Nowadays, fruit trees are subjected to influence of abiotic stress-factors. The reaction of fruit plants on the influence of media plays an important role. Experiments were conducted in two (Northern and Central) fruit zones of the Krasnodar region since 2013 to 2015, there was shown the possibility of application of hydroabsorbents as a stable source of water supply of fruit trees in specific natural conditions of the South of Russia in the conditions of field experiment. There were shown the peculiarities of technological ways of water supply of fruit trees in specific natural conditions of the south of Russia. There was determined that the necessity in watering of a garden’s plots with the use of hydroabsorbents Ecogel-1 and Ecogel-2 with the supporting of soil’s moisture in 80% in Northern zone in the end of May, in central fruit zone in the middle of May. There was proven that the application of hydroabsorbents Ecogel-1 and Ecogel-2 guarantees the stable water supply in limits of 75-80% from NV since planting in apple-trees of varieties of Renet Simirenko and Golden Delicious grafted on the stock M9 and planted on the scheme 4,0 х 1,0 м during three years. The work of the system of “soil-roots-leaves” independently on weather and soil conditions is provided

INFLUENCE OF DURATION OF THE FIRST LACTATION PERIOD OF SOWS ON REPRODUCTIVE QUALITY

abstract 1221608079 issue 122 pp. 1163 – 1199 31.10.2016 ru 782
The article contains research results on the influence of duration of the first lactation period of sows on reproductive qualities. The authors have detected basic problems which reduce indices reproduction of purebred pigs of the breed of Yorkshire and hybrids of F1 (Yorkshire x Landras) under conditions of a new complex. It was found that because of the increase in duration of lactation period of the sows it is impossible to increase the safety of the piglets with a reduced live mass (from big nests and slow in growth) and improve the reproductive quality of sows. This method has been used in the economy what led to a notable improvement in the indices of pig breeding

THE SHORTAGE OF WINTER WHEAT GRAIN CAUSED by P. triticina

abstract 1221608085 issue 122 pp. 1284 – 1293 31.10.2016 ru 480
The article studies the influence of the interaction of two technologies of plant protection: breeding- immunological and chemical. The studies were conducted on the varieties and lines of soft winter, durum wheat and triticale, established in Krasnodar research institute named after P. P. Lukyanenko, and also, on varieties of an alien and foreign selection. When considering the correlations in the group of genotypes, forming a necrotic type of reaction to the introduction of the pathogen (the first group of varieties), the significant negative correlation (r - 0,76) between the change in the mass of 1000 grains and the number of unproductive stems formed by one plan was established. The model of the severity of brown rust pathogen in sparse crops of wheat has been collaborated. According to the model, the development of the pathogen in the tissues of the leaves of the host plant leads initially to a change in the relations of the productive and unproductive stems. The change of these parameters significantly affects on the variability of indicators such as the mass of grains from one ear, number of grains per ear and 1000 grain weight. Negligible volatility of weight for 1000 grains suggests that the major losses of productivity in the flowering stage are due to abortive flowers. This model can explain the increase in the mass of 1000 grains in some varieties for tolerance change experiments with the defeat of plants of P. Triticina on micro-plots

BREEDING EARLY-RIPENING AND MIDDLE-EARLY HYBRIDS OF CORN WITH LOWER HARVEST MOISTURE OF THE GRAIN WHEN RIPE

abstract 1231609007 issue 123 pp. 113 – 126 30.11.2016 ru 664
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

abstract 1231609016 issue 123 pp. 260 – 270 30.11.2016 ru 558
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

abstract 1231609024 issue 123 pp. 347 – 365 30.11.2016 ru 1087
Barley (hordeum vulgare) is a valuable food and forage crop. It is cultivated in the world on an area of about 60 million hectares. A major region of barley cultivation in the Russian Federation is the Southern Federal District. The variety is one of the main factors determining the demand for crop. To use the varieties effectively we must have a complex of economically valuable traits such as hardiness, resistance to lodging, disease and pest resistance. These traits make it possible to generate the harvest high and stable from year to year. The article is devoted to the analysis of winter barley varieties, created in the south of Russia from ancient times to the present day. The main achievements of the leading Russian breeding facilities and experienced breeders of scientists set out in chronological order.

