SOFTWARE PACKAGE FOR THE ESTIMATION OF THE SOCIO-ECONOMIC CONDITION OF THE SUBJECTS OF THE RUSSIAN FEDERATION

abstract 1602006012 issue 160 pp. 163 – 173 30.06.2020 ru 214
The article presents ways to estimate the socio-economic condition of the subjects of the Russian Federation using fuzzy production systems, discriminant analysis and neural networks. This study is based on the thirteen indicators of the socio-economic condition of the regions of the Russian Federation identified by RIA Rating rating agency. The goal of the work is to develop a software package combining the estimation methods above and allowing to get three alternative estimation options for a subject of the Russian Federation, using these thirteen indicators. The developed program assigns each region an estimation from the following set: AAA– the highest socio-economic condition, AA - very high, A– high, BBB– above average, BB– average, B– below average, CCC– low, CC– very low, C– the lowest indicators of the socio-economic conditions in the region of the Russian Federation. The software package is developed in Matlab and has an intuitive interface. The results can be used as an alternative to current methods of estimation of the socio-economic indicators

In the experiment, the effect of the use of an intelligent spreader on increasing the efficiency of nitrogen fertilizers used to feed winter wheat in ordinary chernozem was studied. The studies were carried out in the production conditions of land use by AO SHP Kolos in the Kochubeyevsky district. In this article, we examined the effect of a sprayer (Amazone UG 3000 Nova) and an intelligent mineral fertilizer spreader (Amazon ZA - TS - 4200) using touch sensors to determine the NDVI development index on the efficiency of nitrogen fertilizing winter wheat. Based on the experiments, it was found that, on average, over the two years of the study, the largest increase in the yield of winter wheat grains was noted in the variant with the introduction of ammonia nitrate in the first and second fertilizers using the intelligent fertilizer spreader Amazon ZA - TS - 4200 according to the NDVI - 6.53 t / ha. The highest structural indices of winter wheat grain yield were also noted in the variant with the introduction of ammonium nitrate in the first and second fertilizers using the Amazon ZA - TS - 4200 intelligent fertilizer spreader according to the NDVI index. So, the height of plants increased by 16.3 cm, the number of productive stems per 1 m2 by 37 pcs. The number of grains in the ear - by 5 pcs., The weight of 1000 grains - 0.8 g. According to the results of the experiments, it was established that in the conditions of land use by JSC "Agricultural Enterprise" Kolos "of the Kochubeyevsky District of the Stavropol Territory when planning the harvest of winter wheat - 6.5 tons / ha, it is advisable to use in the first and second top dressing of ammonium nitrate with a dose of 150 kg / ha, using the Amazon ZA - TS - 4200 intelligent fertilizer spreader according to the NDVI index

The aim of the following research is the studying of the efficacy in probiotic drug Probiolact (0.5% and 1.0%) usage, being in combination with Milkshake supplement. The given complex mixture is meant for medicative-phylactic purposes focused on the reduction of young ones death rate owing to gastro – intestinal diseases when neo-natal period. It is specified that the above-mentioned mixture affects the livestock indices. Thus, the average growth of baseline for the period of 30 days experimenting has been 7.4 kg, whereas in 2 tested groups it accounted for 10.3 kg and 11.6 kg, consequently. Therefore, the best possible daily phylactic doze of Probiolact (1%) and Milkshake mixture demonstrates the positive effect on the pro-cess of bifido- and lactoflora formation in calves’ intestinal tract due to normal flora cells quantity increase. With that, intestinal tract contamination level of disease-producing flora gets lower, and the natural resistance of cell-mediated immunity grows. Thus, two major problems of factory farming (i.e. the reduction of young death rate and surplus guarantee) can be solved with giving calves the mixture to drink, along with the first portions of colostrum, and during the following 30 days

BEEKEEPING AS A NECESSARY FACTOR OF APC DEVELOPMENT

abstract 1572003005 issue 157 pp. 52 – 64 31.03.2020 ru 210
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

TECHNOLOGICAL AND DESIGN PARAMETERS OF A PNEUMATIC SEEDER WITH A CENTRAL DOSING SYSTEM

abstract 1592005002 issue 159 pp. 14 – 21 29.05.2020 ru 209
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

RESOURCE CONSERVATION IN THE PRODUCTION OF SPRING BARLEY

abstract 1481904012 issue 148 pp. 49 – 56 30.04.2019 ru 208
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
