Behaviour of fescue and orchardgrass cultivars in the IX Region of Chile

Oriella Romero Y.1, Hernán Acuña P.2 y Hernán F. Elizalde Y.3

During the fail of 1979, two trials were established to compare fescue (Festuca arundinacea) and orchardgrass (Dactylls glomerata) cultivars in a volcanic ash soil (“trumao”) under dryland conditions, at the Carillanca Experiment Station. Dry matter (DM.) production during five growing seasons was measured, in a complete block design with four replications. The first two seasons, the .fescue varieties of Mediterranean origin, Maris Kasba and Maris Jebel, produced Iess than the K-31, S-170 and Demeter. During the last three years, the Mediterranean vaneties were equal or better than the others, having always a better production (P < 0.05) during winter (June to August). Yields varied between 3 and 9 Ton D.M./ha. Orchardgrass produced between 3.5 and 9 Ton D.M./ha/year. Cambria had higher yields (P < 0.05) during the falI and produced more total D.M. in the second and fifth years. Sylvan and Cambria produced more in summer than Apanui, Potomac and S-26.
