Conteúdo: | Decomposition of organic matter in soil is known to increase microbial activity. Available information on the influence of this decomposition process on soil microflora, particularly the pathogenic forms, has been reviewed by Huber and Watson (1970), Linderman (1970) and Patrick and Toussoun (1965). The effect of soil amendments-with decomposable organic matter-on Fusarium spp. has been studied by Baker and Nash (1965), Sing and Singh (1970) and others. Studies on rhizosphere populations of micro-organisms, including those of Fusarium spp., in relation to organic amendments are, however, limited. Katznelson (1946) had suggested that addition of organic matter to soil may exert an indirect rhizospehre effect by influencing the rate of plant growth. Soil amendmements that suppress root pathogens increase soil microflora but decrease rhizosphere flora (Katznelson, 1965). Beans planted 25 days after amendment of soil with dry or geen crop residues and sawdust showed increase of R/S ratio from 6.6 in untreated soil to 9.3 in the amended soil. The present study was undertaken to investigate the influence of amendments with oil-cakes and sawdust on vegatative growth and sporulation of soil-borne Fusarium spp. in the rhizosphere of pigeon pea [Cajanus cajan(L.) Millsp.]
