“…Potassium was the nutrient required in greatest quantities by the pineapple plant, which was in agreement with Teixeira et al (2011). Maximum accumulation of K in the plant was 1,404.25 kg ha -1 and occurred at 775 DAP, and the greatest demand for K, expressed by the greater rates of maximum accumulation in the plant and its components of leaves, stem, and roots, occurred from 550 to 775 DAP (Table 1), indicating, as for N, that the greatest demand for K by the pineapple plant occurs in the period before induced flowering, with greater rates of K being recommended in that period.…”

“…At the end of the 'Vitória' pineapple plant crop cycle to obtain mean yield of 72 t ha -1 of fruit, the following decreasing order of total accumulation of macronutrients was observed: 898 kg ha -1 of K, 452 kg ha -1 of N, 134 kg ha -1 of S, 129 kg ha -1 of Ca, 126 kg ha -1 of Mg, and 107 kg ha -1 of P, indicating greater N and K demand by the crop in comparison to other macronutrients, as indicated by Teixeira et al (2011). The 'Vitória' pineapple plant expressed intermediate capacity for taking up macronutrients in comparison to other studies undertaken with the cultivars Pérola and Smooth Cayenne, which showed mean accumulation ranging from 509-1,234 kg ha -1 of K, 238-450 kg ha -1 of N, 161-253 kg ha -1 of Ca, 33-157 kg ha -1 of Mg, 13-75 kg ha -1 of P, and 17-40 kg ha -1 of S (Hiroce et al, 1977;Py et al, 1987).…”

“…The nutritional demand of the pineapple plant is high in comparison to other crops and depends on the cultivar, weight of the fruit, and planting density, among other factors (Malézieux & Bartholomew, 2003;Silva et al, 2009;Teixeira et al, 2011). Studies with traditional cultivars, such as Pérola and Smooth Cayenne, have shown that the pineapple plant takes up an average of 509 to 1,234 kg ha -1 of K, 238 to 450 kg ha -1 of N, 161 to 253 kg ha -1 of Ca, 33 to 157 kg ha -1 of Mg, 13 to 75 kg ha -1 of P, and 17 to 40 kg ha -1 of S (Hiroce et al, 1977;Py et al, 1987).…”

SUMMARYThe nutritional state of the pineapple plant has a large effect on plant growth, on fruit production, and fruit quality. The aim of this study was to assess the uptake, accumulation, and export of nutrients by the irrigated 'Vitória' pineapple plant during and at the end of its development. A randomized block statistical design with four replications was used. The treatments were defined by different times of plant collection: at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP). The collected plants were separated into the following components: leaves, stem, roots, fruit, and slips for determination of fresh and dry matter weight at 65 ºC. After drying, the plant components were ground for characterization of the composition and content of nutrients taken up and exported by the pineapple plant. The results were subjected to analysis of variance, and non-linear regression models were fitted for the significant differences identified by the F test (p<0.01). The leaves and the stem were the plant components that showed the greatest accumulation of nutrients. For production of 72 t ha -1 of fruit, the macronutrient accumulation in the 'Vitória' pineapple exhibited the following decreasing order: K > N > S > Ca > Mg > P, which corresponded to 898, 452, 134, 129, 126, and 107 kg ha -1 , respectively, of total accumulation. The export of macronutrients by the pineapple fruit was in the following decreasing order: K > N > S > Ca > P > Mg, which was equivalent to 18, 17, 11, 8, 8, and 5 %, respectively, of the total accumulated by the pineapple. The 'Vitória' pineapple plant exported 78 kg ha -1 of N, 8 kg ha -1 of P, 164 kg ha -1 of K, 14 kg ha -1 of S, 10 kg ha -1 of Ca, and 6 kg ha -1 of Mg by the fruit. The nutrient content exported by the fruits represent important components of nutrient extraction from the soil, which need to be restored, while the nutrients contained in the leaves, stems and roots can be incorporated in the soil within a program of recycling of crop residues.Index terms: Ananas comosus var. comosus, dry matter, uptake rate. RESUMO: ABSORÇÃO, ACÚMULO E EXPORTAÇÃO DE MACRONUTRIENTES PELO ABACAXIZEIRO 'VITÓRIA' IRRIGADOO estado nutricional do abacaxizeiro tem grande influência no crescimento de suas plantas e na produção e qualidade de seus frutos. Este estudo teve o objetivo de avaliar a absorção, o acúmulo e a exportação de nutrientes pelo abacaxizeiro 'Vitória', irrigado nas fases de crescimento e produção. O delineamento estatístico utilizado foi em blocos casualizados, com quatro repetições. Os tratamentos foram definidos por distintas épocas de coleta de plantas: 270, 330, 390, 450, 510, 570, 690, 750 e 810 dias após o plantio (DAP). As plantas coletadas foram separadas nos seguintes componentes: folhas, talo, raízes, fruto e mudas, para determinar o peso de matérias fresca e seca a 65 ºC. Após secagem, os componentes das plantas foram moídos para caracterizar o teor e conteúdo de nutrientes absorvidos e exportados pelo abacaxizeiro. Os resultados foram submeti...

