The experiment was carried out in soil culture in 3-fold repetition. Agrochemical parameters of soil: рН 6,2; the КСl humus of 2.6%; P O 204 mg/kg and K O 219 mg/kg soil. Four variants of the experiment were developed: control 1 (dry seeds), 2 5 2 control 2 (soaking seeds in water), NP Se inlay (semi-dry etching) and NP Se soaking (30 minutes before sowing at the rate of 0,1 g/ha of NP selenium). In the experiments, NP Se containing 3,7 mg of nanopreparation Se in 1 liter of water was used. The positive effect of selenium nanoparticles on the growth processes of maize seeds: germination, germination energy, growth force is shown. Se NP seed treatment increases germination energy by 6,90 and 9,13%, laboratory germination by 4,67 and 8,34%, growth strength by 26,32 and 31,05%, respectively, control 2 (soaking in water) and control 1 (dry change). Under adverse conditions, the use of selenium nanoparticles increases the growth of plants in height. Positive effect on the accumulation of starch in corn grains inlay NP Se, and soaking in this drug increases the content of protein fractions. The greatest increase in the yield of dry corn phytomass provides soaking seeds with selenium nanoparticles, which is caused by an increase in the yield of green corn mass.

Наведені результати досліджень використання протруйників та гуматів для передпосівної обробки насіння.  Встановлено, що додавання гуматів у суміші з протруйниками закономірно підвищувало показники польової схожості та кількості вузлових коренів порівняно з контролем. Середньорічні показники свідчать про закономірний вплив застосування стимуляторів на скорочення періоду «сівба–сходи», проте за несприятливих умов проростання застосування стимуляторів може відігравати дуже важливу роль для отримання дружних сходів. У випадку застосування гуматів польова схожість насіння зросла на 11–13 %. За несприятливих умов, що склалися на період проростання дія факторів посилювалася і збільшувався вплив таких взаємодій як «попередники–сорт» та «сорт–варіант обробки насіння». Утворення вузлових коренів також істотно залежало від варіанту обробки насіння. Найкращим показником характеризувався варіант досліду, де використовувався «1R Seed treatment», що в подальшому значною мірою вплинуло на формування врожайності. У всіх проведених дослідах відзначали позитивний вплив застосування для обробки насіння стимуляторів «Гуміфілд» та «1R Seed treatment» як у сумішах з протруйниками, так і у варіантах, де вони використовувалися окремо. The results of studies on the use of disinfectants and humates for presowing seed treatment are presented. It was found that the introduction of humates in a mixture with preservatives naturally increased the field germination and the number of nodal roots compared to the control. Average annual indices testify to the natural effect of the use of stimulants on the reduction of the period of «sowing–shoots», but under adverse conditions of germination the use of stimulants can play a very important role in obtaining amicable shoots. In the case of application of humates, the field germination of seeds increased by 11–13 %. Under unfavorable conditions prevailing during the germination period, the effect of the factors increased and the influence of such interactions as «precursors–grade» and «variety–variant of seed treatment» increased. The formation of nodal roots also significantly depended on the variant of seed treatment. The best indicator was a variant of the experiment, where «1R Seed treatment» was used, which subsequently significantly influenced the formation of yields. In all the experiments conducted, the positive effect of the use of stimulants «Humifield» and «1R Seed treatment» for seed treatment, both in mixtures with disinfectants, and in cases where they were used separately, was noted.

