Identification of ‘Prata anã’ banana leaf to diagnose the level of phosphorus sufficiency Rev. Bras. Frutic.
Silva,José Tadeu Alves da; Rodrigues,Maria Geralda Vilela.
Abstract The aim of this study was to identify the leaf and its part with greater sensitivity to detect P variation in the ‘Prata anã’ banana plant. The experiment was carried out in Montes Claros, Minas Gerais, in a clayey Oxisol. A randomized complete block design was used, with six P doses (0, 50, 100, 150, 200 and 250 g family-1 year-1 of P2O5) and four replications. In the plants beginning the emission of the bunch in the first, second and third cycle of the banana tree, the 3rd and the 7th leaves were collected from the apex, from where 10 cm of the center of the limbs were removed, eliminating the midrib, 10 cm of the petiole and 10 cm from the midrib and 10 cm from the 1 leaf limbs. The midrib of the third leaf showed greater sensitivity to detect...

Dias,Jairo Rafael Machado; Wadt,Paulo Guilherme Salvador; Partelli,Fábio Luiz; Espindula,Marcelo Curitiba; Perez,Daniel Vidal; Souza,Fábio Régis; Bergamin,Anderson Cristian; Delarmelinda,Elaine Almeida.
Abstract: The objective of this work was to determine reference values for evaluating the nutritional status of 'Pêra' orange trees in different fruiting stages, using the compositional nutrient diagnosis (CND) method. The study used 243 leaf samples from 81 plots, with samplings performed in plants bearing fruits with three and six months of age, and also in the main harvest (nine months). Plots with productivity higher than 30 Mg ha-1 were selected for the establishment of reference standards. Three normal ranges were evaluated for each nutrient in the reference population, comprehended by the confidence interval (CI) of the foliar content averages, by the mean±standard deviation (±SD), and by the mean±⅔SD. Regardless of the normal range of nutrients...
