The article presents the results of studying the influence of the reproduction zone on the sowing and yield quality of seeds of wheat varieties of soft winter selection of the NPC named after P. P. Lukyanenko. From the sowing qualities regulated by the state standard of the Russian Federation, the following indicators were studied in the experiment: viability ( % ) and weight of 1000 seeds (g). The P-1 seeds obtained in the NPC were sown in different agro-climatic zones of the region in the optimal time with the same seeding rate of 250 seeds/m2. The obtained seed material was supplied for the study of sowing qualities and yielding properties of learning in the nursery ground control. The yield quality of seeds significantly differed depending on the area of their production in the previous year. According to the results of four years of research, the seeds of varieties obtained in the Northern zone of the region had higher sowing qualities compared to seeds from other agro-climatic zones. The average seed viability for four years in the Tanya variety was 97.6%, in the Yuka variety-97.7% and in the Grom variety-98.0%. The largest mass of 1000 seeds was also observed in the studied varieties from the Northern zone of the region. Consequently, a more complete realization of the potential of the three studied varieties was also observed in the Northern zone of the region
The article presents the results of the study of pollen grains in different types and varieties of wheat and triticale selection by "National Grain Centre named after P.P. Lukyanenko". The varieties of winter soft wheat in the experiment were ranked by the length of the growing season, the height of plants and the level of frost resistance. In the analysis of the source material, the following characteristics were used as indicators: the shape, color, and size of pollen grains. In the course of research, no differences in shape and color were found, they differed only in size. According to the results of two years of study, it was found that the pollen of winter and spring triticale is much larger than that of various types of wheat. In ultra-ripe varieties, pollen grains are smaller (66.2 microns) than in varieties of other maturity groups. Semi-dwarf varieties (with two Rht dwarfism genes) form the largest pollen (70.1 microns).Winter wheat varieties with high frost resistance produce the smallest pollen grains
The article discusses scale formation problems of greenhouse complexes with geothermal heat sources. Two-circuit geothermal heat supply systems with intermediate heat exchangers are used to prevent equipment and communications scale. Fresh softened water is heated by geothermal heat and is supplied to consumer needs. The heat exchanger and primary circuit communications contacting with the geothermal heat carrier (geothermal water) are subjected to scale formation in the existing system. A scale formation of heat exchange surfaces reduces the efficiency of the heat exchanger and requires a periodic cleaning and causes a chain of economic losses in the production, transportation and consumption of heat. Currently, we use physical, chemical, biological and combined methods of scale formation prevention. The article also considers hypothesis about the effect of an acoustic-magnetic field on solutions. It was found experimentally, that the acoustic-magnetic field affects to characteristics and dimensions of salt crystals. The number of particles increases and solid phase dimensions decrease. A large number of microcrystals suspended in water are formed as a result of the nonchemical acoustic-magnetic treatment of geothermal water. These crystals do not stick to the pipe surface and do not settle to the bottom, may be filtered out and carry out by water flow from the system
The article reports in color on the characteristics of the three varieties and their clones that are common in Afghanistan. In the process of ampelographic screening of vineyards in Afghanistan, three varieties previously undescribed in Russian literature under the local names Aita, Gundyan and Shandyhani were discovered. Their identification by ampelographic and ampelometric characteristics made it possible to establish the original Aita variety, the Gundyan variety as a synonym for Guladan and Shandyhani as a synonym for the world famous Sultanin, or Kishmish. The described varieties are quite common in Afghanistan, reputable in economic returns and are still promising for cultivation in their country, where they are successfully used in the manufacture of dried products and high-quality diet juices. To identify the impact of various environmental conditions on the growth, development, quantity and quality of the crop, these varieties must be tested in all zones of different ecological and geographical areas of cultivation
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
The problems of automated control of the technological processes of crop production and the tasks of supporting the adoption of managerial decisions at each stage of the production cycle have become even more urgent in view of the processes of transformation, globalization and digitalization of the economy, which have recently become widespread. The agricultural sector of the economy of the Russian Federation is no exception, because agricultural products, especially crop production, are of strategic importance and are the basis of food security in our country. In this scientific project, the problems of agricultural enterprises of the Krasnodar region, in particular, in the field of management processes, its information and software, were investigated. At this stage, it was determined that the measures taken to increase labor productivity at the agricultural enterprises of the Krasnodar region and the automation of technological processes in crop production were not complex, therefore, they had a slight effect on the efficiency of the industry. Studying the IT services and software market made it possible to draw a well-founded conclusion that decision-making support processes in crop management, especially issues related to the justified choice of crop cultivation