“…Increasing N rate increased the competitive ability of triticale causing a reduction in relative biomass yield of intercropped legume and as a consequence decreasing N fixation per unit area. The results are in agreement with those of Martin and Snaydon (1982) who reported an increase in root competitive ability of barley against field beans after N application. On the other hand, intercropped triticale was unable to utilize the fertilizer nitrogen for grain production to such an extent as in pure stand and this was reflected by reduced NUE with increasing N input.…”

“…Significantly higher N uptake by intercrop than by both species in pure stand indicates there were partially different sources of nitrogen for components of the intercrop. Complementary use of N in cereal-legume intercrops has been observed also by other authors (Martin andSnaydon 1982, Bulson et al 1997). Nitrogen fixation by field beans reduced competition from the legume for soil and fertilizer nitrogen causing the nutrient more available for triticale.…”

“…Management of nitrogen fertilizer also affects competitive interactions between components of an intercrop. Martin and Snaydon (1982) reported that an application of N fertilizer increased root competitive ability of barley intercropped with field beans, and when the only roots of the two species grown together N input caused reduction in relative yield total.…”

A field experiment of split-plot design was conducted in 1999 and 2000 on light soil to study the effect of different levels of mineral nitrogen fertilization: 0, 25 and 50 kg N/ha on dry ma�er yield, N uptake and N efficiency indices of spring triticale and field beans grown in pure stands and in intercrop. The intercrop was composed using half of the seeding densities from pure stands. Intercropping increased protein content in grain and plant biomass of triticale irrespective of N input. Increasing N rate from 0 to 25 kg/ha increased plant biomass yield of triticale and intercrop. Nitrogen uptake with grain and biomass of intercrop was significantly higher than by sole crops showing partial complementarity in N use by intercropped species despite strong dominance of triticale over field beans. The higher the N fertilizer rate, the lower was the gain from intercropping mainly due to increased suppression of field beans by triticale. Agronomic efficiency was similar for triticale and intercrop but it was significantly smaller for field beans indicating there were other limited resources hampering growth of the legume.

“…In contrast, IC significantly reduced mineral N uptake of field bean, which accounted for only a 3% N content in IC compared to 26% in SC. The increased proportion of N derived from N 2 fixation in legumes intercropped with cereals suggests that root competition was greater than shoot competition (Martin and Snaydon 1982, Hauggaard-Nielsen et al 2003, Trydeman-Knudsen et al 2004). The higher competitiveness of grass roots is likely due to their faster growth in autumn-winter and to their finer and deeper root system, allowing a more efficient exploitation of the soil volume and a higher nutrient uptake (Hauggaard-Nielsen et al 2009, Dordas andLithourgidis 2011).…”

Cereal/legume intercropping may improve resource use efficiency in agroecosystems and increase yield per unit surface area and yield stability. Two field bean (Vicia faba L.) and four barley (Hordeum vulgare L.) cultivars were mono-and intercropped (additive design) in a 2-year lysimeter experiment on a sandy loam soil. The aim was to test the effect of the cropping system on dry matter and N yield of forage, the residual effect on the subsequent ryegrass crop (Lolium multiflorum Lam. westerwoldicum), and NO 3 -N leaching in the rotation. Land equivalent ratios were 1.65 for dry matter and 1.67 for N yield, indicating a clear advantage of the intercrop over sole crops. Both species suffered from competition, especially in terms of N resources, but barley was less affected. Nitrate leaching was the lowest from intercrop. Preceding crop significantly affected dry matter, N content and NO 3 -N leaching of ryegrass. Field bean sole crop gave the highest benefits to ryegrass in terms of forage dry matter and N content, but also the highest NO 3 -N leaching, followed by the intercrop and the barley sole crop. Barley/field bean intercropping may be an effective strategy to reduce land requirements, N leaching losses and fertilizer inputs, thereby increasing the sustainability of farming systems.

“…Although the majority of research on multiple-crop systems has focused on aboveground effects on the component crops, belowground interactions have far more significant impacts on combined plant development (Martin and Snaydon 1982;Hauggaard-Nielsen and Jensen 2005;Thorsted et al 2006). Only recently attention has shifted towards the complexity of belowground interactions between crops and the soil system (Tosti and Thorup-Kristensen 2010).…”
