INFLUENCE OF THE SOIL AND THE CLIMATIC CONDITIONS OF THE FOOTHILL ZONE OF KABARDINOBALKARIA ON THE PERFORMANCE INDICATORS OF SYMBIOTIC CROPS, YIELD, YIELD STRUCTURE AND THE QUALITY OF LENTIL SEEDS

abstract 1181604043 issue 118 pp. 758 – 772 29.04.2016 ru 528
In the leached black soils of the foothill zone of the Kabardino-Balkarian Republic on the territory of training experimental plant of FSBEI HE Kabardino-Balkarian state agricultural university named after V.M. Kokova we have studied the effect of soil and climatic conditions of area of cultivation and application of micro – macro fertilizers, plant growth regulators and biological products on the crops of lentils, their impact on the efficiency and quality. It is proved that in general, the natural conditions of the foothill zone are favorable for cultivation and obtaining high yields of major crops. The analysis of meteorological conditions of the area (typical for the whole area) shows that there are great reserves and opportunities to obtain high and stable yields of lentils grains. These morphological, genetic and agrochemical parameters of leached chernozem growing zones suggest the soil favorable to the growth and development of lentils. On average, during the years of studies, the number of plants on which we had marked tubercles, on the example of Rauza varieties in the background variant, was 63.7%; the use of the drug called Agropon C in combination with sodium selenite increased by 15.2% the number of plants with root nodules. Increasing the number of plants with root nodules was accompanied with increasing the number and weight of nodules per plant by 8.1 pc. and 10.1 mg. respectively. The highest yield - 2.66 t/ha under experimental conditions was obtained in the form of joint use of the drug Agropon C and sodium selenite with a seeding rate of 2.2 million viable seeds per hectare, which is higher than the reference version for this seeding rate by 0.46 t/ha or 17.3%. The maximum value indicators of protein content in the seeds and collecting the protein per unit area reached with the use of joint application of Agropon C and sodium selenite, where we achieved the seeding rate of 2.2 million of germinating seeds per hectare and made up 29.6% and 787 kg/ha, respectively

abstract 1181604044 issue 118 pp. 773 – 782 29.04.2016 ru 702
In our country, great influence is given to the production and consumption of agricultural animals' meat with high consumer qualities. In this regard, the livestock producers, particularly pigs, are to increase production and improve product quality. Works on using some natural mineral complexes - bentonite and zeolites as a source of macro - and trace elements are performed. The aim of the research is to study the effects of bentonite feeding with free access on the meat productivity and hygienic meat quality of young pigs for fattening. Best effect on the slaughter indexes of fattening gilts had bentonite feeding with free access that resulted in significant superiority of the animals in the experimental group over the control counterparts on pre-slaughter live weight, slaughter weight, chilled carcass weight, slaughter yield, carcass length, the "muscle" eye area and the backgammon weight. More favorable effect in the longest muscle on the dry matter and protein synthesis was provided by bentonite feeding with free access. Due to this, the gilts of the experimental group were in significant advance of their control counterparts in concentration of dry matter and protein in meat. Along with this, the longest muscle of young pigs on fattening in the experimental group had the highest protein value, as according to the protein-qualitative indicator the animals of this group were in significant advance of the control counterparts. Feeding bentonite clay with free access had a strong detoxifying effect that is against control counterparts of gilts in the experimental group showed the significant reduce of lead, zinc and cadmium concentrations in the meat

abstract 1181604045 issue 118 pp. 783 – 793 29.04.2016 ru 690
For further increasing pork production and to increase its quality it is necessary to provide complete and balanced feeding of young pigs for fattening. The special place takes the issue of satisfying their physiological needs in macro and micronutrients. The most cost-effective step in these circumstances is using bentonite clays as natural mineral supplements. The aim of this work was to study the effect of the addition of bentonite of Zamankulskaya field on the energy growth, digestibility and the digestibility of nutrients of the diet of young pigs. According to the results of the survey, the best productive effect was when ensuring free access to the bentonite, so that the young pigs of the 3rd experimental group vs control group had significant superiority according to gross and average daily live weight gain and feed products. According to the results of scientific and economic experience, it was found that with free access to the bentonite best economic and useful indicators were observed in the animals of the 3rd experimental group against the control analogs, as they had significant superiority in terms of absolute live weight gain and feed consumption per unit of production. During the physiological exchange of experience the most beneficial effect on the hydrolysis of complex organic compounds had bentonite feeding with free access of pigs. The result was a significant superiority of the experimental animals over the control ones in coefficients of digestibility of dry matter, organic matter, crude protein, crude fat and NFE. To improve the digestibility and absorption of nutrients in the diet of young pigs it is advisable to feed them with bentonite clay as natural mineral supplements with free access

