The soil conditions, climate, topography and adapted varieties have favored the cultivation of wheat in the 'Cerrado'. However, regarding the nitrogen fertilization, it is considered the main factor for increasing production. The objective of this study was to evaluate the initial development and dry mass production of wheat plants cv. Guamirim fertilized with nitrogen in the 'Cerrado' Oxisol. The experiment was carried out in a greenhouse at the University of Mato Grosso - Campus of Rondonópolis, in recipients of 5 dm³. The experimental design was completely randomized with six levels of nitrogen (0, 80, 160, 240, 320 and 400 mg dm-3), five replications with five plants per pot. The evaluation periods were: 26, 33, 40 and 47 days after emergence, where the number of leaves and tillers, plant height, dry mass of shoots and roots were determined. Nitrogen fertilization affected the wheat plant development for all evaluated periods. The best responses of wheat to nitrogen fertilization occurred at doses ranging from 80 to 195.6 mg dm-3.
