Authors: Perfilyev N. V. , Vyushina O. A. , Vlasenko A. N.
Published: March 2021

The effectiveness of long-term use of various basic tillage systems of dark grey forest soil in the conditions of the Northern Trans-Urals was established. Their impact on the efficiency of barley cultivation depending on the grain (spring wheat) or legume forecrop (vetch for grain) was determined. The research was carried out in a stationary experiment covering moldboard, nonmoldboard, combined, differentiated, stubble-mulch and surface systems of basic soil tillage. The experiments took place during the third–sixth rotations (1996–2018) of two grain-fallow crop rotations spread in time and space. The first crop rotation was: bare fallow – winter rye – spring wheat – spring vetch – spring barley, the second crop rotation: bare fallow – winter rye – spring wheat – spring wheat – spring barley. When cultivating barley following the legume forecrop (spring vetch), it was economically feasible to use basic tillage systems with the elements of minimization. It included non-moldboard and combined tillage with subsurface loosening by a plow with SibIME tines to a depth of 20-22 cm differentiated with stubble-mulch at 12-14 cm and disk harrowing at 10- 12 cm. These methods provided conditions for the formation of productivity close to the moldboard system and practically the same yield of barley, net income and energy efficiency coefficient. Without fertilizers, the yield was 2.97-3.03 t/ha, with the use of N40P40P40 it was 3.47-3.65 t/ha. When planting barley following wheat sown twice, the most effective was moldboard tillage system with a net income of 14.67 thousand rubles/ha without fertilizers and 22.75 thousand rubles/ha with fertilizers and energy coefficient of 2.65 and 2.75. The use of resource-saving tillage methods with repeated wheat led to a decrease in the yield of barley grain by 0.09–0.40 t/ha, and a decrease in the net income of barley cultivation compared to the legume forecrop by 31.0–44.1%.

The results of assessing the copper content in the bristles of pigs of Landrace, Kemerovo and Early maturing meat breeds are presented. The study was carried out on clinically healthy six-month-old animals in the farms of Novosibirsk and Kemerovo regions and Altai Territory. The conditions for keeping animals were standard with typical feeding. Elemental analysis of pig bristle samples was carried out by inductively coupled plasma atomic emission spectrometry. The data was processed using Microsoft Office Excel and Statistica 8 (StatSoft Inc., USA), including nonparametric methods. A decreasing ranged series was established according to the level of copper in the hair of pigs for Landrace → Kemerovo → Early maturing meat breeds. As a ratio, it is represented as 5.1 : 4.5 : 1. Copper in the bristles of Landrace, Kemerovo and Early maturing meat breeds amounted to 44.0, 39.0 and 8.7 mg/kg, respectively. The accumulation of copper recorded in the bristles of Landrace and Kemerovo pig breeds was 5.6 and 4.5 times higher than that of Early maturing meat breed (p ˂ 0.001). The Early maturing meat and Kemerovo breeds were characterized with the homogeneity of indicators; they had the smallest interquartile range and the ratio of the extreme variants. The study using Kruskal-Wallis criterion established that the breed affects the accumulation of copper in the bristles of pigs. Differences were registered in pairs: Early maturing meat – Kemerovo and Early maturing meat – Landrace breeds (p ˂ 0.001). The most similar results of studying animals based on cluster analysis were found between Kemerovo and Landrace breeds. Early maturing meat breed is relatively resistant to copper accumulation in the bristles. The data obtained can be tentatively taken as a physiological norm for the accumulation of copper in the bristles of pigs of various breeds zoned in Western Siberia.
Creation of the spatial metric for the image of an agricultural object
Authors: Kutsenogii P. K. , Kalichkin V. K.
Published: March 2021

