Trial comparing improvement techniques of unirrigated Medliterranean pastures, on acid soil, under covering of an old olive grove has been installed on N. S. Mércules Farm (High School of Agriculture -Castelo Branco). There were high significant differences (P<0.01) between treatments for total matter production with emphasis on the response of natural pasture to fertilization. Yield was correlated with seed reserve of annual legumes in soil. Some pasture improvement techniques decreased consistently olive production.
