| The most frequently used substrate for the production of covered root seedlings is peat, the extraction of which is under scrutiny due to its negative environmental impact; however, the use of Sphagnum moss in adequate mixtures constitutes a possible alternative. Lettuce seeds (Lactuca sativa L.) were sown in Polystyrene trays (240 alveoli, 24 cm³) to test four substrates, 50% Sphagnum moss mixed with 50% humus or compost and 60% Sphagnum moss with 40% humus or compost, and commercial peat was used as a control. A dose (2.5 or 3.5 gL-1) of controlled-release fertilizer (CRF) was added to all substrates except for the control mix, and the substrates were subsequently irrigated with or without a fertilizer solution. The study was conducted under shaded... |
