Abstract
In field and pot experiments the effect of selected pesticides on the nitrogenase activity, number of soil microorganisms, and yield of hybrid lucerne was investigated. The obtained results show that crop protection preparations applied in the experiment (seed dressing compound Funaben T and Pivot 100SL herbicide) reduced the activity of nitrogenase in the active strain of Sinorhizobium meliloti both under conditions of pot and field experiments. In addition, the authors observed a noxious influence of the applied pesticides on nodulation, root development and yield of lucerne. Furthermore, in the first days after their application, the employed herbicide and fungicide inhibited multiplication of soil microorganisms under lucerne plantations, while later they were found to stimulate their multiplication.
