Abstract:
The smallholder rice farmers h: ihe Uganda dry their paddy using open-sun drying method. In
most cases the paddy is badly
:;nd has very high fissure levels. Such paddy on milling
contributes to low levels of mi?: recovery and wliok grain ?:rice. This study was
therefore done to find a recoamM Uo
depf?;, % < ? (? drying of the prc-doniinant
local Kaiso rice variety in eastev::
t. ki eachihc paddy was open-sun dried on
cemented floor at ten different uvpf as: eontroL 30 mm, 49 nw?50 mm, 60 nmi. 70 mm, 80 mm, 90
mm, 100 mm and 110 mm. Drying dine showed a linear reiationssnp with paddy drying depth. Mill
recovery increased from 57.4 % at control to a maximum average vahie of 66.3 % and thereafter
declined progressively to 63.5 % at 11 Omni depth. 2 ?:n?a>Jniinn increment of 14.1 % in whole
grain level over control occurred at 70mm depth. FiiuH,;:???“m this work indicate that the best
drying depths for Kaiso rice variety using open sun drying r /¦< -
However at these depths,
the paddy takes 7-8 days to dry. It is therefore recommended ihai more research should be done
to reduce the drying time to a manageable level.
