Field experiments with winter wheat cultivar 'Sirvinta 1' and 'Alba' were conducted over 1991-1993 in Luksiai (Lithuania). Winter wheat was treated with ammonium nitrate (0...120kg/haN) in one, two or three dressings in spring at the beginning of the vegetation, at the beginning and the middle of the stem elongation and at the flag leaf stage. Winter wheat 'alba' was more resistant to the diseases investigated than 'Sirvinta 1'. Nitrogen fertilizers increased development of powdery mildew, rust and root rot and has no significant influence on septoria. Yield of winter wheat 'Alba' was higher than yield of 'Sirvinta 1' in plots without fungicides, but on the plots with fungicides yield of both varieties was on the same level.
