Abstract

The possibility of canola achieving self-sufficiency in oil production in Egypt is feasible due to its adaptability to different climates and potential for cultivation in the country. With proper investment in research, infrastructure, and agricultural practices, Egypt can increase canola production and reduce its dependence on imported oils. So, two field trials were carried out during sequential winter seasons of 2021/2022 and 2022/2023 aiming to study the influence of four rates of elemental sulfur (ES) soil applications as main plots [control (ES0), 100, 150 and 200 kg S fed-1] and five micronutrient treatments as foliar application [control (without spraying), boron (B), zinc (Zn), iron (Fe) and mixture of them] as sub-plots on growth, yield and its components of canola plants. The values of available N, P, K, S and pH were measured in the experimental soil after harvest. The results of the study demonstrated that increasing the level of elemental sulfur fertilizer to 200 kg S fed-1 resulted in the highest vegetative growth values, effective yield, and its constituent parts compared to the control (ES0). Applying foliar treatment with a mixture of B, Zn, and Fe also had a significant positive effect on all growth parameters, yield, oil yield and protein yield. Moreover, the interaction between applying 200 kg S fed-1of elemental sulfur and foliar treatment with the mixture of B, Zn, and Fe caused the highest values for canola plant development, yield, and its components. Additionally, the control treatment (ES0 x without spraying) led to the highest remaining N and K concentrations in the soil, while the applying 200 kg S fed-1of elemental sulfur without foliar treatment resulted in the highest remaining P and S concentrations.
