Woody and semi-woody cuttings including olive (Olea europaea), rosemary (Salvia rosmarinus), and other Mediterranean aromatic species were propagated under controlled greenhouse conditions. Semi-hardwood cuttings were established in rockwool cubes for substrate-based rooting, while aeroponic propagation systems were used particularly for olive cuttings to enhance root initiation through fine mist nutrient delivery. Environmental parameters such as humidity, temperature, and irrigation frequency were carefully monitored to optimize rooting percentage, plant uniformity, and overall propagation efficiency. In addition, a floating hydroponic system was implemented for four different onion cultivars to evaluate morphological characteristics and yield production under soilless cultivation conditions.
