3.5 Oil and protein content
The effect of water deficit stress on oil and protein content in
inoculated and no-inoculated plants with PGPB has been illustrated in
Fig 3. Based on obtained data from NIR, a negative correlation was
observed between oil and protein content in all of the treatments
(Fig4). Oil content was significantly lower under water stress but the
symbiotic association had no significant impact on it. The highest oil
content was recorded with 31.94% and 31.28% for control and B1D0
treatment respectively. Adversely, the highest protein content related
to B1D2 (27.16%), Also, PGPB treatment had a significant effect on the
enhancement of protein content (Fig4).
