Plant growth parameters of tomatoes (Solanum lycopersicum) according to companion planting ratio with sunflower (Helianthus annuus) in green roofs at 88 days after planting.

Treatments	Plant height (cm)	Stem diameter (cm)	Number of leaves	Leaf shape index
T alone	80.33 ± 0.90c	17.71 ± 0.38bc	418.78 ± 9.06b	1.76 ± 0.03a
T1S1	105.55 ± 0.83a	14.75 ± 0.17c	326.44 ± 2.31c	1.68 ± 0.02a
T2S1	86.44 ± 0.68bc	20.67 ± 0.14ab	320.89 ± 3.35c	1.57 ± 0.02a
T3S1	92.89 ± 0.95b	23.50 ± 0.71a	673.33 ± 5.74a	1.68 ± 0.02a

T alone, tomatoes; T1S1, tomatoes : sunflower = 1 : 1; T2S1, tomatoes : sunflower = 2 : 1; T3S1, tomatoes : sunflower = 3 : 1. Data are means ± SE. The same letters are not significantly different within the same column according to Duncan’s multiple range test at (n = 9). Leaf shape index is leaf length/leaf width.
