Mathematical description of the drying process of mulberry leaves
Authors: Verma Sunil , Usenov A B , Sobirova D U , Sultonova S A , Safarov J E
Published: December 2022

Three mathematical models were used in this study: the Newton model, the Henderson-Pabis model, and the Page model. Three models were chosen for comparison with experimental data because they are commonly used to describe the drying characteristics of thin films and are simplifications of the theoretical model derived from the diffusion equation (Fick’s second law). The Newton model is a mathematical model for drying a thin layer, also called the Lewis model. Lewis described that the transfer of water from food and foodstuffs can be shown by analogy with the outflow of heat from the body when the body is immersed in a cold liquid. The Henderson-Pabis model has been used in thin-layer drying of various agricultural products, including drying of corn, wheat, coarse rice, beans and tubers. The Page model is a modified model of the Lewis model. Page proposed this model to correct the shortcomings of the Lewis model. Page’s model has created models that are suitable for describing the drying of various agricultural products and are easier to use than other equations.

Published: December 2022

The results of researches implemented in the sphere of improving the agrotechnical passability of 4-wheeled universal-row cotton crop tractor are specified in the article. Replacing these two types of wheeled tractors with one high-clearance 4-wheeled tractor significantly reduces the range of fleet and increases the annual load of universal-row crop tractor of 1.4 class, and finally, increases the efficiency of their applying. The weight distribution of perspective four-wheeled universal-row crop tractor onto four wheels and fully drive reduces the negative impact on soil in comparison with three-wheeled tractor and allows to aggregate machines having enlargedrow-spacings. Evaluation of P indicator (the passability margin) is shown. It characterizes the passability through more problematic matters due to traction-coupling properties presowing soil processing proceedings, which showed the possibility of applying the tractor as well at all remaining operations, provided for by the technological map and being performed by the units on the base of this tractor.
Combined processing of metal surfaces in agriculture with concentrated energy flows
Authors: Kapitonov Mikhail V
Published: December 2022

Modern agritech technologies are complexes of technological operations for managing the production processes of agricultural crops in agrocenoses in order to achieve the planned yield and product quality while ensuring environmental safety and certain economic efficiency. An analysis of the development of agroengineering technologies for the impact of concentrated and highly concentrated energy flows on the surface of materials shows that progress in the use of flame, induction, laser, plasma and other types of energy flows has reached its limit. The technological impasse in agriculture well illustrates the axiom that it is impossible to create universal methods and tools capable of providing exponential development over significant periods of time. Quantitative and qualitative limitations in the use of each individual technology in agriculture stimulate the search for new agricultural solutions. A multiple increase in productivity, the acquisition of competitive advantages, a significant improvement in the quality of the treated surface and obtaining unique, in many respects, properties of materials in agriculture can be achieved due to the synergistic effect when using hybrid technologies. Their efficiency is ensured by saving processing time without loss of quality. The reduction of time costs occurs due to a significant reduction in the number of auxiliary operations or their complete elimination.

Authors: Rozhkova-Timina I O , Reshetnikova E D
Published: December 2022

Nowadays due of the world population growth, the demand for agricultural products is also growing. To obtain good meat and dairy products, high-quality feed for farm animals is necessary. Legume-gramineous perennial grass mixtures are used to improve fodder lands. Our experience included a test of 9 variants of legume-gramineous grass mixtures, where 6 types of grasses were used: red clover, alfalfa (legumes), meadow timothy grass, orchard-grass, smooth brome-grass, meadow fescue (cereals). The experiments were carried out in four repetitions on the lands of hay and pasture use with the use of fertilizers; there were carried out phenological observations, biometric measurements, and determination of the botanical composition. In herbage from hay fields the smooth brome-grass dominated, and in herbage from pastures the orchard-grass dominated. The proportion of non-sown grass species reaches 26.3-32.7 % in three-component grass mixtures with meadow timothy grass. Meadow fescue and meadow timothy in terms of growth rate, reactions to nitrogen application were inferior to the orchard-grass and smooth bromegrass, which led to their oppression and displacement from the herbage. The best density of plant standing per 1 m2 was noted in the orchard-grass and smooth bromegrass, the smallest - in meadow fescue and alfalfa.

