Níveis de nitrogênio, potássio e água para a bananeira CV. ́Prata Anã’ cultivada no norte de Minas Gerais.

Abstract

The work had as objective to evaluate yields of banana cv. Prata Anã for five levels of Nitrogen, potassium and irrigation depths. The experiment was carried with 15 treatments following a random block design, with three replications, according to a Plan Puebla experimental matrix. The factors were irrigation depth (LI), N and K doses. There were five levels for each factor. Irrigation was applied daily and N and K by irrigation water. A variance analysis was performed concerning bunch yield and number of fruit per bunch for a period of harvest of 03/31/2004 to 03/31/2005. The dependent variables were more sensible to application of nitrogen and irrigation water than to potassium application. The application of 378 kg/ha of N, 432 kg/ha of KzO and 105%ETc was the most adequate for the banana crop under the experiment conditions.
