| Abstract | ||||
| A pot experiment was conducted in greenhouse and nursery at Ornamental Farm Faculty of Agriculture, Suez Canal University, Ismailia Governorate Egypt, during the two seasons of 2018 and 2019. The aim of this work is to study the effect of different treatments of Hyper feed Nano-fertilizer NPK (19:19:19) Nano-fertilizer rates (0, 1.5, 3.0, 4.5 g/L) added every 15 days with irrigation water drench on the pot with 400 m/L and monthly foliar application with Gibberellic acid (GA3) at (0, 100, 200 and 300 ppm) either alone or in combination from the 1st of May to the 1st of October on the vegetative growth and some chemical constituents of Codiaeum variegatum (L.) cv. Gold dust plants. The results showed that Nano-fertilizer plus GA3 was the most effective compound to improving all growth parameters of Codiaeum plants, followed by Nano-fertilizer, while GA3 was the second in order. Among Nano-fertilizer treatments, the highest level of Nano-fertilizer at 4.5 g/L was optimum for growth of Codiaeum plants. Nano-fertilization every 15 days with Hyper feed Nano-fertilizer NPK (19:19:19) at 4.5 g/l combined with foliar spray of both GA3 at 300 ppm resulted in the highest significant values for plant height, stem diameter, number of leaves/plant, leaf area and fresh and dry weights of plant, fresh and dry weights of leaves, stems and roots/plant. Data also showed that the previously mentioned combination resulted in the highest contents of N, P, K, Total carbohydrates, and Total chlorophyll in Codiaeum leaves. | ||||