The main and economically priority vector of development of agroindustrial complex of the Russian Federation in the current realities is sustainable production of agricultural products in volumes that not only meet the needs of the population, but also create a certain reserve, able to offset the negative effects of forced production downturns and crises. Beef is a high-quality source of protein in human nutrition. In the conditions of protein diet deficiency the question of increasing the volumes of animal production and, in particular, beef as one of the main traditional components of human diet acquires the special urgency. In this connection, we have set the task to study the indicators of beef productivity of Limousin cattle under the conditions of stabling system in a farm located in the biogeochemical conditions of Voronezh region of the Russian Federation. The researches made show that the meat productivity of cattle of Limousin breed differs significantly in pre-slaughter weight of bulls and heifers amounted 621.33 kg and 449.67 kg, and the slaughter weight of steers and heifers was 385.37 kg and 272.30 kg. The slaughter yield of steers was quite high and was 61.98±1.06%, while that of heifers was slightly lower and was 59.90±0.58%. The most interesting is the comparative evaluation of meat quality in interbreed and age aspects according to its dry matter and water content, protein and fat content, as well as other indicators characterizing the product quality, so the ratio between protein and fat in meat, the water-holding capacity of meat proteins were studied to determine the manufacturability and meat quality. Also, indicators characterizing the chemical composition of the longest muscle of the back were determined.

Authors: Ozerova M G , Fedorova M A
Published: December 2022

Sustainable development of food systems is a global challenge for both Russian and world economy. Within each country, the economic, social and environmental aspects of sustainability should be considered in symbiosis when forming conditions for the development of agricultural sectors. Dairy cattle breeding has always been one of the leading sub-sectors of agriculture, the prerogative of which is to provide the population with milk and dairy products in an amount that advises recommended consumption standards. Digital transformation of the sub-sector is considered as an element of the global project in the Ministry of Agriculture of Russia “Digital Agriculture”. The paper presents analytical materials on the level of self-sufficiency and economic availability of milk and dairy products in Russia as a whole, as well as the current state of the production potential of dairy cattle breeding in the Krasnoyarsk region. It was found that the loss of gross milk production due to a decrease in the number of cows compensates for the increase in productivity. It is noted that in Russia the agricultural industries are going through the next stage of serious technological changes, which is associated with the need to modernize production based on the use of information technologies, automation capabilities, digital technologies and platform solutions. This process helps to solve the main task – to ensure the sustainable development of food systems on the basis of increasing the production potential of industries.

Authors: Kovalev I V , Kovalev D I , Shaporova Z E , Voroshilova A A , Borovinskii D V
Published: December 2022

The article presents an example of a statistical analysis of agro-climatic factors of crop failure in agricultural plots for the cultivation of rice. It is shown that crop failure is mainly due to a variety of random, independent agro-climatic factors: the sum of active temperatures, the sum of precipitation, soil fertility, etc. Agricultural technology of crop cultivation also has a significant impact on crop failure, which is characterized by the following features: the predecessor, the amount of fertilizer, weeding, the number of days from the bay to the discharge of water, the number of days from mowing to threshing. As methods of statistical data processing, the authors use complex data processing by traditional methods, including comparison of mean values of features, principal component analysis, multiple regression analysis, and discriminant analysis. It is noted that the results of complex processing of the agrotechnical characteristics of plots with different rice yields using the apparatus of one-dimensional and multivariate statistical analysis provide a basis only for identifying general trends, since the agrotechnical system has a high level of complexity. For a deeper and more complete penetration into its essence, an apparatus should be used that can identify and take into account the structural heterogeneity of data about this system.

