Abstract
This study was conducted in University of Duhok's nursery of horticulture department, college of Agriculture Engineering Sciences, in Kurdistan region of Iraq, during growing season (2022–2023). One-year-old almond seedlings were getting from college nursery. and sprayed two times: first spray was on 1^st April and second spray was on 1^st May. Randomized complete block design (RCBD) as factorial experiment was used, including three factors (Full green fertilizer (0, 4, 8) gm. L^{- 1}, GA3 (0, 50, 100) mg. L^{- 1}, and NAA (0, 750, 1250) mg. L^{- 1} (333*3), with three seedlings for each experiment unit. Statistical analysis was performed by SAS program Results were compared according to Duncan's multiple range tests at 5%. Results showed that full green significantly increased (stem length (90.11cm), shoot number (9.22), leave area (47.48 cm²), shoot dry weight (5.58gm)) at 8 mg/L^-1, GA3 significantly affected on (stem length (89.11cm), leave area (47.08cm²), shoot fresh weight (9.05gm), shoot dry weight (5.92gm) , root fresh weight (6.50gm), and root dry weight (3.85gm)) at 100mg/L^-1 ,and NAA increased stem length (90.85cm) and shoot fresh weight (8.73gm) at 1250mg/L-1, while shoot number (9.59) and leave area (46.12cm²) at 750mg/L^-1 NAA.
