Seedlings of fruit crops grown in nurseries need fertilization, especially adding fertilizers that contain the nutritional elements that these seedlings need for the purpose of improving their growth, especially in terms of the diameter of the main stem to facilitate the Budding process. This study aimed to demonstrate the effect of two appointments (every 15 and 30 days). To add three concentrations of the liquid organic fertilizer Vivitar (0, 2, and 4 ml L^-1) and foliar spraying with three concentrations of the amino fertilizer Techamine Max (0, 2, and 4 ml L^-1) to improve some growth characteristics of Christi Thorn seedlings, a randomized block design was used. The complete (R.C.B.D.) designed the experiment that contained three factors, three replicates, and four seedlings for each experimental unit. The most important results obtained showed that the studied characteristics (total chlorophyll in leaves, increase in seedling diameter, and fresh and dry weights) increased significantly when foliar spraying with concentrations of the amino fertilizer (Tikamin Max), especially the concentration of 4 ml L^-1, while two additional treatments achieved Liquid organic fertilizer (Vivitar) 2 and 4 ml L^-1 had the highest increase in the two traits (total chlorophyll in leaves and increase in seedling diameter), while the timings of adding fertilizers (every 15 and 30 days) did not have any significant effect on the traits except through a superior date. Addition (every 15 days) over the time of addition (every 30 days) had a significant effect on the percentage of dry matter in the leaves.
