An experiment was conducted to study the response of zinnia cultivars to phosphorus levels at Ornamental Nursery, Department of Horticulture, University of Agriculture, Peshawar. The experiment was designed as Randomized Complete Block Design with split plot arrangement having three replications. Phosphorus levels (0, 100 kg ha-1, 200 kg ha-1 and 300 kg ha-1) were subjected to main plot and zinnia cultivars (Dreamland Red, Yellow, Pink and White) were kept in sub plots. The results of statistical analysis revealed that both phosphorus levels and cultivars showed significantly different response in all the growth parameters. Highest survival %(100%), flower number (22.61) plant-1, flower diameter (9.09 cm), fresh flower weight (10.58 g), plant height (43.86 cm), fresh root weight (4.88 g), root length (18.73 cm) and less days to initiate flower (40.92) were observed in plots, supplied with phosphorus at the rate of 200 kg ha-1. Among cultivars Red cultivar showed maximum survival % (100%), plant height (46 cm), flower numbers plant-1 (21.21), fresh flower weight (12.28 g), flower diameter (9.25 cm), root weight (4.50 g), root length (17.21 cm) and minimum days to flowering (40.42). The interaction (phosphorus levels and cultivars) was non-significant in majority of parameters. Among different treatments used, zinnia cv. Red, treated with 200 kg P ha-1 should be recommended for maximum growth and flowering attributes under agro-climatic conditions of Peshawar.
