The effect of relay intercropping between winter durum wheat sown at 33% and 100% densities and lentils on soil mycorrhizal inoculation potential (MIP), crop yield, and land equivalent ratio (LER) under a low input management system was investigated. The relay intercropping system significantly (P=0.017) influenced soil MIP. A clear trend and a higher soil MIP increase was recorded in the relayed system compared to the sole cropping system. At harvest, no significant (P=0.067) difference in lentil grain yield was observed between the sole and intercropped lentils, but a slight reduction in wheat grain yield: -17% and -14% in intercropped wheat at 33% and 100% density respectively. However, wheat yield reduction could be compensated by the high-valued lentil harvest, which averaged 1.24 and 0.77 t ha-1 for 33% and 100% density respectively. LER values for both relay systems were >1 indicating a yield advantage of the relay system in durum wheat-lentil production.

Abstract
The effect of relay intercropping between winter durum wheat sown at 33% and 100% densities and lentils on soil mycorrhizal inoculation potential (MIP), crop yield, and land equivalent ratio (LER) under a low input management system was investigated. The relay intercropping system significantly (P=0.017) influenced soil MIP. A clear trend and a higher soil MIP increase was recorded in the relayed system compared to the sole cropping system. At harvest, no significant (P=0.067) difference in lentil grain yield was observed between the sole and intercropped lentils, but a slight reduction in wheat grain yield: -17% and -14% in intercropped wheat at 33% and 100% density respectively. However, wheat yield reduction could be compensated by the high-valued lentil harvest, which averaged 1.24 and 0.77 t ha-1 for 33% and 100% density respectively. LER values for both relay systems were >1 indicating a yield advantage of the relay system in durum wheat-lentil production.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
