In order to promote agroecological practices, this study compares two cropping
systems, i.e., intercropping versus sole cropping of a cereal - durum wheat (Triticum durum
Desf. ) and a nitrogen-fixing legume - faba bean (Vicia faba L.) on plant growth, Efficiency in
the use of rhizobial symbiosis (EURS), grain yield and phosphorus (P) and nitrogen (N)
accumulation in soil and plant. This study conducted during two cropping seasons in a field trial
in the region of Tizi Ouzou, Algeria, shows that shoot dry weight (SDW), nitrogen nutrition index
(NNI), phosphorus use efficiency (PUE), land use efficiency (LER), and grain yield were
significantly higher for intercropped than for the sole cropped wheat. Furthermore, there was a
considerable increase in soil P and N content across the two years of intercropping and sole
cropping compared to the unseeded weeded fallow. Intercropping, it is claimed, improves wheat
N nutrition by increasing the availability of soil-N for wheat. This increase might be due to
reduced interspecific competition between legumes and wheat plants than intraspecific
competition between wheat plants due to the legume’s ability to compensate by atmospheric
nitrogen fixation.
