| Abstract | ||||
| An experiment was carried out during the two seasons of 2021 and 2022 at the Tropical Farm, Kom- Ombo, ARC, Aswan Governorate, Egypt to study the performance of one year old Chrysophylum oliviforme seedlings under different growing media and chemical fertilizer NPK treatments. The rates of NPK were 0, N12:P10:K5 and N24:P20:K10 g/ seedling, while the applied growing media were clay, sand, clay: sand (1:1 v/v) and peat moss. The experiment was arranged in a split-plot as randomized complete block design (RCBD) with three replicates. NPK fertilizer levels as main plots, while the four growing media as sub-plots. Results observed that the addition of NPK fertilizer in different media caused increase of all studied traits i.e. shoot length, stem diameter, leaves number/ seedling, shoot fresh and dry weight of seedling, root fresh and dry weight and leaf area index in the two seasons. The highest values of these parameters was recorded when NPK fertilizer was applied at the rate of N24P20K10. Planting C. oliviforme in peat moss, followed by in the mixture of clay: sand (1: 1 v/v) resulted in the highest values of the morphological features. Growing seedlings in peat moss + N24P20K10 increased the studied traits than the other combinations. Therefore, to obtain strong seedlings in the nursery stage for such slow- growing tree species at the beginning growth, they must be planted in a suitable media as peat moss or mixture of clay: sand (1:1 v/v) with addition of NPK at the rate of 24:20:10 g/ seedling. | ||||