“…There have been many studies on the applications of various organic fertilizer onto pineapple plants, such as using composted poultry manure [17], composted pineapple residue return [18], and other composted materials [19][20][21][22]. According to Darnaudery, et al [23], 'Queen Victoria' pineapple fruits produced via organic fertilization produced the highest total soluble solids content (TSS) and lowest titratable acidity (TA) compared to inorganic fertilization.…”

Effect of Vermicompost Amendment on Nutritional Status of Sandy Loam Soil, Growth Performance, and Yield of Pineapple (Ananas comosus var. MD2) under Field Conditions

Vermicompost is the product of composting or breaking down organic matter through the use of earthworms. It is rich in essential plant nutrients, and has the ability to enhance the condition and increase the quality of the soil. In the present study, a field trial was conducted from January 2015 until March 2016 to elucidate the effects of vermicompost application (compared to supplementation with chemical fertilizer and no fertilizer) on the sandy loam soil and plant nutrients of pineapple (Ananas comosus var. MD2). The morphophysiology and yield performance of MD2 pineapple grown with vermicompost in the field were also evaluated. In this study, vermicompost was applied onto the sandy loam soils during transplanting, followed by a second application at seven MAP (months after planting) at the rate of 10 t ha−1. On the other hand, the chemical fertilizer was applied based on the normal conventional cultivation practice. The soil and D-leaf samples at six MAP (S1) and during the red bud stage (S2; 10 MAP) were used to determine the soil and plant nutrient contents. The morphology of the plants was evaluated every month, and the fruits that were produced were subjected to quality analysis. Data analysis revealed that soil pH was increased after a second supplementation of vermicompost and contained significantly higher total N (0.15%) in the soils compared to the control (0.07%). There was no significant difference between plants supplied with chemical fertilizer and vermicompost in terms of plant height, number of leaves, or the length and width of D-leaves. However, different fertilization treatments were found to affect the yield and physical characteristics of the resulting fruits. Plants supplied with chemical fertilizer produced the highest fruit yield (136.97 t ha−1) with the largest fruit size, followed by vermicompost (121.39 t ha−1) and the control (94.93 t ha−1). However, fruits supplied with vermicompost were observed to have the smallest crowns. Taken together, these results indicated that the use of vermicompost produced pineapple plants with excellent growth performance, comparable to that obtained when chemical fertilizer was used. Also, based on the cost analysis conducted, it was shown that the total cost (fertilizer and labor) for plants grown with vermicompost was lower than plants grown with chemical fertilizer. However, the usage of vermicompost as the single source of nutrients is not suggested for this type of soil and field conditions, but can be used as a supplement to maintain the soil quality and ensure agricultural sustainability.

“…Características nutricionais da planta, estimadas por meio de teores foliares de nutrientes na folha D interferem diretamente na produção de frutos, pois a produtividade do abacaxizeiro está vinculada ao estado nutricional da planta (COELHO et al 2007;FEITOSA et al, 2011;SPIRONELLO et al, 2004;TEIXEIRA et al, 2011). Segundo Silva e Lima Jr. (2010) para obtenção de 1,8 kg de massa média de fruto, é preciso que o conteúdo de N, presente na folha "D", no momento da indução floral esteja em 100 mg folha -1 , aproximadamente.…”
