Abstract

The objectives of this study were to collect informations on the method of postharvest
handling of sorghum and to investigate the moisture contents, insects infestation, fungal
infection, and aflatoxin B contents of stored sorghum grains collected from various stages
of the delivery chain in Demak and Wonogiri regencies, Central Java. In Demak regency
sorghum cultivation was monoculture, variety cultivated was UPC-S1. In Wonogiri regency
sorghum cultivation was intercropping with secondary crop and cassava. Sorghum varieties
cultivated were Kawali, Numbu, ZH30, Mandau and Hibrida hybrids. There was a difference
between the method of postharvest handling of sorghum at farmer and collector levels in
Demak andWonogiri regencies. In general the method of postharvest handling of sorghum in
Demak regency was more appropriate and more advance compared to that in Wonogiri
regency. The moisture contents of sorghum at farmer as well as at collector level in Demak
regency (13.0%) and Wonogiri regency (12.9%) were still lower that that of normal (safe)
moisture content of sorghum. The number of insect species associated with sorghum in
various distribution level in Demak andWonogiri regencies was 10 and 17 species, respectively.
The dominant insects species were and . The number of
fungal species found in sorghum at various distribution level in Demak andWonogiri regencies
was 23 species, respectively. In general, the dominant fungal species were ,
and . In Demak regency aflatoxin B contents of sorghum at
farmer and collector levels were 22.50 and 15.45 ppb, respectively, while in Wonogiri regency
2.27 and 10.28 ppb, respectively.
