“…It has been proven that in plant mineral nutrition, apart from macronutrients such as nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), and others, micronutrients like boron (B), manganese (Mn), copper (Cu), zinc (Zn), molybdenum (Mo), and cobalt (Co) also play a significant role. Substances containing microelements are widely used in the cultivation of grains, grain legumes [4][5][6][7], and vegetables [8]. In this case, the seeds Microelements ensure many physiological and biochemical processes within the lifecycle of plants.…”

Background: Microelements are crucial for numerous physiological and biochemical processes in plant life. They constitute parts of various vitamins and enzymes, stimulate respiration, and accelerate oxidation and regeneration reactions, positively impacting protein metabolism in plant organisms. Objective: Considering the significant role of microelements in living organisms, our aim is to investigate the effectiveness of applying microfertilizers and biohumus on the growth, development, and quality of winter wheat and winter barley. We conducted field experiments and laboratory research to analyze the impact of trace element content in the soil at our experimental sites. This research holds particular significance amidst the ongoing global climate changes, emphasizing the urgency and relevance of our study․ Methods: Field experiments, both in winter wheat and winter barley, were set up with three replications, with the same fertilization scheme. The size of each plot was 30 m2, and the size of the experimental field in each crop area was 630 m2 consisting of the following types: 1. Control (non-fertilized); 2. Background: biohummus t/ha; 3. Background+Mn (MnSO4 4H2O); 4. Background +Cu (CuSO4. 5H2O); 5. Background+B (Na2 B407.10 H2O); 6. Background + Mo (HH4)2MoO4; 7. Background +Zn (ZnSO45H2O): Microfertilizers were used for pre-sowing seed treatment. Results: The three-year results of the studies revealed that the amount of harvest and the quality indicators of these crops increased from the application of molybdenum, manganese, and copper in the sowing of autumn wheat and autumn barley on the background of biohumus. The increase of the autumn wheat crop under the influence of these elements was 3.3-6.4 c/ha (6.9-13.3%), and the increase of the autumn barley grain crop compared to the biohumus background was 2.6-5.4 c/ha. ha, or 6.5-13.4%. A certain increase in the nitrogen content of wheat and barley grains can be seen as an indicator of a protein problem necessary for life. According to research, it was found that the nitrogen content in the grains of spikelets is high in the versions that received molybdenum, manganese, and copper. Specifically, for wheat, the nitrogen content ranges from 2.64-2.68% for Mo, 2.53-2.57% for Cu, and for barley grains, it ranges from 2.16-2.24% for Mo, 2.08-2.10% for Cu, and 2.02-2.07% for Mn. Simultaneously with the studies, it was proved that the crop yield and quality indicators did not undergo significant changes from the application of Zn and B, which is explained by the higher content of the total and mobile forms of these elements in the soil. Conclusion: In the practice of fertilizing grain crops such as wheat and barley, it's essential to judiciously use specific micro fertilizers like molybdenum ammonium (NH4MoO4), manganese sulfate (MnSO4 · 4H2O), or copper sulfate (CuSO4 · 5H2O). These should be applied alongside organic fertilizers to ensure that the crops receive a comprehensive supply of both microelements and macroelements. This approach not only guarantees the production of high-quality crops but also plays a pivotal role in managing the protein content within them, which is crucial for nutritional value and overall crop health.

“…За счет малых размеров и электронейтральности наноматериалы легко проникают через мембрану клетки, а вследствие значительной удельной поверхности имеют большую реакционную способность (4)(5)(6). К перспективным наноматериалам, потенциально способным повысить устойчивость растений к стрессорам биотической и абиотической природы, относят углеродные и кремнезольные наносоставы (7)(8).…”

