The Effect of Fertilization with Spent Mushroom Substrate and Traditional Methods of Fertilization of Common Thyme (Thymus vulgaris L.) on Yield Quality and Antioxidant Properties of Herbal Material

This experiment was designed to determine the effect of spent mushroom substrate, farmyard manure, and mineral fertilization with nitrogen, phosphorus, potassium on yield quality raw material obtained from two cultivars (“Słoneczko” “De Dolj”) common thyme. Unfertilized plots thyme crops were included as control treatment. Different row spacings (30 cm 40 cm) represented second experimental factor. The highest total found in treatment NPK fertilization, but also treatments where substrate (SMS) applied at a ratio 50:50%. Fertilization SMS alone (100%) yielded smaller production effects, they higher than case manure. high suitability or supplemented different rates spring confirmed by best parameters antioxidant properties material. use wider spacing (40 resulted narrower one cm). significantly positively affected some analyzed harvested material, such as: essential oil content, polyphenol activity. cultivar “Słoneczko” proved be absolutely more beneficial terms quantity foreign Dolj”.