EXPERIMENTAL RESEARCHES OF PARAMETERS AND REGIMES OF ELECTROTECHNICAL PROCESS OF OZONATING OF EGG STOREHOUSES OF POULTRY FACTORIES

abstract 1231609040 issue 123 pp. 605 – 619 30.11.2016 ru 526
The gaining of maximum amount of daily young animals in a greater extent depends on disinfection of incubation eggs which in complex of veterinarysanitary arrangements held in poultry factories on prevention and elimination of poultry infectious diseases takes an important part. The perspective of ozone application in industrial poultry breeding is conditioned with its advantages which it characterizes in comparison with other chemical substances. It was settled that ozone has a special ability to detain the growth of fungi on biological substrates, also the process of mould appearance on the surface of eggs’ shell even at 90% of relative moisture. At substantiation of parameters and regimes of electro-technological process of egg storehouse ozonation there were implemented the experimental researches. The general bacterial semination of eggs’ shell decreased on 94,1% after disinfection of incubaion eggs with ozone. The relative faults of experimental values from theoretical ones are 7%. In the result of production trials there were set the parameters of quality of the worked out electrotechnological process of egg poultry factory storehouse ozonation: time of regulation ‒ 8 minutes, dynamic fault ‒ 0,9, coefficient of overcorrection ‒ 4,5%, generalized integral mean-square index ‒ 10,6%. Obtained data testify against the qualitative regulation of allocation of concentration of ozone in a egg storehouse

MODERN ASSESSMENT OF NUTRITIONAL VALUE OF SORGHUM FORAGE

abstract 1231609052 issue 123 pp. 783 – 792 30.11.2016 ru 414
Sorghum is a source of concentrated, succulent and coarse forage. Its grain is used for making the mixed fodder and as the concentrated forage for swine, cows, sheep, horses and poultry. Sweet sorghum is successfully used for silage and haylage. Green chop of Sudan grass is used as fresh food for domestic animals and it’s used for making hay and silage. The nutritional value of the fodder is the way to meet the animal needs in nutrients, necessary for living. To determine the nutritional value of the fodder, oat fodder units and energy fodder units or exchange energy are used. At present the assessment of nutritional value according to fodder units is being revised, because it doesn’t give the true picture of the value of fodder nutrition and animal needs in nutrients. The general energetic nutritional value of fodder is considered as contents of all organic substances, supplied with fodder or with its energy. The nutritional value of fodder is valued according to the characteristics of its chemical composition, digestion of nutrients and general (energetic) nutritional value. The purpose of the work is to assess the nutritional value of fodder, obtained from the best sorghum varieties, as the food for different kinds of agricultural animals. Sorghum, used as fodder for poultry possesses the largest nutritional value. Among the grain sorghum varieties, the variety ‘Zernogradskoe 88’ has got the biggest value of fodder units. The green chop of Sudan grass and green fodder for silage of sweet sorghum possess the greatest nutritional value for swine. The varieties of Sudan grass ‘Krasava’ and ‘Arkadiya’ and the variety of sweet sorghum ‘Listvenit’ are the best varieties according to the contents of fodder units

abstract 1231609064 issue 123 pp. 917 – 929 30.11.2016 ru 501
The article analyzes the possibility of complex processing of one of the most important secondary raw materials of Krasnodar region – sugar beet pulp with the aim of obtaining a food product and enriched feed additives. Meanwhile, the use of environmentally safety technologies that cause minimal harm to the environment and human health is provided. One of the most valuable components of sugar beet pulp after extraction of sugar is pectin substance. Sugar beet pectin substances have high complexing ability and are used not only in food industry, but also in medicine. They are natural detoxifiers and antioxidants. Currently, only dry powder pectin is produced from sugar beet pulp and only by foreign producers. Making food pectin extracts from sugar beet pulp will not only reduce the number of processing steps, but also significantly reduce the cost of the final product. Food pectin extracts can be used not only as a standalone product in treatment and prophylactic nutrition, but also as an ingredient in the manufacture of soft drinks, confectionery and bakery, meat and dairy products, etc. The technology of producing a valuable component of feed bioproduct based on spent sugar beet pulp and a microscopic fungus of the genus Trichoderma is described
