Abstract

A survey of vegetable crops in Biswanath district of Assam was conducted during April 2021 to December 2022 to record the plant parasitic nematode community structure. Six species of plant parasitic nematodes viz., Meloidogyne sp, Helicotylenchus sp, Hoplolaimus sp., Tylenchorhynchus sp., Xiphinema sp. and Pratylenchus sp., were isolated and identified from 100 soil samples collected from rhizosphere of different vegetable crops. Analysis of nematode communities revealed that among the plant parasitic nematodes Meloidogyne sp. was predominant and encountered in most of the samples with 93% frequency of occurrence followed by Hoplolaimus sp. (90%). The lowest frequency was recorded in case of Pratylenchus sp. (14%). Meloidogyne sp. had the highest density of 235.29 numbers followed by Hoplolaimus sp. (135 nos.). Among the community of plant parasitic nematodes, Meloidogyne sp. was found to be most prominent with highest prominence value (22.69) followed by Hoplolaimus sp. (12.80) and Pratylenchus sp. was the least prominent (0.57).
