The creation of breeding material with desired properties is a principal problem, the successful solution of which is now possible with the introduction of genetic engineering technology. We have carried out an evaluation of the source material on its basis to identify samples suitable for creating heterotic hybrids with a set of economically valuable traits, including resistance to the tomato leaf curl virus (TYLCV)
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
Obtaining maximum productivity and reducing production costs are the main challenges facing livestock producers in modern conditions. To achieve the effectiveness of the poultry industry, we carried out a research in the utilities sector of the Rostov Region, the purpose of which was to study the effectiveness of the use of a feed additive – bento-clay in the diet of ducklings grown for meat. In the research, we study the influence of various doses of the feed on the diet and growth of ducklings. Experimental research data showed that the introduction of bento-clay into the diet of ducklings as a feed additive allowed to increase live weight, average daily gain, the safety of ducklings, the mass of half-gutted and gutted carcasses, the yield of edible parts, and meat quality compared to the control group. Thus, bento-clay influenced the increase in the water-holding ability of ducklings meat, which contributed to the improvement of its technological properties. Therefore, at three weeks of age, the live weight of ducklings was 11.5% -18.2% more than ducklings of the control group, and at seven weeks of age this difference was 8.4-12%, respectively, and the average daily increase was 7.2 -14.1% with high safety
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
This article reviews the results of studies on the impact of the nutrition background and the use of the Bereke GN growth stimulator on the yield and quality of early ripe potato variety Marabell in southern Kyrgyzstan. Early potato yields were largely dependent on the use of the Bereke GN growth stimulant. The highest yield was identified with the integrated use of a growth stimulator provided the planned yield, and averaged 29.97 t/ha. Also, in the experiments conducted, the yield of early potatoes was largely dependent on the climatic conditions of the year under study. The structure of the crop of early potatoes has been analyzed. In case of complex application of growth stimulator, also in case of treatment of seed tubers with growth stimulant, thickness of early potato plants is increased and on average in three years there was an increase by 0.32 and 0.52 thousand bushes per 1 ha.
The structure and marketability of the early potato harvest were analyzed in detail, depending on the background of nutrition and the method of application of the Bereke GN growth stimulator
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

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
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
