Table 1. Aboveground biomass, its N and P and root infection by AM fungi at tillering of durum wheat grown in the field.

	Aboveground biomass	N content	N uptake	P content	P uptake
	Mg ha–1	mg N g–1 biomass	kg N ha–1	mg P g–1 biomass	kg P ha–1
NAT	1.52±0.177	18.78±0.970	28.39±2.441	3.60±0.117	5.40±0.260
AMF	1.85±0.240	16.88±0.383	31.30±4.176	3.37±0.173	6.17±0.733
AMF+PGPR	1.89±0.223	17.78±0.868	34.25±5.574	3.25±0.075	6.17±0.793
P-value	0.106	0.236	0.253	0.153	0.525

NAT = wheat with natural arbuscular mycorrhizal inoculum; AMF = wheat inoculated with spores of AM fungi; AMF+PGPR = wheat inoculated with both spores of AM fungi and plant growth—promoting rhizobacteria.
