The planned mean comparison between the control and treated groups (Rest plots) showed highly significant improvements in all measured traits: treated plants had longer leaves (44.2 cm vs. 41.5 cm), wider leaves (13.5 mm vs. 13.1 mm), longer internodes (10.1 cm vs. 9.0 cm), and delayed flowering (94 days vs. 88 days), with significance levels ranging from (**) to (***).
