The purpose of the research was to establish the most rational soil cultivation system for irrigated conditions, contributing to the preservation of ecological balance and increasing the profitability of pepper production. Experimental studies were carried out on meadow-chestnut soils of the plain zone of the Republic of Dagestan in 2017-2019. in a two-factor experiment to determine the most effective combination of soil cultivation and irrigation regime. The paper presents the results of the influence of plowing and disc cultivation on the water-physical properties of the soil and its biological activity, as well as on the yield of sweet pepper under drip irrigation. The results of three-year research have established that, under irrigation conditions, the most effective method of basic soil cultivation is moldboard soil cultivation to a depth of 0.23 ... 0.25 m, which contributed to the improvement of soil density, its permeability, structural state and increased biological activity in the treated layer. On plowing, the yield of sweet pepper fruits was obtained at the level of 6.23 t/ha. The use of disc processing by 0.10 ... 0.12 m leads to a deterioration of agrophysical indicators of fertility, phytosanitary state of irrigated fields by 1.7 ... 2.2 times, a decrease in yield by 5.1 ... 9.6% and profitability of pepper fruit production by 25.3 ... 31.0%.

Abstract The advantages of drip irrigation of many agricultural crops are well known, but it does not allow to regulate the phytoclimate in the “environment-plant” system, which is especially important for the conditions of the hot and dry climate of the Republic of Dagestan. Currently, the efficiency of fine sprinkling on the background of drip irrigation was insufficiently studied, as questions remain the combined effect of irrigation on crop productivity in real climatic conditions on the effectiveness of combination with other agronomic techniques, etc. Experimental studies were conducted on the experimental field of the Department of Agriculture, Soil Science and Land Reclamation in the educational and experimental farm of the Dagestan State Agrarian University. The main purpose of the research was to determine the parameters of the combined irrigation technology, its effect on the microclimate of the irrigated field and the phytoclimate of plants, as well as the productivity of sweet pepper. As the result of experimental studies, it was found that the use of a combined irrigation system (drip irrigation + fine sprinkling) when cultivating sweet pepper allows to obtain an additional 9.4 t/ha of marketable products by optimizing the growing conditions.

During the ripening of sweet pepper (Capsicum annuum L.) fruits, in a genetically controlled scenario, enormous metabolic changes occur that affect the physiology of most cell compartments. Peroxisomal catalase gene expression decreases after pepper fruit ripening, while the enzyme is also susceptible to undergo post-translational modifications (nitration, S-nitrosation, and oxidation) promoted by reactive oxygen and nitrogen species (ROS/RNS). Unlike most plant catalases, the pepper fruit enzyme acts as a homodimer, with an atypical native molecular mass of 125 to 135 kDa and an isoelectric point of 7.4, which is higher than that of most plant catalases. These data suggest that ROS/RNS could be essential to modulate the role of catalase in maintaining basic cellular peroxisomal functions during pepper fruit ripening when nitro-oxidative stress occurs. Using catalase from bovine liver as a model and biotin-switch labeling, in-gel trypsin digestion, and nanoliquid chromatography coupled with mass spectrometry, it was found that Cys377 from the bovine enzyme could potentially undergo S-nitrosation. To our knowledge, this is the first report of a cysteine residue from catalase that can be post-translationally modified by S-nitrosation, which makes it especially important to find the target points where the enzyme can be modulated under either physiological or adverse conditions.

Abstract Ripening is a complex physiological process that involves changes in reactive nitrogen and oxygen species that govern the shelf-life and quality of fruits. Nitric oxide (NO)-dependent changes in the sweet pepper fruit transcriptome were determined by treating fruits at the initial breaking point stage with NO gas. Fruits were also harvested at the immature (green) and ripe (red) stages. Fruit ripening in the absence of NO resulted in changes in the abundance of 8805 transcripts whose function could be identified. Among these, functional clusters associated with reactive oxygen/nitrogen species and lipid metabolism were significantly modified. NO treatment resulted in the differential expression of 498 genes framed within these functional categories. Biochemical analysis revealed that NO treatment resulted in changes in fatty acid profiling, glutathione and proline contents, and the extent of lipid peroxidation, as well as increases in the activity of ascorbate peroxidase and lipoxygenase. These data provide supporting evidence for the crucial role of NO in the ripening of pepper fruit.

