Efeito de diferentes lâminas de irrigação sobre a população de Meloidogyne javanica e a produtividade de bananeira no norte de Minas Gerais

Abstract

The present work aimed to assess in the field the effect of irrigation different levels (100%, 125%, 150% and 175%) determined by evapotranspiration from the tank class A (ETtca), on the population of Meloidogyne javanica in the soil, banana productivity and number of days needs for flowering and yield of Prata-Anã cultivar of banana on the North of Minas Gerais state, Brazil. The number of second stage juveniles of M. javanica increased reaching the maximum J2 level at 118% of ETtca. The irrigation levels, 125, 150 and 175% ETtca increased the banana productity in kg/ha-1 significantly as compared to 100% level. However, no effect was observed on the number of days for flowering and for harvesting of Prata-Anã banana.
