THE EFFECT OF CHELATED MICRONUTRIENTS ON THE SOWING QUALITIES OF SEEDS OF GRAIN SORGHUM VARIETIES

Posted in 2021, AGRICULTURE, Issue № 12 (114) December 2021 | 0 comments

Grain sorghum is a valuable agricultural crop capable of yielding a stable harvest at abnormally high temperatures. Due to drought resistance and heat resistance, grain sorghum is very popular in risk-prone farming regions. The area of cultivation of grain sorghum crops extends to Asia, Africa, South and North America, Europe and Australia. grain sorghum crops are cultivated for food and fodder purposes. In modern agriculture, resource-saving technologies aimed at reducing the cost of grown products and obtaining a consistently high crop yield of competitive quality present increasing interest. One of the elements of such technologies is the use of next generation low-cost fertilizers, which include chelated fertilizers. The article presents data on the effect of chelated micronutrients produced in the NGO “SILA ZHYZNI” on the swelling, germination energy and germination of seeds of grain sorghum varieties selected by the Russian Research and Design Institute of grain sorghum and Corn “Rossorgo”. The authors determine the effect of chelated micronutrients on the sowing qualities of seeds, namely on germination. The varieties that proved to be most responsive to both preparations were the following: RSK Partizan, Garant and RSK Kaskad.

ON THE NEW SPRING WHEAT-WHEATGRASS HYBRIDS CREATED IN THE DEPARTMENT OF REMOTE HYBRIDIZATION OF THE TSYTSIN MAIN MOSCOW BOTANICAL GARDEN OF ACADEMY OF SCIENCES

Posted in 2021, AGRICULTURE, Issue № 12 (114) December 2021 | 0 comments

The article presents the results of studies aimed at expanding the genetic potential of soft spring wheat (Triticum aestivum L.) by introgression of hereditary wheatgrass material into its genome using a “bridge” – new samples of ×Trititrigia (2n=56), which are donors of high quality grain. New hybrid plants have been obtained in the Department of Remote Hybridization of the Main Botanical Garden of the Russian Academy of Sciences. Crosses and further breeding work are carried out in two trajectories: “×Trititrigia × spring wheat-wheatgrass hybrids” and “soft spring wheat × ×Trititrigia”. All hybrids, starting from the first generations, are more or less fertile. A significant difference between the new hybrids and ×Trititrigia is the light threshing characteristic of the vast majority of samples from the first generations. In the combination of crossing “×Trititrigia x spring wheat-wheatgrass hybrids”, the study obtained and examined a crop of sixth generation samples (F 6). In the combination of “soft spring wheat × ×Trititrigia”, the fourth (F 4) generation of hybrid plants was obtained. Crosses of various varieties of soft spring wheat with promising samples of ×Trititrigia for breeding for quality are also contunuing. In both variants of crossing, there is an intensive formative process affecting different characteristics and properties of hybrid plants and providing great opportunities for further breeding work.

IMPROVING THE EFFICIENCY OF AGROECOSYSTEMS IN THE LOWER VOLGA REGION

Posted in 2021, AGRICULTURE, Issue № 12 (114) December 2021 | 0 comments

The purpose of this study was to evaluate the effectiveness of the crop rotations under study for grain yield in different years based on weather conditions. The highest productivity among all the schemes of the crop rotations was obtained in five-course and four-course ones with the inclusion of leguminous and late crops, where the yield of grain from 1 hectare of arable land amounted to 1.70-1.81 tons with the average productivity of all crop rotations amounting to 1.54 tons. Based on the research results, the study establishes that in order to achieve optimal efficiency of agroecocenoses in conditions of insufficient moisture, it is necessary to include late crops, such as corn and grain sorghum, which are able to produce stable yields in different years, in the structure of sown areas. It is also advisable to include leguminous crops in the structure of sown areas, which increase the efficiency of crop rotations and contribute to the preservation of soil fertility.

