“…3D, which the behavior of fruit length with and without crown were linear and the diameter of the fruit had a quadratic association with the increasing rates of potassium, with the highest value for 550 kg ha -1 of K 2 O (11.89 cm), and linear behavior nitrogen to these variables, showing that this nutrient was decisive in the vegetative development of the plant, which in turn led to greater fruits with lower crown. These results differ from Rios et al (2018), working with ‹Imperial› pineapple observed a linear increase for the diameter of the fruit in relation to the rates of potassium applied on soil.…”

“…Reduction of crown length on pineapple fruits with increasing N and K 2 O rates, was also reported by Rios et al (2018). The authors concluded that the reduction of the crown is a desired factor when there is an increase in the infructescence and for fruits destined to exportation, once the ideal crown length is between 5.00 and 13.00 cm, due to the standardization of packages.…”

Production and quality of 'Pérola' pineapple under fertigation

et al. 2020

The aim of this paper is to evaluate the yield and quality of 'Pérola' pineapple under increasing rates of nitrogen and potassium applied through fertigation. The experiment was conducted in a randomized block design, with four replications, in a factorial scheme (4x4), which represents four nitrogen rates (128, 256, 384 and 512 kg ha-1 of N) and four potassium rates (192, 384, 576 and 768 kg ha-1of K2O) via fertigation. The evaluations consisted of physical and chemical fruit characteristics and yield. Increasing nitrogen rates provided linear growth on fruit production features and the rate of 516 kg ha-1 resulted in fruits with the largest diameters. The highest total yield on 'Pérola' pineapple crop was reached on plants under the supply of 498 kg ha-1 of K2O. Rates between 523 and 583 kg ha-1 of K2O, provided the largest fruit matter and the highest fruit pulp yield. The increasing amount of nitrogen applied by fertigation resulted in linear growth on fruit pulp pH, though it did not influence the soluble solids content. The lower acid content and higher SS/acid ratio on fruits were reached with the N rates of 333 and 375 kg ha-1 respectively.

“…The authors verified that this cultivar is highly responsive to fertilization, with increasing linear responses to nitrogen application, and that the dose of 498 kg ha -1 of K 2 O provides the highest yield of pineapple fruits, 66.9 t ha -1 . Rios et al (2018) working with the cultivar 'Imperial' and increasing doses of potassium verified similar results for the conditions of the state of Paraíba, noting quadratic effect for potassium doses and that 410.4 kg ha -1 of K 2 O. The fruit and crown mass increases, length and diameter of infructescence and soluble solids content.…”

Cultural treatments in pineapple crop. Management for high yield – Review

et al. 2021

View full text Add to dashboard Cite

Several factors influence in the vegetative development, yield and quality of pineapple fruits, among which the cultural treatments adopted throughout the production cycle stand out, mainly weed control, mineral nutrition, irrigation and induction artificial flowering. The purpose of this review was to present the main advances in research on cultural treatments in the cultivation of pineapple (Ananas comosus L. Merril) and their effects on yield and fruit quality. Current research shows that interventions for weed management, through chemical control with herbicides or the adoption of organic or inorganic soil cover are strategies that can be adopted by producers who seek to reduce labor costs and provide good conditions for plant development. The use of mulching is a promising and effective practice, given the cost reduction with polluting herbicide applications and improvement of the physicochemical quality of the soil. Regarding mineral nutrition, pineapple is a rustic plant, tolerant to soils with moderate acidity and low levels of nutrients in the soil, however, liming and fertilization are essential for crops where high yields are sought. In the same way, it is verified that the pineapple, even being a CAM metabolism plant, tolerant to situations of water stress, is highly responsive to irrigation, which provides improvements in the vegetative and reproductive development of the plant. Another essential management practice in pineapple crops is artificial floral induction, a practice that aims to synchronize the flowering period, facilitate harvesting and ensure a consumer market in times when the supply of fruit is scarce

“…Ascorbic acid content is used as quality index for pineapple fruits, varying according to management conditions (LEE and KADER, 2000;RIOS et al, 2018). Ascorbic acid content in fruits of the complete treatment was 80.8 mg L -1 (Table 3) below that reported by Ramos et al (2010) who observed levels above 100 mg L -1 of vitamin C. In the treatment with nitrogen deficiency, vitamin C content had an increase of 46.8% over the complete treatment solution.…”

“…Some studies on mineral nutrition and fruit quality with pineapple cultivars such as 'Vitória' (CAETANO et al, 2013) 'Gold (MD-2)' (GUARÇONI and VENTURA, 2011), 'Jupi' (COELHO et al, 2007), 'Pérola' (VELOSO et al, 2001) and 'Imperial' (RAMOS et al, 2010;OLIVEIRA et al, 2015;RIOS et al, 2018) demonstrate the influence of nitrogen and potassium on soluble solids and titratable acidity, juice yield and vitamin C content, with each cultivar presenting its peculiarities. In general, nitrogen has a negative effect on soluble solids and titratable acidity, while potassium has a positive effect on these characteristics.…”

Fruit quality of pineapple ‘Vitória’ under macronutrients and boron deficiency

et al. 2019

View full text Add to dashboard Cite

The objective of this study was to evaluate the influence of macronutrient and boron deficiencies on physico-chemical characteristics of pineapple fruits, ‘Vitoria’ cultivar. The experimental design was a randomized complete block with eight treatments (complete solution, -N, -P, -K, -Ca, -Mg, -S and -B) and six replicates. The experiment was conducted from October 2016 to March 2018, and the variables evaluated were: fresh fruit and crown mass, fruit diameter, fruit and crown length, juice volume and mass, titratable acidity (TA), soluble solids (SS), vitamin C, juice pH and SS/TA ratio. All treatments with nutrient deficiency reduced the fresh fruit mass. In treatments -N and -Ca there was a reduction of 41.9 and 35.3%, respectively, in the crown fresh mass. Fruits diameter under N, K and Mg deficiency was lower, fruit length, soluble solids and juice pH were lower in treatment with N deficiency. Isolated deficiencies of each of the macronutrients and B reduced the mass of the whole fruit and the crownless fruit. The nutrient that most limited the size and quality of ‘Vitoria’ pineapple fruit was nitrogen.
