“…Similarly, little attention has been paid to S nutrition of legumes; it is generally not applied to faba beans as standard agricultural practice (AHDB, 2022 ; GRDC, 2017 ). Similarly, although yield benefits and increased nodule numbers have been reported following application of boron (B) fertilizer in combination with zinc (Zn) and molybdenum (Mo) (Adissie et al., 2020 ; Mohamad & Mohammed, 2020 ), there have been no attempts to optimize the rates of these micronutrients for BNF. Therefore, in addition to optimizing N, P, and K to local regions, future studies focusing on elucidating the roles of Mg, S, and macronutrients such as B and Mo in BNF and optimizing the application of these nutrients may also be beneficial.…”
