RESULTS OF RESEARCHES OF THE POSSIBILITY OF VIBRATION GRAIN SEPARATION FROM THE EAR
05.20.01 Technologies and means of mechanization of agriculture (technical sciences)
DescriptionEnhancing the operative parts of a threshing mechanism which are realizing direct mechanical impact on an ear and being in it grains it is impossible to achieve the considerable lowering and to completely exclude traumatizing grain. New methods of noncontact grain separation from an ear in case of the threshing need to be developed. These methods exclude direct mechanical impact of operative parts on grains. A perspective method of noncontact grain separation from an ear is the imposition to a culm with an ear of oscillating motion, perpendicular its axes. It is a resonance in different parts of an ear can cause. As a result of the pilot and theoretical studies it is set that when impart low frequency oscillations in the range 18…100 Hz corresponding to natural frequencies of its oscillations to a culm with an ear, it is possible to achieve corrupting of the ear or its separation from the culm as a result of a resonance. But grain separation, at the same time, does not come from an ear as the range of natural resonance frequencies of grain oscillations does not match the range of natural frequencies of a culm with an ear and has higher values. The analysis of results of theoretical researches shows that for noncontact grain separation from an ear without its traumatizing is the imposition to it high-frequency oscillations in the range 100 … 14000 Hz matching its natural frequencies of oscillations, which is proved to be perspective. The occurring resonance causes origin of own movements of grain that leads to its separation from the ear

05.20.00 Processes and machines of agroengineering systems
DescriptionThe small-scale intra-economic plants producing loose compound feed are outdated and require reconstruction by method of the modern process lines of compound feed granulation or extrusion adding. But such reconstruction requires a production stop. It is unacceptable for agricultural enterprises. The method of small-scale intra-economic formula-feed plant reconstruction is offered. The method consists in integration into composition of the plant of a modular process line for loose compound feed extrusion or granulation without stopping of production. The building for a new process line is created from the constructive modules representing metal frames with overall dimensions of a standard cargo container in which the equipment, ready to application, is installed. The combined multilevel building of a process line for granulation or extrusion is placed near the main factory building of the existing intra-economic enterprise. Buildings additional and the main production lines form two multilevel production factory building. The example of small-scale formula-feed plant reconstruction by method of integration a modular process line for granulation is explained. The line consists of modules for operational storage and dispensing of loose compound feed, conditioning and granulation, cooling, separation of granules. The traditional formula-feed plant of the fixed structure turns into the transformed system because the configuration of the new modular line can be easily changed. The offered method of reconstruction is perspective for application on small-scale intra-economic formula-feed plants as allows to reorganize without stopping operating production preparation of compound feed according to the modern requirements, having increased its quality and period of storage. Period of construction of the plant decreases from several months to several weeks thanks to creation of the building of the new line from ready constructive modules

RESOURCE CONSERVATION IN THE PRODUCTION OF SPRING BARLEY
DescriptionThe article discusses the possibilities and presents the results of research on the cultivation of spring barley with different production technologies in conditions of insufficient and unstable wetting of the south of Russia. Experimental studies were carried out in a stationary experiment with a four-field crop rotation with different variants of tillage (dump, flat-cut, layered, without tillage – no-till). It is established that the most expensive is the waste treatment of the soil (PN-5-35), and the least expensive is the technology excluding the impact on the soil. At the same time, the operating costs of labor and fuel consumption at no-till are lower, respectively, by 82-107, 23-48, 131-188% in comparison with traditional types of technology. Hectare fuel consumption with zero technology is 131-188% less than with traditional technologies and amounted to 22.8 kg / ha. The cost of production of spring barley using no-till is 8-41% lower compared to flat-cut, layer-by-layer, and dump technology and amounts to 285 rubles per cent. Calculated per 1 hectare, labor costs, fuel consumption, wages, fuel costs, deductions for renovation and repairs, as well as total operating costs for traditional basic tillage technologies increase, respectively, 1,23-1,48; 2,31-2,88; 1,30-1,56; 3,1-3,81; 1,65-1,85; 1,81-1,96; 1,83-2,09 times compared with no-till. The use of spring barley cultivation technology that excludes impact on the soil provides a fairly high efficiency even at lower yields

