摘要：Pot experiment was conducted during July-September 2006 to evaluate some organic amendments such as sesame ( Sesamum indicum ) biomass, buckwheat ( Fagopyrum esculentum ) biomass, neem ( Azadirachta indica ) leaves, chinaberry ( Melia azedarch ) leaves and chicken manure @ 1, 2 and 3 t ha -1 each against the rice root-knot nematode ( Meloidogyne graminicola Golden & Birchfield) in direct seeded rice. The treatments were replicated five times in a randomized complete block design. The number of second stage juveniles (J2) of M. graminicola was significantly low in chicken manure @ 3 t ha -1 . The root knot severity index was significantly low in sesame @ 3 t ha -1 , chinaberry @ 3, 2 or 1 t ha -1 , neem @ 3 t ha -1 and chicken manure @ 2 or 3 t ha -1 amended soil but root lesion severity index was lower only in chicken manure @ 2 t ha -1 treated plots. The fresh shoot weight and length were significantly high in chicken manure amendment @ 2 or 3 t ha -1 at 45th day after seeding. However, the fresh root weight, length, number of leaves and number of J2 recovered from the roots were non-significant.
