Four chicory cultivars were forced in water culture. During forcing
ultra-violet radiation of 254 nm, emitted by a 64 W lamp, was used for
constant water disinfection. The application of ultra-violet radiation for
water disinfection significantly increased the weight of feeding roots in
the studied chicory cultivars, this resulting in their better yield. The
yield of chicory heads (cvs. Atlas, Rinof, Rumba, and Salsa) forced in
disinfected water was significantly higher than that on control plots.
