The field phase was completed in the period of July 2018 - February 2019. The experimental site environment is humid tropic and the soil is deep silty loam, with medium fertility and good drainage. The objective of the research was to study the behavior of the banana in early stages of the growth of the selected shoots for production against increasing doses of potassium fertilization. The doses used were: 0, 200, 400, 600 and 800 kg of K2O, such application was distributed monthly from the moment the banana shoots had around two months old. The treatments were distributed in the field according to a completely randomized design (DCA). For the separation of the averages the Duncan test (0.05) was applied. For the evaluation of the shoots growth until their complete vegetative development, data of the following variables were recorded: plant height, which reached an average of 2.95 m, being the top height among the others treatment, pseudostem circumference, which presented an average of 0.725 m, higher to the other treatments, leaf area, which obtained an average of 2.10 m2 and leaf emission rate with an average of one leaf for week, all these variables were influenced by the 600 kg dose of K2O, in addition data of the concentration of N, P and K were recorded without replications. All the variables responded positively to potassium fertilization. The foliar K concentration increased with increasing doses of potassium fertilization. The response of any of the analyzed variables was adjusted to a polynomial model, more than 90% of the variation of the mentioned variables, with one exception, was explained by the variation of the doses of potassium fertilization. |
