Fig. 2From: Biochar-amended potting medium reduces the susceptibility of rice to root-knot nematode infectionsEffects of biochar amendments on plant growth and nematode infectivity in rice roots. a Root galls and nematodes per gram root in biochar-amended (different concentrations) and non-amended rice roots were counted at 14 dpi. b Plant height and fresh weight were measured at 14 dpi. c Root galls per plant on the 1.2 % biochar-amended and non-amended rice roots were counted at 14 dpi. d Nematodes per root in different developmental stages in the 1.2 % biochar-amended and non-amended rice roots were counted at 14 dpi. The bars in the different graphs represent the mean ± SE of the data from three independent biological replicates, each containing 6 individual plants. Different letters indicate statistically significant differences (Duncan’s multiple range test at p ≤ 0.05)Back to article page