The analysis of various approaches to forecasting complex multifactorial systems in conditions of uncertainty of external conditions is presented. It is necessary to develop these approaches in order to create adequate models of agricultural activities for their effective planning and management. A distinctive feature of agricultural production is a critical dependence on environmental factors, which cannot be accurately predicted. Regression modeling and analysis of time series used at present to solve this problem in difficult cases do not result in an adequate forecast of the dynamics of an agricultural object. As an approach, it is proposed to use the construction of the "image" of the system. This approach is classified as "nature-like", as it simulates a way of decision-making by a specialist on the basis of accumulated experience and intuition. The key parameter of this construction will be the correct choice of the metric (coordinate system). This approach is illustrated by an example of creating an image of a two-dimensional phenomenon in a one-dimensional coordinate system. As a result, an image is understood as an image of reality in a vector space of a certain dimension. The image in the authors' view is a reflection of reality in an artificially created metric, more suitable for understanding and analysis, but retaining the main (important) features and functions of the original object. Artificial intelligence techniques can be seen as tools for image creation and analysis. An important characteristic of an image is its predictive power, i.e. the ability to use the image in order to predict the state of a real object in the future period. An image retains its predictive power if the forecast obtained using this image corresponds to the data obtained when observing a real object. The image is formed in a suitable metric for solving a specific problem. The key metric parameter of the image of agricultural activity, suitable for forecasting purposes, is the minimum dimension of the vector space used, at which the predictive power of the image is retained to solve the problem.

The results of the analysis on the assessment of technical equipment of agricultural producers with mobile power facilities and technological machines depending on the area of cultivated crops in the Omsk region are presented. The state statistics data of the Ministry of Agriculture and Food of Omsk Region were studied for the period of 2008-2020. The total cultivation area of the region is 2881.2 thousand hectares. There was a slight decrease in the area under grain crops by 2.9 thousand hectares, under fodder crops by 75.2 thousand hectares, or by 0.14 and 13.2%, respectively. A significant change in the quantitative composition of the machine and tractor fleet is shown. An annual reduction in the number of tractors, forage harvesters and grain harvesters was noted. The number of tractors decreased by 2811 units, or by 26.6%. As of December 2020, the operation of 30.6% of grain harvesters and 56.7% of self-propelled forage harvesters does not exceed 10 years. A decrease in the number of agricultural tractors is connected with the use of a minimum tillage technology, a reduction in energy costs and funds for carrying out agrotechnical operations in comparison with traditional technology. Reducing the number of tractors and combines leads to an increase in the average load on the machine. This tendency leads to increasing the terms of the main agrotechnical operations, which affects the quantity and quality of the final product. The determination of the optimal composition of the tractor fleet should be carried out for each specific farm, taking into account local conditions, the structure of economic activity and its specialization.

Authors: Vlasenko N. G. , Burlakova S. V.
Published: March 2021

The results of assessing the effect of biological preparations and a seed disinfectant on the technological qualities of grain of soft spring wheat Novosibirskaya 31 are presented. The effectiveness of the use of biological plant protection products was studied in the field experiment, laid down in 2020 in the forest-steppe conditions of the Ob region. Pre-sowing seed treatment included the following options: control (without treatment); Trichodermin, P (Trichoderma viride, titer more than 6 billion spores/g), consumption rate – 15 kg/t seed; Sporobacterin, SP (Bacillus subtilis + Trichoderma viride, strain 4097), consumption rate – 0.5 kg/ton of seeds; Scarlet, ME, chemical standard (imazalil (100 g/l) + tebuconazole (60 g/l), consumption rate – 0.3 l/t of seeds. The use of the preparations contributed to an increase in yield by 0.40 and 0.52 t/ha when using Trichodermin and Sporobacterin, respectively, and by 0.08 t/ha when using fungicide Scarlet. In this case, the mass of 1000 grains increased by 0.84, 0.80 and 0.96 g, respectively, relative to the control. The preparations Trichodermin and Sporobacterin had a significant effect on the growth of grain in length and width relative to the control – by 5.4-6.9 and 9.6%, Scarlet – by 10.6 and 13.9%, respectively. Pre-sowing seed treatment contributed to the growth of such indicators of the caryopsis as volume (by 19.6–29.3%), surface area (by 12.1–19.2%), and sphericity (by 6.3–7.8%). To a greater extent, they increased with the use of fungicide Scarlet. Getting larger grain led to an increase in the endosperm content by 0.76–1.14%. A close correlation has been shown between the indicators of the mass of 1000 grains and the linear grain sizes (r = 0.92–0.98), as well as with the grain volume, sphericity and endosperm content (r = 0.98–0.99). Pre-sowing treatment of spring wheat seeds provides grain with improved technological properties.