Posted in 2021, AGRICULTURE, Issue № 12 (114) December 2021 | 0 comments

The article explores the influence of different selection models on the dairy productivity of Holstein Black Pied cattle in a comparative aspect based on their comprehensive assessment over the entire period of use in the herd. For this purpose, the study selected two groups of cows (100 heads in each) based on the principle of paired analogs by the date of the first calving in the interval of up to one month. The first group included cows obtained by breeding three lines with maintenance for one of them through the mother’s father, mother, and father, the second group included cows obtained by breeding different numbers of lines. Individuals of both groups descended from the same bulls of the same breeding value. A comprehensive assessment of animals was carried out according to 9 indicators (live weight when grown at different age periods, basic body measurements, milk productivity for existing lactation, and average indicators for a number of lactation). Statistically significant differences between cows of two different groups were established by the following 11 indicators: the duration of the service period, the number of milking days and milk yield for the first lactation, the duration of the calving period in I and V lactation, the age of the second and third calving, milk yield for IV lactation and for its 305 days, average milk yield for a number of lactation, milk yield for one day of the calving period.

DYNAMICS OF HYDROCHEMICAL INDICATORS OF WATER IN A RECIRCULATING AQUACULTURE SYSTEM IN INTEGRATED CULTIVATION OF FISH AND PLANTS

Posted in 2021, AGRICULTURE, Issue № 12 (114) December 2021 | 0 comments

The article presents the results of studies of the dynamics of hydrochemical indicators of water in the integrated cultivation of fish and plants. A recirculating aquaculture system, with a volume of 1500 liters, contained the following fish: Acipenser gueldenstaedtii, Carassius gibelio, Tinca tinca, Cyprinus carpio, on the 36th day of the experiment, a growbox was connected to the system where Lollo Rossa Lettuce was grown. During the experiment, the water in the fish tank was not replaced or refilled. The dynamics of changes in the hydrochemical parameters of water when using the aquaponics module after connecting the growbox can be attributed to the fact that plants with a developed root system consume nitrogenous compounds. There are more active processes of the movement of carbohydrate substances in the system, the pH is stabilized. The accumulation of biogenic substances observed in the experiment indicated an insufficient number of their utilizers — plants.

THE USE OF CLUSTER ANALYSIS IN THE SELECTION OF SORGHUM × DRUMMONDII

Posted in 2021, AGRICULTURE, Issue № 12 (114) December 2021 | 0 comments

The main purpose of cluster analysis is to divide the set of objects under study characterized by a set of features into groups (clusters) that are homogeneous in the appropriate sense. A positive feature of cluster analysis is the ability to compress a large amount of information, systematize it, build a scientifically based classification, identify the internal relationship between the units of the population under study. The aim of the article is to identify promising samples of sorghum × drummondii according to the main economic characteristics based on cluster analysis for further use in breeding for heterosis in the conditions of Saratov Oblast. Grouping of samples allows for examining the composition of each cluster as fairly identical source material in terms of the severity of the indicators. During the period from 2015 to 2017, 32 samples of sorghum × drummondii were evaluated according to 12 economically valuable characteristics, which were subjected to statistical processing. At the 22nd iteration step with a Euclidean distance of 14.4, the samples were grouped into 10 clusters. Cluster differences were observed to be significant, except for the “1,000 Seed Weight” feature. The study distinguished clusters 1 and 5 based on the intensity of the initial growth. The second cluster is characterized by the number of differences in the parameters of the largest leaf, the width of the flag leaf, and grain yield. Clusters 3 and 4 did not differ significantly in most features. In the 6th cluster, differences were noted according to the following indicators: “the extension of the panicle leg”, “height at maturity”, “inflorescence length” and “length of the flag leaf”. The 7th cluster revealed differences in the width of the flag leaf, the width of the inflorescence, and grain yield. The 8th cluster distinguished itself by the parameters of the flag leaf and the yield of green biomass. In the 9th cluster, differences were revealed on the basis of: “height at maturity” and the parameters of “inflorescence”, “largest leaf”. The last cluster was distinguished by the greatest number of differences in the parameters of the largest leaf (in length 8 and 6 in width), grain yield and green biomass, the extension of the panicle leg. The results obtained are used in the selection of components of crosses in the selection of grass sorghum hybrids.

