Application Of Bioeffectors For The Maize Growth In The Field Conditions

Preparates containing active microorganisms (bacteria, fungus) were tested in the field experiment with maize (Zea mays L.) on cambisol at Lipa site in combination with phosphorus (rock phosphate or triple superphosphate) and nitrogen fertilizers (calcium nitrate or ammonium sulfate with a nitrification inhibitor). Application of active microorganisms had statistically significant effect only on the sulfur content, which was probably due to the application of ammonium sulphate. Due to relatively balanced content of other selected elements in plants as well as above ground dry mass yield among treatments, it is not possible to clearly prove positive effect of bioeffectors.
