Paper Title
Impact of Fly Ash on Population Density and Reproduction Factor of Root-Knot Nematodes Parasitized Tomato

Abstract
Females, juveniles(J2& J3 + J4) and root population of root-knot nematode (Meloidogynejavanica) in tomato roots were increased gradually upto50% fly ash addition to the soil through artificial treatment conditions. However onward to 50%, fly ash amendments wereproved detrimental to all parameters studied except the nematode density in terms of soil and total population which decreasesprogressively in onward fly ash treatment.All the studied nematode parameters were nil at 80 to 100% fly ash added treatments. Nematodeinoculum level was also proved an important determinant for the nematode multiplication (i.e. build up) and reproduction. All the parameters, referred to above were found maximum at 3000 nematode inoculum levels(except reproduction factor) irrespective of the presence or absence of fly ash. But at 4000 and 5000 nematode inoculum levels, the nematode population was somewhat masked but were still greater than 1000 and 2000 levels. However Reproduction factor (Rf) decreased gradually with gradual increase in the inoculum level. Keywords— Root-Knot Nematode, Fly Ash, Total Population, Reproduction Factor, Inoculum Levels
