EKSPLORASI SPASIAL CENDAWAN TANAH PADA SEKITAR RHIZOSFER TANAMAN JAMBU METE (Anacardium occidentale L.) DI KARANGASEM DAN BULELENG-BALI

Abstract

Research have been carried out to calculate total colony of fungi, determine fungi
species, and the rate spread of the fungi in rhizosphere a cashew plantations (Anacardium
occidentale L.) at Sukadana Karangasem and Sendang Buleleng for 4 months (October 2012
- January 2013). Samples were taken from two different areas in which five point were
sampled. Results data were analyzed qualitatively by identifying the species of fungi that is a
description. The quantitative data was taken to calculate total colony of fungi. The research
found 11 species of fungi taken from two different locations, namely: Aspergilus flavus, A.
niger, A. parasiticus, Botrytis cinera, Cladosporium sphaeospermum, Fusarium
sporotrichioides, P. brevicompactum, P. citrinum, P. chrysogenum, Rhizopus stolonifer, and
Synchephalastrum racemosum. Total fungal colony in Sukadana Karangasem was : 33.6 x
103 - 35 x 103 CFU /g, in Sendang Buleleng 22.6 x 103 – 37.6 x 103 CFU/g. Abundance of
fungi in Sukadana Karangasem is relatively uniform (0.85) and in Sendang Buleleng belong
to cluster (1,03).
