Abstract
The species composition of phytopathogenic fungi isolated from seeds of lawn grasses (pasture ryegrass, shoot grass birch and meadow bluegrass) was revealed and the dominant genera and species were identified. The main components of the pathogenic mycobiota of seeds were fungi: Fusarium – 44 %, Alternaria sp. – 37 %, Penicillium sp. – 12 %, Mycelia sterilia – 5 %, Cladosporium sp. – 2 %. In laboratory conditions, the biological effectiveness of the preparations was evaluated: Strekar, VRK (d.v. phytobacteriomycin + carbendazim), Fitolavin, VRK (d.v. complex of streptotricin antibiotics + phytobacteriomycin), TMTD-plus, KS (d. tiram + immunomodulators), Celest Top, KS (AI thiamethoxam + fludioxonil + diphenoconazole), of which Strekar, VRK, maximally increased the length of ryegrass seedlings, however, the length of the coleoptile was higher in the variant with TMTD-plus, KS, and the best effect on bluegrass seeds was provided by Celest Top, KS and TMTD-plus, KS. The contamination of seeds was reduced after treating with TMTD-plus.

Published: January 2021

Abstract
The article contains an introduction, general research objectives are indicated, a comprehensive solution for evaluating raw materials for industrial processing for various types of food products is presented, 18 promising table grape varieties are studied as well as their yield and commercial quality, the percentage of non-standard products is determined, and mathematical processing of data is carried out. Correlation and regression analysis showed that the relationship between yield and yield of marketable grapes is reliable and strong, and the form of correlation is direct (r = 0.99). The indicated dependence is described by the equation y = 0.937x–1.2139. The regression coefficient by x = 0.937 shows in which direction and how the function (y) changes on average when the argument (x) changes. Using the obtained equations, it is possible to construct a theoretical line of regression, according to which it is possible to predict the value of marketable grapes from yield. An increase in the yield of grapes for every 10 centners per hectare leads to an increase in the yield of marketable grapes by 9.37 %.

In recent years, the demand for forest food and medicine products has increased, as it is a source of vitamins, minerals and biologically active substances. In addition, they are more environmentally favorable food products and are not processed with chemicals during the growth period. High nutritional value or useful medicinal properties are reduced to zero when the level of toxic substances in them exceeds the maximum permissible norms. Research on the ecological purity of wild plants is an urgent issue. The object of the study is wild-growing berries growing in the Vologda Region. The study used generally accepted methods in assessing the food safety of food products. As a result, it was established that the Vologda Region has a significant resource potential of wild berries. Procurement can be carried out on an area of 110510 thousand km2, and the estimated annual amount of resource withdrawal may be 40591.1 tons. The quality of berry raw material exceeds established standards. When assessing environmental cleanliness, it was found that wild forest berries of the Vologda Region contain less cesium-137 and nitrates than the maximum permissible levels of hazardous concentrations. This fact indicates the possibility of using berries in food production, including baby food.

Abstract
The article presents the results of evaluation of rice varieties grown in the conditions of Krasnodar region by technological and biochemical quality traits in connection with the degree of grain polishing. The experiments were carried out in the laboratory of grain quality of Federal Scientific Rice Centre, Krasnodar. Grain of four rice varieties of Russian breeding (Rapan, Flagman, Polevik and Olimp) was subjected to five different degrees of polishing (0 %, 10 %, 12 % and 14 %). The degree of polishing significantly (P≤0.05) influenced the total yield of polished rice, head rice content, and the content of protein and amylose. An increase in the degree of polishing led to a further decrease in the protein content, total yield of polished rice and head rice content in it. However, an increase in the amylose content was found for simulated samples. With an increase in the degree of polishing to 14%, the amylose content increased in varieties Rapan, Flagman, Polevik and Olimp, respectively, by 1.3 %, 1.4 %, 1.5 % and 1.2 %, the protein content decreased by 1.5 %, 1.7 %, 1.6 %, 1.7 %.

