Two series of pot experiment were carried out in 2002-03 and 2003-04 to determine the response of 8 new spring barley cultivars to three nitrogen rates: 1, 2 and 3 g N per pot. The Barke, Jersey, Bolina, Hanka and Tolar cultivars showed significant increase of grain yield with increase of N rate to 3 g per pot. For the remaining cultivars, significant differences of yield increase were observed between the doses of 1 g N and 2 g N per pot, the yields at 2 and 3 g N per pot were similar. The grain yield increment was related to increase of productive tillering rate. All cultivars showed great increase of protein content in grain with increase of N rate, as well as protein yield increment
