Field experiment on management of Meloidogyne incognita in Carnation var. Dona under poly house conditions was conducted to assess the efficacy of plant growth promoting rhizobacteria, single and combined application of Pseudomonas fluorescens and Bacillus subtilis. All the treatments were significantly increased the yield parameters viz., number of flowers per plant and total number of flowers per meter2 and also observed the reduction of root knot nematode population. Fifty per cent increased yield was recorded in P. fluorescens (Pfbv 22) @ 10g/m2 and combined application of P. fluorescens (Pfbv 22) + B. subtilis (Bbv57) each @ 5 g/m2 treated bed respectively compared to untreated control. The single soil application of P. fluorescens (Pfbv 22) @ 10g/m2 and combined application of P. fluorescens (Pfbv 22) + B. subtilis (Bbv57) each @ 5 g/m2 recorded lowest root knot nematode population of 62.9 and 60.5 per cent respectively compared to untreated control. However, the reduction in galls index, number of egg masses and adult nematode population was higher in P. fluorescens (Pfbv 22) @ 10/m2 alone treated bed.
