Metal nanoparticles are used in agriculture as trace elements for agricultural plants, as growth stimulants, and pesticides. Nanodisperse metals are known to have biological, antioxidant, and enzymatic activity. The article presents the results of research on oat of the “Skakun” variety, conducted in 2014-2017 in the conditions of the Agricultural technology station of RSATU (Ryazan region). The experiment was carried out on gray forest heavy loam soil, in 3 times repetition. Its predecessor is winter wheat. In the experiment, cobalt nanopowder (NP Co) and copper nanopowder (NP Cu) were used with a purity of 99, 98%, the size of metal particles was 20-40 nm. The effect of nanopowders of cobalt and copper metals and their combinations on the productive, physiological and biochemical parameters of oat plants in production conditions is shown. The best result was observed when using the preparation with a mixture of cobalt and copper nanoparticles at a concentration of 0.5 g per average seed rate per hectare - field germination increased by 5.0%, grain yield increased by 15.3%, grain protein content - by 2.0%, fat content - by 0.5% relative to the control.

“…An alternative to traditional forms of micronutrients can be nanopreparations containing metals (iron, cobult and copper) in the form of nanosized particles. The Scientific and Educational Center "Nano-and Biotechnologies" at Ryazan State Agrotechnological University, Russia, is studying the biological activity of metal nanopowders in various agricultural sectors (Polischuk et al, 2015a;Polischuk et al, 2018;Churilov et al, 2019), including the feeding of highly productive animals with the ability to catalyze biochemical processes in the body and increase metabolism (Nazarova et al, 2014;Miroshnikova et al, 2015;Sizova et al, 2016). With this background in mind, The aim of current study was to avaluate the effect of copper nanopowder on the mineral metabolism indicators during growth process of Holstein heifers.…”

The current study aimed to investigate the effect of copper nanopowder on physiological and mineral metabolism indicators of Holstein cattle during the growth process of the animal. There were two experimental groups (control and treatment) and each one included seven Holstein heifers. From the first month of each heifer in the experimental group, a suspension of copper nanoparticles in a dose of 0.04 mg/kg was orally administered daily to the usual diet. The biologically active additive was administered to the animal’s diet at intervals. The weight of the animals was measured monthly, a clinical blood test was performed, the mineral composition of the blood was studied, the mineral composition of animal hair was also examined. The findings indicated a positive dynamics in the increase of body weight in the treatment group, compared to the control group. As a result of clinical blood tests, it was noted that the number of erythrocytes, the level of hemoglobin, and hematocrit increased in the experimental animals due to copper nanoparticles compared to these parameters in these animals at the beginning of the tests. Mineral analysis of blood samples in the treatment group presented an increase in the levels of copper, potassium, iron, zinc, and manganese while in animals of the control groups there was an increase in sodium, calcium, and phosphorus. According to the blood serum and hair analysis, copper in the nanodispersed state indicated antagonistic effects on boron, silicon, antimony, molybdenum of the treatment group and there was a synergist in aluminum, titanium, manganese, cobalt, iron, and potassium levels compared to the beginning of the experiment. The obtained results indicated that the addition of copper nanopowder to the diet of experimental animals increased the growth, stimulated the function of hematopoiesis, and improved the characteristics of mineral metabolism of the Holstein heifers.
