Эффективность использования куриного помета при выращивании зерна озимой пшеницы

In this paper, the possibility and effectiveness of using chicken manure as an organic fertilizer "Soil improver (UP-1)" is studied. "Soil improver (UP-1)" was obtained by adding the plant growth regulator "Mephosphone" to chicken manure. The drug "Mephosphone" is intended for the cultivation of grain crops, as well as the production of organic products. Experimentally, the prospects of using the drug "Mephosphone" to accelerate the processing of organic waste have been revealed. As a result of the research, field data were obtained on the cultivation of winter wheat of the Kazanskaya 560 Elite variety in the fields of JSC Agrofirma Ak Bars - Pestretsy. The introduction of chicken manure - "Soil improver (UP-1)", treated with the drug "Mephosphone" was carried out according to the described method. The local variety of winter wheat "Kazanskaya 560" Elite with a seeding rate of 280 kg/ha was used as an experimental crop. The predecessor was perennial herbs. Before the experiment and after harvesting, soil was selected for analysis from both experimental fields with an area of 300 hectares from 6 random plots at a layer depth of 0-20 cm. As a result of field tests, an increase in the yield of grain of the Kazanskaya 560 Elite variety was recorded when applying chicken manure. In the experimental plots, the yield was 33.5 and 36.0 c/ha. The grown grain with the use of chicken manure treated with the preparation "Mephosphone" meets the basic quality requirements and is practically not inferior to the grain of the control group, which allows it to be freely used for processing into flour of proper quality. Analysis of the indicators of experimental soil samples shows that they do not exceed the requirements of scientific and technical documentation. Thus, the resulting soil is safe for humans and agricultural production. The proposed technology for processing poultry waste will improve the environmental situation around modern poultry farms, reduce the use of unprocessed chicken manure as fertilizers, replacing it with higher-quality and environmentally friendly organic fertilizers formed as a result of anaerobic disposal of manure.

Agroecological and economic assessment of organic crop rotation in Polissia zone

For the organic production of plant products on sod-podzolic soil, a biologized short-rotational grain rotation was put to study: sorghum–oats–oats– vicot–oats–barley. In conditions of shortage of manure, the optimization of the nutrition system is carried out due to the by-products of grain and leguminous crops, oil radish siderate, the use of foliar treatment of crops with preparations of biological origin (microfertilizer Avatar, biopreparation BiocomplexBTU and liquid biofertilizer Volynski humaty), including, in the background mineral fertilizers allowed in organic production (P40K60 — phosphorite flour and potassium sulfate). The goal of the task was to investigate the influence of the biological fertilization system on crop rotation productivity, grain quality, soil fertility, and the economic efficiency of crop cultivation. It was established that, on average, during the 2021–2023 research, the maximum grain yield indicators were obtained for all factors of influence: pea-oats — 2.25 t/ha, oats — 1.88, vetch-oats — 1.66 and barley — 1.61 t/ha, the total crop rotation productivity under these conditions was 2.28 t grain units. It was determined that the protein content of oat grains was 9.1–9.8%, barley — 10.8–11.7%, the protein content of flax seeds was at the level of 18.2–19.0%, vetch — 22.9–23.8%, the lowest indicators were noted in the control. It has been established that in biological crop rotation due to 50% saturation with leguminous crops against the background of straw and siderate, a deficit-free balance of humus and nutrients is achieved. Due to the by-products of crops, 175 kg of humus accumulates in the soil annually, which ensures a simple reproduction of its fertility, and the additional application of fertilizers of biological origin helps to increase the humus to 350 kg, which ensures an extended reproduction of the fertility of sod-podzolic soil. Nitrogen comes at the expense of oil radish siderate, with by-products of leguminous crops and is biologically fixed from the atmosphere. Removal of phosphorus and potassium by crops is compensated by the supply of these elements with straw and siderate. Due to the disparity of prices, the cultivation of grain crops was unprofitable under all factors of influence, the profitability of legumes was 19.6–64.4%. The level of profitability of the general crop rotation for the treatment of crops with drugs was 6.5–14.8%, and the costs incurred for the purchase and application of phosphorus-potassium fertilizers did not pay off with the growth of crop yields.

