Resumo: The objective of this research is to characterize the development and yield of banana trees in the Southwest region of Goiás and to adjust different combination levels of N and K. The experiment was conducted in dystrophic red Oxisol, in the district of Rio Verde, Goiás, and consisted on five doses of increasing rates of N and K (N0/K0 - 0 kg ha-1 year-1 of N and 0 kg ha-1 year-1 of K; N1/K1 - 150 kg ha-1 year-1 of N and 200 kg ha-1 year-1 of K ; N2/K2 – 300 kg ha-1 year-1 of N and 450 kg ha-1 year-1 of K; N3/ K3 – 450 kg ha-1 year-1 of N and 600 kg ha-1 year-1 of K; N4/K4 - 600 kg ha-1 year-1 of N and 800 kg ha-1 year-1 of K), applied to two cultivars of bananas, Thap Maeo and Prata-anã. The evaluations conducted in the plants were: plant height, pseudo stem diameter and leaf number at 150 days after planting (DAT) and at flowering. The plants were assessed at the flowering and at the harvest observing the following yield components: the time elapsed between planting and flowering, leaf number at harvest, number of bunch per cluster and number of fruits in the second bunch, the length of the stem and the fruits in the second bunch, the diameter of the stem and fruits in the second bunch and the weight of the bunch, the stem and the fruits in the second bunch. The banana plants were sampled at flowering for analyzing the nutrient content. With the data of yield components were calculated durability index of the leaf and absolute rate of banana growth. The results were submitted to ANOVA and regression, and the mean comparison by the Tukey test. The attributes of development, production and leaf levels of nutrients in Thap Maeo and Prata-Anã were influenced by different rates of combined N and K. The smallest interval between flowering days was found with rates of 300 kg ha-1 of N and 450 kg ha-1 of K in Thap Maeo. There was no better combination of N and K parameters for the development, production and leaf levels of nutrients in Prata-Anã.

O experimento foi conduzido em Latossolo Vermelho distrófico, no município de Rio Verde, Goiás. Os tratamentos consistiram em cinco doses crescentes e combinadas de N e K (N0/K0 - 0 kg ha-1 ano-1 de N e 0 kg ha-1 ano-1 de K; N1/ K1 - 150 kg ha-1 ano-1 de N e 200 kg ha-1 ano-1 de K ; N2/K2 – 300 kg ha-1 ano-1 de N e 450 kg ha-1 ano-1 de K; N3/K3 – 450 kg ha-1 ano-1 de N e 600 kg ha-1 ano-1 de K; N4/K4 - 600 kg ha-1 ano-1 de N e 800 kg ha-1 ano-1 de K), aplicadas em duas cultivares de banana, Thap Maeo e a Prata-Anã. As avaliações realizadas nas bananeiras foram: altura das plantas, diâmetro do pseudocaule e número de folhas aos 150 dias após plantio (DAT) e na época do florescimento. As plantas foram avaliadas no florescimento e na colheita das bananeiras, observando os seguintes componentes de produção: intervalo em dias entre o plantio e o florescimento, número de folhas na colheita, número de pencas por cacho e frutos na segunda penca, comprimento do engaço e dos frutos na segunda penca, diâmetro do engaço e dos frutos na segunda penca e peso do cacho, engaço e dos frutos na segunda penca. Amostras foliares das bananeira foram realizadas no seu florescimento e foram analisadas para obter os teores de macro e micronutrientes. Com os dados dos componentes de produção, calcularam-se o índice de durabilidade das folhas e a taxa de crescimento absoluto do pseudocaule das bananeiras. Os resultados foram submetidos a ANOVA e regressão, e a comparação de médias foi feita pelo teste de Tukey. Os atributos de desenvolvimento, a produção e os teores de macronutrientes e micronutrientes nas folhas da Thap Maeo e Prata-Anã foram influenciados pelas diferentes doses combinadas de N e K. O menor intervalo de dias entre o florescimento foi encontrado com as doses de 300 kg ha-1 de N e 450 kg ha-1 de K na Thap Maeo. Não houve melhor combinação das doses de N e K para os parâmetros de desenvolvimento, produção e teores foliares na Prata-AnãSociedade Brasileira de Fruticultura2015-12-15T12:27:21Z2015-12-15T12:27:21Z2012-03-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfRATKE, R.
