In order to sustain canola production as an oil seed crop, two separated filed experiments were performed in the sandy experimental farm, faculty of Agriculture, Zagazig University, Egypt during the two successive winter seasons of 2022/23 and 2023/24. Four nitrogen fertilizer levels (30, 60, 90 and 120 kg N/fad) were experimented, once under sprinkler irrigation system and another under drip irrigation system using Randomized Complete Block Design (RCBD) in three replicates. The study aimed at optimizing the nitrogen dose for maximized yield and quality of canola crop, in addition to comparing between the behavior of canola plants under both the irrigation systems. Results showed significant differences in growth traits, yield components, seed and oil yields as well as weeds distribution due to varied nitrogen levels. 90 and 120 kg N/fad achieved the same level of significance maximizing all traits under study including the highest seed and oil yields, so it is recommended to fertilize canola by 90 kg N/fad. Additionally, drip irrigation showed superiority in all studied traits over sprinkler system recording 8% over seed yield and conserving 16.75% water in both seasons; in addition to the efficacy of drip irrigation in limiting weed coverlet. Thus, it is recommended to grow canola in sandy soil under drip irrigation fertilized by 90 kg N/fad.
