THE GROWTH AND PRODUCTION ABILITY OF SHOOTS AT DIFFERENT VARIANTS OF CUTTING FRUITBEARING VINES
06.00.00 Agricultural sciences
DescriptionThe article presents the results of studying the impact of different options for cutting fruit vines on the growth and productivity of shoots of the grapes. The obtained experimental data indicate the excessive overload of vines with eyes and shoots when performing contour trimming bushes without normalizing the choice of shoots, in comparison with other variants of experience. A significant increase of eyes on the vines when performing contour cutting was because during this method of cutting, the cutoff is at a certain level all the shoots are horizontal on the arm vines. A big load of vines shoots when performing contour cutting has reduced the length of shoots at 48 – 51%, and leaf area developed on the shoots of 53 – 54%. While the lowest productivity was different shoots developed on the vines in 3 variant, because here the contour cutting vines was not accompanied by a subsequent breaking of superfluous shoots, which have overloaded the bushes shoots. At the same time, contour cutting vines with subsequent breaking of the normalizing excess shoots were allowed to grow for fruiting the bushes a sufficient amount of normally developed shoots with high productivity and good quality bunches

DescriptionThe purpose of the study was to examine a century of experience of growing of forest cultures of the Siberian stone pine in forest conditions in the region of the Middle Volga. To achieve these objectives, we have investigated old growth culture of Siberian stone pine in the conditions of fresh oak forests in the territory of Rootka forestry of the Mari El Republic. Culture of Siberian stone pine was planted after continuous tillage. The distance between rows was 2,5 m, step landing – 1,0 m. The site was divided into five options, depending on variations in the width of planting strip (I-48 m, II-44 m, in III-40 m, IV - 36 m, V - 32 m). The studies have shown that the Siberian stone pine trees, regardless of the variant, are characterized by good clean ability from twigs, which increases with decreasing of the width of the curtain. It can be noted that in the 100-year-old age, the average height of trees reaches of 28,7 m, an average diameter of 49,8 cm. Stock of forest reaches 795,3 m3 /ha. Best annual increase is observed in growing cultures of cedar in the wings with a width of 40 m and is 7,95-of 7,93 m3 /ha. Based оn the research, we have concluded that Siberian stone pine should be recommended for introduction into the zone of coniferous-broadleaved forests of the Middle Volga region. When creating crops, it is necessary to use larger seedlings and plant density is not more than 1,0 thousand pieces/ha, and the width of the planting strip shall be not less than 40,0 m.

DescriptionWe have selected a group of test animals and formed a set of techniques for the research. The article gives an evaluation of fattening qualities (precocity, average daily gain, feed consumption per 1 kg of gain) of purebred and crossbred pigs. We present the dynamics of body weight and body length for the experimental pigs, productive qualities, the thickness of back fat of experimental animals to achieve the 100 and 130 kg of live weight

GROWTH, DEVELOPMENT AND YIELD OF WINTER BARLEY IN THE CENTRAL ZONE OF THE KRASNODAR REGION
06.00.00 Agricultural sciences
DescriptionThe article deals with a combination of different methods of cultivation of winter barley on the background of plowing, and their impact on growth, development and crop yield. The main technological factors allowing implementing the biological potential of culture are adaptive variety, quality seeds, predecessors, sowing and harvesting, fertilizer, soil fertility, crop care, including protection from weeds, pests and diseases. Barley is the culture of versatile use, which is grown for food and feed purposes. Intensification of cultivation methods of this phenomenon is essential and significantly affects the grain yield of this crop. Under the natural fertility of the soil and favorable weather conditions for black earth of Kuban it is possible to get 3,0-3,5 tons per hectare of winter crops of grain, and this requires the creation of an optimal diet, because one of the main factors affecting the productivity of field crops, including one phenomenon are fertilizers. In addition, the level of soil fertility and protection system of weeds, pests and diseases has great importance. Since these types of issues are relevant for agriculture, we have carried out studies to identify the optimal combination of different methods on growth, development and productivity of a single phenomenon

THE ROTARY METHOD AND THE APPARATUS FOR INTRA-SOIL HOEING
06.00.00 Agricultural sciences
DescriptionThe essential new approach to soil processing taking into account its origin as a geologically disperse body is offered. The soil should be processed not only using its natural dispersion, but also optimizing this geological deposit taking into account decrease in its dispersion in process of a geological and biological sedimentation in the field of weight of Earth. The new technical solution is proposed for rotational intra soil cultivation. The problem is solved to transfer a torque to the tool being inside the processed geological body

DescriptionModels of model trees in the manner of equations for calculation of the current increase of trees at radius in cedar, mixed fir and pine plantings are received. At calculation of the current increase at radius and height using the diameter of a tree on height bosom without cortex, age tree and average distance from nearest tree on radius is recommended.
