“…Maximum stem diameter was 7.0 cm at 411 DAP and maximum daily growth rate was 0.21 mm day -1 (Table 2). A similar stem diameter (7.2 cm) at the flower induction stage was observed by Sampaio et al (2011) for the Gold cultivar.…”

“…This productivity is similar to the values recorded for cvs. Gold and Jupi (SAMPAIO et al, 2011), whereas Guarçoni and Ventura (2011) reported a maximum estimated production of 68.6 t ha -1 and an average fruit with crown weight of 1.34 kg for the MD-2 cultivar grown with 620.15 and 570.13 kg ha At the end of the pineapple cycle, the average total biomass accumulation was estimated at 326 and 68 t ha -1 of fresh and dry matter, respectively (Table 3). Of the plant parts evaluated, vegetative biomass accounted for an average total fresh and dry matter accumulation of 67.5% (222 t ha -1 ) and 80% (55 t ha -1 ), respectively (Table 3); whereas leaves alone accumulated 54 and 47% of total fresh and dry biomass.…”

“…These results are in accordance with the findings by Marques et al (2011), who reported that the vegetative growth of pineapple plants is drastically reduced after flowering/fructification when the plant's metabolism is directed to fruit development. These observations are common knowledge and serve as a basis for determining the phenological stages of pineapple plants (FOURNIER et al, 2010;RODRIGUES et al, 2010;SAMPAIO et al, 2011).…”

-This study aimed to evaluate the growth characteristics of irrigated Vitória pineapple plants grown in semi-arid conditions and determine its developmental stages based on those characteristics. It was used a randomized block design with four replicates. The experimental treatments were: plant harvest at 270, 330, 390, 450, 510, 570, 690, 750, and 810 days after planting (DAP). The following variables were determined: plant height, stem diameter, D-leaf length, D-leaf fresh and dry mass, biomass production of plants and plant parts (organs), and vegetative biomass. Five phenological stages are proposed based on vegetative biomass production: ≤ 20% biomass production (V1); 21-40% (V2); 41-60% (V3); 61-80% (V4); and > 80% (V5). The maximum growth rate for plant height, D-leaf length, and stem diameter was observed at the end of the phenological stage V1 (390-411 DAP), and at the end of stage V5 these plant traits had average values of 106, 82, and 7 cm, respectively. The maximum biomass accumulation rates were observed at stages V4 and V5, resulting in a final fruit yield and total fresh biomass of 72 t ha -1 and 326 t ha -1 , respectively. Finally, we estimated that 80% of the accumulated biomass may remain in the field after fruit and slip harvest, and could be incorporated as plant residue into the soil. Index Terms: Ananas comosus var. comosus, biomass production, maximum accumulation rate. CRESCIMENTO E PRODUÇÃO DO ABACAXIZEIRO 'VITÓRIA' IRRIGADO EM CONDIÇÕES DO SEMIÁRIDORESUMO -O estudo avaliou o crescimento do abacaxizeiro 'Vitória' irrigado em condições do semiárido brasileiro e definiu etapas de desenvolvimento por meio de características fenotípicas e morfológicas. O delineamento estatístico utilizado foi em blocos casualizados, com quatro repetições. Os tratamentos foram definidos por nove épocas de amostragem de plantas e seus componentes (270; 330; 390; 450; 510; 570; 690; 750 e 810 dias após o plantio -DAP). Foi avaliada a altura da planta, diâmetro do talo, comprimento e peso fresco e seco de folha 'D', a produção de biomassa total e dos componentes: folha, talo, raiz, fruto, coroa, filhotes e biomassa vegetativa, (folhas, talo e raiz). Por meio da produção relativa de biomassa vegetativa foram propostos cinco estádios fenológicos de crescimento do abacaxizeiro: até 20% de produção de biomassa-V1; 21-40%-V2; 41-60%-V3; 61-80%-V4; acima de 80%-V5. As características altura da planta, comprimento da folha 'D' e diâmetro do talo atingiram taxas de máximo crescimento no final do estágio fenológico V1 (390 e 411 DAP), e a estabilização destas características ocorreu no final do estágio V5, com valores médios de 106 cm, 82 cm e 7 cm, respectivamente. As taxas de máximo acúmulo foram observadas nos estádios V4 e V5, implicando a produção final de 72 t ha -1 de frutos e 326 t ha -1 de biomassa da planta (matéria fresca); desta última, estimou-se que 80% da biomassa acumulada pode permanecer na área de cultivo, após a colheita de frutos e mudas, como fonte de resíduos vegetais para o solo.

