OBSTACLES TO THE ESTABLISHMENT OF EFFECTIVE ASSOCIATIONS OF THE ENTERPRISES OF A DAIRY SUBCOMPLEX
Description
The article analyzes reasons that prevent the formation of stable and effective AIC associations of commodity businesses and processors of raw materials. Unbalanced process of the relationship between agricultural producers and processing plants have a negative impact on the economic situation of the organizations partners. Dictating low purchasing prices for raw materials by processing enterprises hinders profitability of agricultural producers. Purchase prices set by the processing enterprises of the dairy industry for milk, do not compensate for not only the production costs but also the losses from inflation. The rate of growth in energy prices is significantly higher than for livestock products, bringing its cost grew faster than sales prices. This leads to a dramatic reduction in milk production profitability. A paradoxical situation: on the one hand, dairies are facing an acute shortage of raw materials, on the other - exacerbated the problem of the sale of its milk producers at a reasonable price for them. The disparity between the purchasing prices for milk and retail prices for dairy products caused agricultural companies to seek alternative markets. Sharply increased sales of milk in the bottling of milk tankers, while many farms began to create their own recycling system

DEVELOPMENT OF FOOD PRODUCTS FOR RUGBY ATHLETES
Description
In 2016, the game of rugby for the first time included in the program Olympic Games with a team of seven players. It is well known that achieving significant results in speed-strength sports, which include rugby, is impossible without a high physical, psychological and neuro-psychic loads, which are always subject to the athletes during training and competition. Nutrition should occupy an important place in the training of highly-skilled athletes, rugby players. It is known that the decisive factor in Rugby is an adequate supply of carbohydrates (glycogen, muscle and liver, blood glucose). Prolonged exercise leads to a depletion of glycogen, thus may slow down growth meristematic tissue and worsen the body's recovery after the event. In view of the fact that rugby belongs to the speed-strength sports mind, there are additional requirements for carbohydrates with different chain lengths, easily digestible proteins and basic micronutrients. In the daily diet can not provide the athlete a sufficient amount of protein and carbohydrates, as well as the need to sustain their relationship. To solve this problem, we have to include specialized protein-carbohydrate foods that have high nutritional and biological value in the diet of athletes, rugby players, which are able to quickly restore glycogen stores and protein to prevent loss of muscle when intensive training. Thus, the development and practical implementation of specialized technology of the protein-carbohydrate foods for athletes, rugby players is actual and up-to-date

A METHOD FOR PRODUCING PECTIN EXTRACT FROM SOYBEANS
Description
Fruit shell - a waste of food and technical products. Only in rare cases they are used adequately to their rich chemical composition. Number of pectin substances in the structural components of the cell walls of fruit shells rather high. We investigated the quantity and quality of fruit shells contained soy pectin. The result of these studies was the proposed method for producing pectin extract from this kind of raw material. It describes how to work on the creation of a method for producing pectin extract from the leaf of soybeans. It's possible to extract pectin from the raw material, not previously used and pectin extract standard quality by applying advanced parameters of the process of conducting the hydrolysis-extraction. Valves soybeans washed with cold drinking water, dried and then pulverized. Then the purification is carried out by impurities. After that hydrolysis-extraction is carried out with a solution of succinic acid with heating. Separation of the liquid phase is carried out after completion of the hydrolease-extraction. We have developed and implemented as described above, the method solves the problem of soybean seed production waste

Description
There has been developed the design of the single disc centrifugal apparatus with the feed of the granular material along the blades. The scattering disc consists of blades, on the top shelf there is a flat disc with air intake windows (deflector). The purpose of the deflector is to eliminate the reflection of particles at the moment of contact with the blade and create a passing air flow to increase the range of flight of the particles. The analysis of the constructive scheme of the scattering disk showed that the amount of air coming inside the scattering disk is affected by the width of the window and the tilt angle of the deflector body. There was determined the dependence of the window width from the angle of the deflector body and height. Based on the analysis of the design there have been determined the limits of setting the window width and the tilt angle of the deflector body. The angle of the deflector body changes in the rate of 90 to 320 . Increasing the tilt angle of the deflector body leads to a proportional reduction of the window width. There have been set the intervals of variation of factors. There have been chosen the symmetrical composite plan of the second order and have been made a matrix of the experimental design. As a function of the response factor there have been taken a relative accuracy coefficient. The implementation of the experiment allowed us to determine the value of the regression coefficients. The adequacy of the regression equation to the equation obtained was performed by the Fisher test. It was determined that the equation adequately describes the technological process. For the analysis of this equation it was turned to the canonical form by moving the origin to a new point and turning at a certain angle of 14,950. The analysis of the canonical equations allowed the authors to determine the optimal values of the studied factors. The window width of the deflector is 22 - 25 mm, the angle of the body of the deflector is 8 - 120

