Zinc and boron foliar application, An influential treatment on the quality and seed yield of soybean
2024
Murshed, Fadi
The objective of this study was to investigate the impact of zinc and boron foliar treatment on some yield components of soybean. For that purpose, a field experiment was conducted in the northeastern region of Homs, Syria during the agricultural season of 2021-2022. The experimental plots were designated based on a randomized block design, consisting of four treatments and three replications. The treatment included a control (Zn0B0) without zinc or boron application; zinc-only application at 2 g/l (Zn2B0); boron-only application at 2 g/l (Zn0B2); and combined application of zinc and boron at 2 g/l each (Zn2B2). The foliar spray was applied once during the flowering stage. The number of pods per plant, the weight of pods per plant, seed yield, and protein content in seeds were investigated. The findings demonstrated that the combined application of boron and zinc through foliar spraying (Zn2B2), exhibited superior results in enhancing all the studied parameters. The seed yield under zinc and boron combined treatment exceeded that of the control by more than 50%. Therefore, the current results highlight the importance of these two micronutrients in soybean production.
