Impact of stubble intercrop and organic fertilisation on the health status of spring barley culm base

The research aimed at defining a regenerating effect of stubble intercrop fertilised with cattle slurry and wheat straw on the value of spring barley stand. A strict field experiment, set up as a randomised split-plot design, was carried out over 1996-2000 at the Mochełek Experiment Station, in the Kujawy and Pomorze Province. White mustard, radish, winter rape, sunflower and blue phacelia were sown as stubble intercrops. The culm disease infection was defined on barley culm base. Bipolaris sorokiniana and Fusarium genus fungi, F. culmorum especially, constituted the greatest, while Pseudocercosporella herpotrichoides and Rhizoctonia spp. much lower threat for barley. There was shown a favourable effect of fertilising on the barley culm base health status.