“…Resultados similares para diferentes variedades foram observados por diversos autores (SPiRonello et al, 2004;GuARÇoni M.;ventuRA, 2011;SilvA et al, 2012); porém, diferentemente do observado por veloso et al (2001). A massa média obtida para o fruto do 'BRS imperial' com coroa foi acima dos 670 g observados por Sampaio et al (2011) e abaixo dos 1.535 g e 1.792 g observados por Ramos (2006) e Cabral e Matos (2009), respectivamente, diferenças essas que podem ser devidas às irrigações ministradas, o tipo de amostragem de frutos para representar sua massa ou do tipo de muda utilizada.…”

RESUMO-o abacaxizeiro 'BRS imperial' é uma cultivar resistente à fusariose, apresenta frutos saborosos, mas ainda é pouco conhecido dos fruticultores. este trabalho teve como objetivo avaliar o efeito de diferentes doses de n e K nas características químicas do solo, nos teores foliares de nutrientes e nas variáveis de produção de um cultivo de 'BRS imperial'. o experimento foi instalado no espaçamento 0,90 x 0,40 x 0,40 m, com quatro doses de n (0; 160; 320 e 550 kg ha NK FERTILIZATION IN 'BRS IMPERIAL' PINEAPPLE -II -VARIABLE OF PLANT PRODUCTIONABSTRACT -the 'BRS imperial' pineapple is a resistant cultivar to Fusarium and it presents tasty fruit, but it is still little known by farmers. This study aimed to evaluate the influence of N and K fertilization on chemical soil characteristics, leaves nutrient contents and yield of 'BRS imperial' plants. the experiment was installed at a 0.90 x 0.40 x 0.40 m spacing and four doses of n (0, 160, 320, 550 kg ha -1 ) and K 2 o (0, 240, 480 and 600 kg ha -1 ) were tested in a completely randomized blocks design with five replicates, in a 4 x 4 complete factorial scheme. Chemical analyzes were made of leaves and soil and measured the production variables. the cultivation of pineapple in a complete absence of n and K fertilization resulted in lower ph, K + , Ca 2+ and Mg 2+ levels of soil in relation to the initial content. even at the highest dose of K 2 o, the K level in the soil was low after the pineapple cultivation. the maximum n and K foliar content, estimated on the higher doses, were 13 g kg -1 and 32 g kg -1 , respectively. Crop variables showed significance for N levels in all evaluations, while the rates of K 2 O influenced only the length/diameter fruit relation. In a quadratic regression, n doses showed 1,086 g on fruit weight with crown at 365 kg ha -1 of n and a yield of 42 t ha -1 .

The cv. Imperial has great commercial potential. Its expansion depends, to a large extent, on the adjustment to the fertilization recommendations proposed in the fertilization and liming recommendation bulletins of the main producing states, in order to have adequate nutritional management. The objective of this study was to verify the growth of leaf D and the productivity of 'Imperial' pineapple cultivated under the presence and levels of fertilization of N and K. The experimental design was a randomized complete block with three replicates and treatments were arranged in a factorial scheme according to the Plan Plueba III matrix, with five doses of N (15; 90; 150; 210 and 285 kg ha -1 ) and five doses of K (21.6, 129.6, 216.0, 302.4 and 410.4 kg ha -1 ). Data were submitted to analysis of variance. To evaluate the effect of the interaction of N and K doses and days after planting, the response surface technique was used.
