Biofertilizer application provides positive responses of several vegetable crops. The effect of foliar application of liquid biofertilizers on seedling and on commercial production of lettuce cultivar Vera were evaluated from October 2005 to January 2006. Seedling production was carried out in a nursery specialized in the production of vegetable seedlings, in Uberlandia, Minas Gerais State, Brazil, and the crop growing was carried out at a field of the Universidade Federal de Uberlandia. Plant height, number of leaves, aboveground part fresh weight and root diameter were evaluated on seedlings and fresh weight of the aboveground part and roots were evaluated on plants in the field. Aminoagro Raiz, Aminoagro Folha Top, Aminoagro Mol, Nobrico Star, Aminolom Foliar and Lombrico Mol 75 were the assessed biofertilizers. The first experiment using seedlings was arranged in a completely randomized design with 15 replications and the second one, which was carried out in the field, was in randomized blocks with four replications. The solely use of liquid organomineral biofertilizers, via foliar application, was superior in comparison to the control treatments for most of the evaluated variables at the plantlet and field stages.
