The fields were naturally infested with Meloidoyne incognita at 2–3 J2/g soil. Talc preparations of fungal bioagents i.e. Aspergillus niger 1% W.P. (3×107 cfu/g) and Paecilomyces lilacinus 1% W.P. (2×106 cfu/g) at 5 kg/ha each were applied by enriching FYM at 5 tons/ha alone and in combinations with neem oilseed cake at 1.5 ha. Combined application of both the bioagents at half dose along with neem oilseed cake was found to be most effective in increasing the yield of chick pea and suppressed nematode multiplication as compared to farmer's practices and also found to be better than carbofuran. Two fold increase in the yield of chick pea was recorded in reduced dose treatment with a significant reduction up to 71 and 83% in number of galls and number of egg masses, respectively. The number of M. incognita in 10 roots of chick pea was reduced up to 61%. Thus, application of FYM enriched with fungal bioagents, A. niger and P. lilacinus along with neem cake may be an ideal approach for management of root-knot disease of chick pea under field condition.