Authors: Khuat Q V , Kalashnikova E A , Nguyen H T , Slovareva O Y , Kirakosyan R N
Published: December 2022

Fusarium oxysporum fungus is the pathogen that causes wilts or root and crown rots on many economically important field crops, causing significant losses to agricultural production. The use of plant extracts to control this fungus is an alternative to synthetic fungicides. Black cardamom (Amomum tsao-ko Crevost et Lemairé), which belongs to the monophyletic Zingiberaceae family, is a valuable medicinal plant in Vietnam. The antifungal activity of black cardamom seed extract has been reported in several previous studies. This study aimed to determine the antifungal activity of black cardamom extracts against the F. oxysporum fungus. The fungicidal effects of black cardamom extracts (including ethanol extract of leaf, seed, rhizome + root, and pseudo-stem) concentrations of 50 and 100 mg/L were investigated. Results indicated that the black cardamom extracts had different fungicidal effects on the growth of F. oxysporum mycelium. A significant inhibitory effect on the growth of F. oxysporum mycelium was obtained using the seed extract at a concentration of 100 mg/L. In addition, in the variant with the use of the extract obtained from the seeds, the lowest indicator of the specific growth rate (m) of the fungus was observed. The antifungal components from black cardamom plant could be used in developing novel fungicides (biopesticides) for the diseases caused by F. oxysporum.

Authors: Borzenko S V , Usmanov M T
Published: December 2022

It was shown that with increasing salinity of waters, it was determined that concentrations of dissolved heavy HREEs and medium MREEs increase in soda lakes. It was determined that sulfatreduction and secondary mineral formation can influence the migration of lanthanides in lakes. Sulfatreduction leads to accumulation of lanthanides of medium MREEs and heavy HREEs subgroups in lake waters. The content of lanthanides of the light LREE subgroup is controlled mainly by secondary mineral formation. Thermodynamic calculations show that the degree of saturation in parasite CaCe0.95La0.6Nd0.35Pr0.1(CO3)3F2 and bastnesite CeCO3(OH)F is higher in soda lakes than in chloride lakes. The saturation of lake waters with respect to cerium hydroxide III in anaerobic and cerium hydroxide IV in aerobic conditions leads to the formation of negative cerium anomaly in lake waters of the considered lake types. It is shown that the different nature of the formation of soda and chloride lakes is the main reason for different concentrations of REEs in their waters and bottom sediments.

Published: December 2022

This article describes that at the moment the level of the Aral Sea and the volume of water has decreased rapidly. The desiccation of the sea affected the entire region of its former water area as a whole: ports were closed, fishing in industrial volumes stopped, since the salinity of the water increased almost 10 times, and many species of flora and fauna could not survive in dramatically changed conditions. The climate of the Aral Sea has also changed – winter has become colder and longer, and summer has become even drier and hotter. Salinization of unsalted arable lands and further salinization of saline soils increases every year due to wind dust and salt from the Aral Sea and other saline soils. To maintain the fertility of irrigated saline soils, their salinization is washed annually (mainly in autumn and winter). To do this, the lands are inspected and washed away. During the washing process, part of the water is absorbed into the ground and carries away part of the salt. Most of the water leaves the cultivated fields and returns to drainage channels, from which to water supply channels for irrigation of crops, and then to rivers. The distribution of the rate and concentration of salt and sand deposition depends on the height and time above the level, it was determined that a number of positive works were carried out to improve the condition of the soil, its rational use and increase soil fertility, as well as to maintain the fertility of irrigated saline soils, their washing.

Agricultural land plot reclamation of citrogypsum sediment pool on Belgorod city territory
Authors: Melentyev A A
Published: December 2022

One of the main society tasks with the rapid development of industry is assigned to nature protection and correct use of natural resources. Therefore, a significant role is put to the hands of land use. Today, the mining industry in the Russian Federation is characterized by huge volumes of mining. The main production is carried out mainly due to the open method of work. The negative consequences of such developments are: taking of large land areas from the economic turnover, their violation in the course of work; changes in hydrogeology and landscapes; development of erosion processes, etc. Thus, as a result of mining operations, the areas of land disturbed by such developments, processing waste and mucks of rocks are rapidly increasing. Moreover, when mucks are formed, unnecessary rocks are mucked, without taking into account their suitability for reclamation, and when creating external mucks, the requirements of rational farming are not always taken into account. As a result, these lands become barren and negatively affect the environment. It follows from this that lands disturbed by open pit mining must be returned to economic circulation with minimal losses and the creation of favorable conditions for the environment. The work relevance lies in the study of work on the land restoration in quarries during their development and extraction of raw materials for construction purposes. Reclamation provides for the restoration of lands disturbed by quarrying, as well as the preservation of the already restored land.

