Utilization of arbuscular mycorrhizal rizosphere Imperata cylindrica to increase the yield of corn in podzolic soil: study of arbuscular mycorrhizal diversity.

Bladygrass (Imperata cylindrica) are categorised as weeds whose range of proliferation is wide. Bladygrass are capable of adapting to any types of soil and inclement climate. Only a few researches identify mycorrhizal symbiosis with the bladygrass roots. This research is aimed to explore the infecting capability, population of spores, and diversity of arbuscular mycorrhiza in the vegetation of bladygrass in arid soil in Kendari, the Province of southeast Sulawesi, Indonesia. Research activity involved observation and laboratory analysis. The research results are expected to be applicable in developing the application for the utilisation of arbuscular mycorrhiza to grow plants. From research results, it was obtained that on vegetation of bladygrass was found in several genuses of arbuscular mycorrhiza, with the infecting capability ranging from 56.67 – 86.67%, the number of spores ranging from 359 to 401 per 100 g soil.. Arbuscular mycorrhizal were found to be dominated by the genus of Glomus and Acaulospora.
