| Abstract:
Liquorice (Glycyrrhiza glabra L.), a perennial herb, with rhizomatous, sarmentose, juicy roots, of great pharmacological interest, is widely spread as wild crop in Southern Italy, where it was harvested in the past to nourish a flourishing industry. Several trials were carried out to test the possibility of cultivation of this species, investigating into some issues of cultivation techniques. It was observed that the optimal temperature for rooting is around 15°C and the optimal cutting size for crop establishment is about 15–20 cm in length and 1.5–2.0 cm in diameter. The trials showed that yield was greatly affected by some cultivation techniques, such as the planting time, density and choice of cuttings for the crop establishment, temporary association and supplemental irrigation. Generally speaking, under the tested environmental conditions, the mean fresh root yield was found to be around 15–20 t ha-1, over a three-year period. This opens good prospects for this crop and hints a three-year cropping cycle. | |
