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. |
