Comparative effects of the different growing media used on the morphological parameters and aerial biomass production for melon, tomato and lettuce seedlings.

GC: green compost, PF: palm fibre trunk wastes, SP: peat. H: total length; D: stem diameter; SPAD: values of foliar chlorophyll contents; NL: number of leaves; LA: area of leaves; LAI: leaf area index; FW: fresh weight of seedlings aerial part; DW: dry weight of seedlings aerial part. Mean values (n = 15) in rows followed by the same letter are not statistically different according to the Tukey test at P < 0.05.
