RESOURCE CONSERVATION IN THE PRODUCTION OF SPRING BARLEY

abstract 1481904012 issue 148 pp. 49 – 56 30.04.2019 ru 213
The 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

STRATEGY OF RETRO INNOVATIONS IN IMPORT SUBSTITUTION

abstract 1531909026 issue 153 pp. 257 – 270 29.11.2019 ru 214
Unfavorable changes in exchange rates, sanctions restrictions on the supply to Russia of spare parts necessary for the repair and maintenance of previously imported equipment have led to a significant reduction in the service life of imported machinery and equipment. For the solution, the authors propose to implement the strategy of retro-innovations providing the development of new technologies maintaining in working condition of machinery and equipment in conditions of shortage of spare parts and consumables. To do this, it is necessary to develop technologies for the restoration of complex technical devices in order to extend their service life under the restrictions created by the financial market and sanctions policy. The study of the problem was carried out on the example of the operation of trucks of foreign production, the evaluation of engine life and analyzed the structure of the market. On the basis of the obtained results, a model was proposed, on the basis of which it is possible to form a plan for the production of spare parts for high-quality engine repair by domestic enterprises. The strategy of retro-innovations does not solve all the problems of import substitution, but it allows to increase the level of economic security of strategically important economic activities, it creates jobs and provides an opportunity to significantly extend the life of expensive and complex technical devices

The article considers the existing system of agriculture in the Krasnodar region. We also give the soil-climatic characteristic of natural-agricultural zones. There was studied the structure of agricultural landscapes of the region. It is concluded that in the agricultural production of the Krasnodar region approach to agriculture is focused only on zonal methods of land management, planning and organization of large agricultural enterprises. Whereas, the Land reform carried out in the Russian Federation since the 90-ies of the last century has made significant adjustments, both on domestic political and socio-economic relations in the life of society, and on land management provision of agriculture. Redistribution of agricultural land, the formation of new scientific approaches to farming systems, based on the principles of sustainability and self-regulation of agricultural landscapes, device of crop rotations, adapted to local climatic conditions are aimed at the reproduction of soil fertility and a positive balance of humus. In this regard, there were developed the proposals and calculated technical and economic indicators for the transition to a new, effective, scientifically based, adapted to local agricultural landscape conditions, high-tech balanced farming systems. According to developed proposals and recommendations, there was given the example of application in crop ten-field crop rotation for the central zone of the Krasnodar region, which is balanced in humus

BEEKEEPING AS A NECESSARY FACTOR OF APC DEVELOPMENT

abstract 1572003005 issue 157 pp. 52 – 64 31.03.2020 ru 217
The creation of stable agrocenoses requires ensuring a high pollination rate by maintaining a certain number of bee colonies per unit area. In Russia, over the past four years, the number of bee families has decreased to 3.1 million. For the full pollination of the entomophilous crops available in the Russian Federation, more than 7 million bee families are needed. The shortage of bees in Russia led to a massive import of bee packages from Uzbekistan, which significantly reduced the employment and profitability of residents in Russian agriculture. To ensure socio-economic well-being in rural areas, it is necessary to establish the formation of their own bee packages in the early spring. To do this, it is advisable to use instrumental insemination of bees, which allows to increase the productivity of the bee colonies by 25-40% and receive early bee packages with fetal uterus. It is necessary to carry out technical re-equipment of the industry, having established the production of mobile bee pavilions, beehive loaders, and honey pumping complexes. The development of beekeeping due to the manifestation of the multiplier effect will contribute to increasing the efficiency of the entire agricultural sector of the country

abstract 1592005002 issue 159 pp. 14 – 21 29.05.2020 ru 217
The article describes reasons for uneven distribution of seeds by pneumatic grain drills. For the theoretical justification of the operation modes of the pneumatic seeder, we have calculated the coefficients of the weight concentration of seeds in the air stream for different seeding rates and movement speeds. We have also calculated feed rate of seeds and planting performance of the machine for working width of 8.4 m. We have derived an equation of constancy of consumption of seeds, and the equation determining total pressure loss in the pneumatic conduit, emerging from the sum of the losses in the receiver, losses on the dispersal of the material after the receiver, and losses on the stopped movement of pneumatic mixtures

THE IMPACT OF PHOTOSYNTHETIC ACTIVITY OF EARLY POTATO SOWING IN CROP FORMATION IN THE CONDITIONS OF THE SOUTH OF KYRGYZSTAN

abstract 1521908013 issue 152 pp. 117 – 128 31.10.2019 ru 218
This article presents the results of studies on the impact of the fertilizer application rate and the use of the growth stimulant called Bereke GN on photosynthetic activities of early potatoes in southern Kyrgyzstan. Due to the lack of scientific evidence on the integrated use of fertilizers and growth stimulants in conditions of southern Kyrgyzstan, we considered it necessary to clarify the methods and standards for the use of the Bereke GN growth stimulant in the production of early potatoes in lowland areas on typical gray soil. In southern Kyrgyzstan, similar research in early potato technology is being carried out for the first time. According to studies, the crops of early potatoes possessed high leaf surface, which were subjected to complex treatment of the Bereke GN growth stimulator, accordingly its value was in the flowering phase of 41.2- 48.2 thousand m2. When the nutrition increases, a more powerful assimilation surface is formed. The highest level was 48.2 thousand m2 per 1 ha under the complex treatment with growth stimulator. The formation of tuber mass on 1 bush with the complex use of the Bereke GN growth stimulant showed a high intensity. With an increased nutrition, the Berke GN Growth Stimulator Integrated Test Variant increased the tuber formation rate, respectively the value was 182 g/bush. According to studies over the years of the experiments, the amount of dry biomass crops increased naturally, depending on the application of fertilizers and the use of the growth Bereke GN stimulant

MODERN TECHNOLOGIES FOR GRAPE STORING

abstract 1592005022 issue 159 pp. 319 – 333 29.05.2020 ru 219
The article gives a review of modern technologies of storage of grapes. The main tool for stabilizing the quality of grapes during transportation and storage is the use of sulfur dioxide (SO2), a gas that has properties that can inhibit non-enzymatic darkening, reduce the activity of enzymes, effectively control the development of Botrytis cinérea (a phytopathogen that causes gray rot) and acts as an antioxidant. Researchers pay particular attention to control the release rate of SO2, as it is important in the first stage storage to ensure supply of significant quantities of SO2 for a short period of time, which eliminates Botrytis spores that are present on the surface of berries and to stabilize the damages formed during transport and filling; the second step is to ensure a steady supply of the minimum quantity of the SO2, to ensure the control of microbiological spoilage. For a long storage time. To preserve the quality indicators of grapes during storage, it is possible to use a modified gas environment created in various ways, including through special types of packaging; forced saturation of the environment with gases such as oxygen, ozone or carbon dioxide. At the same time, to enhance the effect can additionally apply fungicides, antifungal ear Anti-mold®, etc. There are known technologies for complex processing of table grapes to combat post-harvest microbiological spoilage, which provide for the first stage of treatment with ozone or sulfur dioxide followed by spray treatment with Muscodor albus. An alternative to the use of SO2 is the use of essential oils and hypobaric treatment methods that ensure minimal environmental impact. Positive results during storage are provided by the use of medium-range ultraviolet radiation (UV-B) or short-wave radiation (UV-C), which positively affect the transcription of biosynthetic genes, providing an increase in the content of phenolic compounds and antioxidant activity of grapes, without affecting the content of dry soluble substances, the value of total titrated acidity and pH during storage. The analysis of modern technologies is of interest to practitioners and researchers who develop technologies for storing grapes
