“…It should be noted that phosphorus is an element that favours the development of root system in banana (FLORI;RESENDE, 2016). Results contrary to those of this study were reported by Santos et al (2014b), who analysing the mineral element content of banana "Pacovan" plants fertilised with biofertiliser.…”

-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 ...

“…This effect might be related to K having great mobility inside the plants (FLORI;RESENDE, 2016). Another contributing factor for the reduction of K in the roots might be the high levels of Na present in the biofertilisers (Table 2).…”

“…Similar results were obtained by Maluf et al (2015) and by Flori and Resende (2016). Maluf et al (2015) found in the coffee area, both at 0-0.1m and 0.1-0.2m soil layers, higher values of pH, organic matter, Ca 2+ , Mg 2+ and row saturation than in the transplant line, in the fertilizer strip.…”

Flori and Resende (2016) obtained, at 0-0.2m soil layer, higher levels of organic matter, P and Ca 2+ between rows in relation to the banana plantation row. According to these authors, these results were due to the lower nutrient absorption by the banana between rows, due to the smaller root volume at the site and the greater distance from the rhizome.…”

In soil sampling, the collection site and the tool used may induce errors that can compromise the results of the chemical analysis and, consequently, the definition of corrective and fertilizer doses. The objective in this study was to evaluate soil sampling sites and tools in a coffee growing area. The experiment was carried out in a field in the municipality of Alfenas-MG, in a 35-year coffee field. A randomized block design was used in a 3 x 5 factorial scheme and 4 replications, totaling 60 experimental units. The treatments consisted of 3 sampling sites: in the fertilizer strip (located in the projection of the plant canopy); between rows; and in the total area, with 1/3 of the samples collected under the canopy and close to the plant stem, 1/3 in the canopy projection and 1/3 collected between rows; and 5 sampling tools: Dutch auger; screw auger; probe; hoe and drill. Soil samples were collected at a depth of 0 to 0.2 m, and each composite sample was obtained by assembling and mixing 20 single samples. At each sampling point, an area of 2m2 was delimited, in which simple samples were collected in all the evaluated places and with all the tools used. The following parameters were determined in the soil samples: pH in CaCl2; potential acidity (H+Al); organic matter; P, extracted by Mehlich; K+, Ca2+, Mg2+ and base saturation. In a coffee-growing area, he fertilizer strip (canopy projection) has topsoil with higher acidity and lower contents of organic matter and nutrients P, K+, Ca2+ and Mg2+ than between rows. The tools used for soil sampling do not influence the results of soil chemical analysis in the coffee-growing area.

“…A banana é uma das frutas mais consumidas no mundo, sendo explorada na maioria dos países tropicais (Flori e Resende, 2016), pois é um alimento altamente energético com elevado conteúdo de carboidratos assimiláveis (Perin et al, 2009), além do mais, é uma espécie adaptada às condições de sub-bosque florestal, pelo fato de ser tolerante ao sombreamento (Santos et al, 2012).…”