Authors: Malyuga A. A. , Chulikova N. S.
Published: March 2021

Long-term studies (2014–2019) of the population dynamics of the fungus Rhizoctonia solani Küch. were carried out in the soil on the Purple Majesty, Vitelotte and Fioletovy potato varieties and preceding crops (potatoes, oats and tendergreen). The study was carried out in Novosibirsk region in the soil and climatic conditions typical of the forest-steppe zone of Western Siberia. To study the peculiarities of R. solani fungus population dynamics in potato plantations, soil samples were taken from under the plants during the entire growing season. The accumulation of rhizoctonia propagules in the soil was determined using the method of multiple soil pellets. The difference in the amount and rate of accumulation of the fungus R. solani on different varieties, as well as the influence of previous crops on this process, was established. Two peaks of the fungus accumulation were observed on the Purple Majesty variety: the first (48.7 propagules/100 g of soil) – during the full germination period, the second (57.2 propagules/100 g of soil) – at the end of the crop maturation phase. One peak was observed in the population dynamics of the fungus on Vitelotte and Fioletovy varieties, at the end of the ripening period (59.0 and 49.1 propagules/100 g soil, respectively). The smallest amount of R. solani fungus in the soil on average during the growing season was noted on the Fioletovy variety – 33.3 propagules/100 g of soil. In the Purple Majesty and Vitelotte varieties, this figure was 41.5 and 40.4 propagules/100 g of soil, respectively. When potato variety Agata was cultivated as monoculture, there was a rapid and significant accumulation of the fungus R. solani in the soil (from 34.6 to 126.8 propagules/100 g of soil). When this variety was cultivated following tendergreen or oats, the amount of the pathogen varied to a lesser extent (25.1–52.2 and 19.8–41.0 propagules/100 g of soil, respectively). No sharp increases in the number of propagative structures of the phytopathogen in the soil were noted.

Published: March 2021

The results of the analysis of yield and biological efficiency of single-species and mixed crops of cereals and legumes, depending on the cultivation zones, are presented. The study was carried out in the forest-steppe and steppe zones of Western Siberia and the forest-steppe zone of Eastern Siberia. The results were analyzed by means of Land Equivalent Ratio and the coefficient of aggressiveness. In the forest-steppe zone of Western Siberia, two-component mixtures with a seeding rate of 60– 75% of cereals (barley or oats) and 35–50% of legumes (peas) had an advantage in cultivation for fodder grain. The yield was 2.3–2.9 t/ha of grain with digestible protein content of 106–110 g per feed unit and the efficiency of the area use of 1.17 units. Peas mixed with wheat had the highest coefficient of aggressiveness (plus 0.53). In the conditions of the steppe zone of Western Siberia, two-component mixtures of barley and wheat with field peas are the most effective with a ratio of cereal and legume components of 60/50% of the total seeding rate of crops. The yield of these cenoses was noted at the level of single-species crops, and the nutritional value was 6–10% higher. Land Equivalent Ratio for this zone amounted to 1.21-1.3 units. The share of the legume component in the grain yield of three-component mixtures under unfavorable dry conditions of the steppe zone was registered insignificant. The value of the coefficient of aggressiveness of the legume component decreased to minus 1.58 and its share in the agrocenosis decreased to the utmost extent. The foreststeppe zone of Eastern Siberia is characterized by sufficient moisture, which contributed to a good grain harvest. The highest yield was provided by a mixture of oats with peas (4.85 t/ha) and oats with peas and barley (4.29 t/ha), with the Land Equivalent Ratio of up to 1.45 units and the coefficient of aggressiveness close to zero. In this zone, there are favorable growth conditions for binary crops.