Published: December 2022

Forest fires are one of the problems that impede the conservation and rational use of national resources, as well as restraining the development and sustainable environmental safety of the forest industry. Damage from forest fires is expressed not only in damage to trees, but also in the destruction of the animal and plant world. In addition, the number of forest fires arising directly near settlements is increasing, which leads to the destruction of residential buildings by the elements, as well as the death of people and pets. Such serious negative consequences predetermine the need to develop urgent ways to improve the activities of law enforcement agencies that ensure the protection and protection of natural resources of the Russian Federation. The purpose of this study is to study the activities of the internal affairs bodies to prevent forest fires and eliminate their consequences. As a result of the study, the author analyzed the dynamics of various indicators and individual measures that reflect the effectiveness of the activities of the internal affairs bodies to prevent forest fires. The author’s principle of forest insurance is practical. The use of the proposed tool will increase the efficiency of government agencies in the process of ensuring environmental safety and eliminating the consequences of forest fires.

Cecum microbes are important in utilizing feed nutrients and immunity systems in poultry. This study strived to define the composition of the genus Collinsella, Coriobacteriaceae UCG-002, and Olsenella in the quail cecum supplemented with different betaine schemes. The treatment consisted of 3 levels, namely: control (C); C+0.12% betaine supplementation (B1); and B1–0.12% betaine supplementation (B2). This study used a completely randomized design with three replications. The next-generation sequencing method of the 16S rRNA gene region V3-V4 was applied to view the taxonomy profile of microbes (Threshold: 0.8~1). The relative abundance of the genera Collinsella, Coriobacteriaceae UCG-002, and Olsenella were analyzed using ANOVA and Duncan’s test on R software. The results showed that the provision of B1 increased genus Collinsella and Coriobacteriaceae UCG-002 more than C and B2 (p<0.05). A significant decrease occurred in treatment B1 compared to treatment C indicated in the genus Olsenella as a pathogenic bacterium in the quail cecum (p<0.05). The B2 treatment showed the relative abundance of the genera Collinsella, Coriobacteriaceae UCG-002, and Olsenella tended to return to the microbial composition of treatment C. This study concluded that giving B1 improved the genus Collinsella, Coriobacteriaceae UCG-002, and Olsenella in the quail cecum tract.

Decreased productive performance due to heat stress in poultry often occurs in tropical environments. This study seeks to see the body temperature and productive performance of quail in different floor spaces and levels of betaine supplementation. The study was designed as a completely randomized design, consisting of two floor spaces (225 and 164 cm2/bird) and supplementation treatment (0% and 0.15% betaine). ANOVA test and DMRT were applied to catch the effect of treatments. Body temperature measurements showed that rectal and wing temperatures in quail with betaine supplementation were lower than in the control treatment (P<0.05). These results correspond with the betaine group’s feed, protein, and energy efficiency, which is better than the control (P<0.05). The egg production at floor spaces 225 cm2 and 164 cm2 supplemented with betaine was higher than the control groups (P<0.05), with values of 69.55% and 66.49%, respectively. Based on this study, we concluded that betaine supplementation to 225 cm2/bird and 164 cm2/bird floor spaces reduced heat stress and improved laying quail performance.

Currently, the Black Soldier Fly (BSF) insect is a prima donna among farmers, especially poultry because it has high protein and easy breeding in waste media. BSF in each phase will have a different nutritional content and exoskeleton, in the prepupa phase it has a high protein content and a slightly hard exoskeleton indicating the presence of chitin and chitosan components. To get chitin and chitosan extraction process is carried out, the process also has differences in producing chitin including demineralization and deproteination stages while producing chitosan includes demineralization, deproteination, depigmentation and deacetylation stages. This study aims to extraction of chitin and chitosan BSF prepupa phase on characterization and yield. The results of this study showed that the extraction chitin of BSF prepupa phase resulted in a yield of 18.05% and the characterization was blackish brown, while the extraction chitosan of BSF prepupa phase resulted in a yield of 10.85% and the characterization was white (pure).

