Online published on 27 November, 2018. Abstract Cluster bean (Cyamopsis tetragonoloba L.) is an important multipurpose cash crop mainly cultivated in north western parts of the country especially in Rajasthan. It has been severely affected by number of pests and pathogens including plant parasitic nematodes. Amongst nematodes, root-knot nematode (Meloidogyne incognita) is reported to cause significant losses on cluster bean. The present investigation was carried out to test the efficacy of jatropha (Jatropha curcas), castor (Ricinus communis) and neem (Azadirachta indica) cake powder at 1, 2 and 4 q/ha as organic amendment for the management of root-knot nematode, M. incognita on cluster bean. A standard chemical check (carbofuran at 2 kg/ha) and untreated check was also kept for comparison. Results revealed that maximum increase in plant growth characters and significant reduction in nematode population was obtained with the application of neem cake at 4 q/ha followed by castor cake at 4 q/ha and neem cake at 2 q/ha over untreated check.
