Table 2. Tobacco growth and disease incidence.

Treatments	Incidence of bacterial wilt (%)	Disease index	Plant height (cm)	Stem girth (cm)
Tobacco in degraded soils	85.48 ± 35.57 A	79.92 ± 34.26 A	97.23 ± 6.42 a	9.12 ± 0.44 a
Tobacco in healthy soils	0 ± 0 B	0 ± 0 B	110.65 ± 8.36 b	9.8 ± 0.23 b

Values are means (n = 5) ± standard error. Different lower-case letters within columns indicate significant differences (P < 0.05), and different upper-case letters within columns indicate very significant differences (P < 0.01).
