Abstract
Female and juvenile numbers (J2& J3 + J4) and root population of root-knot nematodes (Meloidogyne javanica) in tomato roots were increased gradually up to 40% composted rice husk addition to the soil. However, onward to 40%, husk amendments were proved detrimental to all. Nematode density (in terms of soil and total population) and reproduction (in terms of reproduction factor i.e. the ratio of final to the initial nematode population) decreased progressively with increasing soil husk amendments. All the above studied nematode parameters were found nil at 90 and 100% husk added treatments. Nematodeinoculum level was proved an important determinant for the nematode multiplication and reproduction. All the nematode parameters, in above terms, were found maximum at 3000 nematode inoculum level (except reproduction factor) irrespective of the presence or absence of rice husk. But at 4000 and 5000 nematode inoculum levels, the nematode population and reproduction were somewhat masked but were still greater than control (i.e. nematode uninoculated treatments). However Rf was decreased progressively with gradual increase in the inoculum level.
