Okra [Abelmoschus esculentus (L.) Moench.] is an important vegetable crop grown in tropical and subtropical regions of the world. The production of okra suffers from number of pest and pathogens including nematodes. Amongst nematodes, root-knot nematode, Meloidogyne incognita is most important and responsible to cause significant economic losses in worldwide due to favorable soil and environmental conditions. In present investigation neem, karanj and mustard oil-cakes have been tested for the management of root-knot nematode, M. incognita infecting okra on farmer’s field naturally infested with test nematode. These were applied @ 2, 4 and 6 q/ha maintaining chemical treated (carbofuran 2 kg a.i./ha) and untreated control for comparing the experimental results. The observations on number of galls/plant, egg masses/plant, eggs and larvae/egg mass, final nematode population/100 cc soil and yield were recorded. Results showed that neem cake @ 6 q/ha was proved to be most effective for the management of M. incognita on okra while karanj cake @ 6 q/ha was found best to enhanced crop yield (49.18-53.51 %) followed by neem cake @ 6 q/ha (40.98-45.61%) and karanj cake @ 4 q/ha (39.34-43.86 %) over untreated control. Higher yield was obtained with the application of karnaj cake @ 6 q/ha as compared to carbofuran @ 2 kg a.i./ha during both the years.
