| dc.description | This work focuses on production of indigenous beneficial microorganisms (IBM) isolated from virgin soil and its roles in enhancing the growth and productivity of crops. Several pot experiments were conducted to study the effect of inoculants of IBM on rice growth and disease suppression. Data from the dual culture test showed that the isolated Trichoderma viride and Bacillus megaterium on single culture plate suppressed growth of Rhizoctonia oryzae. For green house test, T. viride and B. megaterium enhance rice growth. Inoculation of rice seedlings with B. megaterium & T. viride produced maximum shoots and roots dry matter, increased root length numbers and seedlings height compared to control. A five factors Box–Behnken experimental design; concentrations of Carbon, Nitrogen source, Temperature, pH and rpm on the concentration of biomass in batch cultures of T. viride and a four factors design for B. Megaterium; initial pH, inoculums size, temperature and moisture content were employed. Optimal medium for maximizing the production of biomass of T.viride comprises of 45 g/l C, 0.35 g/l N, 30°C temp, 175 rpm and pH 6 for five days fermentation. The following conditions; pH 7,inoculum size of 1x1010 , temperature 24o C and 120 % moisture content were for maximizing the production of B. megaterium biomass. For production of biomass of T. viride and B. Megaterium using oil palm empty fruit bunches EFB, it was concluded that a change in inoculums size gave the maximum production of biomass concentration. The number of microbial inoculant cells (Bacillus & Trichoderma) in carrier EFB increased during the first 30 days when kept at 30o C. The Shelf-Life of T. viride & B. megaterium using EFB as carrier showed that T. viride gave the highest colony forming unit (cfu) in 4o C up to 210 days after inoculation. The maximum value of 3.8 X 108 cfu/g was calculated after 15 days of incubation in both temperature, and 210 days after inoculation 4 X 104 and 1.8 X 105 cfu/g, were increased at 4o C and 30o C respectively. The shelf-life of T. viride declined gradually with increase in storage period while the survival of B. megaterium 4o C and 30o C was the same overall storage time and reach, 3.5 x 105 , 2.8 x 105 cfu/g under 4o C and 30o C respectively. The results obtained in the present study indicate soil contained specific IBM (T. viride & B. Megaterium) which have the potential to enhance growth parameters of rice and pepper and inhibit the disease causative microbe.,Certification of Masters/ Doctorial Thesis" is not available | - |
