Abstract
An experiment was conducted at the Central Research Farm of Bidhan Chandra Krishi Viswavidyalaya, Gayeshpur, Nadia, West Bengal to study the plant mediated interaction effect of Root knot nematode and sucking insects (aphid & whitefly) infesting tomato plants. The whole experiment was laid out in split plot design, with three main plots of different levels of fertilizer regimes i.e. recommended doses of fertilizer, 75% of the recommended dose and 50% of the recommended dose and four sub plots of different levels of pest infestation i.e. only root knot nematode, only insects, both root knot nematode and insects and the plot in which plants were subjected to no pest infestation. The plant growth attributes such as chlorophyll SPAD value, length, fresh weight and dry weight of shoot and root and yield were recorded. The study revealed that the observations taken for plant growth attributes and yield were comparatively higher in the plots with no pest infestation and were the lowest in the plants subjected to infestation by both root knot nematode and sucking insects. The interaction effect between different fertilizer regimes and different pest infestation was significant for all plant growth attributes and yield. The populations of these pests were lower in plants infested by both as compared to the plants subjected to sole infestation of these pests.
