Abstract:Kompost iz izrabljenega gobjega substrata (IGS) bukovega ostrigarja (Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm.) je pomemben vir za trajnostno kmetijstvo, saj omogoča recikliranje odpadnega materiala po pridelavi gob. V diplomskem delu smo s kalitvenim testom na vrtni kreši (Lepidium sativum L.) ocenjevali zrelost komposta. IGS smo kompostirali 84 dni, vzorčili na 14 dni in iz vzorcev pripravili vodne ekstrakte (1 : 10) za kalitvene teste v petrijevkah pri 25 °C. Analizirali smo indekse kalivosti in dolžino korenin ter nadzemnih delov rastlin. Skupna kalivost je bila pri vseh obravnavanjih visoka (95–99,9 %) in primerljiva s kontrolo (99,5 %). Jasne razlike so se pokazale pri indeksih kalitve, ki opišejo tudi dinamiko procesa: vzorci, kompostirani 14 in 28 dni, so izkazali fitotoksičnost, medtem ko so bili po 56 dneh rezultati primerljivi s kontrolo. V kasnejših obdobjih (70–84 dni) je kompost celo spodbujal rast nadzemnega dela, v celoti pa so bile rastline dolge 110–118 mm in primerljive s kontrolo (108 mm). Na podlagi rezultatov sklepamo, da IGS doseže primerno zrelost za uporabo kot gnojilo po najmanj 56 dneh kompostiranja.

Title:Germination of garden cress as an indicator of compost maturity from spent mushroom substrate
Abstract:Compost derived from spent mushroom substrate (SMS) of oyster mushroom (Pleurotus ostreatus (Jacq. ex Fr.) P. Kumm.) represents a valuable resource for sustainable agriculture by facilitating the recycling of waste material from mushroom cultivation. This thesis evaluates the maturity of SMS compost using germination tests with garden cress (Lepidium sativum L.). The SMS was composted for 84 days, with samples collected every 14 days. Water extracts (1:10 ratio) were prepared for germination tests conducted in Petri dishes at 25 °C. Germination indices as well as root and shoot lengths were assessed.Total germination across all samples was high (95–99.9%) and comparable to the control (99.5%). However, germination indices, which describe the dynamics of the process, revealed clear differences. Samples composted for 14 and 28 days exhibited phytotoxicity, whereas those composted for at least 56 days produced results comparable to the control. At later stages (70–84 days), the compost even stimulated shoot growth, with plants reaching a total length of 110–118 mm, similar to the control (108 mm).
