Jute followed by rice is the most common crop sequence adopted by the growers in West Bengal. Community analysis of plant and soil nematodes revealed the Meloidogyne graminicola ranked first in prominence value followed by Hirschmanniella spp., in rice whereas in jute, M. incognita was predominant followed by Hoplolaimus indicus and Rotylenchulus reniformis. Other plant parasitic nematodes genera were also prominent member of nematode community but less important as plant parasites of crops. Among the fifteen species encountered in jute-rice cropping system, M. graminicola, Hirschmanniella oryzae, H. mucronata, Hoplolaimus indicus, Pratylenchus coffeae, P. brachyurus in rice and M. incognita, . javanica, R. reniformis and P. coffeae in jute, were thought to be potential plant pathogens to cause substantial yield losses. Saprozoic nematodes were the most prominent member of the soil nematode community but their role in crop production system is still not clearly known.
