The effect of a mixture of iron and nickel nanopowders of various concentrations on the growth and yield of corn

Abstract

This paper shows the effect of various doses of a mixture of nanopowders of metals-microelements of iron and nickel (Fe + Ni) on the growth of corn, yield and its structure. Various doses of a mixture of Fe+Ni nanopowders were studied in the range of 0.5-2.0 g/t for corn ROSS 145 MB (grain hybrid). A mixture of iron and nickel nanopowders is effective in dressing corn before sowing. When using a dose of NP Fe + Ni 1.0 g/t, the height of plants in the phase of 5-6 leaves increased by 7.1%, in the flowering phase the leaf area increased by 18.4% higher than the control. It is shown that a mixture of Fe+Ni nanopowders 1.0 g/t increased the yield of green mass with cobs by 12.6%, cobs without a wrapper - by 14.3%, the weight of 10 cobs - by 185 g or 10.9% higher than the control. Under the influence of the optimal dose of nanopowders NP Fe + Ni 1.0 g/t in corn grain, the ash level increased by 0.18%, crude protein - by 1.4%, the amount of fat practically did not change. The content of vitamins has changed significantly, for example, vitamin C in the experiment is almost 2 times higher than the control, vitamin A - by 48%, vitamin E - lower than the control by 20%.
