The accumulation of waste products of phytopathogens in grain leads to a deterioration in its organoleptic properties, a decrease in germination, and mycotoxins pose a danger to human health. Thus, processing seed material to protect it from diseases and pests is one of the most economical plant protection measures. At the same time, due to the many harmful properties of chemicals - such as environmental hazards and high processing costs - it becomes advisable to search for safer methods. In this work, natural adsorbents based on clays of various origins were used to study their effect on the phytosanitary state of grain seeds during post-harvest processing. The study examined such indicators of the phytosanitary state of seed material as the initial contamination of seeds before storage and the prevalence and indices of disease development in the tillering phase after treating seeds with various clays. The results showed that, in general, treatment with adsorbents has a beneficial effect on the phytosanitary condition of grain seeds. Treatment of spring wheat seeds with white clay led to significantly lower rates of prevalence and development of root rot. A similar result was obtained in an experiment with winter wheat when seeds were treated with red clay. On rye, a decrease in the development of root rot was observed when treated with white and yellow clays, and on barley – with white and red; in the experiment with yellow clay, no positive effect was observed on barley.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":"25 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140696619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditionally, low-density polyethylene is used for these purposes due to its mechanical and barrier properties, resistance to all forms of degradation, simple processing of cover soil, and low cost. However, using polyethylene has several artificial and environmental risks associated with difficult biodegradability, the difficulty of its removal after the harvest cycle, and final disposal. Therefore, there is great interest in the use of biodegradable mulch films. Two groups of materials most suitable for producing biodegradable coatings are polysaccharides of natural origin and biopolymers of synthetic origin. Technological methods for producing biopolymers from raw natural material by extraction from biomass and chemical or biotechnological methods are analyzed. Data are presented on the potential of biodegradable mulch materials of natural origin, films based on polysaccharides, synthetic polymers, and those applied as a solution for possible replacement of traditional mulch materials. A comparison was made of the compositions of biodegradable coatings, their properties, and their effects when used. The prospects and ways of introducing biodegradable film materials into agricultural practice are summarized.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":"109 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140695318","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

According to current guidelines, experimental research, records, and observations were carried out. Strains of nodule bacteria Synorhizobium meliloty were provided by the Laboratory of Ecology of Symbiotic and Associative Rhizobacteria of the Federal State Budgetary Scientific Institution “All-Russian Research Institute of Agricultural Microbiology”. In seven years of research, the positive role of the studied factor in increasing the yield, nutritional, and energy value of alfalfa was established. The total collection of green mass in three experiments in variants with inoculation of alfalfa seeds with rhizobia strains increased by 4.0–15.2%, and the collection of dry matter increased by 6.8–21.7%. The most significant increase in the yield of green mass and dry matter in experiments 1 and 2 was provided by the primary production strain 425a and experiment 3 – by production strain 415b. Regarding quality indicators, in experiments 1 and 2, production inoculant 425a had an advantage, and in experiment 3, the promising strain A1 and production strain 415b had an advantage. For adaptive intensification of forage production, the creation of stable agrophytocenoses with alfalfa with inoculation of seeds with virulent active strains of rhizobia (mainly the main production strains 425a and 415b) is shown.","PeriodicalId":124451,"journal":{"name":"Bulletin of NSAU (Novosibirsk State Agrarian University)","volume":"82 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140695414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The primary substance of the oil is a complex of fatty acids, the composition of which has been well-studied for most genotypes. Still, studies have not been carried out in the group of sea buckthorn varieties of Altai selection. This study aimed to compare the fatty acid composition of the pulp of fruits and seeds of sea buckthorn selection by the Research Institute of Horticulture of Siberia, named after M.A. Lisavenko. The object of the study was the fruits of 13 sea buckthorn varieties belonging to the subspecies Hippophae rhamnoides ssp. mongolica, collected in 2014–2015. in the phase of full ripeness at the experimental sites of the Research Institute of Horticulture of Siberia, named after M.A. Lisavenko, is located in the forest-steppe of the Altai Territory. Determination of fatty acid composition was carried out in fruit pulp and sea buckthorn seeds using gas chromatography. Six fatty acids were identified in the fruit pulp of sea buckthorn, differing significantly in percentage. The predominant ones are palmitic (C16:0) and palmitoleic acids (C16:1), which account for more than 80% of all fatty acids. The most minor amounts are stearic (C18:0) and linolenic (C18:3) acids (2.32%). Sea buckthorn seed oil is dominated by unsaturated fatty acids (more than 90%): oleic (C18:1), linoleic (C18:2) and linolenic acid, and cis-vaccenic acid (C18:1-n7) are present. The largest share on average for varieties is linoleic acid (40.93%).

The subject of the survey is crushed zeolite from the Transcarpathian zeolite plant. It was revealed that the fractional composition of zeolites affects the timing of phenological phases in tomatoes. When planted in open ground on June 10, the age of the seedlings was 55 days. The time from planting to the beginning of flowering, on average over two years, was the shortest in the variant using zeolite fraction 1 mm (24 days) and the longest in the control (33 days). The first tomato harvest was done using a 1 mm fraction of zeolite on the 46th planting day. On average, mass harvest in variants with the addition of different types of zeolites occurred faster by seven days compared to the control. Standardity in all variants, including the control, was at a high level and ranged from 97.9 in the control to 98.9% in the variant, with the addition of zeolite fraction 1.5 mm during the period of mass fruiting and from 84.9 in the control to 98.0 % in the variant with the addition of zeolite fraction 1.5 mm when calculating the total yield. It has been proven that using zeolite substrates of the 1–1.5 mm fraction as a component for growing tomato plants in open ground on leached chernozem of the Northern Trans-Urals is an effective method. When zeolites of fractions 1 and 1.5 mm were included in the soil, the yield increased compared to the control by 3.5 and 3.9 kg per 1 m2, respectively. The average fruit weight was within the general requirements for the standard for this variety. However, within the variants, it ranged from 84 g in control to 141.5 g in the variant, adding a zeolite fraction of 1.5 mm. The addition of zeolite, especially the more significant fraction, smoothed out the lack of moisture, especially in 2021. In the variants with the addition of zeolites, the fruits were more important than the control by more than 1.5 times.