AN ASSESSMENT OF GENETIC AND REPRODUCTIVE RISK OF HOLSTEIN CATTLE

Posted in 2021, AGRICULTURE, Issue № 12 (114) December 2021 | 0 comments

The practical significance of the current article lies in substantiating the possibility and necessity of an individual cytogenetic assessment of high-producing cows. The presented individual approaches to cytogenetic assessment are virtually suitable for testing by the level of unconstitutional karyotypic variability. The established parameters can be used as breed standards for Holstein cattle. The levels of genetic risk (low, medium, and high) presented in the article show that the karyotypic status assessment confirms the presence of greater or lesser reproductive function disorders in high-producing cows. Compared with low and medium, the high level of genetic risk indicates an increase in the likelihood of reproductive dysfunction. As the research results demonstrate, if cows are divided into severe lesions of reproductive functions (abortion, stillbirths), differences in connection with the level of genetic risk become more noticeable. This is most pronounced in the group with a high genetic risk of 64 cows with a service period of more than 121 days, cases of stillborn calves with a prolonged indifference period of up to 51 days were noted in 5 cows (7.81%). In cows with an indifferent period of 51 days and above, such disorders as stillbirths and abortions were detected in 7 heads, which amounted to (10.94%).

Posted in 2021, GEOLOGY AND MINERALOGY, Issue № 12 (114) December 2021 | 0 comments

The relevance of the topic of the article is determined by the fact that while the deposit under study is currently being developed, the features of the supergenic distribution of gold are not taken into account. An analysis of the conditions of ore localization will allow for paying attention to the features of the distribution of gold in ore bodies. The methodology included field methods of mapping the deposit as well as the mineralogical-petrographic, tectonophysical, geochemical methods, and the use of the LMA-10 laser microspectral analyzer. The purpose of the study is to obtain data on the features of the distribution of gold in the supergene zone of the quartz-vein deposit. As a result, the authors distinguish morphological types of gold – scattered, primary and supergenic. The study also establishes quantitative values of gold in galena, pyrite, limonite and determines the nature of the distribution of the probity of gold at different depths of the deposit. Zones of oxidation, leaching, and secondary gold enrichment are identified and characterized both for quartz veins while also providing prognoses for other ore bodies of the multi-tiered mineralization of the deposit. Conclusions: the boundaries of supergene zones based on workings crossing ore bodies are established or assumed, recommendations for the development of the deposit are given.

BIOLOGICAL ACTIVITY AND TOXICITY OF SOILS POLLUTED BY WINTER DIESEL FUEL

Posted in 2021, BIOLOGY, Issue № 12 (114) December 2021 | 0 comments

The article presents the results of studying the biological activity and toxicity of soils during winter diesel fuel pollution.

The study carries out laboratory contamination of clean soils of various granulometric compositions (clay, loam, sandy loam) with winter diesel fuel (concentrations: 0.5; 1.0; 5.0%). Clean soils were used as a control sample. Incubation of clean and polluted soils was carried out in the course of one month. After a month of incubation, the residual content of petroleum product hydrocarbons in contaminated soils amounted to 456-6 287 mg/kg (7.1-18% of the initial concentration). Diesel fuel demonstrates a dual character on the number of bacteria, actinomycetes (stimulates by 0.1-4.2 million / g; decreases by 0.1-1.6 million / g). The number of fungi in polluted soils over the entire range of oil product concentrations decreases by 7.0-22 thousand/g. Catalase activity in polluted soils is inhibited. Microbial respiratory activity in polluted soils is 1-2 times higher than in uncontaminated incubated soils. The intensity of microbial decomposition of cellulose is suppressed by winter diesel fuel. A month of incubation shows the decomposition of 3-42% of cotton fabric in polluted soils. The germination of cress seeds and the growth of the root length of the seedling are reduced by 12-43% and 13-33%, respectively.

The study finds that contaminated soils remain in the category of “polluted” and “toxic” after one month of incubation. The study also identifies changes in biological properties in polluted soils.

