Thus, it is urgent to invest in the development of production system of this cereal, to attend the national plan of food production as well as to prevent revenue expenditures abroad. Nitrogen is an important component of wheat production, second only to water. In this work it is described the results of an experiment whose objective was to evaluate the response of wheat to N fertilization in area of the Nacala Corridor. Experimental design was a randomized block encompassing five treatments, corresponding to rates of 0, 40, 80, 120 and 150 kg N/ha. N source was Urea, with 45% N. Each treatment was replicated four times in the field. Experimental units covered 8.4 m2 (1.4 x 6 m), in lines spaced 0.2 m. Evaluations were made within a useful area of 1.8 m2, encompassing the three central lines (0.6 m wide) and 3 m of length. Wheat cultivar was BR 18, which is adapted to tropical savannas conditions. The N rate estimated for maximum yield of grains, 2.075 kg/ha, was 140 kg N/ha. The maximum technical efficiency was estimated with the economical rate of 78 or 104 kg N/ha, corresponding, respectively, to 1.868 and 2.006 kg/ha of grains.  aCerrado  aNitrogênio  aTrigo  aMoçambique1 aMUTADIUA, C.
