ABSTRACT
A Study of Effectivity Utilization of Arbuscular Mycorrhizal-Fungae Inocullum
in Different Media and Host Plant on Brachiaria humidicola Grass
Sukma, N. H., P. D. M. H. Karti, and Soedarmadi
Forage supply is one effort to increase livestock productivity. The importance
of supply forage must be followed by increasing the production and quality
intensively. However, the problem in forage plantation is high anorganic fertilizer.
The use of anorganik fertilizer is relatively expensive and cause negative effects on
the environment, but use of biofertilizer is safe for environment. One of the
alternative biofertilizer that can be used is arbuscular mycorrhizal fungae. Many
informations have reported the advantages of arbuscular mycorrhizal fungae
symbioses in green house scale, but its application in open field scale is rare and
must be examined. Therefore, the objective of this experiment is to obtain a potential
arbuscular mycorrhizal fungi inocullum which is useful for forage growths in open
field scale.
Arbuscular mycorhhizal fungae inocullum was applied in latosol soil and
Brachiaria humidicola as host plant. A completely randomized design was used,
with 7 treatments (sand-Pueraria javanica, sand-Centrosema pubescens, soilPueraria javanica, soil-Centrosema pubescens, zeolit-Pueraria javanica, zeolitCentrosema pubescens and control) and 3 replications. The data were analyzed by
analysis of variance (ANOVA), and differences among the treatments were
examined with Duncan Range Multiple Test.
It is concluded that the addition of mycorrhizal inocullum did not
significantly increase root infection, spore number, stolon length, and shoot dry
weight in period I and II, but soil-Centrosema pubescens treatment significantly
