Abstract
The Ministry of Agriculture and Soil Reclamation (MASR) in Egypt is actively pursuing the sustainable expansion of oil crops, particularly through the cultivation of canola to shrank gap and decrease the import gap for various oil products and edible oils. Therefor, a field trials were executed to assess the potential impact of different soil additions, including a control group without soil additions (T1), magnesium sulphate at a rate of 30 Kg Mg fed-1 (T2), plant residues compost (rice straw + soybean stover) at a rate of 7.0 tons fed-1 (T3), and a combined treatment of compost at a rate of 3.0 tons fed-1 plus magnesium sulphate at a rate of 15 Kg Mg fed-1 (T4) as the main plots on canola plants. Subplots were also designated for foliar applications of beneficial elements, comprising four groups: F1 (control), F2 (Magnesium sulphate), F3 (Zn-EDTA), and F4 (Fe-EDTA) at a rate of 500 g per feddan for each beneficial element. Various parameters such as plant height (cm) No. of branches plant-1, chlorophyll (SPAD reading), seed yield (ton.ha-1), straw yield (ton.ha-1), oil (%), oil yield (ton ha-1), protein (%) and carbohydrates (%) were recorded during the trials. The combined treatment (T4) emerged as the most effective soil addition, demonstrating optimal performance. Following closely in effectiveness was the use of compost alone (T3), with magnesium sulphate (T2) ranking third. In contrast, the control group, which did not receive compost and magnesium sulphate , exhibited the lowest performance among the treatments. As for foliar application treatments, the descending ranking order were: F2 (Mg element) < F3 (Zn element) <F4 (Fe element), <F1 (without beneficial elements). Prefely, the combined treatment of T4 x F2 emerged as the most superior among the various interactions studied. These findings underscore the importance of tailored soil amendments and foliar applications to maximize canola crop yields, providing valuable insights for the Ministry's strategic planning. Recommendations include widespread adoption of the T4 x F2 combination, further research on optimal dosage and application methods, and ongoing support for farmers in implementing these practices to bolster Egypt's self-sufficiency in oil production.
