Abstract
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.

8 of 14 groups shown: named compounds and organisms first, then groups whose results differ (checked claim by claim), then those with positive and negative results, then the smaller groups.
Claims are grouped by organism, treatment and what was measured or targeted. A paper counts as positive when any of its claims in the group is positive.
