Standardization of foliar nutrients (NPK) spray in anthurium cv. Flame

摘要

The present investigation was carried out at Green house Complex, Department of Floriculture and Landscape Architecture, ASPEE College of Horticulture and Forestry, Navsari during the year 2009-2010 under 75% shade net. The experiment was conducted with twelve levels of NPK @ 0.2% as foliar spray along with two levels of frequencies (weekly once and weekly twice spray). The treatments were repeated thrice in completely randomized design with factorial concept. Among all treatment combinations, overall best performance was recorded in weekly once foliar spray of NPK nutrients with ratio of 30:20:40 (F_7W_1), which significantly improved the spathe length (4.99 cm), spathe width (3.99 cm), flower stalk length (21.98 cm) and suckers per plant (2.93). While, F_6W_1 treatment (weekly once spray of NPK with 20:20:40 ratio) resulted maximum flower longevity (46.83days) and vase-life (19.67 days). However, maximum number of flowers (4.99) was obtained with F_1W_1 and which was at par with F_7W_1treatment,where 4.94 flowers per plant were recorded.
