Detailed materials and methods of the experiment were published in the first part of the paper [Prusiński 2006]. The greatest increase in bean seed yield observed when the intensity of bean cultivation technology becoming more intensive resulted from increasing pod density. The increasing N doses in the successive technologies resulted in significant decrease average agricultural (Er) and physiological (Ef) effectiveness. The N consumption index amounted to 77%. Increase in the intensity of bean technology resulted in an increase in the value of seed production, direct costs and direct surplus. The greatest direct surplus – 64% for cultivars was obtained when intensity of technology increased from the extensive to integrated technology. Further intensification of bean technology gave lower direct surplus increase. The marginal analyses of costs revealed that the semi-intensive technology was justifiable for common bean cultivation for seeds.
