Exploration of the indigenous rhizosphere fungi as corncob waste decomposers and its potential as biological agent Fusarium graminearum and increase corn growth

Abstract Corncob waste can be used as compost; corncob compost that microbial decomposers have composted positively affects soil and plants. The objectives of this study are 1). It was obtaining the type fungi from corn rhizosphere acts a decomposer 2) knowing potential in suppressing F. graminearum , which causes stem rot on increasing plant growth. designs for two steps were: Randomized Block Designs with ten treatments four replication. first step is using isolates composting waste. second testing by different types to suppress caused . Parameters observed number conidia propagules corncobs compost. third was: Incubation period, disease incidence, severity, dead plants, result research indicated obtained 15 varied color, shape colony, growth rate. highest found decomposed RF4, while classified high Rf, RF6 All able
