Seven genera of nematodes were isolated from the soils of acid lime gardens of SPSR Nellore district. Meloidogyne spp., Longidorus spp., Trichodorus spp., Rotylenchulus spp., Xiphinema spp., Helicotylenchus spp., and Tylenchulus semipenitrans. The most predominant genera were Tylenchulus semipenetrans which recorded highest absolute frequency (89.57), absolute density (750.3) and highest prominence value (7100.90) followed by Meloidogyne spp. The highest nematode population of 4200 nematodes/kg soil and 538/gm root sample was recorded in the gardens of Balayapalli mandalam followed by Dakkili, Rapur and Podalakur mandals of Nellore district.
