Both for winter and spring barley, for the main area of use - brewing - of particular importance is their quality.The main elements of quality under the influence of fertilization were followed in eight varieties of winter and spring barley in two areas with different climatic conditions, Timişoara and Mizieş - Bihor. Were determined: dry matter, starch, crude protein, fat, ash, power of germination (germination energy), extract. The research was conducted in two areas with different climatic conditions, Timişoara and Mizieş - Bihor. In both centers, four varieties of spring barley were studied: Aspen, Adonis, Penellope and Hanca and four varieties of winter barley: Laura, Trasko, Plaissant and Clarine. The research aimed to determine the influence of fertilization on yields. Four variants of fertilization were used: N 48 P 48 K 48 ; N 48 P 48 K 48 + PlantfertU; N 48 P 48 K 48 + MicrofertU and N 48 P 48 K 48 + TerraSorb. The variant N 48 P 48 K 48 was used as control. Foliar fertilizers were applied during vegetation before earing. Research shows that both the studied varieties and the fertilization variants strongly influence the quality of barley. The results show that climatic conditions are essential not only for production but also for its quality, the qualitative values are different in the two research centers. In Timisoara in 2005-2007 grains protein content (raw material) to the four studied varieties are within 8.37 and 9.44. Compared to dry substance, the range of protein content is between 7.51 and 8.45%. Under the influence of the agrofond, protein content of barley and two-row barley grains varies between 8.84% on the agrofond where foliar fertilizer Terra Sorb Foliar was used overlapped on a basic agrofond N 48 P 48 K 48 and 9.14 on the agrofond N 48 P 48 K 48 - without foliar fertilization. Analysis of protein content in barley and two-row barley grains (raw material) in the interaction between the experimental factors (variety x agrofond) is found that commonly at all barley and two-row barley studied varieties, foliar fertilizers causes a lower protein content than the one made on witness agrofond N 48 P 48 K 48 .
