Abstract: A field experiment was conducted at the Agricultural Research Station affiliated with the College of Agriculture, University of Basrah, located in Karma Ali, Basrah Governorate, during the winter season of 2023/2024. The soil at the site was of loamy texture. The objective of the study was to investigate the effect of nitrogen fertilization and cutting frequency on the green and dry forage yield of triticale (X Triticosecale spp.). The experiment was applied using a factorial experiment approach within a Randomized Complete Block Design (RCBD) with three replications. The factorial treatments were randomly distributed within each block, resulting in a total of 18 experimental units (3 nitrogen levels × 2 cutting frequencies × 3 replications).The experiment included two factors: The first factor was nitrogen fertilizer at three levels: 100, 150, and 200 kg N ha⁻¹, denoted as N1, N2, and N3 respectively. The second factor was cutting frequency: one cut and two cuts, denoted as C1 and C2 respectively. Key findings: The highest nitrogen level (N3) showed a significant superiority in all studied traits, achieving the highest averages for plant height (104.50 cm), number of tillers (563.20 tillers m⁻²), green and dry forage yields (20.25 and 6.67 tons ha⁻¹ respectively), and nitrogen use efficiency (80.70%).Regarding cutting frequency, the single cut treatment (C1) was significantly superior in plant height and number of tillers, with averages of 102.44 cm and 546.90 tillers m⁻², respectively. However, the two-cut treatment (C2) showed superiority in the remaining studied traits.
