Abstract

Several pot experiments were conducted to study the effect of inoculants of beneficial microorganisms on rice growth and disease suppression. Trichoderma sp. And Bacillus sp. were isolated from soil and inoculated separately into soil as suspension, powder or soaking as application form to plants. Dual culture test showed that although the linear growth of microbes on single culture plates increased after inoculation, the linear growth of Trichoderma viride was more rapid than that of Rhizoctonia oryzae. Significant inhibition (59.5%) of R. oryzae occurred after eight days. According to pathogenicity test compared to the control, lowest disease severity (DS) and disease incidence (DI) in any treatments were observed 21 days after the initial application of T. viride and Bacillus megaterium. Treatments with both microorganisms also significantly affect positive growth parameters like grain and stem drymatter, panicles and harvest index comparing to control plants, but the same effects were achieved in the chemical fertilizers treatment with NPK. Application form of microorganism and fertilizer had no significant different effect on plant length. The treatments with these microorganisms can be considered as equally effective on rice growth as mineral fertilizer and as growth promoters.
