Intercropping Maize and Faba Bean for Silage Under Swedish Climate Conditions

“…However, it has been shown that faba bean growth may be facilitated when intercropped with maize compared with cultivation of the crops separately [14]. Nitrogen fertilisation did not have any effect on the yield of faba bean in the present study (Table 2), but it has been shown that addition of nitrogen can increase yield of faba bean [7,24], or it can inhibit nitrogen fixation in legumes [36]. Intercropping may in turn alleviate the inhibitory effect of nitrogen fertilisation by increasing nodule biomass, which has been shown for faba bean intercropped with maize [22].…”

Magnitude and farm-economic value of grain legume pre-crop benefits in Europe: A review

“…Also reduced yields of a vetch-barley rotation have been reported with reduced tillage in central Spain (Soldevilla-Martinez et al, 2013), but this may not negatively affect GM considering potential cost reductions. Applying reduced tillage to all crops in the rotation is also feasible, as the grain legume crops themselves were found to react with maintained or even increased yields to reduced or zero tillage (López-Bellido et al, 2003Ozpinar and Ozpinar, 2011;Giambalvo et al, 2012), and their GM increased relative to other crops (Ozpinar and Ozpinar, 2011). Positive effects of combined reduced tillage and legume rotations have also been shown in Germany, and lead to cost savings of 21% compared to a ploughed cereal-dominated rotation, whereas savings with reduced tillage and cereal dominated rotations were lower (Luetke-Entrup et al, 2006).…”
