ABSTRACT
Field experiments were conducted during Kharif 2013-14 to know the efficacy of bio agents viz., Pseudomonas fluorescens, Trichoderma viride, Paecilomyces lilacinus and Pochonia chlamydosporia and organic amendments viz., poultry manure and neem cake and combination of P. fluorescens with carbofuran 3G @ 0.3 ai. and T. viride with carbofuran 3G @ 0.3 ai. and carbofuran 3G alone for management of rice root-knot nematode Meloidogyne graminicola. The results revealed that all the treatments were significantly superior over check with respect to growth parameters and nematode population. However, the treatment combination of Pseudomonas fluorescens @20g/m² + Carbofuran 3G recorded highest plant height (83.26 cm), root length (20.60 cm), maximum grain yield (44.1 q/ha) and least nematode population (132.67/200g soil) with reduction of 79.34% nematode population followed by T. viride @20g/m² + carbofuran with plant height (81.67cm), root length (18.50 cm), grain yield (43.6 q/ha) with least nematode population (198.00/200g soil) with reduction of 69.17% nematode population.
