“…Silva and Simão (2015) recorded similar bunch weight when carrying out trials with K fertilization; though, with lower overall yield due to the lower population (1,235 plants ha -1 ). Damatto Junior et al (2011), with organic fertilization, reported an increase in bunch weight from the 1st to the 2nd cycle, with lower values than those herein, followed by a reduction in the 3rd cycle, reduction of which was claimed to be due to nutrient depletion of the soil.…”

The aim of this paper is to evaluate gas exchanges and yield of Prata-type banana plants subjected to fertilizer sources for organic management in soil with improved fertility. Two cultivars ('Dwarf-Prata' and 'BRS Platina'), 5 K 2 O rates (0, 200, 400, 600, and 800 kg ha -1 year -1 ) supplied by cattle manure and Naturalplus ® rock powder, and 2 evaluation times (8:00 am and 2:00 pm) were arranged in a randomized complete block design with 15 replicates. As for production, a randomized block design with 4 cycles and 3 replicates was used. In fertile soils, gas exchanges are little influenced by fertilization. Fertilization with increasing application rates determines a quadratic variation in stomatal conductance and internal CO 2 concentration in 'Dwarf-Prata' and a linear variation for leaf temperature and instantaneous water-use efficiency in 'BRS Platina'. Quantum efficiency of photosynthesis is higher at 8:00 am, whereas at 2:00 pm, for leaf temperature. Photosynthesis and leaf transpiration directly correlate with stomatal conductance, instantaneous water-use efficiency, and leaf temperature, while instantaneous water-use efficiency and photosynthesis inversely associate with transpiration and leaf temperature. Cattle manure and rock powder fertilizations do not increase yield in banana plants grown in soils with improved fertility.

“…Donato et al (2015) argue that well-managed banana plantations growing on improved soil conditions have yields higher than 40 t ha -1 per year (high productivity>32 t ha -1 per year). Silva and Simão (2015) report a similar bunch weight, but a lower yield per unit area owing to a lower planting density, 1.235 plants ha -1 . Damatto Junior et al (2011b), working with organic fertilization, report an increase in bunch weight from the first to the second cycle, but bunch weight decreases in the third cycle due to soil nutrient depletion.…”

“…Despite the low concentration of K in animal-sourced organic fertilizers, the whole content of this macronutrient is mineralized, thus it was released into the soil as fast as mineral K fertilizer, while rock-based fertilizers slowly release K into the soil. Using mineral fertilizers, Silva et al (2011), , and Silva and Simão (2015) report linear increases in leaf K level in 'Prata-Anã' banana as a function of K2O rates over four cycles. However, Damatto Junior et al (2011a) report no effects of organic fertilizer rates as high as 630.4 kg ha -1 per year on the leaf nutrient content of 'Prata-Anã' banana over five production cycles.…”

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.
