“…Regarding titratable acidity (TA) and pH of fruits, there was interaction between the applied irrigation depth and the production cycles, with no difference between phenological stages (Figure 5). The soluble solids (SS) content and titratable acidity (TA) were higher in the first cycle, which can be explained by the lower number of fruits produced, causing greater leaf area per fruit and fewer sinks for the synthesized photoassimilates, such as sugars and organic acids, as observed in 'Palmer' mango by Oliveira et al (2019) and Simões et al (2020b). Fruit pH showed an inverse behavior to that of titratable acidity, which was already expected, because the pH is an inverse logarithmic scale of the concentration of H + and H 3 O + ions.…”

Brazil is the seventh largest producer of mangoes in the world, and the São Francisco Valley is the main producing region, with ‘Kent’ as one of the main cultivars. Considering that irrigation management affects physiological events, production and fruit quality, the objective of this work was to evaluate the gas exchange in the leaves and fruit quality of ‘Kent’ mango subjected to controlled water deficit in the semi-arid region. The experiment was carried out in Petrolina-PE, semi-arid region of the São Francisco Valley. The experimental design used was randomized blocks, in a triple factorial scheme, with four irrigation depths (40, 60, 80 and 100% of crop evapotranspiration - ETc), three phenological stages (F1 - flowering, F2 - fruit growth, F3 - fruit maturation) and two production cycles (2018 and 2019), with four replicates. During the phenological stages, the physiological parameters of gas exchange were evaluated. After harvesting, the following parameters were evaluated: soluble solids content, titratable acidity, pH, firmness and peel color. Irrigation with a depth between 79.5 and 83.6% ETc during the evaluated stages promoted greater gas exchange in the leaves, greater firmness and acidity in the fruits. The reduction in irrigation depth in F1 and F3 reduced the soluble solids content, while in F2 the highest soluble solids content was obtained with irrigation between 68.24 and 74.5% ETc. The most suitable irrigation depth for ‘Kent’ mango cultivation depends on the purpose of the producer and on the phenological stage of the crop.

“…Variations in the number of AMF spores were also observed in studies with agricultural soils of the caatinga under the influence of factors such as: plant species, seasonality (dry/rainy period), and type of management (conventional or conservationist) (LIMA et al, 2007;SANTOS et al, 2013;SOUSA et al, 2014;CARDOZO JUNIOR et al, 2018). The production of spores can be stimulated by stress situations, such as water deficit, temperature increase, soil disturbance, end of the growth cycle of annual plants or the productive cycle of perennial plants, and the high concentration of chemical substances, such as fertilizers, biocides, and plant metabolism regulators (SMITH & READ, 2008;BRUNDRETT & TEDERSOO, 2018;SALOMON et al, 2022).…”

“…The establishment of irrigation projects in the Sub-middle São Francisco Valley regularized water availability for agricultural areas and enabled implementing the fruit growing pole, which has contributed to strengthening and expanding agriculture in the Brazilian semi-arid region (SIMÕES et al, 2020). Sustainable technologies and innovations can contribute to increased productivity and product quality (BALOTA, 2017;OLIVEIRA & LIMA, 2021;.…”

“…Mango is one of the fruits produced in the fruit growing center of the Sub-middle São Francisco Valley (in Petrolina, PE and Juazeiro, BA), being most exported in terms of value and volume by Brazil, having a large share in the country's agriculture, as it produces from about 85% of the total exported in 2019. Thus, mango cultivation in the semi-arid region stands out nationally due to the large extension of cultivated area, production volume and fruit quality, with economic and social impacts in the region (SIMÕES et al, 2020;OLIVEIRA & LIMA, 2021).…”

Arbuscular mycorrhizal fungi (AMF) increase the absorption surface of roots, providing greater absorption of water and nutrients from the soil by plants. Thus, it is important to know how arbuscular mycorrhizae are affected by factors such as phenology, management and varieties in mango (Mangifera indica) orchards in the irrigated semi-arid region. With this objective, soil and root samples were collected during the vegetative, flowering and fruiting stages, and in the water stress period before flowering, always on the same trees. The study was carried out in mango orchards of the Keitt and Palmer varieties, in agricultural farms located in Juazeiro - BA and Petrolina - PE, both under conventional management (with fertilizers and paclobutazol). The soil was used to quantify the number of AMF spores and phosphorus content. Mycorrhizal colonization in roots was evaluated in qualitative terms (presence of hyphae, vesicles and arbuscles) and quantitative terms (% of colonization). Total mycorrhizal colonization was high, with averages above 65%, and higher values in the fruiting period. Colonization by vesicles and arbuscles was on average above 45% and 17%, respectively, with higher means also during fruiting. The number of AMF spores in the soil averaged over 130 spores in 50 g of soil, with higher values in the period of water stress. The phosphorus content in the soil did not influence mycorrhizal colonization and the number of spores in the soil. The association of AMF with mango trees was generally affected by management and phenology, regardless of the cultivated varieties.

“…Different responses to PBZ application are obtained in mango crop because there are many commercially grown varieties. Therefore, studies are needed for each form of cultivation of varieties, especially the type of irrigation system, as it affects the water absorption capacity of the crop (Simões et al, 2020), in producing regions, to obtain a better economic return with the practice of floral induction (Mouco, 2015).…”

Plant growth regulator on micro-sprinkler for mango `Palmer’ floral induction in Brazilian Semiarid

Application of the plant growth regulator paclobutrazol (PBZ) to aid mango floral induction has been widely performed by mango producers. However, its application has been done manually, resulting in low uniformity of application and losses with labor. The objective of this study was to adjust the PBZ dose to be applied via micro-sprinkler system for floral induction, indicating an efficient management of ‘Palmer’ mango in the Brazilian semiarid. The experiment was conducted at Saúde Farm, located in Petrolina-PE, Brazil. The experimental design used was randomized blocks, with five doses of PBZ, applied via irrigation system (T1 - 0.56; T2 - 1.12; T3 -1.68; T4 - 2.24; and T5 - 2.80 g a.i. linear m-1 canopy) and a conventionally applied dose (T0 - 2.80 g a.i. linear m-1 of canopy, manually applied broadcast), with four replicates. The variables analyzed were: photosynthesis rate, stomatal conductance, transpiration, leaf temperature, number and length of panicles, number of fruits per plant, average fruit weight, yield, pulp firmness, titratable acidity and total soluble solids in the fruits. At the conventionally applied dose (2.8 g a.i. linear m-1 of canopy), PBZ application via micro-sprinkler irrigation system proved to be the most efficient way to reduce photosynthesis rate, stomatal conductance and transpiration. PBZ applied via micro-sprinkler irrigation system at a dose of 0.56 g a.i. linear m-1 of canopy promotes greater number of panicles and yield in ‘Palmer’ mango.