Published: March 2021

The results of the application of environmentally friendly methods of potato pest control are presented. Comparative field trials of insectoacaricides and microbiological preparations were carried out on potatoes of the recognized variety Yantar in the Primorsky Territory in 2018 and 2019. The object of research was the larvae and beetles of the potato ladybird Henosepilachna vigintioctomaculata. The tubers were planted at the optimal time for the region, late April – early May. The study used Fitoverm preparations based on aversectin C (50 g/l), Akarin based on avertin N (2 g/l), Batsikol based on the strain of Bacillus thuringiensis var. darmstadiensis (BtH10), Bitoxybacillin based on the strain of Bacillus thuringiensis var. thuringiensis (BtH1). The preparations were studied independently and with Corado insecticide. Potato plants were sprayed with the preparations once. Pest counts were carried out before treatment and after treatment on the 5th, 10th, 15th day on 10 potato plants in three replications in accordance with the approved methods. Bioinsecticide Fitoverm showed a high efficiency of 90.5–94.0% at the application rate of 0.16 l/ha. A single application of bioinsecticides for 15 days restrained the intensity of the pest development below the threshold level. The combined use of bioinsecticides and an insecticide against the potato ladybird provided a decrease in the phytophage population by 90.8–99.8% compared to the control variant (without the use of plant protection products). The inclusion of preparations of biological origin Fitoverm, Akarin, Batsikol, Bitoxybacillin in potato cultivation technology will allow to limit the number of potato ladybird and solve the problem of plant protection in an environmentallyfriendly way in the south of the Far East.

Published: March 2021

The results of the study on the specific prevention of infectious diseases in horses are presented. Methods have been developed to increase the immunogenicity of environmentally friendly vaccines against strangles, caused by the beta-hemolytic streptococcus – Sreptococcus equi. The work was carried out in laboratory conditions and horse breeding farms of the Republic of Sakha (Yakutia). The toxicity and immunogenicity of the vaccine was determined by conventional methods on young horses. Based on the study of the immunobiological reactivity of young horses, the use of immunomodulators in the development of inactivated vaccine preparations has been substantiated. Vaccines with immunomodulators were tested and registered in accordance with approved research methods for medicinal products for veterinary use. Polyribonate (polyvedrim) and culture liquid (fugate) from the bacterial strain Bacillus subtilis TNP-3 were used in the composition of vaccines as an immunomodulator. To prepare a vaccine against strangles, strains of bacteria Streptococcus equi H-34 and Streptococcus equi "H-5/1" were used, which were deposited in the Russian State Collection of Microorganism Strains of the Russian State Center for Animal Feed and Drug Standardization and Quality. After immunization with inactivated vaccines containing immunomodulators, the effectiveness of vaccines increases by 20% and reaches 90%. Vaccines increase the body's immunobiological reactivity. The most effective were the “Tabyn” vaccine and the vaccine from the Streptococcus equi strain H-5/1 with fugate, the Bacillus subtilis strain TNP-3. The polyribonate vaccine was approved in Russia (2000), the “Tabyn” vaccine is used in Kazakhstan (2018). These vaccine preparations, which ensure high antiepizootic efficacy, are environmentally friendly, since they do not contain toxic substances and antibiotics.

The development of any nation depends on its scientific and technological prowess which when pivoted on sound mathematical foundation helps acquisition of functional skills for productive contribution to society. However, students have difficulty in applying mathematical knowledge to science learning. This study investigated the influence of Mathematical Language Ability (MLA) and Students’ Parental Supports (SPS) on achievement in senior school science subjects in Ogun State. It adopted a survey research type with two research questions raised and six hypotheses formulated. Seven hundred and twenty students were randomly selected from six out of eleven public senior secondary schools purposively selected in Ijebu Ode Local Government Area, Ogun State. Three test instruments: Mathematical Language Ability Test (r = 0.85), Students’ Parental Supports Questionnaire (r = 0.75) and Students’ Achievement Test (r = 0.78) were used for data collection. Data analysis using regression analysis revealed a significant influence of MLA on students’ achievement in the core science subjects. Similarly, the result indicated significant influence of SPS on achievement in science subjects. It is recommended that science teachers should be familiar with the language of mathematics since many of the science concepts involve the use of numbers, symbols, signs and mathematical expression for problem-solving.

