The study was carried out in the greenhouse of the Department of Forestry/College of Agriculture and Forestry/the University of Mosul for the period from 15/9/2020 to 15/8/2021 to study the effect of spraying with N.P.K nano and mineral fertilizer on some growth characteristics of Pinus brutia seedlings. The spraying process was carried out using two types of N.P.K nano fertilizer, the first is (20: 20: 20) and the second is (12:12:36), and N.P.K mineral fertilizer was used in two types, the first is (20: 20: 20) and the second is (12:12:36) at a concentration of 5 g. L-1 for both nano and mineral, and by four sprays (2 autumns + 2 spring). The results showed the superiority of nano fertilizer (20:20:20) over the rest of the treatments in terms of the increase in longitudinal and diagonal growth, root length and diameter, and the wet and dry weight of the vegetative mass, which amounted to 28.3167 cm, 3.8383 mm, 58.5333 cm, 5.52000 mm, 32.4703 g and 13.9210 g respectively. The mineral fertilizer (20:20:20) also showed significant superiority over all treatments as it gave 27.4833 cm, 3.5939 mm, 57.1778 cm, 5.26278 mm, 29.7901 g and 13.3387 for the studied traits, respectively, an increase in longitudinal and diagonal growth, root length, root diameter and wet and dry weight of the stem. The interaction between the two fertilizers N.P.K nano (20:20:20) and mineral N.P.K (20:20:20) was significantly superior by giving the highest average growth of all studied traits, as it gave 30,717 cm, 4.2680 mm, 61,000 cm, 5.8493 mm, 36.135 g and 15.8160, respectively.
