TAILIEUCHUNG - Quantifying the interaction between root-knot nematode (Meloidogyne incognita) and Rhizobium on Moong (Vigna radiata)

Interaction between Root-knot Nematode and Rhizobia was evaluated in the green house on moong variety (SML-668). Seeds of the moong variety were sown in sterilized potted sandy soil and inoculated with 1000 freshly hatched juveniles of root knot nematode and 2ml rhizobia per pot (purchased from market). Treatments were kept as T1 (Pot without nematode), T2 (with 1000 J2 inoculated/pot), T3 (with 2ml of rhizobia/pot), T4 (pot with 2ml of rhizobia +1000 nematode inoculated simultaneously), T5 (with 1000 j2 inoculated one week before rhizobia) and T6 (with 2ml of rhizobia inoculated one week before nematode) and these pots were maintained for one month. Results revealed that the number of nodules developing on root-knot-infected roots (nodules/seedling) was lower than on healthy roots. When we added nematode simultaneously with rhizobia, singly or in combination reduced the number of nodules on moongbean as compared to check plants whereas nodulation is more in plants treated with rhizobia culture. | Quantifying the interaction between root-knot nematode (Meloidogyne incognita) and Rhizobium on Moong (Vigna radiata)
