| Mixed intercropping of spring barley (Hordeum vulgare L.) with field pea (Pisum sativum L.), faba bean (Vicia faba var. minor L.) or narrow-leafed lupin (Lupinus angustifolius L.) was compared to sole cropping in two field experiments at different locations, on a sandy loam soil and a sandy soil, in Denmark in 2001. Grain legumes were dominant in intercrops on the sandy loam soil, except for lupin, whereas barley was dominant in intercrops on the sandy soil site. Combined intercrop grain yields were comparable to grain yields of the respective sole cropped grain legume or sole cropped, fertilized barley on each soil site. On the sandy loam soil, pea-barley and faba bean-barley intercrops increased the proportion of plant N derived from N2 fixation in... |

| Intercropping advantages may be influenced by both plant density and relative frequency of the intercrop components. In a field study barley (Hordeum vulgare L.) and pea (Pisum sativum L.) were sole cropped and intercropped at three densities, corresponding to i) half of the recommended, ii) the recommended and iii) twice the recommended plant density. Two intercrops combinations were included holding 1/3pea+2/3barley and 2/3pea+1/3barley relative to the sole crop densities employed. For three growth intervals within the whole growing period, the relative performance and interactions between the two crops were assessed using the Relative Efficiency Index (REIc). The relative performance of the two species varied over the growing season and was influenced... |
