Root-knot nematode (M.
) constitutes one of the important nematode pests on cowpea (Vigna
). The edaphic factors of soil such as soil texture play vital
role in determining the severity of diseases caused by plant-parasitic

Screen house studies were conducted in 2013 and 2014 using 15cm
size plastic pots (one kg capacity) having soils of five different textures
(clay, clay loam, sandy loam, loamy sand and sand) on root-knot nematode (M.
) at          one J2/g
soil in cowpea (c.v. Ife brown) was undertaken. Under each soil type, nematode
inoculated and non-inoculated checks were kept. The observations recorded 60
days after nematode inoculation revealed that maximum and significantly higher
shoot length, fresh and dry root and shoot weight, number of leaves and buds/plant
were in sandy loam soil while these growth parameters were minimum and
significantly lower in clay loam soil irrespective of nematization.

The reproduction factor of M. incognita based
upon galling, fecundity and final soil populations was maximum (30.6) in sandy
soil followed by loamy soil (25.8) while it was minimum (3.5) in clay soil
making it least favourable for the nematode. With this result it shows that
Sandy soil is highly favourable to M. incognita reproduction
which is followed by loamy soil and the least favourable was clay soil to the
nematode reproduction.
