The objective of this research was to study the effects of 5 doses of 4 different types of biofertilizer in production of banana Nanicão in 3 successive cycles. The experiment was conducted under field conditions at Escola Agrotécnica of the Cajueiro in the municipality of Catolé do Rocha, in the state of Paraíba, Brazil. The soil in the area is classified as Entisol with sandy loam texture. The experiment was conducted during June 2008 to June 2011. The experimental design was a randomized block design with 20 treatments in a 5x4 factorial scheme (doses x types) of biofertilizers with four replications. The results show that the types of biofertilizers did not affect the production quality, the length and diameter of fruit increased with increasing dose of biofertilizer to optimum limits, the length of the fruit of the second cycle was more than that of plants of first and third cycles , the diameter of the fruit of the second cycle of the crop was higher than the first and third cycles and values of ºBrix and pH of the pulp of the fruit were not affected by biofertilizer doses.
