Abstract
Results of a two-year field investigation on the presence and seasonal variation of the plant-parasitic nematodes in the rhizosphere of rape in 4 commercial fields in the region of eastern Slavonija (Croatia) are shown in this paper. A total of 11 genera were identified with in which 12 plant-parasitic species of the nematodes. Some differences in a structure and relating population density of nematodes have been recorded during the rape growing season in all investigated fields. More individuals, as well as greater number of the nematodes genera, have been found in the begining of the rape growing season (autumn) than later (spring). Nematodes of Aphelenchus and Tylenchus genera have been found in 96% of all the examined soil samples. The above mentioned genera have been the most frequent and dominant ones as of the total number of found nematodes, having partaken of 62%.
