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.
