Abstract: The study was conducted in three consecutive agricultural seasons, (2020 - 2021), (2021 - 2022), and (2022 - 2023), in three locations in Nineveh Governorate: - First location was in east of Mosul / Bashiqa district / Tobzawa village, which is 25 km far away from the center of Mosul; Second location was in west of Mosul in Hamidat district / Althalja village, which is far 15 km from The center of Mosul city, and the third location was in the village of Alshuhada, which is located northwest of the city of Mosul, which is 35 km away from the center of Mosul city. All locations are considered within areas, that are semi-guaranteed rain regions. The experiment included nine treatment combinations that represented the combinations between three sites and three levels of previous agriculture. All experiments applied according to the split-plot system, were designed in a completely randomized block design with three replicates, where the sites being occupied by the main plots and the previous cultivation being the secondary plots. The important results are summarized as follows: The first cultivation system achieved the highest values for all growth traits, feed and grain yield, and protein percentage, while the lowest values for most of the traits studied were in the third cultivation system. The highest values were achieved for most of the studied traits in the first site (Tobzawa), and the lowest values were for most of the studied traits in the third site (Alshuhada).
