Abstract

Effect of different nitrogen levels on the growth of Chrysanthemum cultivars” was determined at Horticulture farm, The University of Agriculture, Peshawar during spring 2014. The experiment was laid out in Randomized Complete Block Design (RCBD) having split plot arrangement with three replications. Four levels of nitrogen (0, 50, 100 and 150 kg ha-1) and four cultivars of Chrysanthemum (Candy Floss, Lillian Jackson, Elizabeth Lawson and Harry Revill) were used during the study. Both cultivars and nitrogen levels were significantly different among most of the growth parameters. Among nitrogen levels, the maximum number of days to sprouting of lateral shoot (20.89) was observed in control treatment. Maximum growth rate week-1 (4.88 cm), number of lateral shoots plant-1 (43.73), number of leaves plant-1 (205.96), leaf area (17.35 cm2), number of roots plant-1 (55.07), root length (15.63 cm) and root diameter (4.87 mm) was recorded at 150 kg N ha-1. In case of cultivars, maximum number of days to sprouting of lateral shoot (19.94) was recorded in cultivar Candy Floss. The maximum growth rate week-1 (5.09 cm), number of lateral shoots plant-1(42.62), number of leaves plant-1 (192.71), leaf area (17.15 cm2), number of roots plant-1 (52.74), root length (16.05 cm) and root diameter (5.04 mm) was observed in cultivar Elizabeth Lawson. It was concluded that the best performance were recorded at 150 kg N ha-1 in cultivar Elizabeth Lawson. Hence cultivar Elizabeth Lawson is recommended to be grown for good growth at 150 kg N ha-1 in Peshawar region.
