Getting new knowledge about relations between content of semi leafless variety of pea cultivated in a mixture with spring wheat and the level of nitrogen fertilization was the aim of the research work. In order to determine the amount of biologically fixed nitrogen by pea cultivated in a mixture with wheat a special OECD method for nutrient balance calculation on the field level was used. The biggest yields of seeds were observed in 1998 - year with the most favourable distribution of precipitation. Significantly smaller by about 35 percent yields were observed in 2000 - year in which drought and high temperatures appeared (in time of flowering of pea and earing of wheat)
