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 1st April and second spray was on 1st 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 (3*3*3*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.
