• Abstract:

  White oats are one of the main winter cereals produced in Brazil due to its multiplicity of purposes (soil cover, animal feed, green manure, human health). Its productivity is related to management technologies, among which nitrogen fertilization stands out. Therefore, the objective was to evaluate the biometric parameters of white oats under different doses of nitrogen. The experiment was carried out in soil classified as Red Latosol in the municipality of Palmeira das Missões, RS. The treatments consisted of five doses of nitrogen (0, 50, 100, 150, 200 Kg/ha-1) in the form of urea applied in coverage at the beginning of tillering distributed in experimental plots of 3.0 m x 4.0 m, in a Latin square design (DQL) with five replications (25 treatments). The biometric parameters of the plant were analyzed: height, number of tillers, growth rate (TC), leaf width, fresh mass production (MFPA) and dry mass of shoots (MSPA). Oats had their performance favored with nitrogen fertilization doses between 100 and 150 Kg/ha-1.
