“…Four months after planting and during the flowering of each cycle, 25 g of Mg and 30 g of K 2 O per cluster of plants were applied broadcast, using magnesium sulfate and potassium chloride. Applications of B and Zn were performed in the rhizome (Rodrigues et al, 2007;Nomura et al, 2011) of the thinned seedling, every four months, with 1.7 g of B, as boric acid, and 4 g of Zn per cluster of plants, as zinc sulfate.…”

This study aimed to select regression equations based on the correlation between chlorophyll index and leaf nutrient contents, for real-time prediction of the nutritional status of 'Prata' banana. Six cultivars of 'Prata' banana were used as treatments, with five replicates and four plants per plot, arranged in a completely randomized design. Nutrient levels were evaluated based on laboratorial analysis and chlorophyll indices using a portable chlorophyll meter, in the third leaf from the apex to the base. Data were subjected to analysis of variance, calculating the correlations between leaf nutrient contents and chlorophyll indices, and the regression equations were adjusted to the associations that were significant and with greater magnitude. The selected models estimate leaf nutrient contents and allow a real-time, low-cost reliable prediction of the nutritional status of 'Prata' banana. It is an auxiliary technique that, combined with leaf and soil analysis, contributes to a more precise and secure nutritional evaluation.

“…Outrossim, a reposição pela ciclagem também contribui, como constatado em trabalho com 'Prata-Anã' onde 82% do Cu absorvido pela planta pôde retornar ao solo (HOFFMANN et al, 2010a). Donato et al (2010) obtiveram teores semelhantes para as bananeiras 'Prata-Anã' e 'BRS Platina' com suprimento de cobre via rizoma, bem como Nomura et al (2011), enquanto Damatto Junior et al (2011a) observaram maiores teores de Cu na folha com a aplicação de composto orgânico, durante o quarto ciclo de produção.…”

“…Na fase vegetativa, foram aplicadas no primeiro ciclo, 40 g de ácido bórico, 60 g de sulfato de zinco e 80 g de ureia por máquina costal, e a cada 60 dias, 10 g de sulfato de zinco e 10 g de ácido bórico via rizoma. Sulfato de cobre (3 g família -1 ) em três doses e 30 g família -1 de sulfato de magnésio durante o segundo ciclo (RODRIGUES et al, 2007;NOMURA et al, 2011).…”

Objetivou-se com este trabalho avaliar o estado nutricional e características agronômicas de bananeiras tipo prata sob adubação orgânica, no quarto ciclo de produção, em solos de elevada fertilidade construída. Os tratamentos, duas cultivares (Prata-Anã e BRS Platina) e cinco doses de adubação compostas por esterco bovino e farinha de rocha Naturalplus® foram dispostos em esquema fatorial 2 x 5, em delineamento em blocos casualizados, com três repetições. Foram avaliados: os teores de nutrientes nas folhas; altura de plantas; perímetro do pseudocaule; número de folhas; massa do cacho (kg) e pencas (kg); massa média das pencas (kg) e fruto (g) e massa das cinco primeiras pencas (kg); número de pencas; número de frutos por cacho e penca; massa (g), diâmetro (mm) e comprimento interno e externo do fruto (cm). Doses crescentes de K2O incrementam os teores de N, P e Cu para cultivares Prata-Anã e BRS Platina, que diferem entre si quanto aos teores de Fe, Zn e S. A ‘Prata-Anã’ se destaca com número de folhas e frutos por penca, enquanto a ‘BRS Platina’ maior massa média das pencas e do fruto e comprimento do fruto. As doses aplicadas não influenciam a produção das cultivares BRS Platina e Prata-Anã no quarto ciclo em solos de elevada fertilidade construída.Palavras chave: farinha de rocha; esterco bovino; sustentabilidade. PHYTOTECHNICAL AND NUTRITIONAL CHARACTERISTICS OF BANANA SUBMITTED TO FERTILIZER SOURCES FOR ORGANIC MANAGEMENT ABSTRACT:The objective of this work was to evaluate the nutritional status and agronomic characteristics of silver - type banana under organic fertilization, in the fourth cycle of production, in soils with high fertility. The treatments, two cultivars (Prata-Anã and BRS Platina) and five fertilizer doses composed of bovine manure and Naturalplus® rock flour were arranged in a 2 x 5 factorial scheme, in a randomized block design, with three replications. Leaf nutrient contents were evaluated; plant height; perimeter of the pseudostem; number of leaves; mass of the bunch (kg) and hands (kg); average mass of the hands (kg) and fruit (g) and mass of the first five hands (kg); number of leaves; number of fruits per bunch and hands; mass (g), diameter (mm) and internal and external length of the fruit (cm). Increasing doses of K2O increases N, P and Cu contents for Prata-Anã and BRS Platina cultivars, which differ in Fe content, Zn and S. The ‘Prata-Anã’ stands out with the highest number of leaves and fruits per hands, whereas the 'BRS Platina' presents higher average mass of the fruit and the length of the fruit. The applied doses do not influence the production of the cultivars BRS Platina and Prata-Anã in the fourth cycle in soils with high constructed fertility.Keywords: rock dust; bovine manure; sustainability.

“…However, the low mobility of B in plant tissues may constitute an impediment to plant nutrition, being necessary many applications. On the other hand, unlike micronutrients fertilization in soil, foliar fertilization allows more uniform applications per unit area and relatively faster responses, when the crops are in advanced stages of development, and it is possible to correct any deficiencies in the short term (Nomura et al, 2011, Lemiska et al, 2014. Therefore, it was expected that the application of B in the foliar tissue, being a fertilization closer to the reproductive stage could influence positively the grain yield, however, it was inferior to the application in the soil.…”

Boron is one of the most limiting micronutrients in grains production system in Brazil. In this way, the objective was to evaluate the effect of forms of application and doses of boron in irrigated wheat grain yield evaluating the economic terms in Cerrado region. The experiment was conducted in no-tillage system in an Oxisol with clay texture in Selvíria, MS, Brazil. The experimental design was a randomized block design with four replicates, arranged in a 4 × 3 factorial scheme: four doses of boron (0, 1, 2 and 4 kg ha -1 ) with boric acid source (B = 17%); and three apllication forms: a) in desiccation of the predecessor straw, together with herbicide; b) at the time of sowing, in soil along with the formulated fertilization seeding and c) via leaf tissue with the application of post emergent herbicide. The application of 2 kg ha -1 provides greater grain yields, but the highest economic return was obtained at the dose of 1 kg ha -1 , with application in soil, ensuring profitability from production of irrigated wheat in the Cerrado.
