Abstract

Interactions between plant parasitic nematodes and beneficial and detrimental microorganisms are very important. In the present study, impact of interaction between root-knot nematode (Meloidogyne javanica) collected from naturally infected tomato plants in fields of Varamin and Rhizobium leguminosarum bv. phaseoli obtained from kidney bean plants in Ahar-East Azarbaijan on kidney-bean I CV.COS-16 was studied under greenhouse condition. The plants were raised in pots containing 1 kg sterile soil and depending on the treatment, each pot received 2000 J2 of M javanica and/or 2 ml bacterial suspension at concentration of 107 cells/ ml. The treatments were control (no nematode and no bacterium), nematode alone, bacterium alone, inoculation of bacterium 10 days before nematode and inoculation of nematode 10 days before bacterium and simultaneous inoculation of nematode and bacterium. Each treatment had eight replications and for all the experiments, completely randomized design was used. The data collected were subjected to analysis of variance (ANOVA) using SAS software and differences among the treatments were determined by Duncan's multiple range test. The results revealed that the treatment of bacterium alone increased dry root weight, level of nitrogen in roots and shoots over all other treatments. Nematode population (number of root -knots, females, egg masses, eggs, nematodes in soil and multiplication rate (Pf/Pi)) was highest in the treatment that received nematode alone as compared to other treatments. Dry root weight, level of nitrogen and number of bacterial nodules were reduced in treatments that inoculated with nematode alone, simultaneous inoculation of nematode and bacterium, bacterium 10 days after nematode and nematode 10 days after bacterium inoculation. In these treatments, presence of bacterium decreased nematode population over the treatment of nematode alone. These findings can be considered in ROOT KNOT NEMATODE management on kidney been.
