| Abstract: | The numbers and species of phytoparasitic nematodes on soybean were studied over several years in Croatia, especially in the regions of Slavonija and Baranja. 19 phytoparasitic species were found, and of these Pratylenchus spp. predominated. These nematodes were found in mixed populations and their numbers were, at times, enormous. The average number per 100 ml of soil was about 100 individuals, with a maximum of 3348. The relationship between the number of nematodes and yield of soybean was calculated by a single regression equation. The soybean cultivars Sava and OS-88 apparently possess tolerance to relatively high numbers of Pratylenchus spp. in the rhizosphere. |