SEGREGATION OF THE PLANT HEIGHT AT INTERSUBSPECIES HYBRIDS OF THE SECOND GENERATION RICE
DescriptionThe article presents the results of the genetic analysis of the trait ‘plant height’ for six crosses involving the forms related to different subspecies of rice. There have been estimated the types of inheritance and a number of genes, which assist to determine this quantitative trait. We have found out that the variance of the trait ‘plant height’ is determined by 3-5 pairs of genes having additive and dominant activities and the degree of dominance reduces in case the variance among parental forms increases. The non-allelic interaction of the genes of the initial forms produces transgressive dwarf and tall forms. The cross ‘Lampo’x’Virazh’ showed the highest degree of transgression in ‘plant height’ due to short height of both parental forms (61.7%), but the frequency of transgression was larger than that of the cross ‘Lampo’x’Komandor’(17.6%). This combination (‘Lampo’x’Komandor’) produced more tall forms (up to 135 cm). The segregation of a great number of tall forms into F2 testifies that the parental forms of these hybrids vary in the allelic state of several pairs of genes, whose various combinations form phenotypes with a longer stem. Thus, the semi-dwarf feature of the varieties ‘Lampo’, ‘Komandor’ and ‘Virazh’ is determined by various non-allelic genes

TEMPERATURE REGIME OF THE TREATED SOIL LAYER
DescriptionThe article discusses the influence on the thermal regime of soil by agricultural activities, as well as the results of studies on determination of temperature in different soil layers under conditions of insufficient and unstable moistening of southern Russia. Experiments were performed in the experimental field in FSRI of the «ASC «Donskoy» (Zernograd, Rostov oblast) in terms of long-term stationary experience in the cultivation of soybeans with different technologies (traditional, zero). We performed the soil temperature checking at a depth of 30 and 60 cm using the temperature sensors with a measurement range from -40S to + 85S with a measuring accuracy of ±0,6S. For accumulation of data were used in the logger (weather station) Watch Dog 1400 series Micro. The purpose of the research was to determine and compare the influence of technologies of processing of soil on the temperature of the soil at different levels. On the basis of the conducted researches it is established that the average value of the ambient temperature stood at 23,8S a standard deviation of 3,1S. These figures are higher than the temperature of the soil at the background processed by traditional technology, and the raw background. The lowest average soil temperature at a depth of 30 cm (21,2S) recorded at zero background, obviously due to the presence on the soil surface of plant residues that protect the soil from solar radiation. Thus, the soil as a dynamic system converts the input signal (the ambient temperature) so that it is reduced in size and the rate of change (dynamic). These soil characteristics are determined by the technologies of soil processing

TECHNOLOGICAL ASPECTS OF SOIL DEPLOYMENT
DescriptionThe article presents the results of research on the impact of tillage technologies on the value of its density in the cultivation of winter wheat in conditions of insufficient and unstable wetting of the south of Russia. Experimental studies were carried out in the conditions of a long-term stationary experiment with a four-field crop rotation with different variants of tillage (dump, layer-by-layer, small, surface). The soil density was fixed at spring tillering of winter wheat and at the end of the growing season. Conducted analysis of variance shows that the soil has relaxation abilities, i.e. over time, it restores its properties by compaction ability, since studies conducted during the period of tillering of winter wheat show that Ffact. Ftable. (5,794,76), i.e. methods of treatment have an impact on soil compaction, which cannot be said for the case at the end of the growing season of winter wheat. The ability to restore its properties is a remarkable property of the soil, as it prevents them from over-compaction. The energy intensity of the compacted soil treatment increases to 30%, while the degree of crumbling is significantly reduced and its lumpiness increases. The most fundamental way to reduce the density of the soil is its timely loosening by working bodies of agricultural tools. Tillage methods affect soil density, the correlation coefficient between tillage methods and soil density varies between 0,929-0,979. The most radical way of soil decompression is exposure to it by a certain type of working bodies

