Effect of different oil cakes along with bioagents/nematicide was evaluated on root knot nematode (Meloidogyne spp.) and root nodulation in lentil verity K-75. The results revealed that combination of oil cakes (neem cake, mahua cake, groundnut cake, sunflower cake) along with carbosulfan (nematicide) was found very effective on both reducing nematode population and increasing root nodulation in lentil. It have also found in lowering down the disease of fusarium wilt and root knot complex on lentil verity K-75 with different parameters viz., root lengths (8.13, 8.50, 7.51, 6.67 cm), root weight (4.36, 4.52, 4.15, 3.21), shoot length (36.68, 37.45, 34.75, 29.37 cm), shoot weight (17.12, 14.72, 12.43, 10.52 gm), root knot index(0.95, 1.00, 0.85, 1.00), minimum no. of root gall per plant (15.10, 20.00, 46.20, 20.20), maximum no. of rhizobium nodules per plant (50.00, 52.05, 65.10, 42.05) and minimum nematode population( 30.26, 31.15, 30.15, 25.56 ). Out of four cakes combination with different bioagents the best results have been found in neem cake followed by mahua cake.
