Abstract

The source material were the results of surveys carried out in 2008–2011. Every year about 500 farms were surveyed. Data were collected from 4760 fields with a total area 25.4 thousands hectares. The differences in yield depending on used seeds were compared. The significance of differences between yields, depending on used seeds, (certified or uncertified) was assessed using Fisher’s test. A significant increase of yield in fields where certified seed were used has been proven. The increase in yields, depending on the species, ranged from 12% for triticale to 23% for rye and in absolute units ranged from 4.89 dt·ha-1 for triticale to 7.59 dt·ha-1 for wheat.
