The aim of this work is to improve pasture production in the semiarid mountain areas in the North-eastern Iberian Peninsula in order to optimize the management of livestock farms. Three experiments were carried out: (i) pasture improvement of abandoned fields invaded by Genista scorpius (L.) DC by clearing and mineral fertilization; (ii) establishment of sown meadows; and (iii) improvement of drought grasslands by mineral fertilization. The annual average yields obtained in these experiments were 1439, 4291 and 3948 kg DM per ha, respectively. Eighty percent of the forage yield was obtained in the May-July period and the remaining in September. Therefore, animals were short of pastures at least six months a year. Present stocking rate is 0.21 LU per ha, and it could be increased to 0.32 LU per ha, if pasture production is improved
