“…Although Ca is not mobile, the characteristic decrease observed between stages, especially in mature leaves, shows that, regardless of the treatment, this happens for phenological reasons, probably due to the translocation of calcium to the developing fruit and subsequent physiological fall of some fruits, causing nutritional loss (Rezende et al 2023).…”

Calcium (Ca) is a nutrient responsible for maintaining plant quality and fruit yield. The production of new Ca sources, such as micronized (CaM) and complexed Ca (CaC), and their supplementation provide a better yield in mango cultivation. This study aimed to evaluate the efect of Ca sources (micronized and complexed with Ascophyllum nodosum) and application methods on mango cultivation, in semi-arid Brazil. The experimental design was randomized blocks, in a 6 × 6 factorial scheme. The Ca supplementation strategies (control; 1 L ha−1 of CaM; 2 L ha−1 of CaM; 2 L ha−1 of CaC with A. nodosum extract; 2 L ha−1 of CaC with A. nodosum extract + application of 2.5 L ha−1 via CaC fertigation; and 2.5 L ha−1 via CaC fertigation) were evaluated on six dates regarding nutritional aspects. For biochemical and production aspects, the six supplementation strategies with Ca were evaluated. The Ca concentration in leaves and fruits signifcantly afected the interaction among the factors. The fertilization strategy with 2.5 L ha−1 of complexed calcium via fertigation was fundamental to provide increases in the nitrogen and Ca concentration of the fruits from 65 days after full fowering, and had positive efects on fruiting and production of mangoes cv. Kent.

“…Although the treatments had no effect, the levels are within the optimum range determined by Quaggio (1996) for mangoes (N-12.0 to 14.0 g•kg -1 ; Ca-20.0 to 35.0 g•kg -1 , and Mg -2.5 to 5.0 g•kg -1 ). However, for high-yield mango trees (Rezende et al, 2022), seedlings were deficient in N and supplied with Ca and Mg. It should be noted that despite comparing the nutrients using different authors' findings, the values refer to older plants (full production) and are due to a lack of information about the proper nutritional status of mango seedlings and the evaluated cultivars.…”

“…According to the classification by Quaggio (1996), the cultivar 'Agam' had Zn levels within the range considered suitable (between 30 and 50 mg•kg -1 ), while the cultivars 'Omer' and 'Shelly' had contents above the range considered adequate (> 50 mg•kg -1 ). Concerning cultivar development, according to Cohen et al (2016), because the cultivars 'Tommy Atkins' and 'Kent' are of the same genetic origin, the Zn contents found for the cultivar 'Shelly' are within the optimal range, which is between 51.7 to 168.1 mg•kg -1 for 'Tommy Atkins' and 43.7 to 108.9 mg•kg -1 for 'Kent' (Rezende et al, 2022). The cultivar 'Agam', which results from open pollination of the cultivar 'Shelly', also had values within the optimal range proposed by Rezende et al (2022).…”

“…Regardless of the nutrient studied, one should consider that the optimal ranges according to Quaggio (1996) and Rezende et al (2022) are defined for plants in production and at a different phenological point (flowering). On the other hand, comparing is justified by the absence of specific ranges for seedling formation.…”

Suitable mango rootstock selection has directly influenced plant mineral composition and vigor in the field. However, little is known about this in relation to mango cultivars in the São Francisco Valley region of Brazil. Thus, this study aimed to evaluate the dry matter accumulation and nutritional status of three Israeli mango seedling types ('Shelly', 'Omer', and 'Agam') grafted onto 'Coquinho' and 'Espada' rootstocks. The experiment was carried out between December of 2020 and April of 2021 in a nursery on the Agricultural Sciences Campus of the Federal University of São Francisco. It utilized a 3 × 2 factorial scheme, corresponding to the three Israeli mango cultivars as a scion and two rootstocks. Treatments were distributed in randomized blocks, with three replications and ten plants per plot. At 135 days after grafting, the dry matter and leaf nutritional status of the macronutrients, micronutrients, and sodium were evaluated. Seedlings with the Espada/Agam and Espada/Omer combinations showed greater vigor for transplanting in the field. The nutritional status of Israeli cultivars is not influenced only by the rootstock but also by the rootstock/rootstock combination, with higher nutritional concentrations for 'Espada' with 'Agam' and 'Omer', as well as 'Coquinho' with 'Shelly'. Properly choosing the rootstock and scion for Israeli mango seedling formation can improve management in the field, mainly in terms of plant nutritional needs.
