| Abstract | ||
| The experimental field was carried out at a Farm of Ghazala Village, Zagazig District, Faculty of Technology and Development (Sharkia Governorate) during 2017/2018 and 2018/2019 growing seasons to study the effect of planting density (5, 10 and 15 cm) and nitrogen fertilizer levels ( zero, 40, 60 and 80 Kg N / fad. ), on seed, straw yield and its components for three Canola varieties (Serw 4, Serw 6 and Pactol). The results showed that Pactol variety achieved higher values and significantly increased compared Serw 4, Serw 6 varieties in number of branches and straw yield. Also, the same trend was found in seed yield. Since Pactol variety was high significant gave the higher in seed yield and their components i.e., number of pods / plant, number of seeds / pod, 1000-seed weight (g) and seed yield ton / fad., protein and oil %. Highly significant differences were found among planting density (5, 10 and 15 cm), equal (335.838, 167.885 and 111.877plant / fad.), in seed and straw yields and its components. Whereas (15 cm ) planting density gave higher in characters in number of branches / plant, straw yield, number of pods / plant, 1000-seed weight (g), seed yield, protein and oil percentages. Increasing nitrogen levels from zero, 40, 60 and 80 kg N/ fad., increased significantly and high significant the studied characters. In general, 80 Kg N / fad., gave the highest values, followed by 60, 40 and zero (control) Kg N / fad., was lowest in the respect. Conclusively, the results indicated that, seed yield appeared positive and significant or highly significant correlation with number of seeds / pod, 1000-seed weight, straw yield, oil and protein percentage. | ||
