The possibility of using biopreparations based on nanoparticles of biogenic metals in crop production and plant protection

Abstract

Modern agricultural production requires innovative technologies. For a labile technological process of grain growing the following things are necessary: precise (coordinate) farming, crops protection in the form of controlled coexistence with undesirable life forms and a single pre-treatment with biopreparations based on biogenic metal nanoparticles. Physical-chemical properties of nanoparticles contribute to biocompatibility and biological activity when interacting with wheat and other crops. The paper shows relationship between the size of metal nanoparticles and their effect on wheat seedlings at concentrations of 0.001-1.000 g/t. The activity of superoxide dismutase and catalase in the crops significantly decreased when maximum morpho-physiological parameters and increased sharply at concentrations above 100 g/t and 10 g/t, respectively, for nanoparticles sized 35-60 nm and up to 20 nm. For nanoparticles sized 35-60 nm the stability limit was the concentration of nanoparticles much higher than 100 g/t, and for those up to 20 nm it was 0.001-10 g/t. The content of hormone indole acetic acid increased under the action of nanoparticles, which increased energy efficiency of plant respiration, activity of enzymatic reactions and wheat yield and grain quality when strengthening the seedlings’ viability, reducing the effect of weeds to minimum.

Soil Bio-Impact Effectiveness for the Optimal Multicriterial Environmental Sustainability in Crop Production

“…The stability limit of 35-60 nm nanoparticles was much higher than the concentration of 100 g/t nanoparticles, and up to 20 nm-0.001-10 g/t. The content of the hormone indole acetic acid was increased by exposure to nanoparticles, which increased the energy efficiency of plant respiration, the activity of enzymatic reactions, and the quality of wheat yields and grains by enhancing seedling viability while minimizing weed exposure [43]. The main trend in modern crop production is the expansion of the use of plant protection solutions and technologies, ensuring not only the effective management of pest populations, but also the production of environmentally friendly agricultural products with a minimal anthropogenic impact on agriculture.…”

Photosynthetic activity and productivity of potato plants when using foliar dressings with complex micronutrients and humate

“…The biological value of these fertilizers is due to the high content in an accessible form of the main nutrients -nitrogen, phosphorus, potassium, as well as a wide microelement composition, including Mg, S, Fe, Mn, B, Zn, Cu, Mo, Co, Se. A full composition and an accessible form allow effective compensation for the nutritional needs of potato plants in key phases of development, activation of photosynthesis and growth processes, and immunity increase [6][7][8][9].…”
