) is wonderful species
of trees, producing honey. This tree species is not
cultivated in forest tree nurseries of Head forestry
department of the Omsk region for the purpose of an
artificial reproduction. Small-leaved lime grows wild in
Bolshyi Uki, Ust-Ishym and Tevris areas. This forest is
the basis for a honey production. Small-leaved lime
occupies a very small area, which equals 1,5 ha. Natural
reproduction of small-leaved lime in the Omsk
Pryirtysh district is a reliquiae. Questions of
reproduction of small-leaved lime have not been studied
yet. Shoots cloning of small-leaved lime has an
important practical value for areas of natural
reproduction. A technology of seed reproduction has
not been developed for the Omsk region. Complexity of
the matter is in the existence of a long and deep
physiological quiescent period of small-leaved lime
seeds. Experimental facts of small-leaved lime seed
reproduction has been described in this article. Results
of measuring of height and root neck diameter of oneand
two-year old plants have been shown. The
influence of putting young plants in the shadow on
their growth and development has been evaluated. It has
been shown that seedlings received from small-leaved
lime growing in the Оmsk State Agrarian University
Dendrology Park have large variation in the growth
and development parameters and the fact of casting
shadows on the plants truly affects the height of oneand
same as two-year old samples
In the article, we have considered the influences of agrarian production on environment and melioration on efficiency of land resources. The system of calculation of efficiency of performing meliorative actions taking into account inflation and costs of melioration has been offered
The research has revealed that sodium selenite, vitamin E and bifidumbacterine should be included into the ration of the agricultural poultry to increase its antioxidant status
The analysis of foreign and domestic methods to evaluate soil productivity sowings has been presented. It has shown the need for soil environmental assessment in the West Central Caucasus. The soil-environmental index and index scores for an experimental field of individual crops rotation, which will promptly assess the fertility of the soil, give recommendations for rational allocation of fertilizer has been given
Condition of flax growing branch development for the period from 1980 to 2007 is characterized in the article, modern ecological-economical problems of agrarian sphere of regional AIC are analyzed. Main trends of flax growing branch effectiveness increase
on the base of keeping and increasing of soil fertility were determined.
