Abstract:
An experiment ‘Vegetative growth of gladiolus in response to phosphorus under the soil and climatic conditions of Peshawar’ was conducted at Agriculture Research Farm, Department of Horticulture, NWFP Agricultural University, Peshawar, during 2003-05. Eight cultivars of gladiolus namely Deciso, Hong Kong, Jessica, Jester Ruffled, Madonna, Peters Pears, Rose Supreme and White Friendship were subjected to phosphorus at the rate of 0, 100 and 200 kg ha-1. Years had a significant effect on all vegetative growth parameters. It was observed that sprouting, spike emergence, first florets and full spike opening were earlier in year-1(2003-04). Maximum number of plants per corm was observed in year-1. However, plant height was more in year-2 (2004- 05). Interaction (Year X phosphorus) significantly influenced plant height whereas plants emergence (sprouting), days to spike emergence, days to first floret and full spike opening were not affected significantly. Cultivars showed significant differences in all vegetative characteristics studied during the experiments. Interaction between years and cultivars significantly affected vegetative growth parameters. Phosphorus levels did not influence vegetative growth. The same was noted in interactions (phosphorus X cultivars, years X phosphorus levels X cultivars).