ВИНОГРАДАРСТВО ЧЕЧЕНСКОЙ РЕСПУБЛИКИ В СОВЕТСКОЕ ВРЕМЯ (1954−1991), УСПЕХИ И ПРОБЛЕМЫ

The article discusses issues related to the unsuccessful introduction of viticulture in the administrative regions of the Chechen Autonomous Soviet Socialist Republic, where grapevine culture was new or non-traditional. These regions are Malgobeksky, Kurchaloevsky, Shalinsky, Grozny-Selsky districts. It has been established that the main reason for the spread of viticulture was the state’s desire to employ unemployed population and the high profitability of the industry. For this purpose, collective and state farms, which previously specialized in the cultivation of grain crops, feed production and livestock breeding, were restructured. The state allocated sufficient funds and material resources for the formation and functioning of a new sub-sector of the agro-industrial complex of the republic in these areas. However, hopes were not justified. The reasons that contributed to attempts to accelerate the introduction of grapevine culture in the “new” regions of the republic, as well as the failure of work in this direction, have been identified. An analysis of the activities of farms involved in the development of viticulture in these areas was carried out. Excesses of higher authorities have been established in planning for wine state farms the volume of new plantings of vineyards, achieving the planned yield and gross grape harvest, as well as planned targets for financial and economic indicators, and in the absence of proper consideration of soil and climatic factors and their compliance with the economic and biological characteristics of the grape culture. As a result, it was revealed that this crop was not adaptable to local conditions, which was reflected in the low survival rate of plantings, the high sparsity of plantings and their unprofitability for further exploitation. All wine farms were unprofitable. The factor of psychological incompatibility of the local population to this culture also had a certain influence. At the same time, all these undesirable phenomena intensified due to the fact that they coincided with the time of the weakening of the foundations of the state under the slogans of perestroika, the fight against alcoholism and drunkenness, and later − with the tragic events of the collapse of the USSR and their negative consequences. It is concluded that the widespread involvement of “new” regions in the development of viticulture was not a fully thought-out campaign. This led, in particular, to disastrous results: the vineyards were written off before they reached productive age. In the future, introducing grapevine culture here is not economically feasible.

Reproduction of Fixed Assets in the Part of Their Formation as an Object of Management of Enterprises of the Complex Agrarian Economy of Ukraine

The article focuses on developing proposals to justify management decisions concerning the formation of fixed assets of agricultural enterprises. This is considered a crucial component of management of the reproduction of fixed capital, given the complexity of the agrarian economy of Ukraine. The article outlines the spectrum of negative consequences at the micro and macro levels resulting from the disturbance of the proportions of reproduction of fixed capital in agriculture. It emphasizes the significance of enhancing management approaches and tools throughout all stages of the reproduction process.The reproduction of fixed assets is characterized, which determines its specificity as an object of management. The main objects of reproduction management in terms of financial, investment, operational, and marketing management are outlined.The task of operational management of the reproduction of the basic assets of agricultural enterprises, including the formation of an effective system of fund provision of agricultural production, has been determined. The management of material and technical support in the context of its adaptation to institutional, macroeconomic, industry, and market factors is considered. The study considers the factors of the complexity of the agrarian economy, the peculiarities of agricultural production, the market of industry technical means, and the market of agricultural services.The need to apply alternative options for the material and technical support of production in agricultural enterprises has been proven: the purchase of own machines and equipment or the use of agro-technological services from third-party organizations. The task of management is to justify the expediency of one of the alternative options or their combination, taking into account the size of the company’s land.An algorithm for determining the appropriate format of technical and technological support for production in agricultural enterprises is proposed. By applying the algorithm, calculations have been made for farms that specialize in the cultivation of grain crops. Proposals have been developed for agricultural producers regarding the optimal option for the formation of material and technical support for agricultural production depending on the area of their lands.

