A field experiment was conducted with eight treatments comprising of farm yard manure (@ 20t/ha), vermicompost (@ 2t/ha), Trichoderma viride (@ 10g/pit), Paecilomyces lilacinus (@ 10g/pit), neem cake (@ 500 kg/ha), vine dipping in monocrotophos (at 1000ppm for 6hours), carbofuran 3G (@ 1 kg a.i./ha) and untreated control in different combinations at Simanta Seed farm, Kalyani of Bidhan Chandra Krishi Viswavidyalaya, Nadia, West Bengal. Experimental results revealed that VD + Trichoderma viride at 10 g/pit (in two split doses) was superior to all the treatments and this was followed by VD + vermicompost at 2t/ha, vine dipping (VD) with monocrotophos 36SL at 1000 ppm for 6h + decomposed organic matter @ 20t/ha. Adoption of vine dipping in monocrotophos 36SL at 1000 ppm followed by soil inoculation of T. viride at 10g/pit once at planting and second dose at 40 days after planting reduced root galling caused by M. incognita and gave fruit yield almost double of the untreated plots. No effect of nematode attack on fruit size and weight was observed.
