ABSTRACT
Various organic amendments such as neem cake, mustard cake, farm yard manure and poultry manure were evaluated against root-knot nematode (Meloidogyne incognita) in eggplant. Application of mustard cake as a soil amendment resulted in the lowest root gall index, although plant mortality was observed with higher doses of mustard cake. Organic amendments such as neem cake, farm yard manure and poultry manure had no practical significance in managing root-knot nematode in eggplant because they were unable to reduce root galling. Subsequent nethouse experiments confirmed that the lowest root gall index was recorded with the highest dose (1.25 t/ha) of mustard cake as an amendment. Even the lowest dose of mustard cake (0.50 t/ha) application resulted in a root gall index of about 4. Hence, mustard oil cake can be used in managing M. incognita in eggplant under nethouse conditions in Punjab.