Characterization and Classification of Soil Along a Toposequence and its Implications on Crop Production in Dundaye District Sokoto, Nigeria

This study characterized and classified soils along a toposequence and its implications on agricultural activities in Dundaye district of Sokoto State, Nigeria. Two pedons on three (3) different topographical positions (summit, shoulder and foot slope) on a toposequence were studied. The Summit was on relatively flatland with an elevation of 283m above sea level; shoulder was a gently sloppy land with an elevation of 271m above sea level, while the foot slope was on a low land with an elevation of 262m above sea level. Morphological properties of the soils revealed that soils of the upper slope were shallow and perfectly drained and were generally sandy in texture. Those on shoulder were deep and well drained while those at the foot slope have subangular blocky structure with evidence of biological activities at the surface. Physical properties of the soils indicate a relatively high bulk density and high porosity. The dominant exchangeable bases were Ca and Na. The soils were slightly acidic in reaction with pH range of 5.3 to 5.4, 5.2 to 5.4 and 6.5 to 6.7. Organic matter content of the soils was generally low range from 0.33 to 0.37, 0.08 to 0.16 and 0.88 to 0.93. The soils were rated low in nitrogen. The results of available phosphorus show an irregular distribution in the profiles. The soils were rated having very low available phosphorus. The implication of these on crop production is that: the pH value was rated slightly acidic to neutral which favours the cultivation of grain crops. The low organic matter content recorded on most of the soils cannot sustain crop production on long time bases. Therefore, the study recommend that the organic matter content must be substantially increased through effective crop residue management; use of mineral and organic fertilizer; addition of more organic manure and crop residue for optimum plant growth.

Теоретичні основи оптимізації логістичних ланцюгів на ринку зерна

The purpose of the study is to study the theoretical basis for the formation and functioning of logistics chains in commodity markets and to model the logistics chain in the grain market in Ukraine. It is determined that the theoretical basis for the formation of logistics chains in commodity markets is the scientific achievements of the theories of world economic thought, in particular, the theories of detailed presentation, both descriptive and normative, are analyzed and structured. It is defined that theories of detailed exposition are theories that describe the cause-and-effect interdependencies of the elements of cooperation; descriptive theories – focus on the development and improvement of the conceptual and categorical apparatus; normative theories are based on the foundations of law. The authors’ own definition of the concept of «logistics chains of commodity markets» is proposed: it is a system of organizations, processes and actions aimed at the effective movement of goods from the manufacturer to the final consumer in the market; this system includes all stages of the supply of goods (production, transportation, storage, marketing, sales and customer service); the logistics chain in the commodity market focuses on meeting the needs of customers and maximizing their satisfaction through the rapid and efficient supply of the necessary goods; the main goal of creating a logistics chain is to provide the highest level of customer service, reduce costs and optimize all processes related to the movement and management of the movement of goods in the market. Based on the analysis of the theoretical basis for the formation and optimization of logistic chains, a scheme of the logistics chain in the grain market of Ukraine has been proposed. It includes 9 stages: from the cultivation of grain crops to distribution and sale either within the national market or on the international market. The number of stages of the logistics chain may vary depending on the hypothesis regarding its formation and further development.

Mycological and toxicological analysis of soil under the influence of crop cultivation technologies

The purpose of the research is to study the influence of various crop cultivation technologies on the structure of micromycete complexes and the level of microbial soil toxicosis. Extensive, organic and intensive crop cultivation technologiesin a six-field crop rotation on soddy-podzolic gleyic soil for 2021–2022 have been studied. To study the structure of the micromycete complex the deep seeding method, the spatial occurrence index of species, the Syorensen-Chekanovsky similarity coefficient and the significance indexwere used. To determine the microbial toxicosis, the method of the initiated microbial community according to V.S. Guzev was used. According to the results of the experiments, fungi from the departments of Zygomycota and Ascomycota were discovered, in 2021 – 10 species, in 2022 – 16 species. In 2022, the largest number of micromycetes was recorded under cereals with extensive and intensive technologies, in 2021, a high number of fungi was recorded in variants with annual and perennial grasses using the same technologies. The greatest manifestation of microbial toxicosis was noted in 2021: the germinating ability of test crop seeds on control variants –76.67-92.67%, when initiating a microbial community – 44.67-76.67%. The cultivation of grain crops by extensive and intensive technologies contributed to the greater manifestation of soil microbial toxicosis.