ANALYSIS AND SELECTION OF WORKING MACHINES FOR PRE-TREATMENT OF THE SOIL UNDER GRAIN CROPS
Description
The best predecessors for sowing grain are grains and legumes, tilled cultures and perennial grasses. The precursor also determines the choice of the tillage type. The imperfection of the working bodies of the machines for soil treatment is the main reason for the increase in the complexity of preparing soil for sowing. In recent years, domestic manufacturers have been producing combined working machines that perform several technological operations in one pass. To prepare soil for sowing grain there have been selected disk units and working machines which were tested on the Kuban State Zonal Machine-Station. They fit well with the existing technology. It is rational to conduct tillage of soil for tall crops and perennial grasses by the disc cutter BDM-4×4. The disc cutter efficiently prepares the soil for seed bed cultivation on tilled precursors in one pass or two passes. It is efficient to conduct tillage on grain precursors by the stubble cultivator KSP-6, by the disc combined unit AKD-3 or DCN - 3.3. After grain predecessors the disc guns prepare soil for seed bed cultivation in two passes, and after perennial grass in a single pass. According to the results of the trials on the Kuban State Zonal Machine-Station the stubble cultivator KSP-6 efficiently prepares soil for sowing in one pass of the unit. The block-module cultivator MSC provides high quality pre-sowing cultivation simultaneously with sowing. There was proposed the method of equipping the unit so that it would provide usage of the data and technical characteristics of the tractor and physico-mechanical properties of the soil for which the technological operation is to be done. The proposed method determines the transmission ratio for which the amount of slipping does not exceed the permissible values in agro requirements. The value of the theoretical speed is calculated for the given transmission. Operating speed is determined taking into account the slip values

ANALYSIS OF DISK WORKING BODIES FOR MINIMUM TILLAGE
Description
Minimum tillage technology (mini till) is based on soil preparation for sowing by disk working organs. The spherical disc serves as a ploughshare and a blade and provides soil crumbling. There are two options for placement discs: a battery one on the X-axis with an individual bar. The working depth is adjusted by changing the angle of the battery attack. The distance between the tracks of the spherical discs on the common axis is 220 mm. In processing the soil with plant residues there is winding of stems on the axis which causes the disc jamming. The structural layout of the spherical disk on the individual axis with individual counter has none of these shortcomings. Spherical discs on the individual pole are placed on the frame in parallel rows. The working depth is adjusted by changing the angle of attack of each series. The number of rows on the harrow ranges from two to four. In the three-row harrow the front row is divided into two equal parts, with the working bodies being installed with the opposite direction of the bulge. The recommended working speed of the harrow is up to 12 km / h. The non-standard location of the disk of the mulcher on the spiral rack makes it possible to perform the following functions: crushing and incorporation of crop residues into soil, mulching. The number of rows of the mulcher is two or four, and the speed is of 15 - 18 km / h. The analysis of the data specifications of the harrows and mulchers with a different number of rows and different needs for the engine power of the tractor has been made. There has been determined the empirical dependence of the total number of disks upon the working width of the harrow and the mulcher. Dependence of the minimum power of the tractor upon the working width with different number of rows of the harrow and the mulcher was determined. It was found that at the same working widths, the double row harrow has the smallest value of the minimum power. At the fixed width, the double row mulcher has the highest value of the minimum power

Description
The created hybrids with new lines and testers were studied in 2014-2015, in the conditions of the central zone of the Krasnodar region and the Central Black Earth Region (Voronezh and Belgorod regions). As a parent forms for selection of early ripening and Medium early corn hybrids there were used lines of various groups of ripeness of the ident heterosis group: Kr 714 Kr 740 Kr 757 Kr 651 Kr and 602. All of these lines had high combining ability, and the line 602 Cr was used as a donor for a quick return of moisture from the grain when ripening. With the participation of the lines from the collection of the Institute and the donor line, we have created four hybrid combinations on the basis of which, the selection was received by the five-year selection of new source material for breeding new hybrids of corn. The assessment of comutiny capacity of new lines was performed using a linetesters of the genetic institute collections of 721MV Cr, Cr 801MV, Kr 654 Kr 244MV, Cr 602MV, Kr and Kr 802MV 752. Lines testers were represented by a heterosis group of Lancaster, Stiff Stalk Synthetic and wide lines with a genetic basis. According to the guidelines of the State strain testing of crops, and as a result of the field experiment, we have calculated the energy savings for new early maturing corn hybrids in comparison with the standard ones. Saving energy for equivalent fuel from new hybrids of corn comparing to the standard for 1 ha of crop was due to their grain productivity and varied depending on the conditions of the Voronezh region from 81.4 to 101.5 kg, in the Krasnodar region it was 79,0-97,9 kg

STUDY OF SOIL WATER REGIME ON VINEYARDS OF ANAPA - TAMAN SUBZONE
06.00.00 Agricultural sciences
Description
One of the limiting factors to obtain high yields of grape plantations in Anapa-Taman subzones with good quality is moisture. Grape plant adapts well to a limited amount of moisture in the soil. The penetration of roots deep into the soil horizons may reach 5-6 meters, provided with a moderate density of the soil and the lack of limiting factors such as the presence of ground water and limiting the content of toxic soluble salts. In the course of mathematical data processing we have established a trend of increasing average annual rate of precipitation in the period from 1932 to 2015. In the years when the amount of precipitation for the year exceeds the average long-term performance, the key amount of precipitation in the summer months in a downpour and in a limited area. Average annual amount of precipitation in the period from 1932 to 2015 was 519 mm, the minimum was recorded in 2002 (324 mm), the maximum - in 1981 (800 mm). Despite the general trend of increasing average annual rainfall over the years, moisture deficit is in the soil. Accounting of moisture saving dynamics in the soil in the 2015-2016's indicates the absence of moisture reserves. Optimal soil moisture values were observed only in May and June, and only half meter layer of soil. In the phase of growth and ripening berries (July, August, September) soil moisture content was much lower than the permissible value, which is comparable with the level of wilting point. For the stable-quality grape raw materials it is necessary to pay more attention to the water and the air regime of the soil
