Abstract

The objective of this investigation was to study the effect of NPK fertilization (1000 or 2000 ppm at the formula of 2:1:1 with or without trace element) in addition to gibberellic acid (GA3) on vegetative growth and chlorophyll content of English Ivy plants. The results indicated that NPK fertilization at the rate of 1000 ppm with trace elements (Fe, Zn, and Mn 50 ppm)/ 2 weeks gave the best results. This treatment significantly increased the average plant height, stem diameter, number of leaves/ plant, fresh weight of foliage (stems and leaves), and leaf chlorophyll content. Also, NPK fertilization at the rate of 1000 ppm without trace elements/ 2 weeks increased the vegetative growth followed by NPK fertilization at the rate of 2000 ppm with trace elements/ 4 weeks, whereas, NPK at the rate of 2000 ppm without trace elements/ 4 weeks improved the vegetative growth as compared with the untreated plants. Spraying the plants with GA3 at the rate of 125 ppm / one month or 250 ppm/ 2 months encouraged the vegetative growth as compared to the untreated plants; GA3 at the rate of 125 ppm/ one month was the most effective treatment. The interaction between NPK fertilization with or without trace elements and GA3 showed that (NPK at 1000 ppm and trace elements at 50 ppm/ 2 weeks) treatment × GA3 at the rate of 125 ppm/ one month could be recommended for English Ivy plants.
