Description The root-lesion nematode, Pratylenchus co//eae is
considered to be one of the most economically important
nematode pests of banana. Surveys carried out in
banana growing regions in different parts of India having
different soil types indicated variations in population
level and percentage of infestation of P. co//eae (Rajendran
et al., 1979; Sundararaju, 1996). An attempt was
made to investigate the influence of different soils on
the nematode host interactions.
The effect of different soil types (alluvial, sandy loam, silty clay, black soil, laterite and red soil) on the multiplication of
Pratylenchus coffeae and growth of banana plants was studied. The results revealed that maximum shoot length, girth at collar,
number of leaves, number of roots, root length and root weight were evident in alluvial soil followed by sandy loam soil, whereas
minimum plant growth parameters was recorded in red soil. Maximum root-lesion index was observed in silty clay soil (4.4) and
alluvial soil (4.2) whereas minimum infestation was observed in red soil (3.2). The reproduction factor of nematode population
based upon root-lesions and final root and soil population was maximum in silty clay soil followed by alluvial while minimum nematode
population was recorded in red soil. The multiple regression equations pertaining to the soil physico-chemical properties
versus nematode populations in both soils and roots were derived.
