A study of the evaluation and selection of cover crops to improve soil management in an organic orchard of raspberry (
Rubus idaeus
L.) was carried out. The evaluated cover crops were: a mixture of subterranean clover (
Trifolium subterraneum
L.) and balansa clover (
T. michelianum Savi), birdsfoot trefoil (
Lotus corniculatus
L.), white clover (
T. repens L.), fescue (
Festuca arundinacea
Schreb.), a mixture of white clover and fescue, and a control without vegetation. The trial was conducted in Chillán, Chile (36°37' S, 72°00' W), during two seasons. The experimental design was randomized blocks with four replicates. Planting distance between raspberry rows was 3 m, and each experimental plot was 60 m
2. Covers that included white clover as a single species and white clover in mixture with tall fescue had the highest plant density (828 and 1788 plant m
-2, in the second year, respectively), biomass (9.3 and 10.4 t DM ha
-1 yr
-1, in the second year, respectively) and specific contribution of the sown species (more than 90% contribution of sown species). Mixture of annual species did not have a good performance, particularly during the second season. A clear effect of the covers on soil content of nitrogen (N) and potassium (K) was found; however, soil organic matter content and pH were not affected. Weed growth was best controlled by the cover crops that included fescue and/or white clover.
