Figure 4: Data from Experiment 2 on (A) total above-ground biomass (g d wt per plant) of tomato subject to four treatments after four months of planting on two soil types, (B) fruit yield of tomato (g d wt per plant), (C) leaf chlorophyll concentration (SPAD unit) measured at 76 days after transplanting of tomato. (i) Cont: Non-fertilised, (ii) ACE: Aerated compost extract, (iii) NCE: Non-aerated compost extract (iv) Chem: Chemical fertilizer. Within a given soil type, means with different letters indicate significant difference (P < 0.05) and vertical bars represent the standard error of the mean (n = 6).
