06.00.00 Agricultural sciences
DescriptionCurrently, due to the risk of global warming because of increased concentrations of greenhouse gases in the atmosphere, carbon-deposit function of forest ecosystems, thanks to which stabilization of gas composition of the atmosphere takes place, has great importance [1]. Forest is one of the main components of the biosphere. Forests protect soil from erosion, provide stability hydrological regime of rivers, supply atmosphere with oxygen, biologically active substances, purify of harmful impurities, create optimal environmental conditions and play an important environmental role. However, because of intensive anthropogenic influence (unregulated logging, technogenic environmental pollution recreation) forest ecosystems are experiencing stresses at which irreversible processes of degradation of communities of economically valuable main forestforming species of both natural and artificial origin take place [6]. Evaluating carbon-deposit function of forest plantations, CO2 emissions to the atmosphere through the soil respiration must be taken into account, which can vary within wide limits. Productivity of forests is largely driven by carbon dioxide, released from the soil. Soil carbon dioxide provides demand of forest plants for photosynthesis. With increasing intensity of soil respiration, positive balance is maintained [2]. Based on the method of V.I. Tarankov for evaluation of carbon-deposit and oxygen-producing functions of wood cenoses [2], similar research is carried out in RSI "Kuban forestry", the KarachayCherkessia Republic

ASSESSMENT OF PEACH ROOT-STOCK RE-SISTANCE TO ABIOTIC AND BIOTIC STRES-SORS
06.00.00 Agricultural sciences
DescriptionResearches on assessment of peach-tree stocks stability to soil pathogens (nematodes, fungi and bacterial diseases) and to the excess of lime and moisture as well were carried out in the conditions of scientific-industrial enterprises of Agromillora Cotalana (Spain). Adaptation level of studied stocks to marked stressors was determined upon the results of this work. The steadiest to them are allocated. Various parameters of grades of a peach in these conditions are estimated

DescriptionThe article considers the results of the evaluation of the photosynthetic activity of peach trees in intensive plantations on clonal rootstock VVA-1 in the formation of improved cupped spindle-shaped crown. It is established that in the formation of spindle-shaped crown all the parts of it have just the right lighting, the leaves contain more chlorophyll, they are more specific and have real productivity

DescriptionThe experiments were conducted on bull-calf of Kazakh white breed at the age of 12 months. In the capacity of feed additives there were used "Yoddar-Zn", which consists of microelements as iodine and zinc in organic form, and the additive "Glimalask-Vet" based on organic acids (I gr.). A second group of animals received only a basic diet with "Yoddar-Zn» (II gr.) feed additives. In the organism of experimental groups of calves, the transformation proceeded more intensively for nutrient feed. This has contributed to increase the intensity of their growth, slaughter performance and the quality of the resulting beef. Bulls that received a ration feed additives had a live weight more on 35,9, and 20,4 kg, carcass weight after slaughter - at 22,27 and 11,47 kg, and the mass of flesh - at 20,9 and 8,50 kg., compared with the control. The average sample flesh of carcass fat content was higher by 1,25 and 0,74%, protein – 0,68 and 0,47%, iodine - at 39,30 and 26,71%. The animals of experimental groups in the edible portion of the carcass was synthesized as compared to control, more protein on 5,86 and 10,71% and energy - on 10,95 and 5,02%. The highest efficiency established at complex using both feed additives. Estimation of economic efficiency of use of these feed additives showed a decrease in cost and increase in profitability of beef production

PATRIS – A NEW GREECE-RUSSIAN WINE HIGHER QUALITY BLACK BERRY VARIETY
06.00.00 Agricultural sciences
DescriptionThe Patris variety is a hybrid, which was made as the result of Greece-Russian scientific collaboration in Greece by Panteley Zamanidi and Leonid Troshin in 2001 year by hybridization of Aigeorgitiko and Cabernet Sauvignon variety. By its morphological characteristics, it is included to the group of the Black sea varieties (convar. pontica subconvar. balcanica Negr.). The production period is 156-165 days. The growth of shoots is big. The yield is very high. The weight of bunch is 250 g. It has good frost resistance, drought resistance and higher steadiness to mushroom diseases, comparing with the parents varieties of Vitis vinifera L. The leave is middle, black-green, five lobes, deep divided, bubbles on the higher plate are low, the hairs are low on the upper side and intense on the bottom. The flower is hermaphrodite. The bunch is middle, cylinder conical or wrinkle, low density. The berry is middle, round, blue-black color. The skin is dense. The pulp is juicy with paslen taste. The sugariness of juice is high. The variety is used for making dry red wines of outstanding quality
