Abstract A field experiment was conducted during the 2022-2023 and 2023-2024 seasons in the experimental field of Al-Mahnawiyah demonstration farm affiliated with the Extension Training Center in Babylon province, 8 km north of Hillah and located within 11° north latitude and 11° east longitude, on loam silty clay soil. The experiment aimed to find solutions to the problem of green fodder scarcity during critical periods. A randomized complete block design (RCBD) was used, with a split-split plot arrangement and three replicates. The planting dates (10th, 20th, and 30th of September, respectively) represented the main plots, symbolized by D1, D2, and D3, respectively. The subplots were occupied by winter forage crops: barley (Buhouth 244), oats (Oat 11), Tartekili). cultivar (Amal), respectively and symbolized by (T3, T2, T1) respectively, while the sub-plot occupied the cutting dates: which are in (40 days, 50 days and 60 days) starting from after emergence and symbolized by (C3, C2, C1) respectively, and the area of the experimental unit was (2×2 = 4 m2). The results showed that: The first planting date (D1) in the second season only had a significantly excelled in green feed yield and dry matter yield, yielding 24.04 ton.ha −1 and 3.68 ton.ha −1 , respectively. While it significantly affected the traits (stem diameter, green feed yield, and dry matter yield) for the first season, recording (4.097) mm for the combination (D2T2C3) and (37.02) ton.ha −1 for the combination (D3T2C2). (4.855) ton.ha −1 for the combination (D3T2C3) respectively.