06.00.00 Agricultural sciences
DescriptionThe use of resource-saving technologies for cultivation of basic crops does not make sense without the use of microelement fertilizers, biologics and growth regulators. All this fully applies to the technology of cultivation of the main bean culture – pea. In the current market conditions of agrochemical products, microfertilizers are presented in a wide range. Identifying the most effective of them at a price and yield increase is a defining task for agricultural producers. In this connection, the purpose of the research was to study the influence of biologics and growth regulators on the development and productivity of peas with the definition of their most effective them. The studies were conducted in 2014-2016 on the fields of the training and demonstration center on the introduction of resource-saving technologies of the IPCC APK VO "DGAU" in Zernograd, Rostov Region. As the studied drugs there were used Rizotorfin, Extrasol, Vigor Fort, Miwal Agro, Flavobacterin, Biogumat Kubansky, KU-8 Agrofon. As a result of the research, it was established that all the preparations studied showed a positive effect on the development of pea plants grade Angela. The yield gain was 0,34-0,56 t/ha in comparison with the control. The most effective are the following ones: Extrasol with a yield increase of 0,56 t / ha (14,6%) and a profitability level of 232%, Mival Agro – 0,54 t/ha (14,1%) and a profitability level of 192%, Biohumat Kuban – 0,55 t/ha (14,3%) and the level of profitability of 271%. A good level of profitability was noted at KU-8 Agrofon – 224%

EFFICIENCY OF USING COMBINED UNITS WHEN PREPARING SOIL UNDER WINTER CROPS
DescriptionIssues associated with the use of combined units in the preparation of the soil are relevant and of scientific and practical interest. Relevance increases when it comes to the cultivation of the main crop - winter wheat. In this regard, the presented results on the effectiveness of the use of combined units in the preparation of soil for winter crops are important. They are important primarily from a practical point of view. Experimental studies were conducted in the conditions of many years of stationary experience in the FSUE "ANC" Donskoy ", Zernograd, Rostov Region and in the Krasnodar region, LLC "Step". The efficiency of the use of combined units KUM-4, APK-4, developed at SKNIIMESH, now FSUE “ANC “Donskoy” in the cultivation of winter barley and winter wheat is considered. The technological process of tillage using combined units consists of several technological operations performed simultaneously. Disk working bodies chop plant residues and destroy weeds. At the same time, a network of cracks in the underlying soil horizons is laid. Next are flat-cutting working bodies that loosen the soil already at the set depth. There is a cutting of the root system of weeds, loosening the remaining non-loosened soil layer to the required depth, the formation of a flat bottom of the “furrow”, the separation of erosion-hazardous soil particles to the bottom of the furrow. Next, a roller - a compactor - compactor enters the work, which provides regrinding of soil lumps on the surface and subcompaction of the treated layer. The last in the process chain is a mulch roller, which ensures the formation of a compacted seed bed for seeds with simultaneous mulching of the compacted soil layer. The use of combined units in the technologies of cultivation of winter barley and wheat allowed to achieve a reduction in the number of technological operations by 1,5-2,5 times, an increase in the productivity of winter wheat by 0,4 t / ha (9%), a reduction in fuel consumption by 40%, operating costs 1,4 times with the economic effect of 1500 rubles / ha and the profitability of production of 140%

Description
The results of laboratory experiments on the effect of different concentrations of SkQ3 (10- (6'- methylplastoquinonyl) decyltriphenylphosphonium) on the rate of growth of spring barley seedlings of varieties Sokol and winter wheat varieties Kalym in normal and under inadequate moisture conditions, as well as data from field experiments on the effect of pre-sowing processing SkQ3 on the morphometric indices of spring barley varieties Shhedry, hard winter wheat of the Lazurite variety and soft winter wheat of the Lydia variety are presented. As a result of laboratory experiments, an increase in the growth rate of 14-day-old seedlings grown in solutions of polyethylene glycol was shown when treating the seeds with 2.5 nM and 25 nM with SkQ3 solutions. In the field experiments on the pre-sowing treatment of SkQ3 seeds, an increase in the morphometric indices of spring barley varieties of generic Lydia soft winter wheat and hard Lazurite winter wheat has been established, as well as an increase in the yield of winter wheat of both varieties as compared to the control