Яровой ячмень (Hordeum vulgare L.) -основная зернофуражная культура, ежегодно занимающая около 40 % посевных площадей на Северо-Западе России. В последние годы в мировой и отечественной науке обозначился явный интерес к использованию в защите растений наноматериалов и нанотехнологий, который обусловлен их уникальными свойствами и высокой эффективностью в низких концентрациях. В настоящей работе впервые показано влияние углеродных и кремнезольных наносоставов на семенную инфекцию, а также поражение растений ярового ячменя корневыми гнилями и листовыми болезнями. Показано, что более сильный защитный эффект проявился при применении наносоставов на сорте ярового ячменя Атаман с более длительным периодом вегетации и большей восприимчивостью к основным болезням. Впервые установлено наличие аддитивного эффекта при комбинированной обработке семян и вегетирующих растений наносоставами с химическими или биологическими фунгицидами с потенциальной возможностью снижения дозировки последних. Нашей целью было изучение эффективности новых композиций на основе углеродных и кремнезольных наноматериалов в защите ярового ячменя от болезней на Северо-Западе Российской Федерации. Исследования проводили на экспериментальной базе Меньковского филиала ФГБНУ АФИ (Гатчинский р-н, Ленинградская обл.) в 2017-2018 годах. На первом этапе исследований в 2017 году была изучена эффективность двух перспективных наносоставов для защиты ярового ячменя от корневых гнилей и листовых болезней. На разных по срокам вегетации сортах Ленинградский и Атаман были заложены два опыта -по обработке наносоставами посевного материала и вегетирующих растений. Кремнезольная композиция НКтэос была синтезирована по оригинальной золь-гель технологии (на основе кислотного гидролиза с последующей поликонденсацией тетраэтилового эфира ортокремниевой кислоты или тетраэтоксисилана, с добавками в золь растворов солей макро-и микроэлементов и допантов -шихты детонационного наноалмаза, легированной бором, или диоксида титана в форме анатаза). Подготовку наносостава на основе производных фуллерена с метионином или треонином осуществляли посредством растворения в воде соединений микроэлементов и добавления 0,001 % (при обработке семян) или 0,00001 % (при некорневой обработке) раствора аминокислотного производного фуллерена С60 с треонином или с метионином. Варианты опыта включали совместное применение наносоставов с химическими и биологическими фунгицидами, а также фунгицидов с кремнийсодержащим хелатным микроудобрением. Зараженность зерна фитопатогенами определяли с использованием питательных сред. Учет развития корневых гнилей проводили в фазы всходов, кущения, выхода в трубку и колошения, листовых болезней -в фазу начала колошения ячменя, далее через 10, 20 и 30 сут. На втором этапе исследований в 2018 году оценивали эффективность технологической схемы применения новых наносоставов в защите ярового ячменя сорта Ленинградский от болезней. Опыт включал два блока: с обработкой наносоставами семенного материала, с обработкой семян и вегетирующих растений. Показано, что изученные...

The studies were conducted in the northern forest-steppe of the Tyumen region. Under laboratory and field conditions, different forms and dosages of macro- and micronutrient nanoparticles and associated substances were tested in the treatment of seeds and plants of spring triticale and wheat. The preparations had a positive effect on seed germination, while higher rates reduced energy and germination. The germination energy and germination of triticale seeds increased by 4-10% with the application of preparations containing nanoparticles of copper, manganese, molybdenum, biogenic iron, Titan M. Treatment of daily seedlings with manganese, calcium, molybdenum, Titan M, biogenic iron, boron, potassium increased sprout length by 7.8-25% and sprout weight by 6-8% by day 7. Only already developing sprouts responded to the application of potassium. It was noted that the application of biogenic iron causes a 4-10% decrease in laboratory germination of seeds, but promotes the development of the main root. Its increase was 9-12% compared to the control. The inclusion of biogenic iron and silicon in the mixture to the chemical dressing reduced the effectiveness against root rot from 18% at the beginning of the growing season to 30% by the harvesting period. The application of biogenic iron increased the yield by 0,5-0,6 t/ha or 23% in the system of complex crop protection compared to the control and by 0,16-0,23 t/ha with the standard scheme of crop protection. A positive effect of biogenic iron in the treatment of plants during the earing phase as a separate element of the technology and in a tank mixture with fungicides was noted.
