Abstract The experiment was conducted during the 2020-2019 agricultural season, at one of the agricultural fields of the Agricultural Extension Department, in Al-Muthanna Governorate, to study the effect of different levels of nitrogen fertilization and cultivars on green fodder yield, grain yield and oat crop components.The experiment included two factors, the first of which was four levels of fertilization (N0, N80, N160 and N240).The second factor was three cultivars of oats (Bohoth11, Jouda and Shefaa). The yield increase per unit area of feed, comes as a result of the development of agricultural technologies, as the use of appropriate quantities of nitrogen fertilizer, which improving plant growth, by entering mainly in the manufacture of proteins, amino acids and energy compounds (Hopkins, 1999). (2014) reported that when studying three genotypes of oats, V3 genotype was significant, as it recorded the highest averages in the quality of the number of leaves and the green fodder yield, it reached 5.41 leaves and plant 68.43 tons. ha-1. [...]it became necessary to search for other means or technologies, lead to an increase in the yield, as a study of the best amount of fertilizer with a number of cultivars, This study came with the aim of studying the effect of different levels of fertilizer treatments and cultivars on feed yield, grain yield and its components. The results also showed a significant effect of fertilization levels on the number of leaves per plant, as fertilization treatment N240 outperformed the rest of the experiment treatments by giving it the highest average for the first and second clipping, which reached 9.98 and 7.98, respectively, while the comparison treatment gave the lowest mean of 8.52 and 6.59 for the two clipping, respectively, this can be attributed to the role that nitrogen enters as a basis in physiological processes, such as photosynthesis, amino acid formation and green plastid formation, as well as encouraging the division, expansion and elongation of cells, which means the formation of new vegetative and root growth (Kocar and Albayrak 2012), The results also showed that there was significant interaction between factors in the second clipping only, the combination (V3xN240) gave the highest average of 8.50, this was due to what has been mentioned in the interpretation of the factors, which was alone. 4.Yield of green fodder (ton. ha-1): Table 5. showed that the varieties affected the yield of green fodder in the
