Table 5.

Variations in nitrogen and protein contents of durum wheat fertilized with rock P in response to inoculation with five PSB isolates versus P (RP and TSP) treatments alone.

	N (mg∙g⁻¹)	NUE (g²∙mg⁻¹)	Prot (mg∙g⁻¹ FM)
RP	32.25^b	0.08^b	1.84^d
TSP	42.14^a	0.07^b	4.8^a
PSB₁ + RP	33.79^b	0.11^a	2.02^d
PSB₂ + RP	38.08^ab	0.06^b	4.31^b
PSB₃ + RP	34.95^b	0.14^a	4.26^b
PSB₄ + RP	37.99^ab	0.08^b	2.59^c
PSB₅ + RP	33.02^b	0.12^a	2.9^c

Data are means of four replicates (each replicate consists of eight wheat plants per pot) harvested at 42 days after germination. Mean values labeled with the same superscript letter were not significantly different at p < 0.05. N, Nitrogen content; NUE, Nitrogen use efficiency; Prot, Protein content.
