For organic production in mountain areas, fields of aromatic and medicinal plants are becoming more mechanized in order to reduce the workforce needs. Cultivation fields are established either by direct sowing or by planting. The effect of the cultivation technique was studied on yield and quality of thyme (Thymus vulgaris L.), sage (Salvia officinalis L.) and marshmallow (Althaea officinalis L.). For all three species, dry matter and active compounds production was hardly affected. However, sowing is preferred to planting for marshmallow because taproots are smaller and therefore easier to harvest, wash and dry. To choose the method of installation, yield and quality are not significant factors. Weed pressure, possibility of mechanization and irrigation, workforce availability and post-harvest factors are more decisive to determine the better strategy.