MOBILE POLLINATION AS A PARADIGM FOR INDUSTRIAL BEEKEEPING

abstract 1181604060 issue 118 pp. 990 – 1000 29.04.2016 ru 737
The article analyzes the state of the domestic beekeeping. It is proposed, as a paradigm of the industrial beekeeping, to use honey and pollination systems. Over the past 25 years, because the hard economic reforms in the public sector, there was almost double reduction of honey collection. Russian beekeeping is in the hard situation because of the low yields and the use of outdated technologies. Russia's share in the global honey market does not exceed 1 %. A more viable was apiaries of private households. Beekeepers receive a basic income from the sale of honey. Meanwhile, in developed countries more than 60% of the income of integrated use of honeybees account for pollination activities. In modern conditions of the Russian vector of development of beekeeping should be its production and technological re-equipment, improving its bioecological principles and socio - economic transformation of the infrastructure sector. Using mobile honey- pollination systems, which provide bees with feed conveyor due to the frequent movement of the apiary, honey plant and beekeepers can reduce the cost of manual labor for loading and unloading hives. In the Kuban Agrarian University we designed the pavilion design (RF patent number 2,284,103 ), awarded with a silver medal of Concours Lepine (France, Paris ). Using a mobile pavilion allows to conduct all production functions: honey and pollination production and reproduction, ensuring the competitiveness of the industry

ANALYSIS OF THE IMPACT OF PREPLANT TREATING OF SEEDS WITH INDUSTRIAL ALTERNATING ELECTROMAGNETIC FREQUENCY (EMF PF 50 HZ) ON THE GERMINATION ENERGY OF MIDRIPENING SPRING BARLEY SEEDS OF THE VARIETIES OF VAKULA, VIKONT, RATNIK

abstract 1181604071 issue 118 pp. 1129 – 1138 29.04.2016 ru 554
The use of physical factors for preplant stimulation of seeds increases vigor, germination and improves the yield of agricultural products. One of the effective ways to improve seed grain quality is to impact on the seeds using physical factors, in particular, an alternating electromagnetic field of industrial frequency of 50 Hz (EMF of IF of 50 Hz). We studied the impact of EMF of IF of 50 Hz on the energy germination of mid-ripening spring barley seeds of promising varieties Vakula, Vikont, Ratnik. Carrying out the experimental studies we used a laboratory setup with annular pole points of rectangular cross section. Our disperse analysis resulted in data on germinative energy of seeds of spring barley varieties Vakula, Vikont, Ratnik, which showed that while treating seeds of spring barley by an alternating electromagnetic field of industrial frequency of 50Hz, we obtained the best values of germinative energy of seeds of Variety Vikont with a mode of processing being equal to W = 16%, T = 2 c, L = 0,03 m

SUNFLOWER LOW TEMTERATURE GROWTH RATE EVALUATION CONCERNING BREEDING FOR COLD RESISTANCE

abstract 1181604080 issue 118 pp. 1256 – 1266 29.04.2016 ru 379
One of the prospect directions in new sunflower hybrid development is cold resistance breeding in the emergency stage. Sunflower hybrids with uniform emergency and high rate growth under the low temperature conditions could allow to introduce sunflower in the new regions of our country and so to increase sunflower acreage. The aim of our work was to screen all sunflower available samples for growth rate under the low temperature and to select the best lines and initial material for future breeding. 140 sunflower lines of VNIIMK breeding and hybrid populations on their base were used as a material. Seeds of every sample were incubated during the 10 days in the thermostat under 100 С. Seed germination was evaluated for the each sample along with the seedling size. As a result the most prospective samples were selected for the future breeding work. On the second stage of the experiment one selected population was evaluated on the Breeding station of Vavilov’s AllRussian Research Institute of Plant Industry in the city of Pushkin (Leningrad region). Seeds from the best plants were obtained in this place and will be used for the new lines development. So the effectiveness of selection of sunflower samples for growth rate under the low temperature was verified and this method could be used to introduce sunflower in the new regions of our country with more severe climatic conditions

abstract 1181604082 issue 118 pp. 1282 – 1292 29.04.2016 ru 772
Development of confectionery sunflower openpollinated varieties (OP-varieties) is a prospect direction in sunflower breeding. High price level for confectionery sunflower seeds pushes forward the breeding program. Contrary, it is necessary to offer product, meeting consumer’s expectation for large seeds, good dehulling rate, proper oil and husk content. The aim of our work is to study morphometric peculiarities of seed structure for sunflower OP-varieties of different types – oil and confectionery, and to identify the best samples for using in the breeding program as an initial material. The study was done at All-Russia Oil Crops Research Institute (VNIIMK) named by V.S. Pustovoit (Krasnodar) in 2014 and 2015. Seeds of 6 OP sunflower varieties of VNIIMK breeding were used as a material (confectionery type – Dzhinn, SPK, Lakomka, Oreshek, Borodinskiy and oil-type – Muster). OP-varieties were sown by randomized blocks with 3 replications. Every plot had 4 rows. It was shown that seeds of confectionery sunflower OP-varieties had higher values of main traits (length, width and thickness) in comparison with oil-type sunflower. Seed traits analyses allowed identifying the best confectionery samples (Dzhinn and Oreshek) for future breeding
