The formation of fiber flax yield and quality parameters depends on many soil-climatic, breedinggenetic, as well as anthropogenic factors. The quality of flax fiber is a combination of a number of features and properties that depend on the varietal characteristics of plants, the conditions of their cultivation, technologies for harvesting and straw retting, as well as on the processing modes of raw materials. During plant vegetation (90-130 days) many factors such as soil conditions (pH 4.8-5.5, humus 1.8-2.5%, P2O5 and K2O – 150-200 and 100-200 mg/kg, respectively) and the area of plant nutrition (15-30 million seeds/ha), temperature regime (the sum of active temperatures 1000-1800ºC), water supplying (400-430 units of water mass to create 1 unit of dry matter) and insolation (the arrival of FAR during the growing season 20-25 kcal / cm²), contamination of weeds (more than 60 annual and perennial species) and pests (more than 200 types of fungal, bacterial and viral diseases), features of phytosanitary measures (more than 50 chemicals) and agrotechnologic manners (Federal Register of technologies for the production of crop products) have a great influence on the quality of flax raw materials and can be a limit factor. Environmentally hazardous pollution of air, water and soil - the main components for the production of fiber flax – strongly affects the yield and quality of flax products. The development of waste-free environmentally friendly technologies for the cultivation, harvesting and processing of flax is an urgent task of scientific support of the industry. The main environmental factors affecting the yield and quality of fiber flax are discussed in the article.

Abstract Currently, despite of the active development of agriculture and the cultivation of many species, the use of wild food plants is relevant. Ferns also belong to such plants. Eight species of edible ferns grow in the Amur Region, of which 6 species are widespread and form large thickets. The population of the Amur Region uses 4 species for food, the most common is Pteridium japonicum, rarely –Athyrium sinense, Athyrium monomachii, Dryopteris expansa. The literature data on bracken harvesting on the territory of the Amur Region from 1970 to 2019 are presented. It was revealed that the collection takes place spontaneously and unsystematically. Irrational harvesting of raw materials leads to a decrease in yield and quality of harvested products. To restore bracken thickets after collecting, a recovery period of 4-8 years is required. Schemes for the use of fern populations are proposed, taking into account the period of their recovery. For a reasonable recommendation for the use of Athyrium sinense, Athyrium monomachii, Dryopteris expansa, Onoclea interrupta, Diplazium sibiricum in food, it is necessary to conduct research on their chemical composition, nutritional value, methods of preparation and storage.

The article describes a more environmentally friendly method to produce pectin compared to the classical acid scheme, which requires the use of strong mineral acids and toxic solvents. This method of obtaining pectin, like other analogs of the classical method, causes a decrease in the yield of the final product. This study aims to find ways of eliminating these barriers and increase the yield of pectin. The paper investigates the possibility to increase the yield of pectin obtained by acid hydrolysis applying citric acid through the use of preliminary microwave exposure to citrus raw materials. The work compares pectin quality indicators, such as the degree of esterification, molecular weight and gelation, for raw materials dried by the convective method and the combined method consisting of microwave pretreatment and blowing dry air. Curves of comparable pre-drying methods are presented. The rate of pectin yield at the stages of hydrolysis depending on the drying methods is analyzed. Optimal power modes for preliminary microwave drying of citrus raw materials are selected. The data obtained are valuable for both development and improvement of industrial technology of pectin production using environmental methods of extraction without the use of strong mineral acids to increase the yield and quality of pectin.

Under the conditions of changing biotic properties of terroir, it is relevant to establish the patterns of influence of different norms of the load of a grape bush in its own rooted and grafted culture on the quality of grapes, as well as the aesthetic and biological value of wine products in Russia. The objects of research were grapes and wine material of the Krasnostop AZOS variety in a grafted and rooted culture with variants of different load of shoots on the bush. The experience of studying the influence of various agrotechnical methods on the productivity of a grape plant and the quality of wine material was laid in the Anapo-Taman climatic zone of the Krasnodar Territory of Russia. The highest yield of the Krasnostop AZOS variety during the years of the study was obtained in the variant of own-rooted grape growing with its load of 36-40 shoots per bush. In our studies, there is a tendency to an increase in sugar content, and a decrease in the titratable acidity of grapes when growing vineyards of the Krasnostop AZOS variety in their own rooted culture. The most optimal ratio of sugar content and titratable acidity in the experiment was possessed by grapes from a variant of own-rooted culture with a load of 36-40 shoots/bush, here the glucoacedometric parameter was 4.36. In the studied variants, the largest amount of phenolic substances was found in wine material from self-rooted grapes with a load of 36-40 shoots per bush — 4130 mg/dm3. This had a positive effect on the organoleptic evaluation of this sample. The maximum total content of substances from a number of biologically active substances was found in wine from grape raw materials obtained from a grafted culture (134.9-147.9 mg/dm3). In 2018-2019, from the organoleptic side, wine materials from grapes of own-rooted culture proved to be of the highest quality. This advantage over the grafted crop was traced in all variants of rationing the load by the shoots of grape bushes.

Ecosystem degradation forces us to introduce highly productive, environmentally friendly biotechnologies in agricultural production. In this regard, interest in organic farming is growing. Demand for organic products is ahead of supply. This, in its turn, causes interest in substances that, on the one hand, are safe for the environment, and on the other hand, increase yield and quality of crops. These substances include biostimulants. They stimulate the natural processes of assimilation of nutrients, increase stress resistance of plants. In this regard, keratin-containing raw materials deserve special attention, which, in terms of chemical composition, is a protein concentrate (90-95%) . But its use is limited due to the low functionality of the keratin protein of this raw material. Enzymatic keratin hydrolysis will provide a biostimulant for plants with a high content of amino acids. The aim of the study was to develop an enzymatic method for keratin hydrolysis with a high content of amino acids in the final product. Fermentation was carried out by Str. chromogeness.g. 0832 proteinase. The content of soluble protein, peptides and amino acids was carried out photocolorimetrically. Temperature (4000C) and pH (8.0) conditions of Str. chromogeness.g. 0832 enzyme complex have been determined, which allowed further hydrolysis of keratin-containing raw materials with a maximum yield of final products - amino acids (99.57 g/100g). Treatment of corn seeds with the obtained amino acid solution enabled to increase growth-promoting activity by 48%.