Livestock products are the most important component of the actual total volume of farm produce. A reliable fodder base is required to increase their quantity and quality. The most part of the natural forage lands of the Republic of Kazakhstan is located in areas with insufficient water availability and low soil productivity. When they are used intensively, they are thinned and degraded. Their restoration and improving is possible if effective technologies and technical means are effected. However, the existing methods for improving and restoring forage lands and the technical means for their implementation are not adapted to the natural­climatic and agrobiological features of the zone of Central and Northern Kazakhstan, which feature insufficient moisture supply and low productivity.The main indicator of the effectiveness of the use of fodder crop seeds is their uniform distribution in the soil. However, most of them, due to their poor flowability, form dome structures of different sizes in front of seeding openings, which hinder the seeding process. To increase the flowability of such seeds, they are mixed with sand, sawdust, fertilizer and other materials. However, during the operation of seeders, the mixture is stratified according to its specific gravity. (The research purpose) is to develop a lobe­type agitator, which prevents the formation of a dome over seed holes. (Materials and methods) Theoretical studies have been carried out using the methods of classical and applied mechanics, as well as special sections of higher mathematics. (Results and discussion) The authors have experimentally confirmed the main parameters of the agitator and its resistance to movement in a seed medium. Experimental studies have been carried out on the basis of GOST 31345­2007. The studies have confirmed that a four­lobe agitator with an external radius of 0.06 m and an inclination angle to the plane of rotation 20°, mounted on the fertilizer drill SZS­2.0, has shown a total resistance of 3,042 kg with a design value of 2.925 kg. (Conclusions) The obtained results can be offered to the designers and developers of machines of the considered type when calculating and designing their working elements.

Knowledge on status of peripheral plant populations is important for understanding of species’ adaptation and evolution within their ranges.  There is a lack of data on the status of Silaum silaus (Apiaceae) populations at the periphery of its native range.  One of the most northern native S. silaus populations is situated in the Republic of Mordovia (Central Russia).  This species is considered as Critically Endangered in the region.  Population-based studies of S. silaus have been carried out. Reproductive biology, morphometric parameters of individuals, accompanying flora, seed characteristics (mass, germination rate) were investigated.  Results showed that at the northern limit of the range S. silaus grows in floodplain meadow community previously disturbed by livestock grazing. The area occupied by the population, however, has increased more than 12 fold over the last 15 years. Increasing fruit production together with decreasing fruit mass was established for the studied population compared to populations in the central part of its native range.  In addition, germination rate was very low (2.3–16.7 % depending on edaphic conditions).  Additional studies of S. silaus populations are needed in saline steppes of the closely located territories where it occurs as one of the dominant species in the plant community.

Benzoquinone and its reduced form hydroquinone belong to phenolic compounds and are found in living organisms in free form or in glycosides. They are active substances of some medicinal plants and have a pharmacological effect on the human body. Accordingly, their derivatives are important objects for chemical synthesis and development of new drugs. This article presents the findings of the structural design of substances with benzoquinone or hydroquinone fragment and sulfur-containing compound. By use of appropriate on-line programs a predictive screening of the biological activity and cytotoxicity of thiosulfonate derivatives of benzoquinone and hydroquinone has been conducted. It has been found that they have immense methodological potential to be synthesized by substances with a wide range of biological activities and a high value of probable activity, which substantiates the feasibility of conducting experimental studies on their biological activity, particularly anticancer.

Apart from causing serious yield losses, various kinds of mycotoxins may be accumulated in plant tissues infected by Fusarium strains. Fusarium mycotoxin contamination is one of the most important concerns in the food safety field nowadays. However, limited information on the causal agents, etiology, and mycotoxin production of this disease is available on pepper in China. This research was conducted to identify the Fusarium species causing pepper fruit rot and analyze their toxigenic potential in China. Forty-two Fusarium strains obtained from diseased pepper from six provinces were identified as F. equiseti (27 strains), F. solani (10 strains), F. fujikuroi (five strains). This is the first report of F. equiseti, F. solani and F. fujikuroi associated with pepper fruit rot in China, which revealed that the population structure of Fusarium species in this study was quite different from those surveyed in other countries, such as Canada and Belgium. The mycotoxin production capabilities were assessed using a well-established liquid chromatography mass spectrometry method. Out of the thirty-six target mycotoxins, fumonisins B1 and B2, fusaric acid, beauvericin, moniliformin, and nivalenol were detected in pepper tissues. Furthermore, some mycotoxins were found in non-colonized parts of sweet pepper fruit, implying migration from colonized to non-colonized parts of pepper tissues, which implied the risk of mycotoxin contamination in non-infected parts of food products.
