We evaluate the forage yield and quality, species composition, and carrying capacity of oats and oat-vetch as fodder-cover crops, grown in almond orchards, under mineral or organic fertilizer and three harvesting regimes (“grazing,” “hay,” and “grain plus straw”). Also, we show preliminary results of almond yield. Differences in yield due to mineral and organic fertilization were only 9%. The carrying capacity was similar for all treatments. The almond yield was greater when the cover crop was removed early as “grazing.” Therefore, oats and oat-vetch could be used as cover crops in almond orchards if removed early by livestock grazing.
