Abstract

A study was conducted to find out the effect of various fodder crops such as Stylo (Stylosanthes gracilis), Pusa Giant Napier, NB-21, and Guinea grass (Makueni) on the population build up of the nematode fauna in a sandy loam area. Samples were drawn in August, 1979, July and October, 1980. These crops were found to have no significant effect on the population build up of nematodes on coconut, Radopholus similis was recorded only from coconut roots whereas Pratylenchus zeae was recorded from roots of all fodder crops but not from coconut. Tylenchorhynchus coffeae was occasionally recorded from coconut roots. In general the following nematode species viz. Aphelenchoides sp., Aphelenchus (Anaphelenchus) isomerus, Ditylenchus sp., Cricollemoides sp., Helicotylenchus abunaamai, Hemicriconemoides brachyurus, Hoplolaimus seinhorsti, Longidorus saginus, Meloidogyne sp., Pratylenchus zeae, Paratrichodorus acaudatus, Rotylenchulus reniformis, Tylenchorhynchus coffeae and Xiphinema elongatum were recorded from all the treatments in small numbers.
