Obtaining quality and economically motivated productions represents a desire that all farmers follow, and in the conditions of two-rowed barley culture, mineral fertilization often prevents them in its achievement. Taking into account the influence of fertilizers over the quality of the harvest, fertilization should be differentiated according to the purpose for which the culture is intended, feed or malt for brewing. In order to accomplish the theme entitled " Research on the influence of nitrogen doses and variety on the production of spring two-rowed barley (conv. Hordeum distichum) in the Western part of the country" research have been carried out on the territory of the Didactic Station of the Banat’s University of Agricultural Sciences and Veterinary Medicine “King Michael I of Romania” from Timisoara. The main objective of the research was to bring a contribution in determining the influence of doses and of the variety on production, leading to the achievement of economically efficient harvests with superior quality attributes. The effect of nitrogen doses, and of the variety on spring two-rowed barley, has been tested in a bifactorial experience, located on a cambic chernozem soil, phreatic moist. The results point out that nitrogen fertilization has influenced production, the highest value of 2733 kg/ha was obtained by the N100fertilization variant, with a production increase of 8 % compared to the control variant N40 (2532 kg/ha), and a harvest difference of 201 kg/ha, statistically ensured as a significant. By increasing the nitrogen dose from N40 to N80 production increased by 7%, with a significant harvest difference between the two variants of 196 kg/ha. Regarding the protein content, its lowest value was obtained in the fertilization variant N40, in the Kompact variety (10.68%), followed by the Cristalia variety (11.07 %) and the Annabell variety (11.39 %). The results obtained add originality in terms of fertilization and adaptability of some varieties of spring two-rowed barley, representing a viable source of information for spring two-rowed barley growers, who want to obtain high production, but also qualitative ones.
