Produksi dan Kandungan Mineral Pueraria phaseoloides dengan Tingkat Naungan dan Inokulasi Mikoriza Berbeda
Abstract: Problems of forage
management in the integration of livestock into oil palm and rubber plantations
in Indonesia are declining of light as the canopy of the plant increases and
acid soils containing low available P, Cu, and Zn. The objective of experiment
was to study the effect of shading and arbuscular mycorrhizal fungi (AMF)
inoculations on the production and content of P, Cu, and Zn of Pueraria
phaseoloides (Roxb.) Benth (puero). The experiment was arranged according to
the split plot design with three replicates in a green house. Treatments tested
were shading as the main plot (0%, 25%, 50%, and 75%) and AMF inoculations as
sub plots (indigenous AMF, Glomus manihotis, indigenous AMF + G. manihotis and
no inoculation). Root biomass was affected by shading level while leaf stem
ratio was affected by both shading level and AMF inoculations. Inoculations
with G. manihotis and indigenous + G. manihotis indicated higher herbage
production and P contents than inoculations with indigenous AMF. Effectiveness
of AMF inoculation on improvement of production and P uptake varied according
to shading conditions. P. phaseoloides was tolerant to shading up to 50% and
its production and P content as responses on inoculation of AMF were affected
by soil conditions and shading intensity. Inoculation of G. manihotis and its
combination with indigenous AMF improved production and P content of Pueraria
phaseoloides in shading level upto 50%.