Эколого-экономическая оценка эффективности технико-технологических решений для ресурсосберегающих технологий возделывания зерновых культур в Сибири

The article analyzes and evaluates the effectiveness of grain cultivation in Siberia. The high energy intensity and poor execution of technological processes leading to their low efficiency and disturbance of the ecological balance have been revealed. It is necessary to improve the methodological approach and develop new mathematical models for the ecological and economic assessment of technological and technical solutions that reduce energy intensity as the main indicator with the predominant use of extensive technologies and reduce the anthropogenic load on the soil. Methodological and technical and technological solutions are proposed to assess the anthropogenic impact on the environment and reduce material costs in resource-saving technologies for the cultivation of grain crops in Siberia. The main economic indicators of the efficiency of cultivation of agricultural land are considered. The conditions of yield growth as a random variable and the main indicator of agricultural efficiency are shown. The rational structure of the three levels of technology intensity recommended for the conditions of the SFO is determined, and the model of mathematical expectation of full expenditures is substantiated. The functions of useful work and time losses are determined; the ration structure of technological processes of basic tillage is proposed. The prospects of using flexible tillage complexes are considered. For each specific case, an algorithm for the ecological and economic assessment of technological and technical solutions is proposed, taking into account the main economic indicators, including energy supply and the quality of the technological processes performed. To reduce energy intensity and improve the environmental situation, a rational structure of recommended levels of technology intensity for the conditions of the Siberian Federal District with an appropriate set of technical support for basic tillage processes is proposed.

Small agricultural enterprises, providing high growth rates of agricultural production, are a significant resource of the state, whose role in the implementation of the food program is growing every year. Recent years have shown an increase in the number of small enterprises engaged in the cultivation of grain crops in the Russian Federation and in the Voronezh region.
 At the same time, many small agricultural enterprises have an insufficient level of production, labor and financial resources, which disrupts the sustainable development of economic entities and the occurrence of bankruptcy of small businesses, the termination of activities. All this requires the search for new approaches and principles for the formation of sustainable development of agricultural enterprises and the definition of their priority areas.
 The article summarizes and analyzes the existing concepts of "sustainability". The economic realities in the field of grain production are considered on the example of small enterprises in the Voronezh region. The risks and threats that contribute to the decline in the development of the grain sector of the economy, represented by small agricultural enterprises in the Voronezh region, are identified.
 The author proposes a system of qualitative and quantitative indicators to assess the level of sustainable development of small agricultural enterprises.
 To obtain conclusions on the stated topic of the publication, the method of comparing and comparing the indicators of small enterprises in the Voronezh region was used. The main principles of sustainable development of small businesses in the agricultural sector are disclosed, the implementation of which in the practice of small agricultural enterprises will contribute to the sustainable development of small businesses, the growth of food security in the Voronezh region and the Russian Federation as a whole.

MODELING OF GRAIN YIELD UNDER HARD-TO-PREDICT CLIMATE

The features of the formation of grain yields in field crop production are presented, climatic indicators are highlighted as the main factors of instability of agricultural production. On the materials of agricultural organizations of the Glazov region and long-term observations of the Glazov meteorological station Udmurtia shows the dependence of crop productivity not only on the purposeful work of a person, but also, to a large extent, on climate conditions during the period of active growth of cultivated crops. Particular attention is paid to the temperature regime and the regime of moisture supply of plants during the growing season from May to August. It has been established that due to the application of mineral fertilizers, grain yields can be increased by an average of 66 kg per kilogram of fertilizers applied.Various regression models are proposed for predictive calculations of future grain harvests, which can also be used for planning when making management decisions. Conclusions were obtained that the ratio of precipitation to average temperatures in the month of June is the most significant of the climatic indicators affecting grain yields. Slightly weaker and with the opposite sign, the influence of the same ratio of climate indicators in May is confirmed. An example of the use of models for agricultural production in the study area is shown. Variants of possible models for a rough assessment of the climatic conditions of future harvests based on the use of neural networks are presented separately, which will justify the plan of agrotechnical measures for the cultivation of grain crops.

