Alpha diversity index at 0–40-cm depth under sugarcane straw retention (SR) treatment compared to control (CK). Different letters indicate significant differences between samples (Tukey test, p < 0.05). Values are mean ± standard errors (n = 3). Treatment: CK SR. Depth: soil of depth in 0–10, 10–20, 20–30, 30–40 cm. Multivariate ANOVA for the effects of straw retention and soil depth on number of OTUs number, ACE index, Shannon index
^arepresent the level of significance at 0.05
