Rice is one of the most important food crops in the world. In India, rice contributes 43 per cent of the total food grain production and 46 per cent of the total cereal production. Rice crop is affected by many fungal, bacterial, viral and nematode diseases. Among the nematodes, rice root knot nematode (M. graminicola) is considered as a major problem in rice crop. In present study, a pot experiment was conducted to test the efficacy of oil cake against rice root knot nematode. In this experiment, eight oil cakes viz. Neem, cotton, linseed, groundnut, sunflower, sesamum, mustard and mahua oil cake were taken. It was observed that many tested oil cake significantly reduced the galls/plant. Among all the cakes were found most effective against nematode infestation in rice root, at the 60 DAS, minimum 1.89 galls/plant were recorded, when mahua cake was applied at @ 50 gm/5kg soil, whereas in control pot 14.44 galls/plant was recorded. Most of tested oil cakes were also found effective in increase for the growth parameters (shoot length, root length, shoot weight and root weight) of rice plant.
