Figure 5.
Influence of soil amendment with compost and plant growth-promoting rhizobacteria (PGPR) on the grain yield traits (A) grain spike−1, (B) 1000 grain weight, (C) grain yield, and (D) biological yield and harvest index (HI) of wheat plants grown in salt-affected soil and deficit irrigation in contrast to well irrigation. The error bars present the values of standard deviation. According to Duncan’s multiple range test, the same lower-case letters above columns are not significantly different (p < 0.05), while the upper-case letters in figure (D) presented the significant differences between means of HI.
