Abstract
During the years 1970, 71 and 72 variations of calcium, phosphorus, potassium and magnesium levéis in Aragón lucerne at different stages of growth and vegetation cycles have been studied. On dry matter basic, P, K and Mg contents decreased as the maturity of the plant advanced (P < 0,05). Calcium levéis did not show this pattern. Differences in mineral content of samples from different vegetation cycles were not stastistically significant. However, there were significant variations (P < 0,05) on P and K contents from one year to another.
