“…Baldotto et al (2009) state that the application of organic compounds promoted vegetative growth in cultured plants of pineapple "Vitória" during the acclimatization phase. Nomura et al (2012) found that at 98 days after transplanting, the micropropagated plants of the banana "Grand Naine" accumulated greater shoot dry biomass at a dose of 4.0 mL plant -1 of the commercial biofertilisers HUMITEC ® and RUTER AA ® (15.1 g). The superiority of the biofertiliser with anaerobic fermentation with respect to the one with aerobic fermentation is in the quantities of essential elements (Table 2), i.e., anaerobic fermentation likely improves the availability of these nutrients in the study substrate.…”

-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 ...

“…Taxas de sobrevivência de mudas de bananeira superiores a 90% têm sido relatadas por diversos autores (Pereira et al, 2005;Oliveira et al, 2008). Embora a fase de aclimatização seja considerada uma etapa delicada para várias culturas, as taxas de sobrevivência observadas em diferentes estudos demonstram que mudas micropropagadas de bananeira apresentam excelente capacidade de adaptação ao sistema ex vitro (Nomura et al, 2012).…”

“…In relation to the banana tree, Nomura et al (2012) and Russo et al (1995) reported positive results after applying these substances to seedlings grown under controlled conditions. Coelho et al (2016) studied the drip irrigation of humic substances (doses up to 42.42 L ha -1 cycle -1 ), in a Dystric Densic Xantic Ferralsol cultivated with 'BRS Princesa' banana trees, and found no effects on the plant performance or soil physical-hydraulic attributes, during the first production cycle of the orchard.…”

Fertigation with humic substances products has been adopted in commercial banana tree plantations. However, there are few studies on the procedure to confirm its technical feasibility. This study aimed at assessing the effects of fertigation with humic substances on the chemical attributes of a Dystric Densic Xantic Ferralsol cultivated with the 'BRS Princesa' banana tree cultivar and on the agronomic performance of the orchard. The experiment was conducted using a randomized blocks design, with six treatments and four replications. Treatments consisted of a monthly application of humic substances doses based on the commercially recommended reference dose for the banana plantation (12.09 kg ha-1 cycle-1). The doses used were equivalent to percentages of the reference dose (100 %, 150 %, 200 %, 250 % and 300 %), in addition to the control. No significant effects of the fertigation with humic substances that could justify the use of the product at the doses assessed were observed on the soil chemical attributes, banana growth and yield.