Published: March 2021

Introduction: This study identified characteristics and diving practices of victims of fatal surface supplied breathing apparatus (SSBA) incidents in Australia from 1965–2019 to determine underlying factors and risks associated with these activities, better educate the diving community and prevent such deaths. Methods: A hand search was made of ‘Project Stickybeak’ reports from 1965–2000 and SSBA fatality data were compared to the Australasian Diving Safety Foundation fatality database. The National Coronial Information System was searched to identify SSBA diving deaths for 2001–2019. Extracted data were collated and analysed using descriptive statistics and Poisson Regression. A chain of events analysis was used to determine the likely sequence of events. Results: There were 84 identified SSBA-related deaths during the study period. Most victims were relatively young, healthy males (median age 33 years). At least 50% of victims were undertaking work-related diving, and 37% were recreational diving. Equipment issues, mainly compressor-related, were the main contributor, identified as a predisposing factor in 48% of incidents and as triggers in 24%. Conclusions: Preventable surface-supplied diving deaths still occur in both occupational and recreational diving, often from poor equipment maintenance and oversight. Incorrect configuration of the SSBA and lack of training remain on-going problems in recreational users. These could be addressed by improved education, and, failing this, regulatory oversight. The increase in health-related incidents in older participants may be controlled to some extent by greater medical oversight, especially in recreational and non-certified occupational divers who should be encouraged to undergo regular diving medical assessments.

Padang restaurants with specialty food rendang represent the Minangkabau's eating culture. The effect of modernization and media social in the eating culture has indistinct the origin of Minangkabau's eating culture and leads to the uniformity of design, mostly its space and physical elements in the traditional building. Whereas in the roots, eating activities according to the Minangkabau custom still carried out, such as Makan Bajamba. It is essential to study the origin of Minangkabau space and eating culture before learning design development. The main problem is how the relationship between space and eating culture in the life cycle of Minangkabau society carried out at Rumah Gadang. By using a mix-method, a qualitative approach is a case study at Rumah Gadang Istana Rajo Alam Tuanku Disambah and quantitative approaches using space syntax analysis on the dimensions of connectivity and integrity. Data were from literature studies, interviews, and direct observations on how Rumah Gadang facilitated eating activities. The result shows that Rumah Gadang effectively assisted the eating culture in the life cycle of its people. The space configuration in the process of eating activities is following the roles of women and men based on a matrilineal kinship system. The seat position rules for Minangkabau men from  the matrilineal kinship system divided Ruang Lepas into smaller areas, marked by walls, columns, and seprah clothes. All space of eating activities is a social space where interactions took place as a reflection of Minangkabau customs. The space syntax analysis clarifies the relationship between space and eating activities based on the matrilineal kinship system and the social interactions that occur with the space used. For future research, the space syntax analysis is useful as a perspective to learn the relationship between space and culture.

