abstract
A survey was carried out to study the distribution of plant parasitic nematodes associated with forage crops in different places of Bhubaneswar of state Odisha, India. Around 140 soil samples were collected from the rhizosphere of forage crops (Hybrid Napier, Maize, Cowpea, Lemongrass, Bajra, Rice bean, Guinea grass) across the different 5 places of Bhubaneswar. Nematodes were isolated by Cobb’s sieving and decanting method followed by Modified Baerrmann’s funnel technique. Estimation of mean nematode population per 200 cc soil samples revealed the presence of Rotylenchulus reniformis, Tylenchorhynchus mashoodi, Pratylenchus zea, Xiphinema insigne, Caloosia heterocephala, Helicotylenchus dihystera, Hoplolaimus indicus, Aphelenchus avenae, Criconemalla ornate, Rhabditids, Mononchids, Mylonchulus, Dorylaimid exhibiting varying population densities. Among the different plant parasitic nematodes Xiphinema insigne was highest frequency of occurrence 110.00 with Absolute frequency (78.57%) followed by Hoplolaimus indicus (75.71%). More over Rotylenchulus reniformis was found the most prominent species with highest prominence value (80.60) followed by Xiphinema insigne (60.59), with the lowest prominence value (2.47) recorded in Criconemalla ornata. Among free living nematodes Rhabditids were the highest frequency of occurrence (136.00) with absolute frequency (97.14%) followed by Dorylaimid (94.29%). Rhabditids were also having the highest prominence value (86.78) followed by Mononchid, Dorylaimid and lowest Mylonchulus (19.61).
