Influence of phosphorus fertilization on gladiolus corm and flower production

The influence of different levels of phosphorus on corm and flower productivity of Gladiolus (Gladiolus grandiflorus) was studied at Faculty of Agriculture Rawalakot, Azad Jammu and Kashmir during the year 2010. Corms of similar size and weight were collected from Awan Nursery and Seed Store, Rawalpindi. Sowing was done on 25th April, 2010 with five different phosphorus levels viz. 40, 70, 100, 130, 160 kg ha-1. The experiment was laid out as RCBD (randomized complete block design). Maximum number of leaves (8.68), maximum plant height (156.0), minimum number of days to spike emergence (68.10), minimum number of days to flowering (72.74), maximum spike length (78.73), maximum number of cormels per plant (102.70), maximum weight of corm (67.33) and cormel (3.43), maximum size of corm (7.43) and cormel (2.06) was recorded for P5. Minimum number of days to sprouting (12.00) was recorded in P4. Maximum number of plants per corms, florets, spikes and corms per plant were recorded in P4 andP5.
