Nitrogen (N) influences the grain yield and protein content of barley grown for malt. This work aims to determine the effect of N rate on grain yield and protein content and many other agronomic traits of Pewter barley cultivar. The field trial was carried out in Cartaxo, in a completely random design with 4 N rates [0 (N0), 100 (N100), 150 (N150) e 200 (N200) kg N ha-1], applied as ammonium nitrate, and 4 replications. The treatments influenced tillering and total dry matter yield. The number of ears per plant and area increased with N rate. The dry weight of the ears decreased at N200 treatment. Grain yield followed a quadratic model, reaching the maximum value at N150. The treatments did not significantly influence the weight of thousand grains and specific weight. The SPAD (Soil and Plant Analysis Development) values were inconclusive. The protein content in the grain was lower than required by industry.
