Abstract
In order to studying the influence of foliar spray with different NPK levels (0.0, 1.0, 1.5 and 2.0 g/ l) as main factor and tap water, dry yeast(Y)at 0.5g/ l, ascorbic acid (AA) at 150 ppm and 0.5g/ l Y+150 ppm AA as sub factor as well as their interaction treatments on Arabian jasminevar. Double petals, a pot experimental study was conducted during 2016 and 2017 seasons at Floriculture Unit of Hort. Dept., Fac. Agric., Mansoura Univ., Egypt. These treatments (4×4) were arranged in a split-plot design with three replications. The obtained results revealed that, NPK fertilization level at 2 g/ l significantly increased Arabian jasmine growth (plant height, branches and leaves number per plant, leaves fresh and dry weights per plant and total leaves area per plant), flowering parameters (flowers number per plant, flowers fresh weight per plant, flower diameter/ plant, flower stalk length and petals number per flower) and chemical constituents (chlorophyll a, b and a + b contents, total nitrogen %, total phosphorus % and potassium%) compared to the lowest levels under study and control (sprayed with tap water). Also, using 0.5 g/ l Y+150 ppm AA recorded the highest values of all measured parameters compared to the other treatments under study. In general, the results of this study suggested that foliar applications of 2 g/ l NPK could help enhance Arabian jasmine(Jasminum sambac Ait.) growth, flowering and total chlorophyll content when interacted with dry yeast at 0.5 g/ l + ascorbic acid at 150 ppm.
