Susceptibility of two maize cultivars to diseases and pests depending on nitrogen fertilization and on the method of magnesium application

Summary. Studies were carried out in order to investigate the reaction of two types of maize cultivars to the infection by diseases and pests depending on nitrogen fertilization and on the method of magnesium application. Both in case of diseases and pests, only the number of plants was recorded which were damaged or infected by a given pathogen and the result was expressed by the percentage of damage or infestation. The two studied maize cultivars showed different susceptibility to infestation by pathogens. It was found that the size of the applied nitrogen dose modified the infection of maize plants by fusariosis disease and exerted an effect on the extent of feeding by frit fly and European corn borer. The use of magnesium and the method of its application did not exert any effect on maize reaction to diseases or pests.

Key words: maize, cultivar types, diseases, pests, nitrogen, magnesium
