A field experiment was conducted in root-knot nematode infested plot to evaluate the efficacy of acacia compost individually and in integration with bioagents viz., Pochonia chlamydosporia and Paecilomyces lilacinus. Acacia compost, poultry manure and carbofuran were also tested. All the treatments were significantly superior over untreated check. Acasia compost enhanced the growth parameters with drastic reduction in root-knot index. However, the treatment combinations of acasia compost with different bioagents performed well with highest growth shoot, root length, root weight, yield and lowest root-knot indices. Among the integrated treatments, P. lilacinus with acacia compost recorded maximum growth parameters and yield with least root-knot index. In contrast with other works of combination treatments of two bioagents, P. lilacinus + P. chlamydosporia with acacia compost registered high root-knot index and decreased growth parameters and yield among the other integrated treatments. Further, poultry manure and carbofuran were on par with all the parameters studied.
