Abstract
The objective of this research was to evaluate the nutritional status and yield of ‘Prata’ bananas fertilized with different sources for organic management applied to soils with improved fertility. Two cultivars (‘Prata-Anã’ and ‘BRS Platina’), five annual potassium rates (0, 200, 400, 600, and 800 kg ha-1 of K2O) supplied by bovine manure and rock powder, and six evaluation periods (210, 390, 570, 750, 930, and 1.110 days after transplanting – DAT) were laid out in a randomized block design, in a 2 x 5 x 6 factorial arrangement with three replicates. The yield was determined over three cycles. The levels of K and S in leaves increased with increasing rates of K2O interacting with the evaluation periods. The levels of N, P, and Cu increased with increasing rates of K2O. High soil fertility and manure and rock powder applications were not enough to maintain appropriate levels of leaf Mn in ‘Prata-Anã’. The levels of leaf K, S, Cu, and Zn in the cultivar Prata-Anã differed from those of the ‘BRS Platina’. Applying manure and rock powder as organic fertilizers did not increase the yield of ‘Prata-Anã’ and ‘BRS Platina’ banana plants grown on soils with improved fertility during four production cycles. Keywords: Musa spp.; leaf tissue analysis; yield. Estado nutricional e produção de bananeiras ‘Prata-anã’ (AAB) e ‘BRS Platina’ (AAAB) com fertilização orgânica RESUMO: Objetivou-se esta pesquisa avaliar o estado nutricional e o rendimento de bananeiras 'Prata' com diferentes fontes de fertilização para manejo orgânico em solos com fertilidade melhorada. Duas cultivares ('Prata-Anã' e 'BRS Platina'), cinco doses anuais de potássio (0, 200, 400, 600 e 800 kg ha-1 de K2O) fornecidas por meio de esterco bovino e pó de rocha, e seis períodos (210, 390, 570, 750, 930 e 1.110 dias após o transplantio), distribuídos em delineamento de blocos ao acaso, em esquema fatorial 2 x 5 x 6 com três repetições. O rendimento foi determinado por três ciclos. Os teores de K e S nas folhas aumentaram com aumento das taxas de K2O em interação com os períodos de avaliação. Os níveis de N, P e Cu aumentaram com o aumento das doses de K2O. A alta fertilidade do solo e as aplicações de esterco e pó de rocha não são suficientes para manter os níveis adequados de Mn em ‘Prata-Anã’. Os teores de K, S, Cu e Zn na cultivar Prata-Anã diferem de ‘BRS Platina’. O esterco e o pó de rocha como fertilizantes orgânicos não aumentam o rendimento das bananeiras ‘Prata’ cultivadas em solos com fertilidade melhorada durante quatro ciclos de produção. Palavras-chave: Musa spp.; análise de tecido foliar; rendimento.
