Ikram A., . Role of plant growth-promoting Rhizobacteria in influencing the early growth of Pueraria phaseoloides and Calopogonium caeruleum - inoculum dosage and survival in peat-based cultures Malaysia. pp. 40-47. ISSN 0127-7065
Abstract
The amount of inoculum needed for a successful plant growth-response to plant growth-promoting rhizobacteria (PGPR) inoculation was determined by inoculating Pueraria phaseoloides with five dosages of strains 7NSK2 TL3 BK1 and CR30 and Calopogonium caeruleum with 7NSK2 in two soils. Responses varied with crop PGPR strain and soil factors. Under glasshouse conditions strain TL3 caused statistically-significant yield increases of P. phaseloides in Segamat series soil at a minimum dosage level of 3.8 x 100000 cells/g soil whilst 7NSK2 BK1 and CR30 appeared ineffective at all dosage levels. Strain 7NSK2 caused statistically-significant yield responses from C. caeruleum at an inoculum dose of 5-6 x 100000000 cells/g soil in both Segamat and Beserah series soil. Sterilised milled peat when incorporated with single strains of TL3 7NSK2 and 34-13 proved a suitable carrier material for long-term survival of PGPR strains at high populations. The development of procedures for preserving PGPR inoculum in peat is described