Authors: Priyatna Aquarini , Budhyono Rasus
Published: March 2021

Abstrak Artikel ini membahas dua cerita pendek, yakni Hair Jewellery karya Margaret Atwood dan The Blush karya Elizabeth Taylor. Kedua cerpen menunjukkan bagaimana tokoh perempuan menegosiasi dan mengupayakan subjektivitasnya dalam suatu konteks kultural dan sosial tertentu. Penelitian ini bertujuan untuk menunjukkan bagaimana subjektivitas perempuan ditampilkan melalui deskripsi fisik tokoh utama, perilaku serta pandangan tokoh tersebut terhadap dirinya, serta bagaimana tokoh mempersepsi tubuh dalam membentuk subjektivitasnya di dalam konteks budaya yang berkelindan. Dengan berfokus pada isu tubuh dan penubuhan para tokoh perempuan, isu kelas, relasi personal para tokoh perempuan, serta bagaimana mereka melakukan perlintasan yang terus-menerus antara ranah domestik dan publik, artikel ini berargumentasi bahwa kedua cerpen menampilkan tokoh perempuan yang berusaha merangkul dan membangun subjektivitas perempuan yang feminin dan feminis. Kedua cerpen menampilkan berbagai bentuk subjektivitas yang tidak ajek dan senantiasa berproses. Subjektivitas juga digambarkan berimplikasi kepatuhan, penolakan, dan transgresi terhadap norma gender. Kata kunci: cerpen, perempuan, subjektivitas, Elizabeth Taylor, Margaret Atwood Abstract This article examines two short stories, namely Hair Jewellery by Margaret Atwood and The Blush by Elizabeth Taylor. The two stories show how the female characters negotiate and develop their subjectivities within a certain cultural and social context. The article aims to elaborate on how woman’s subjectivity is presented through the physical descriptions of the main characters, their attitude and behavior toward themselves, and how their perception of how their body contributes to the formation of their subjectivity within a cultural and social context. By focusing on the issues of woman’s body and embodiment, the female characters’ personal relations, and the continuous traversion between domestic and public spheres, the article argues that both stories present women who strive to embrace and develop feminine and feminist woman’s subjectivity. Both stories present a varied forms of subjectivity, all of which is not fixed and is always in-process. Subjectivity is also portrayed to imply different degrees of acceptance, rejection, and transgression of gender norms. Keywords: short stories, women, subjectivity, Elizabeth Taylor, Margaret Atwood
PERAN SEMANTIK PREDIKAT PADA VERBA BERVALENSI SATU, DUA, DAN TIGA DALAM BAHASA SAMAWA DIALEK SUMBAWA BESAR/THE SEMANTIC ROLES OF THE PREDICATES ON VERB ONE, TWO, AND THREE SUMBAWA LANGUAGES IN THE SUMBAWA BESAR DIALECT

Abstrak Penelitian terhadap peran semantik bahasa Samawa masih belum banyak dilakukan. Untuk mendukung pengembangan dan pelestarian bahasa Samawa, penelitian-penelitian deskriptif seperti ini tetap perlu dilakukan. Penelitian ini difokuskan pada peran verba bervalensi satu, dua, dan tiga dalam bahasa Samawa dialek Sumbawa Besar dan bertujuan untuk mendeskripsikan peran semantik verba bervalensi tersebut. Teori yang digunakan dalam penelitian ini adalah teori sintaksis struktural. Data dikumpulkan dengan metode cakap dan metode simak. Data yang terkumpul kemudian dianalisis menggunakan me- tode padan intralingual. Hasil dari analisis data menunjukkan bahwa verba bervalensi satu melibatkan argumen-argumen yang secara semantik mencermainkan verba proses, tindakan, dan verba keadaan. Adapun verba bervalensi dua melibatkan argumen-argumen yang secara semantik merefleksikan verba tindakan, seperti pada sangode (mengecilkan), samasak (memasak), dan pina (membuat). Secara sintaksis verba-verba tindakan itu membutuhkan kehadiran dua argumen kalimat sekaligus. Sementara itu, verba bervalensi tiga yang secara semantik merefleksikan makna benefaktif membutuhkan kehadiran tiga argu-men kalimat sekaligus. Kata kunci: semantik, sintaksis, subjek, predikat, argumen Abstract Research on semantic roles in Samawa language has not been comprehensively done. To support the ef- forts of fostering and developing Samawa language, descriptive studies like this study are always needed. This study is focused on the role of verb valency one, two, and three in Samawa language, especially in Sumbawa Besar Dialect and aimed to describe their semantic roles. The theory used in this study is syntax structural theory. The data were collected using two methods realized by observing and listening to the conversation. The collected data were then analyzed using comparative method. Results of data analysis indicated that syntactically one-valence verbs require argument which semantically re ies process, ac- tion, and constant meaning. While two-valence verb requires arguments which semantically re ies action, such as verbs Sangode (to make something smaller), Samasak (to cook), and Pina (to make). These kind of verbs syntactically require two sentence arguments. While three-valence verb which semantically shows benefective meaning needs the presence of three sentence arguments.
