An evaluation on the individual and concomitant effect of Meloidogyne incognita and Fusarium oxysporum f.sp. ciceri on chickpea

Pathogenic level of Meloidogyne incognita was documented to be j2 / g soil indicated by the reproduction of the nematode. On the basis of wilt index on tested plant, 1 g of mycelium mat could be produce significantly high index value. The presence of root knot nematode irrespective of the presence of other organism showed reduction in shoot length to a significant manner. However, maximum reduction in shoot length was observed in nematode inoculated one week prior to fungus. Both the organisms suppressed the plant growth parameters in general and shoot length in particular. Maximum reduction in nematode population was found to be in nematode alone and nematode followed by fungus inoculation. The wilt index on chickpea after 75 days was reduced to be 3.5, 4.0 and 4.2 in F + N, F7 + N, N7 + F, respectively.
