The feasibility of replacing peat or perlite with rice hulls and ground kenaf core to grow a Mediterranean species (Pinus halepensis M.), was investigated. Treatments involved the following growing media: 70 peat:30 perlite as a control, 70 peat:30 rice hulls, 50 peat:50 rice hulls, kenaf (100%) and 60 kenaf:20 peat:20 rice hulls. The seedlings' quality and the physical and chemical properties of the substrates were evaluated. After this, the seedlings were planted in the field and their field performance was recorded. The results showed that the growth medium 70 peat:30 rice hulls can successfully be used for the production of P. halepensis, since the seedlings' nursery and field performance were similar to, or even better than those obtained with the control medium. The seedlings produced in the growth media containing kenaf did not attain a suitable planting size and showed poorer field performance than control seedlings.
