Corn (Zea mays L.) is grown throughout the world, and is an important crop for Brazilian agribusiness, and subsistence farmers. The application of fertilizer can be manipueira as foliar or soil, and the leaf is more feasible because besides being a source of additional nutrients may serve as a pesticide, or may have double effect. The present study aimed to analyze the use of cassava as a foliar fertilizer in corn. The experiment was done under field conditions between the months of June and August 2010 in the municipality of Lagoa Seca, Paraíba and was laid in randomized block design, with five treatments, and four replications. Plant height, insertion height of first spike, stem diameter and length, number of leaves and leaf area were determined 90 days after planting. The data were subjected to analysis of variance and polynomial regression, by using the F test to assess the significance. The application of different strengths of manipueira resulted in increased biomass in all variables (p < 0.01). The manipueira proved to be an efficient fertilizer, when applied to corn leaves.
