The objective of this work was to evaluate nutrient leaf contents and the productivity of 'Prata-Anã' banana submitted to different irrigation systems, during the first production cycle. The experimental design was in randomized blocks, with six treatments in 3x2 factorial arrangement: three irrigation systems (conventional sprinkler, microsprinkler and drip); and two genotypes (Prata-Anã and its hybrid PA42-44). Four replicates were used in a 3.0x2.5-m spacing. The evaluations were done at 90, 180 and 360 days after planting. The genotypes and the irrigation systems showed significant interaction for leaf contents of B and Cu, at 180 days after planting; and the genotypes differed from each other for leaf contents of N, P, K, Ca, Mg, Cu and Mn, independently of the irrigation system used. Nutrient leaf contents occurred in sufficient levels or above them. The lowest micronutrient leaf contents occur under drip irrigation. The genotypes have similar yield under the different irrigation systems.
