“…The values for N present in the leaves with both aerobic and anaerobic biofertilisers are below the range considered suitable for leaves of the banana plant (MOREIRA; FAGERIA, 2009), where a value of 24.02 g kg -1 is considered satisfactory. Similarly, Moreira and Fageria (2009), analysing the effect of organic fertilisation using biofertiliser with aerobic fermentation in leaves of the banana "Pacovan", recorded values lower than those of this study (18.09 g leaf N kg -1 ). However, Viana et al (2013), analysing the effect of organic fertilisation using bovine and mixed biofertiliser with aerobic fermentation on the leaves of melon plants, recorded values greater than those in this study (35.00 g leaf N kg -1 ).…”

“…The mean values obtained with the biofertilisers exceeded those considered satisfactory by Moreira and Fageria (2009), i.e., 1.59 g kg -1 in the banana "Thap Maeo". In contrast to the present study, Santos et al (2014b), working under field conditions, found a leaf P content of 1.4 g kg -1 in the banana "Pacovan".…”

-Banana farming is an activity of great economic and social importance, and is carried out in most tropical countries. The aim of this work was to evaluate the biomass accumulation and levels of nitrogen (N), phosphorus (P), potassium (K), calcium (Ca) and magnesium (Mg) in micropropagated plants of the banana "Prata Catarina" during the acclimatization phase, under different types and doses of biofertilisers. The experimental design included randomised blocks in a 2 × 5 + (2) factorial scheme, with two types of liquid biofertilisers (bovine biofertiliser with anaerobic and aerobic fermentation) and five biofertiliser doses (0.25, 0.50, 0.75, 1.00, and 1.25 L plant -1 week -1 ), as well as two additional treatments (control and recommended mineral fertilisation). The following variables were analysed: dry weight of the leaves and roots, and mineral element content (N, P, K, Ca, and Mg) in different parts of the plant (leaf and root). During 90 days of acclimatization, the nutritional contribution of bovine biofertiliser with anaerobic fermentation was greater in comparison with the biofertiliser with aerobic fermentation and the control, but lower in comparison with mineral fertilisation. The 1000-mL dose of the biofertiliser with anaerobic fermentation promoted greater dry weight accumulation in the leaves and roots of the banana "Prata Catarina". The biofertiliser with anaerobic fermentation promoted higher levels of N, K, and Ca in the leaves, whereas the biofertiliser with aerobic fermentation promoted higher levels of P in the leaves and roots.Keywords: Musa sp..

ACÚMULO DE BIOMASSA E NUTRIÇÃO DE MUDAS MICROPROPAGADAS DE BANANEIRA PRATA CATARINA ADUBADAS COM BIOFERTILIZANTESRESUMO -A bananicultura destaca-se como uma atividade de grande importância econômica e social, sendo explorada na maioria dos países tropicais. O presente trabalho propôs avaliar o acúmulo de biomassa e os teores de nitrogênio (N), fósforo (P), potássio (K), cálcio (Ca) e magnésio (Mg) em mudas micropropagadas de bananeira cv. Prata Catarina, durante a fase de aclimatização sob diferentes tipos doses e de biofertilizantes. O delineamento experimental foi em blocos casualizados em arranjo fatorial 2 × 5 + (2), referentes a dois tipos de biofertilizantes líquidos (bovino de fermentação anaeróbia e aeróbia) e cinco doses de biofertilizantes (0,25; 0,50; 0,75; 1,00 e 1,25 L planta -1 semana -1 ), com dois tratamentos adicionais (controle e adubação mineral recomendada). Foram analisadas as seguintes variáveis: massa seca das folhas, das raízes e teores de elementos minerais (N, P, K, Ca e Mg) nas diferentes partes da planta (folha e raiz). O biofertilizante bovino com fermentação anaeróbia apresenta maior aporte nutricional em relação biofertilizante de fermentação aeróbio e ao controle, porém menor em relação à adubação mineral para as mudas durante os 90 dias de aclimatização. A dose de 1000 mL do biofertilizante com fermentação anaeróbia promove maior acúmulo de massa seca nas folhas e raízes da ...

Acúmulo de matéria seca e distribuição de nutrientes em duas cultivares de bananeiras irrigadas com água moderadamente salina RESUMO O acúmulo de matéria seca e a distribuição de nutrientes nas plantas são influenciados pelas interações competitivas existentes no ambiente e na cultura. O objetivo deste estudo foi avaliar o efeito do uso de água moderadamente salina no acúmulo de matéria seca e a distribuição de nutrientes em duas cultivares de bananeiras, Grand Naine e Prata Anão, na fase produtiva. O experimento foi conduzido entre junho/2004 e maio/2005 em um Neossolo litólico, em Quixeré, CE, onde essas cultivares foram plantadas e irrigadas com água de condutividade elétrica de 1,66 dS m -1 . A partir dos 210 dias após o plantio, em intervalos de 45 dias, as plantas de quatro touceiras, escolhidas aleatoriamente, foram amostradas e separadas, em suas diversas partes, para análise. Observou-se 63% do acúmulo de N, P, K, Ca, Mg, Cl e Na nas folhas e pseudocaule da bananeira, e 37% no cacho, evidenciando a importância da restituição de nutrientes para a manutenção do bananal; além disso, com o passar do tempo, o acúmulo de matéria seca, K, Ca e Cl das partes aéreas das plantas reduziu, e o do cacho aumentou nas duas cultivares.

This study was carried out with the objective to evaluate the influence of irrigation with slightly saline water on dry matter accumulation and nutrients distribution in two banana cultivars, Grand Naine and Prata Anã, on the production stage. The experiment was conducted between June 2004 and May 2005 in an Udorthent in Quixeré, Ceará, Brazil, where the cultivars were planted and irrigated with water with 1.66 dS m -1 electrical conductivity. From the 210 th day after the planting, in 45 days intervals, the plants of four randomly chosen clumps were sampled and separated into different parts for analysis. It was observed that 63% of the total N, P, K, Ca, Mg, Na and Cl were accumulated on the shoot components of the banana tree, and 37% on the bunch, showing the importance of nutrients replacements for the management of the banana crop, and that, as time went by, the accumulation of dry matter, K, Ca and Cl reduced on the shoot and increased on the bunch in both the cultivars.