Methods of growing high grain yields in Northern Kazakhstan during the years of virgin lands development (the case of the Zarechny state farm)

This article examines the development of virgin and fallow lands in Kazakhstan in the 1950s. Since the climate in the Kazakh steppes was sharply continental, arid, and the soils unsuitable for farming, the cultivation of grain crops was associated with huge risks and difficulties. Everywhere in those years a great number of state farms were established in Kazakhstan, which had to develop not only vast areas in extraordinary conditions and terms, but also apply innovative for that time and for that area methods of cultivation of high yields of grain crops. Analysis of the materials showed that, despite the difficult natural and climatic conditions, lack of agricultural machinery and labour, the virgin lands cultivators harvested high yields by applying the method of layer-by-layer tillage. The authors concluded that in the course of land use state farm specialists tried to maintain the quality characteristics of the soil.

Seasonal Population Dynamics and Harmfulness of Wheat Thrips in Agrocenoses of Grain Crops

The purpose of the study was to identify forage plants and specialized entomophages of wheat thrips in agrocenoses of winter and spring grain crops cultivated in the Samara region. The highest number of adult pests was noted in winter wheat crops (2365.0 ind./100 strokes), the lowest in winter barley crops (565.0 ind./100 strokes). Egg laying by wheat thrip females occurred on all grain crops. Larvae of wheat thrips were noted in the ears of winter and spring wheat, triticale, and winter barley, with the exception of spring barley. During the research, two specialized entomophages were identified: striped thrips and predatory thrips. During the research years, the largest numbers of predatory thrips were noted in winter wheat crops in the earing phase (90 ind./100 strokes) and in spring wheat and spring barley crops in the booting phase—75 ind./100 strokes and 40 ind./100 strokes, respectively. The damage to winter wheat grain by wheat thrips varied from 55.3% to 69.2% and was higher than the damage to spring wheat grain (38.5–64%). With a certain ratio of specialized entomophages and wheat thrips, it is possible to refuse the use of insecticides in the cultivation of grain crops.

The beginning of virgin lands development in Pavlodar region (in 1954)

The article focuses on the initial stage of the virgin and fallow lands development in Pavlodar region. The authors elaborated on the climatic features of the region, noting that this territory was characterized by complex natural and climatic zones and had huge deposits of minerals. The climate in north-eastern Kazakhstan was sharply continental, arid, and the soils were mostly unsuitable for farming, so the cultivation of grain crops was fraught with huge risks and difficulties. The authors conclude that, despite the natural, climatic and other difficulties encountered, the virgin land development activities were completed successfully and in the first years the sown area of grain crops in the Pavlodar region was significantly increased.

Распространение фитопатогенов на зерновых яровых культурах в Уральском регионе

Abstract. In the Ural region over the past decade, the following changes have occurred in agricultural technologies: an increase in the share of stubble backgrounds for the cultivation of grain crops, which entails special phytosanitary risks. Climate change has been expressed in progressive warming over the past 90 years. The purpose of the study was to establish the effectiveness of the fungicidal protection of wheat against a harmful phytopathogen – brown rust – in modern conditions. Methods of All-Russian institute of plant protection were used. Scientific novelty. The modern distribution of phytopathogens on grain crops in the region was assessed and effective preparations were proposed to protect wheat from leaf rust. Results. Moderate and epiphytotic development of leaf phytopathogens on spring wheat took place in 46 % of years. It is during these years that the use of fungicidal plant protection products is mandatory to maintain wheat yields. Biological efficiency of more than 90 % against the local racial composition of brown leaf rust was provided by chemical preparations, variants with combinations of active ingredients propiconazole + tebuconazole and thiophanate-methyl + epoxiconazole were especially distinguished. The use of chemical fungicidal plant protection in the years of epiphytoties retained 32–45 % yield or 7.0–9.4 c/ha. In years with moderate leaf infections, the increase in productivity averaged 3.1–4.8 c/ha. In years with active dry phenomena in the second half of the growing season, the manifestation of leaf rust was single and had no economic significance. The method of immune protection can be actively used, the set of spring wheat varieties with specified parameters for the Ural region is quite wide.

