Abstract

The objective was to evaluate the effects of nitrogen fertilization in coverage with concentrated solution and other conventional sources or protected against losses due to volatilization in corn plants. The experiment was conducted in a randomized block design, with six treatments and four replications. The treatments were composed of five nitrogen sources: Conventional Urea® (46% N); Ammonium Sulphate® (20% N); Urea NITRO GOLD® (37% N); Urea NITRO MAIS® (44% N); and Solution of Urea® (urea in water 1: 5), applied in cover without incorporation in the soil, plus the control. Nitrogen fertilization had little influence on plant height, stem diameter and leaf area. The production components that had the greatest influence on productivity were the number of grains per row and the number of rows per ear. Nitrogen fertilization of cover increased productivity and all sources were efficient to improve the productivity of the corn crop.
