| Abstract | ||||
| In a factorial experiment, the influence of five potting media [sand, peat moss, vermiculite, peat moss + sand (1:1, vtv) and vermiculite + sand (1:1, v/v)] and three foliar fertilizer levels (1- spraying with tap water as control, 2- weekly spraying with solution contain 19m/liter of Solofert fertilizer (contain 20% N, 20% P20S, 20% K20 and 600 ppm Fe, 400 ppm Zn, 400 ppm Mn, 50 ppm Mg, 50 ppm Cu and 50 ppm 8), and 3- weekly spraying with solution contain 2gmlliter of the same fertilizer] on Epipremnum aureum growth and pot grade was evaluated. Foliar fertilization significantly enhanced pothos growth as: vine length, leaves No. /pot, arealleaf and leaves area/pot, shoot and root fresh and dry weight as well as plant quality (pot grade). This was associated with increasing N, P, K, and total carbohydrate percentages in leaves of fertilized plants. Generally, there were no significant differences between low and high fertilizer levels. Growing plants in peat moss + sand (1: 1. vlv) medium resulted. in the highest values represented growth, pot grade as well as leaf chemical composition comparing to all the other tested potting media. Interaction treatments between peat moss + sand (1: 1, v/v) medium and 1 or 2 gm fertilizer/liter levels showed the superior effect in enhancing pothos growth and quality. Correlation coefficients study under the effect of interaction treatments between the used foliar fertilizer levels and potting media recorded high positive significant correlations between percentages of N, P, K, and lotal carbohydrate in plant leaves and the studied vegetative characters. This was reflected positively on pot grade. | ||||
