Abstract

The possibilities of cultivating two spontaneous herbaceous species of the Iberian Peninsula (Onopordum nervosum Boiss and Cynara cardunculus L.) as sources of raw materials are considered. Sampling for growth and chemical analysis of the biomass was carried out along the vegetative cycle of plants grown in experimental parcels established in Madrid. Biomass production evaluation was performed at the end of the two cultivation cycles, in August 1988 and August 1989. Results of final biomass production in 0. nervosum varied between 6.2 and 22 tons dry matter/ha, depending on culture conditions and locality. C. cardunculus yields were between 20 and 30 tons dry matter/ha, depending mainly on localities. The results indicate that C. cardunculus seems to be better than 0. nervosum for lignocellulosic biomass production in marginal lands in the south of Europe which have a continental climate.