AN ASSESSMENT OF THE GENETIC POTENTIAL OF STUD BULLS BY THE PRODUCTIVE QUALITIES OF THEIR MOTHERS AND DAUGHTERS IN THE SPA (K) “KUZMINSKY”

Posted in 2021, Issue № 12 (114) December 2021, VETERINARY SCIENCE | 0 comments

The realization of genetic potential largely depends on the productive qualities of animals. The current study carries out a comparative characteristic of the descendants of the leading lines of the Holstein breed. A comparative analysis of the productivity of daughters of different genotypes with the productivity of their mothers showed that within each line there are cows, the high productivity of which determines the value of individual bulls. The experience of using the genotype of stud bulls of different lines in order to improve the productive qualities of cows in this farm deserves attention.

It is impossible for breeding work to continue without the formation of breeding groups, i.e. selected animals with the best functional features according to a set of breeding indicators. The achieved level of development of dairy cattle breeding in Russia is considered high due to the updated methods of working with breeding high-producing animals. A number of studies by domestic and foreign scientists confirm the connection between the evaluation of bulls by the quality of offspring with a relatively rapid improvement of herds. Breeding work with highly productive cattle does not exist without the use of valuable breeding bulls with the high productivity of female ancestors. According to the results of studies determining the relationship of the breeding value of Holstein-Frisian bulls with productive longevity and the reasons for the disposing of their daughters (Adamczykk., JagusiakW., WeglarzA., 2021, Poland), the father’s breeding value class has a great influence on the disposal of cows on the basis of certain indicators; moreover, a greater percentage (50-73%) of disposed daughters on a number of key productivity indicators, as well as the duration of the service period and the number of somatic cells in milk, accounts for the average breed class bulls. Among the daughters of bulls of the highest (third) class, the lowest percentage of disposal was identified by the yield of milk fat and protein, while among the daughters of bulls of the first class, it has already been increased by 3-4 times.

One of the most important aspects in the education of foreign citizens is the processes of adaptation of students to new conditions in a new country. The purpose of the study is to assess the psychoemotional background of foreign first-year students that study using an intermediary language (English). Materials and methods. To assess the psychoemotional state of students, the study conducted a survey of 149 foreign students, A.T. Beck’s and U. Tsung’s standard depression scales were used; for the assessment of reactive personality anxiety, the survey used the Spielberger-Hanin test. Results. Most of the respondents examined corresponded to a moderate level of reactive (100 or 67.1%) and personal anxiety (88 or 59.1%). Close to a third of foreign students showed a high level of personal and reactive anxiety (32.2% and 29.5%, respectively). The majority of respondents corresponded to the norm level on the Tsung scale (136 people or 91.3%), mild depression was detected in 12 respondents (8.1%), subdepression was detected in 1 male student (0.6%). The overwhelming majority of international students corresponded to the normal level of depression on the Beck scale (96 people or 64.4%), mild depression was detected in 32 respondents (21.5%), moderate and severe depression was detected in 8 people. 5 students corresponded to the level of severe depression. There is a direct correlation between the level of personal anxiety and the level of depression (coefficient r=0.39 at the level of p<0.001 according to the Tsung scale, r=0.43 at the level of p<0.001 according to the Beck scale) Conclusions. The data obtained scientifically substantiate the need for adaptation measures for foreign students with monitoring of the psychological state.

Posted in 2021, Issue № 12 (114) December 2021, MEDICINE | 0 comments

Cardiovascular diseases (CVD) continue to occupy relevant positions within the framework of modern healthcare problems. This pathology is characterized by a high prevalence, frequency of complications and a high level of disability and mortality among the able-bodied population. An important fact that raises concern in the medical community is not only the continuing trend towards an increase in morbidity but also the so-called spread among the population who were previously less susceptible to the development of this pathology. This circumstance dictates the need to take into account the risk factors of CVD, which are characteristic of young age. As part of solving this problem, first of all, it is necessary to analyze the main risk factors affecting the development of CVD and develop scientifically-based preventive measures for young people with an underlying risk to develop CVD, taking into account the prevalence of risk factors in modern socio-economic conditions. To achieve this goal, it is necessary to activate the system of disease prevention, both at the state level and at the level of the practical health service.
