Effect of different agroecological factors on yield and quality of peppermint

The present study shows the results of field plot experiments with peppermi nt (Mentha piperita L.) carried out in four different locations with differ ent climate in hilly-mountainous and lowland regions. Filed experiments wer e performed on soils differing in their pedological and agrochemical proper ties. Obtained yields varied more significantly in dependence on soil quali ty and climate than in qualitative traits (essential oil content, contents of macro- and microelements in plant tissues).
