Portuguese annual mediterranean pastures: an eonomic approach to understand sown pastures failure
| Resumo: | After Portugal joined the ECC, in 1986, huge land use changes occurred: cereal crops área was strongly reduced; native pastures (low productive) área sharply increased (2.1 fold); sown pastures (hhigh productive legumes and grasses mixtures) area remain unchnaged. Thus, pasture production potencial is far from fulfilled.Farmers resits sowing improved cultivars, arguing their low persistency. Therefore we tested the hypothesis that the low persistence of improved cultivars reduces the profit of the sown pastures. |