“Direct” sowing of grain crops after potatoes

The effectiveness of the use of “direct” sowing in the cultivation of grain crops in the north-east of the Non-Chernozem zone of the Russian Federation has been revealed. Field experiments were carried out in 2019-2021 on medium loamy low-humus gray forest soils with a high content of mobile phosphorus and exchangeable potassium. The weather conditions during the years of the experiments differed both in terms of heat supply and the amount of precipitation. The objects of the study were: winter wheat of the Moskovskaya 39 variety, spring wheat – Arhat, malting barley – Elf, fodder barley – Pamyaty Rodinoy, corn for silage and grain hybrid NK Gitago. “Direct” sowing was carried out using the Primera DMC (Amazone) sowing complex with the simultaneous application of mineral fertilizers for the maximum planned yield of each crop. On average, the maximum (3.43 t/ha) grain yield when using “direct” sowing was formed when cultivating corn, and the minimum (1.86 t/ha) – malting barley. In the production of these crops, the highest (2.42) and the lowest (1.85) energy efficiency coefficient, respectively, was also revealed. An analysis of economic indicators testified to the expediency of using “direct” sowing in the cultivation of winter wheat, which was reflected in obtaining the maximum (73.3%) level of profitability. The minimum (31.5%) level of profitability was noted in the cultivation of malting barley, which is explained by the high degree of material and labor costs and its relatively low yield. The profitability of the production of other types of crop products was 1.18-1.94 times lower. In general, the agronomic, energy and economic assessment showed bright prospects for the cultivation of winter wheat and maize for grain using the “direct” seeding method after potatoes.

Modernization of the granular materials dryer

BACKGROUND: The solving of priority tasks for the development of the agro-industrial complex considers the creation of advanced scientific developments. Innovative research of technical means and technologies of mechanization of agricultural production is not an exception in this regard. In the agricultural sector of Russia, crop production occupies a key place, in which the cultivation of grain crops is a priority. In the whole range of operations in the production of grain, the most important part of it is post-harvest processing of grain. One of the main stages in the post-harvest processing of grain is drying, in which the raw materials are brought to the moisture regain (down to 14%). Proper preparation of grain for storage ensures its reliable safety.
 AIMS: Modernization of the granular materials dryer by means of new technical solution at the level of patentability.
 METHODS: Research of the state of the issue on the topic under consideration with the help of a review of literary sources. Patent search for technical devices of grain dryers. Studying the principle of their functioning and design features. Analysis and generalization of the material for the adoption of a new design solution.
 RESULTS: The use of innovative technologies with the new generation harvesters, characterized by high productivity, has significantly reduced the duration of harvesting, and this, in turn, has significantly aroused the interest in drying. The use of dryers with improved quality indicators of functioning significantly reduces the time for preparing raw materials for long-term storage, reduces grain losses in the field during harvesting, and, in addition, makes it possible to carry out the process of transferring grain from the field to a special long-term storage warehouse in the shortest possible time and with the least losses. There are various ways of drying granular materials. These are main methods based on increasing the temperature of the processed material. Drying of grain with the help of heated air has become the most widespread.
 CONCLUSIONS: As a result of the conducted research, the drawbacks of existing technical devices for granular materials drying, as well as the principles of their functioning, have been revealed. A detailed analysis of literary sources, including a patent search, made it possible to upgrade the processed raw materials dryer, characterized by a simple and reliable design.
