Adubação fosfatada em mudas de bananeira 'Prata anã'(AAB), cultivadas em dois Latossolos

Abstract: Phosphorus fertilization in banana 'Prata anã' (AAB) cultivated in two latosolsData on the effect of phosphorus on the development of banana are scarce. The objectives of this work were to evaluate the effect of the application of phosphorus on the development of banana "Prata Anã" growing in a Red Latosol (RL) and a Red-Yellow Latosol (RYL), as well as to determine the phosphorus critical level. The treatments were arranged in a randomized design, using a 8 x 2 in factorial arrangement, with three replication… Show more

“…Em casa de vegetação, Silva et al (2011) também encontraram resposta positiva à aplicação de P por mudas de bananeira 'Prata Anã', com aumento no diâmetro do pseudocaule e na altura das plantas em solos com baixo teor de P disponível (3,3 e 2,4 mg dm -3 , respectivamente).…”

“…O teor médio de P na folha, nos quatro ciclos, foi de 1,6 g kg -1 , que se encontra dentro da faixa de suficiência estabelecida por Silva et al (2002) para a bananeira 'Prata Anã' (1,5-1,9 g kg -1 ). Silva et al (2011), entretanto, verificaram que o teor de P nas folhas de mudas de bananeira 'Prata Anã' aumenta linearmente com a aplicação de doses crescentes de P. Esses autores determinaram o teor de P com a análise conjunta de todas as folhas das mudas, diferentemente da análise feita no presente trabalho, em que o teor de P foi determinado apenas na terceira folha a partir do ápice. Essa folha possivelmente não é adequada para a análise, uma vez que o P disponível no solo elevou-se linearmente com as doses do nutriente (Figura 2) e os teores foliares não.…”

“…The results corroborate the findings of Reis and Chepote (2008), who evaluated the effect of P on 'Pacova' banana (AAB) in dystrophic red-yellow latosol (oxisoil), they also reported a quadratic function on plant height and pseudo-stem circumference. However, banana does not require large amounts of P (Silva and Rodrigues, 2013), phosphorus fertilization has proved to be necessary for growing 'Maçã' banana, which increases pseudo-stem diameter (4.6%), but available P content tends to be extremely low in most latosols, because assimilable forms is restricted to a few plant (Silva et al, 2011). P can notably increase vegetative growth; being indispensable for cell division, as it is a constituent element of nucleoproteins (Malavolta, 1997).…”

“…Moreover, Silva et al (2011) found that depending on the type of the soil, where banana grows, P can be used more efficiently by plants, resulting in higher dry matter production, i.e. inferring a need of providing P, when working with banana.…”
