The effect of mineral N fertilization on the yield of seeds and the contents of protein, ash, fat and fibre in field beans Dino was investigated in 1992-1995. The field bean seeds came from experiments carried out in the Carpathian foothill region in the em :rons of Rzeszów. The results of investigation proved that N fertilization 0-80 kg/ha effected an increase of seeds yield and incerease protein content and fat but decrease fibre content in seeds. The highest fertilization effect as protein yield and content was obtained at 20 kg N/ha dose calculated on 1 kg N. Seed variety Dino had lower protein content and higher of fibre and ash and higher protein yield in comparison to Nadwiślański variety.
