YIELD AND QUALITY OF TRITICALE CV TRUJILLO AND BARLEY CV FLIKA GROWN FOR DIFFERENT END-USES IN A MEDITERRANEAN ENVIRONMENT

Two field experiments were established in north-east Spain in order to compare yield and quality for different end-uses, and to ascertain th e optimum stage for forage harvest of triticale Trujillo and barley Fl ika. The two genotypes had a similar grain yield, but the grain of Fli ka had higher mineral, protein and energy contents, and its straw was also richer in minerals than Trujillo. When forage was removed at the beginning of jointing and grain was harvested in the regrowths, Trujil lo produced 23% more forage than Flika, but the reduction caused by cl ipping on grain yield was more severe in triticale than in barley. For age removal reduced digestible crude protein content in the grain. Tru jillo yielded more forage than Flika in some plant stages, and a simil ar amount in others. Forage yield was maximum at late milk-early dough stage. The forage of Flika was, on average, richer in minerals, prote in and milk folder units. Otherwise, the forage of Trujillo had more f ibre and lignin.
