Effect of sulfur, boron, zinc and iron on canola under salt affected soils [electronic resource]

Includes bibliographic reference

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-1 of 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-1 of elemental sulfur without foliar
treatment resulted in the highest remaining P and S concentrations.
