Abstract
This study assessed the extent to which rice producers from Kidwebeziirrigation scheme
could know their productivity loss during post-harvest activities and assessed the
performance of drying and storing paddy in Grain Safe Dryer. To achieve these objectives,
first simple random sampling was used to select 147 rice farmers in the study area. The
collected data were subjected to analysis where output responsiveness with respect to each
of the inputs, technical, allocation and economic efficiencies was estimated. Statistical
Package for Social Sciences (SPSS) analysis was used to estimate the perception of paddy
loss during post-harvest activities. The study further assessed factors affecting loss levels
among rice producers. Grain Safe Dryers were installed to assess the performance during
drying and storage of paddy. The study applied GENSTAT to analyse the data from using
Grain Safe Dryer to dry and store paddy. Findings of this study reveal that the paddy lost
during post-harvest activities were between 0 and 9%.Furthermore, the results show that
the major factor affecting post-harvest losses in the study area was the material used in
post-harvest activities. The study showed that the Grain Safe Dryer had high drying
performance comparing to the sun dried paddy. Moisture contents of dried paddy were
varied in sun drying and in the two Grain Safe Dryer units with the changes in atmospheric
conditions. The initial moisture content was 25.3%, which decreased until it all reached
11.7% (in 19 days) in Grain Safe Dryers and 13.9% (in 3days) under sun drying. In case of
germination percentage it was found to be higher (85.2%) in Grain Safe Dryer compared to
sun drying (80.8%). Quality of rice after milling was found to be better (80%) in Grain
Safe Dryer than sun drying (30%).On the other hand, seeds handled in Grain Safe Dryers
gave higher germination rate and quality due to moisture content removed slowly during
drying compared to sun drying. However, in terms of moisture removed, good quality, and
germination percentage in Grain Safe Dryers were better compared to the sun dried paddy.
However, it is recommended to carry more studies on Grain Safe Dryer to be assessed in
different ecological zones before wider dissemination of the hermetic storage system for
use as a dryer.