technology, rationalization of a crop rotation system, analysis of a history book of crop rotation fields, calculation of dosages of organic fertilizers for a deficit-free balance of humus, are not covered by the funds of software systems offered on the market. As a result, the demand for industrial analytical systems and, in particular, integrated automation systems for managing crop production processes for agricultural enterprises is forming in the software market. Therefore, the development and implementation of a computer decision support system for managing crop production processes, based on mathematical models for analyzing and evaluating the economic efficiency of crop cultivation technologies, crop rotation rationalization models, data analysis models for crop rotation field history books, models of optimal selection of crop protection products plants and fertilizers has become very relevant. These studies can be considered priority and highly demanded, as they are directly related to one of the fundamental directions of the modern development of agricultural production - the study of the problems of development and implementation of an integrated automated information system for crop management. The article is devoted to the theoretical justification and feasibility of the practical implementation of the software module for accounting and analysis of data from the e-book of the history of crop rotation fields, which is part of the developed automated crop management information system
The article provides a convincing argument for the preference of wool and fur products over artificial and synthetic textile fibers. It is noted that artificial fibers and synthetics have negative ionization, while natural wool has positive ionization. It is emphasized that negative ionization is far from harmless to humans. The analysis of the state of sheep breeding in the Russian Federation is given and this industry in the Rostov region is characterized against this background. The data on the number and productivity of sheep of the main age and sex groups, the production of young animals per one hundred ewes are presented. The characteristic of tribal resources of the country and region is given. The breeding base of the industry in the Russian Federation is represented by 205 breeding organizations, including 3 breeding and genetic centers, 44 breeding plants, 145 breeding reproducers and 13 gene pool farms, which contain 1389.8 thousand sheep (39.0 % of their total number in agricultural organizations and 6.6 % of the sheep population in farms of all categories), including 904.7 thousand Queens (35.0 and 6.2%, respectively). The breeding base of the Rostov region has eleven farms, of which 6 breeding plants for such breeds as the Soviet Merino and salskaya and 5 breeding reproducers. In addition to these breed resources, there are breeding reproducers for the qigai and edilbaev breeds in the region. Total number of breeding sheep in the region is almost 44 thousand.

The article provides a comparative analysis of assessments of the socio-economic development of the Krasnodar region from such well-known rating agencies as Standard & Poors, Moody’s, Fitch Ratings, which belong to the United States of America. The studied ratings are compared with the ratings of the national agency of the Russian Federation called “Expert RA”. The values of the established ratings are examined, as well as number of possible reasons why the ratings of the United States of America differ from the ratings of the Russian Federation, for example, economic and political reasons, and, subsequently, how these ratings affect the investment attractiveness of the Krasnodar region. The article explains positive and negative aspects of the integrated methodology used by international rating agencies, consisting of software and expert opinion, the level of access to it for study and analysis. We study another (local) source of information on the investment attractiveness of the Krasnodar region, which is a state institution, namely the Department of Investments and Development of Small and Medium Enterprises of the Krasnodar region. Options are proposed for improving the system of analysis of statistical data through methods that are based on a clear mathematical approach to provide an adequate assessment of the region and municipalities without the influence of subjective expert opinion
The article presents the results of studies on the influence of the conditions of the Piedmont horticulture zone of the Krasnodar region and the shape of the crown on the productivity of apple trees. Objects of study were trees of winter apple varieties Idared and Renet Simirenko grafted on MM 106 rootstock. The trees were planted according to the 5 × 3 m pattern. In the eighth year, the rounded crowns were transformed into flattened across the row (from the eastern and western sides of the tree) to crown width 2.0 ... 2.5 m. Orientation of rows was from east to west. The garden is located on the northern slope with a slope of 3 degrees. Scheme of experiment: option 1 - sparse-tier crown (control); option 2 - flattened crown. In the experiment, 2 variants; in each variant, 10 typical trees were taken. Repetition tree plot. The place of the experiment is Abinsky district of the Krasnodar region. Agrocounts of indicators of fruiting of apple trees were carried out according to generally accepted methods, statistical processing of research results was carried out by the method of analysis of variance described by B.A. Dospekhov. The results of our studies showed that flattening the crown of apple trees contributes to an increase in the number of fruits formed on them per unit volume of the crown in the variety Idared to 10.1 kg or 1.87 times, and per m2 of the projection of the crown to 15.5 kg or 1.72 times more than crowns without flattening. In the variety Renet Simirenko, the number of fruits according to the same indicators increases by 1.86 and 1.74 times. Also, when flattening crowns, the yield of apples from one tree in the Idared variety increases by 9.6%, and in the Renet Simirenko variety decreases by 7.7% compared with the control