This study explores the value chain mapping of porang (Amorphophallus muelleri) in Wonogori Regency to describe the flow of porang products, information, and finances from upstream to downstream chains. In addition, this study also explains the role of each actor in the chains in increasing the added value of porang tubers. A survey was conducted in Wonogiri Regency by interviewing various actors involved in porang value chains. To select the respondent, we used snowball sampling. Secondary data are also used from food security offices and central agency of the statistics of Wonogiri regency. A total of 45 respondents were interviewed out of the total pool of actors, which included farmers, rural traders, subdistrict traders and wholesalers. Descriptive analysis was used to describe the porang value chain in Wonogiri Regency. The survey results show that there are four routes of value chain mapping. The actors from the upstream to the downstream chain coordinate to supply the porang to processors. Each actor in the chains plays a different role in increasing the added value of the porang. Farmers focus on production, while intermediate actors focus on purchasing and distribution; processors are concerned about processing the porang.

Non-wood forest products (NWFPs) are part of forest ecosystem and it has certain functions that support ecosystem sustainability. Utilization of NWFPs is a sustainable use or utilization of by-products from trees or other forest products. The present study aimed to obtain basic information on the NWFPs species that cultivated in Gempolan Village. Therefore, the species density, relative density, frequency, relative frequency, and important value index was calculated. In addition, the utilization of NWFPs species was described based on the interview. Field observation was conducted in 38 community forest by making plots 40 × 25 m2. Furthermore, interview was conducted with the owner of those community forests to obtain information on the NWFPs utilization. The results showed that community forest management in Gempolan Village applies an agroforestry system with a random mixture and alternate row-cropping pattern. NWFPs can be classified as their function, namely as food, medicinal plant, animal feed, and spices/condiments. Most of the NWFPs were only used to meet their own needs. NWFPs that produces from community forest in Gempolan Village was dominated by multi-purposes tree species (fruits) such as durian, avocado, jengkol, petai, pakel, sawo, melinjo, jackfruit, and breadfruit.

Environmental policy practices in various countries and governments certainly differ, as one country may prioritize it, while others do not. Several factors including economic welfare, the human development index, and even the awareness of sustainable development may contribute to the variation. Comparing government performance in utilizing technological development and the internet is significant to assess the government’s performance in ensuring environmental sustainability and the establishment of smart governance at the same time. This paper discusses how the websites of local governments can be used to socialize and apply the environmental policy in Surakarta, Indonesia, and Pingtung, Taiwan. The two cities are chosen because of their contrasting condition where the prior has a limited but growing awareness of environmental policy, and the latter has already established systematic environmental policy planning and application. This research focuses on the observational analysis of the websites and will be supported by a literature study that is available on the Internet using search engines. The projected results showed the difference between both cities in actuating their environmental policies through websites and the factors that may cause it. Further findings can be found in the article.

Transportation causes sheep to experience stress and body weight loss due to physical stress during the process. This study aimed to evaluate the administration of protected methionine hydroxy analog (MHA) or dextrose before transportation on body weight loss, physiological responses, and post-transportation behaviours of sheep. The study used 42 thin-tailed sheep (body weight 18.28±2.11 kg) that were divided into three treatments, i.e., without MHA/dextrose supplementation (P1, control), supplementation of MHA 0.24 g/kg body weight (P2), and supplementation of dextrose 0.24 g/kg body weight (P3). Sheep were transported for a 6-hour journey in commercial vehicles. The results showed that P2 and P3 significantly reduced (P<0.05) the length of time for the sheep to reach their initial body weight before transportation. The P2 and P3 significantly decreased (P<0.05) pulse and respiratory rates as compared to P1. The resting behaviour of P1 was significantly higher (P<0.05) than P2 and P3, while the standing behaviour of P2 and P3 was significantly higher (P<0.05) than P1, which indicated an improvement of sheep condition in the P2 and P3. It can be concluded that the supplementation of MHA or dextrose before transportation improves the bodyweight recovery time, physiological conditions, and behaviours of sheep under transportation stress.
