Utilizing residues of pearl millet, clusterbean, cauliflower and a mixture of off-season weeds, four types of composts were prepared under partially anaerobic conditions. Efforts were made to inactivate viable propagules of a soil-borne pathogen Macrophomina phaseolina during decomposition of infected residues. Amendment of soil with these composts reduced dry root rot incidence and increased the seed yield of clusterbean. In general, compost amendments increased the population of antagonistic actinomycetes, lytic and Nitrbsomonas bacteria and decreased the population of M. phaseolina in soil.
