Response of Gerbera (Gerbera jamesonii) to different levels of Phosphorus and Potassium
Abstract
Effect of phosphorus and potassium on growth and flowering of Gerbera (Gerbera Jamesonni)” was investigated at Horticulture farm, the Agricultural University Peshawar during 2011. The experiment was laid out in Randomized Complete Block Design (RCBD) with two factors and repeated thrice. Phosphorus levels (0, 7.5, 10 and 12.5 g m-2) and potassium levels (0, 10, 12.5, 15 g m-2) were applied to Gerbera. More plant height (31.72 cm), number of leaves plant-1 (29.76), flowers blooming period (183.18), plant canopy (33.59 cm), number of flowers plant-1 (16.63), flower stalk length (25.37 cm), flower diameter (8.05 cm) and vase life (7.32) were recorded in plants received 12.5g phosphorus m-2, while more days to first flowering (85.50) were noted in the control treatment. The findings further revealed that more plant height (30.04 cm), number of leaves plant-1 (28.08), flowers bloom period (182.05), plant canopy (31.00 cm), number of flowers plant-1 (15.68), flower stalk length (22.87 cm), flower diameter (7.30 cm) and vase life (7.00 days) were noted in plants treated with 15 K2O g m-2, while days to first flowering (88.00) were noted in control plots. As the interaction between phosphorus and potassium are concerned, most growth and flowering attributes performed best when treated with 12.5 g P and 15 g K2O m-2. It is concluded that the combination of 12.5 g P m-2 and 15 g K2O m-2 influenced most of growth and flowering parameters of Gerbera.
