Liming in Growing Mango Cultivar Keitt in Production

Abstract

The tropical soil acidity is one of the main limiting factors for crop productivity. This study aimed to evaluate the effects of application of limestone dose to soil fertility, nutritional status of the crop, and productivity and quality of the fruits of mango, cultivar Keitt. The study was carried out at Selvíria, state of Mato Grosso Sul, Brazil, in a Typic Haplustox (pH in CaCl 2 = 4.7), cultivated with mango cultivar Keitt grafted on Coquinho pattern in the production phase (13 years old). Treatments were composed of limestone doses (0, 1.55, 3.10, 4.65, and 6.20 t ha −1 ), arranged in blocks at random with three repetitions. The limestone was applied and incorporated in the surface layer of 0 to 5 cm deep in the total area. We evaluated the chemical attributes of the soil [pH, hydrogen (H+) aluminum (Al), calcium (Ca), magnesium (Mg), potassium (K), and sum of bases and base saturation] at 16 and 28 months after liming (layer 0 to 20 cm deep), the nutrition of plants at 12 months after liming, and quality of the fruit in two crop years. Liming promoted improvements in soil chemical attributes, reflected in the nutritional status, productivity, and quality of mango fruit. Also, there was a linear effect with the application of lime dose on the productivity of the fruit, but after the second year of evaluation.

Using Limestone to Improve Soil Fertility and Growth of Mango (Mangifera Indica L.)

“…It is observed that the point of maximum accumulated fruit yield of the mango tree, 18,846 kg ha −1 crops (2008/09 and 2009/10) occurred when the soil base saturation index was 51% ( Figure 5). This value is below that suggested by (Quaggio, Van Raij, and Piza Júnior 1997) for the mango crop in the state of São Paulo (V% = 80%) and below that found by (Almeida et al 2008) (V% = 71%) in orchards in production. It should be noted that in the recommendation of (Quaggio, Van Raij, and Piza Júnior 1997), it is not indicated whether the V% refers to mango orchards under implementation or if this recommended value of V% refers to orchards in formation or production.…”

Soil salinity and yield of mango fertigated with potassium sources

“…K has an essential role in enzymatic activation, photosynthesis, water use efficiency, formation of starch and protein synthesis (Stino et al, 2011;El-Razek et al, 2013). On the other hand, the excess of K can cause imbalance in the levels of calcium and magnesium (Almeida et al, 2015), which evidences the importance of a good fertilization program. The present study aimed to evaluate soil salinity, number of commercial fruits and yield of mango, cv.…”

Precision agriculture tools for liming management in mango orchards in the Brazilian semiarid region

“…It is important to correct the Ca 2+ level, which is above the optimum values since its highest content is found in mango leaves (Silva et al, 2014), and calcium deficiency can depreciate the quality of the fruit, as low concentration of leaf Ca is associated with the incidence of internal collapse in mango (Almeida et al, 2015). Therefore, higher calcium content in the fruit slows ripening and senescence, by reducing respiration, ethylene evolution and loss of fresh weight, extending post-harvest life and fruit quality of mango (Aular & Natale, 2013;Hojo et al, 2009).…”