Подготовка посевного материала и его качество является одним из основных факторов получения высоких и устойчивых урожаев, поэтому при обработке семян также расширяется спектр способов их подготовки. Актуальность работы состоит в экологической направленности инновационной технологии обработки семян сельскохозяйственных культур озоновоздушным потоком взамен химического протравливания. Озоновоздушная смесь в различных концентрациях способствует повышению посевных качеств семян и подавлению патогенной микрофлоры. Представлены результаты исследований по изучению влияния предпосевного озонирования семян клевера лугового на их посевные качества и урожайность зелёной массы в условиях Костромской области. Исследования проводили в 2015 2017 гг. на опытном поле ФГБНУ Костромской НИИСХ . В исследованиях использовали клевер луговой сорта Сонет. Схема опыта включала две дозы предпосевной обработки семян (0,8 мг/м3 (Озон0,5) и 1,5 мг/м3 (Озон1,0) за 7 дней до посева озоновоздушным потоком в течение 20 минут) и контроль. Исследованиями доказано, что озонирование семян клевера лугового перед посевом положительно влияет на энергию прорастания (от 3 13), на высоту и облиственность растений первого и второго года жизни, повышает урожайность зелёной массы. Предпосевная обработка семян озоновоздушным потоком в варианте Озон0,5 обеспечила повышение урожайности от 9,4 до 14,6, при концентрации 1,5 мг/м3 до 4,8, по сравнению с контролем. В среднем за годы исследований в контрольном варианте урожайность составила 29,2 т/га, а в варианте Озон0,5 32,7 т/га.The preparation of seeds and its quality is one of the main factors for obtaining high and sustainable yields so when processing seeds the range of methods for their preparation is also expanding. The relevance of the work lies in the environmental focus of the innovative technology for treating seeds of agricultural crops with an ozoneair flow instead of chemical dressing. The ozoneair mixture in various concentrations helps to increase the sowing qualities of seeds and suppress pathogenic microflora. The results of researches on the effect of presowing ozonation of meadow clover seeds on their sowing qualities and yield of herbage in the conditions of the Kostroma region are presented. The researches were carried out in 2015 2017 on the experimental field of the Federal State Budgetary Scientific Institution Kostroma Agricultural Research Institute . Meadow clover Sonet was used in the researches. The experimental design included two doses of presowing treatment of seeds (0.8 mg/m3 (Ozone0.5) and 1.5 mg/m3 (Ozone1.0). Seven days before sowing by ozoneair flow for 20 minutes) and control. Researches have proven that the ozonation of meadow clover seeds before sowing has a positive effect on germination energy (from 3 13), on the height and foliage of plants in the first and second years of life and increases the yield of herbage. Presowing seed treatment with an ozoneair flow in the Ozone0.5 variant has provided an increase in yield from 9.4 to 14.6 at a concentration of 1.5 mg/m3 up to 4.8 compared with the control. On average over the years of researches the yield in the control variant was 29.2 t/ha and in the Ozone0.5 variant it was 32.7 t/ha.

The use of high-quality seeds in the production process of cropgrowing is one of the main criteria for obtaining a good harvest. The research goal is to study the effect of pre-sowing seed treatment with biological preparations on barley yield formation under the conditions of the Altai Re-gion’s Ob River area. The research was carried out in 2019 and 2020 in the Altai Region’s Ob River area. The research target was the Vorsinskiy barley variety and the biological preparations used for pre-sowing seed treatment. The ex-periment included 10 variants; of those 4 variants using biological preparations obtained based on processed agri-cultural and woodworking wastes, and top peat processed by autohydrolysis-explosion. The control consisted in seed treatment with distilled water. The results obtained showed that the use of biological preparations in barley cultivation had a positive effect on the final result -crop yield. The average results over two years of testing showed a wide range of yield variations in the experiment variants. The yield values varied from 2.15 t ha in the Variant no. 8 to 2.82 t ha in the Variant no. 5; the control -2.60 t ha. The yield value in the Variant no. 5 with the use of top peat preparation was the maximum in the experiment. On aver-age, over two years of research, the variability in the vari-ants was from the medium of 10% < Cv < 20% in the Vari-ants no. 2, 3, 4, 5, 7 to high Cv > 20% -Variants no. 6, 8, 9, 10. The maximum positive effect on the yield formation of the Vorsinskiy barley variety is exerted by pre-sowing seed treatment with the preparations based of plant residues (sunflower husk, oat chaff -Variants no. 3, 4), woodworking wastes (pine needles -Variant no. 2) and top peat (Variant no. 5) processed by autohydrolysis explosion.

SUMMARYIn a preliminary laboratory experiment in Iran, not reported here, 5 out of 30 plant materials incorporated into a highly calcareous soil had a positive effect on increasing the DTPA- (diethylenetriaminepentaacetic acid)-extractable Fe and all except one significantly increased the vegetative growth of sorghum. The plant materials included Lawsonia inermis L., Malva silvestris L., Zyzyphus nummularia Wak. and Lavandula carnopifolia L. A glasshouse study was repeated with two California soils pretreated with 0·5% Fe2O3 to determine if these organic materials have practical value in making Fe available to plants. A calcareous, Fe-deficient Hacienda (fine-loamy, mixed, thermic aquic natrargid) and a non-calcareous Yolo (fine-silty, mixed, non-acid, thermic typic xerothents). The previously mentioned organic materials and Laminaria saccharina L. (Lamour) were incorporated into the soils at two rates, 15000 and 20000μg/g, as air dry and in ash form. An adequate supply of major and micronutrients other than Fe was ensured. Other treatments included 5 μg Fe/g as FeSO4, Fe-138 chelate and control. All of the plant materials with the exception of L. carnopifolia significantly increased dry-matter yield and Fe, Zn, Cu and Mn uptake by sorghum in the Hacienda soil. In the Yolo soil the above were not significant. Thin-layer chromatography of the extracts of the plant materials revealed the presence of significant quantities of phenolic substances.
