Abstract:
To evaluate the effect of intercropping maize and fibre sorghum with faba bean, compared to monocrop cultivation, on yields (dry matter, grain yield and N uptake) as well as on nitrogen utilization efficiency (NUtE) and N fertilizer recovery fraction, a field experiment was carried out in central Greece, on a fertile, clayey to loamy textured soil, classified as Vertisol. Four dressings of N-application were combined with either incorporating or harvesting the cover crop. The recovery fraction in maize was affected by faba bean incorporation slightly (by 10%), but in the case of sorghum it escalated from 40% in the control plots to 80% in the plots with previous faba bean cultivation. Corn seed yield fluctuated from 7.4 to 10.25 t/ha for the control plots, and from 8.3 to 12.5 t/ha when faba bean was incorporated. Semblably, sorghum total dry biomass fluctuated from 23 to 27 t/ha for the control plots, from 225.2 to 30.9 t/ha when faba bean was harvested and from 26.3 to 32.5 t/ha when incorporated. The NUtE was about 47 kg/kg and 72 kg/kg for maize and sorghum, respectively.
