“…It is emphasized that Bhattacherjee and Singh (2015) applied the PBZ in a soil drench in a radial diameter of 1 m from the tree trunk (conventional application), which is significantly less effective than the fertigation used in the present study (Souza et al, 2018). Silva et al (2017) evaluated soil PBZ concentrations using the same method of the present study ('QuEChERS' and determination by HPLC) and found average values varying from 0.14 to 6.86 mg kg -1 in soils with different mango cultivars, finding that 'Keitt' orchards presented concentrations from 1.49 to 0.18 mg kg -1 at 150 DAP, which are higher values than the present study (Figure 3).…”

This study evaluated the impact of fulvic acid and free amino acids on paclobutrazol soil residue, their absorption and effects on ‘Keitt’ mango grown in tropical semi-arid environmental conditions. The experiment was carried out from 2017 to 2018 simultaneously in two orchards with the same plants and management characteristics, located in Cabrobó, Pernambuco, Brazil. The experimental design was randomized blocks with four treatments, five replications and four plants per replication. The treatments consisted of paclobutrazol combinations with acid fulvic and free amino acids, as follows: Treatment 1: paclobutrazol + water (control); Treatment 2: paclobutrazol + fulvic acids; Treatment 3: paclobutrazol + free amino acids; and Treatment 4: paclobutrazol + fulvic acids + free amino acids. According to the results, the use of fulvic acids, free amino acids or both affects the paclobutrazol absorption by 'Keitt' mango. The addition of fulvic acid to the paclobutrazol improves the absorption of this molecule by the plant, with greater inhibition of vegetative growth of 'Keitt' mango and lower soil residues.

“…In a study with application of PBZ in 'Bourbon' and 'Rosa' mangoes, flowering uniformity and a higher yield than for 'Palmer' mango were observed with the same application management (Chatzivagiannis et al 2014). Furthermore, the responses to the plant growth inhibitor application may vary with the nutritional status of the plant (Souza et al 2018).…”

“…Mango flowering may take over several months; thus, the beginning of flowering can be induced by environmental factors, mainly by temperature change, as well as management practices such as the use of growth regulator, pruning and irrigation (Oliveira et al 2017, Souza et al 2018, Oliveira 2020, Santiago et al 2020). These methods are especially important when it comes to organic agriculture, where synthetic products are disregarded.…”

The artificial flowering induction in mango tree is the most important crop management in mango orchards and requires greater attention from growers. The management involves three steps: stoppage of plant growth, branch maturation and flowering induction with nitrates. The first stage starts with the application of paclobutrazol to the soil. However, problems with the use of excessive concentrations are common and lead to the accumulation of residues in the soil. In addition, the use of paclobutrazol is not allowed in organic agriculture. Therefore, this review article aimed to compile information about the updates and efforts to solve these problems in conventional mango crops, as well as identify alternatives for its organic management. In conventional orchards, the application of fulvic acids in association with paclobutrazol, as an alternative to the single use of paclobutrazol, was identified as a way to improve the absorption of the product by plants and, consequently, reduce the concentrations and residues in the soil. Researches involving pruning, girdling, fertilization and irrigation should be developed as an alternative to the use of paclobutrazol for the organic crop system of mango cultivars in tropical and subtropical regions.

“…In 2019, there was a record shipment, in terms of both volume, with about 221,913 thousand tons, a 30% increase compared to the previous year, and revenue, more than US$ 227 million (ANUÁRIO, 2020). Mango cultivation in semi-arid regions is one of the main options for irrigated areas and the São Francisco Valley is one of the largest producers and exporters of this fruit, competing with its products in the international market (SOUZA et al, 2018). In the São Francisco Valley, in 2019 alone, there was a 25% growth in the cultivated area, according to a survey performed by the Center for Advanced Studies in Applied Economics (ANUÁRIO, 2020).…”

Plant regulators on the growth, quality and production of ‘Tommy Atkins’ mango fruits

The objective of this study was to evaluate the effect of cytokinin (BAP) and gibberellin (GA3) applications on the growth, physicochemical characteristics and production of ‘Tommy Atkins’ mango fruits. Mango plants were sprayed with five concentrations (0, 75, 150, 225 and 300 mg.L-1) of BAP and GA3 and BAP + GA3 (0, 75 + 75, 150 + 150, 225 + 225 and 300 + 300 mg.L-1) at 15, 30 and 45 days after anthesis (DAA), single applications of GA3 occurred at 60, 70 and 80 DAA. Fruits were evaluated weekly from 52 DAA for weight, diameter and length until harvest and characterized for soluble solids content and acidity. A higher peak of fruit growth occurred between 66 and 73 DAA. Application of 150 + 150 mg.L-1 (BAP + GA3) promoted at the end of the evaluation period higher fruit weight compared to the other treatments and the control. No significant differences were observed in fruit production, but also concentrations of 150 + 150 mg.L-1 BAP + GA3 led to more than 50% of fruits in the marketing standard type 8. Exogenous application of 150 + 150 mg.L-1 (BAP + GA3) at 15, 30 and 45 DAA increased the weight, diameter, length, acidity and the percentage of fruits type 8 of ‘Tommy Atkins’ mango, but it did not increase yield.
