Abstract

Inoculant production of arbuscular mycorrhizal fungi (AMF) has a vital role in sustaining of higher forage legume production. Currently, it is important to find the alternative materials that can be used as sources of phosphorus due to the need of lower cost, environmentaly friendly, and easily available. Bone meal and rock phosphate are some of the bio-inorganic sources that can be used as a phosphorus source for producing biomass of forage legume and AMF's inoculant production. A glasshouse experiment was conducted to determine the effectiveness of different type of bio-inorganic materials as a fertilizer to increase forage legume biomass and for specific AMF's inoculant production. The experiment was arranged in a factorial randomized block design with two factors, i.e. type of AMF's species (Glomus etunicatum NPI-126 and Acaulospora tuberculata INDO-2) and type of bio-inorganic materials (artifical fertilizer solution as a control, SP36, rock phosphate, and bone meal).  Results showed that G. etunicatum gave better result in terms of host gowth, root colonization and spore production compare to A. tuberculata. Bone meal was better a phosphorus source for AMF's inoculant production instead of artifical fertilizer or other bio-anorganic sources. In conclusion, milled bone meal has a good phosphorus source for AMF's (G. etunicatum) inoculant production

Abstract

Bone meal is a natural source of calcium and phosphorus required for plant growth, but phosphorus can cause problems if they occur in high concentrations particularly will inhibit growth of mycorrhizal fungi. The aim of this study was to find the best diameter size and dosage of bone meal for increasing growth of forage legume Pueraria phaseoloides and for producing arbuscular mycorrhizal fungi (AMF) Glomus etunicatum inoculant. A glass house experiment was laid out in a randomized block design consisted of 13 treatments (control and 12 combination of different diameter size and weight of bone meal) and replicated three times. Bone meal and artificial fertilizer resulted the same effect (P>0.05) on dry matter of P. phaseoloides. Application of 25–40 mg with <250 µm diameter significantly (P<0.05) increased dry matter production. Bone meal reduced significantly (P<0.05) root colonization but increased significantly number of spores compared to that of artificial fertilizer. Reducing bone meal diameter significantly increased root colonization and number of spores of AMF G. etunicatum.
