Abstract: The present research work was conducted at National Agricultural Research Center Islamabad during 2015. The experiment was laid out on Randomized Complete Block Design (RCBD) with ten treatment and four replications having two factors. The first factor was fertigation (control, three Nitrogen levels (44, 64, 86 gram N/m2) and three humic acid levels (250, 350, 500 ppm humic acid/plant.) and three nitrogen and humic acid combinations (44 +250, 64+350, 86 gram N/m2 + 500 ppm Humic acid/plant respectively). The second factor was varieties (Megma Red, Yellow, Pink Rose Suprime and White Prosperity). Maximum number of florets per spike (11.68) in Megma red variety was recorded at 350ppm Humic Acid, while maximum plant height (43.98 cm) in pink rose suprime variety was recorded at 500ppm Humic Acid per plant.
