Abstract
Studied were the changes in the nitrate-nitrite content of maize grown on areas treated with herbazine-50 and artificial nitrogen fertilizers. The chemical analysis of various parts of the plant (stem. leaves, flowers and grains) revealed that the content of nitrates and nitrites was highest in the ears, and lowest in the leaves. Highest was also the content of nitrates and nitrites in all parts of the plant in maize from areas treated with herbazine-50 at the rate of 4 kg of a. i. per hectare as well as with artificial nitrogen fertilizers (ammonium nitrate and superphosphate at 450 kg/ha), followed by maize obtained from areas where ammonium nitrate and superphosphate at 450 kg/ha were introduced only. Slightly lower amounts of nitrates and nitrites were found in maize from areas treated with herbazine-50 at 4 kg/ha only, and lowest was their content in maize from areas that were neither fertilized nor treated with herbazine-50.