Published: January 2021

AbstractThe effectiveness of agricultural production in dairy farming and the degree of its intensity are directly related to the organizational and economic mechanism of reproduction and the appropriate use of the material and technical base of agriculture. For agricultural producers, the material and technical security, as well as the methods of reproducing the material and technical base in current economic conditions, directly depend on the financial situation, the size of the enterprise, and many other factors affecting the availability of borrowed funds and state support funds. The article discusses the state of technical equipment of dairy cattle breeding, the impact of new, modern, innovative equipment on the efficiency of production. The estimation of technical support of the dairy industry in agricultural enterprises of Russia and the Omsk region is given. The methodological basis of the study was the provisions of modern concepts of analysis of agricultural economics, formalized and intuitive methods for modelling the economic development of the dairy industry. The assessment showed that the technical equipment of dairy farming and its supporting engineering base are at a relatively low level. The solution to these problems is not possible without attracting investment resources for technological and technical re-equipment of the industry.
The environmental-biology aspects of use of chitosan and ultrafine particles of copper and iron in the nutrition of broiler chickens
Authors: Ivanishcheva A P , Sizova E A 
Published: January 2021

Abstract
The natural biopolymer chitosan is currently of great interest to specialists in the field of medicine and veterinary medicine due to properties such as biocompatibility, good sorption and low allergenicity. The aim of the study is to study the environmental-biology effect of chitosan and UFP on growth, productivity and morpho-biochemical blood parameters of broiler chickens. The study was performed on broiler chickens of «ArborAcres» cross (n = 60) in the conditions of vivarium. Biochemical studies of blood serum were performed using an automated analyzer CS-T240 (DIRUI Industrial Co., Ltd, China). The use of chitosan (group I) and UFP (group II) leads to a positive productive effect, however, the joint feeding with chitosan with UFP (group III) does not give a similar result. Feeding with chitosan-containing diet (group I) reduced the concentration of total cholesterol and triglycerides to a greater extent than the use of UFP (group II). Against the background of the introduction of chitosan into food (group I), the activity of catalase increased compared with that of the control. The level of malondialdehyde (MDA), as an indicator of lipid peroxidation, decreased with all variants of feed additives. The use of chitosan and UFP in the diets of broiler chickens is advisable and helps to normalize the metabolism and productivity of the bird. The results indicate a promising approach, and requires further research as a component that can be used in the industrial production of animal feed.

Published: January 2021

Abstract
Currently, the problem of the ecological purity of food products is becoming urgent. Food safety assessment includes monitoring the content of toxic elements, while carrying out the necessary analysis for the presence of aluminum, lead, cadmium, tin and strontium using the method of atomic emission spectrometry and mass spectrometry. A relatively new and safe method of detoxification is the use of probiotic strains with the ability to bind heavy metals. The purpose of our study is to form control of the quality of food raw materials by determining the level of toxic elements in poultry products to assess the safety of the product, with the additional inclusion of a probiotic preparation. Based on the studies carried out, a method has been developed for determining low concentrations of toxic elements in food raw materials, which will allow one to further strengthen control of the quality and safety of food and reduce the incidence of diseases caused by alimentary factors.

Abstract
The Republic of Azerbaijan has all the conditions, both natural and socio-economic, for the development of horticulture. Over the last decade, the gross harvest of vegetables has been growing steadily. By 2018, it was 1522 thousand tons. The yield of vegetables has also grown in the indicated period from 14.7 to 21.9 t/ha. Vegetables occupy 4800 ha of a protected ground. The production of greenhouse vegetables targets the Russian market. The bottleneck of this sector is the breeding of vegetable seeds. This market, with a capacity of almost 20 million Euro, is occupied by foreign companies. At the same time, agricultural producers get help from the state in the form of subsidies, preferential credits, and full tax exemption. The research in the sector is also developing. We can note such possible developments as the renovation and outfitting of the Research Institute for Horticulture as well as the training of horticulturists in the Azerbaijan State Agricultural University. The further development of the sector continues in the way of the intensification and biologization of production, the improvement of the range and quality of products.

Published: January 2021

Abstract
In this study, the elemental composition of the hair of Holstein cows (n=50) from two different regions of Russia (Vologda and Orenburg regions) was studied. The contents of chemical elements in wool of the animals was determined using ICP-AES and ICP-MS. According to the results obtained, there were significant differences in the content of practically all elements (with the exception of B and Cu) in the wool of cows when comparing animals from Vologda and Orenburg. The study of the mineral composition of cow hair has shown that territorial features are the determining factor of elemental homeostasis and clearly demonstrate the need to take into account regional features when developing recommendations for correcting the elemental status of animals.
