Utilization of arbuscular mycorrhizal rhizosphere Imperata cylindrica to increase the yield of corn in podzolic soil: the indigenous inoculum effectiveness studies

Abstract

Bladygrass (Imperata cylindrica) is the host for arbuscular mycorrhizal. Widespread deployment of bladygrass make arbuscular mycorrhizal inoculum easy to find. In this research examined the effectiveness of a indigenous inoculums. The inoculum obtained from rhizosphere bladygrass in the field, which is a mixture of soil containing spores and hyphae, and root hair pieces bladygrass. This research was carried out with arbuscular mycorrhiza culturing in plastic pots, using corn and bladygrass as a host plant. Observation variable were the root infection and the number of spores. .The results showed the development of arbuscular mycorrhizal in corn plant cells and bladygrass is quite good. This is indicated by an increase in root infection and the number of spores, which is consistent with the increasing age of the plant up to the age of 60 days after the plants inoculated. Root infection increase on the plant age of 60 day after inoculated was 28.48% and 31.33%, on corn plant and bladygrass respectively, compared with the plant age of 30 days after inoculated. Similarly with the number of spores on plant age 60 days after inoculated, an increase of 317.91% and 280.72%, on corn plant and bladygrass respectively, compared with the plant age of 15 days after inoculated. This is an indication that the indigenous inoculum, which taken from bladygrass rhizosphere in field, it was effectively used as arbuscular mycorrhizal inoculum on corn plant.
