Productivity and growth of vegetables planted as intercrops were investigated in a three-year experiment (2007-2009) according to organic farming rules in the northeast of Slovenia. White cabbage (<i>Brassica oleracea</i> var. <i>capitata</i> f. <i>alba</i>) as the main crop was planted together with intercrops: head lettuce (<i>Lactuca sativa</i> var. <i>capitata</i>), bush bean (<i>Phaseolus vulgaris</i>), red beet (<i>Beta vulgaris</i> ssp. <i>rubra</i>), tomato (<i>Lycopersicum esculentum</i>), leek (<i>Allium porrum</i>), and celery (<i>Apium graveolens</i>). The market yield of cabbage as a sole crop (41.07 t ha<sup>-1</sup>) did not differ to intercropping production with salad and red beet; yields of cabbage in intercropping with celery, leek, beans and tomato were significantly lower. All intercrops had land equivalent ratios (LER) >1.00 and the highest LER (1.62) was reached in cabbage and tomato intercropping due to the same density of tomato as an intercrop and as a sole crop. The intercropping production of white cabbage with the studied vegetables is more productive than sole cropping in terms of land use efficiency.
