A field experiment was conducted to determine the response of different doses of N and P2O5 on the growth and flower quality of gladiolus at farmer field district Quetta during the summer season 2008. Six treatments were included in the trial viz. T1 (125+100); T2 (125+200); T3 (150+100); T4 (150+200); T5 (175+100) and T6 (175+200) NP kg/ha were tested in four replicated randomized complete block design. The results reveal that fertilizer treatments had significant response on leaves length, leaves number, florets number per spike, corms number per plant, corm lets number per corm and spike length. The highest N and P2O5 dose 175+200 kg/ha produced significantly maximum length of leaves (44.4 cm), greater number of leaves (13.75), number of florets per spike (14.00), number of corms per plant (4.00), number of cormlets per corm (18.62) and longer spike length (99.75cm). It was concluded that for obtaining maximum number of florets per spike, number of corms per plant, number of corm lets per corm and longer spike length application of nitrogen and phosphorus at 175+200 kg/ha may be applied.
