Abstract Adequate fertilizing management is crucial to reach high mango yields that demand a well-defined fertilizer management, including micronutrient such as boron which management is more difficult due to the narrow range between deficiency and toxicity. This way, an experiment was carried out to evaluate the fruit production and quality of mango cv. Palmer as a function of boron fertilizing management in Brazilian semiarid. The experimental design was in randomized blocks with six treatments (strategies for boron fertilizing), as follows: T1 = five sprays with H3BO3 (two first at 0.3% and three at 0.2%); T2 = five sprays with H3BO3 (two first at 0.3% and three at 0.4%); T3 = five sprays with H3BO3 (two first at 0.3% and three at 0.6%); T4 = two sprays with H3BO3 at 0.3% + three fertigations with 10 g of H3BO3 plant-1; T5 = two sprays with H3BO3 at 0.3% + three fertigations with 20 g of H3BO3 plant-1; and T6 = two sprays with H3BO3 at 0.3% + three fertigations with 40 g of H3BO3 plant-1. Boron fertilizing management (foliar spray and fertigation) affects fruit production and quality of mango cv. ‘Palmer’ grown in semiarid. According to the minimum quality criteria required for mango fruit commercialization and the fruit production per plant in semiarid, five sprays with H3BO3 [two first at 0.3% and three at 0.2%] could be recommended.
