Abstract

Threshing performance evaluation was carried out using thresh efficiency, grain clean rate and grain breakage at the Ghana Irrigation Development Rice Field (GIDA) Tema - Ghana. It was aimed at the comparative evaluation of Japanese rice thresher ‘Kubota MD300’ and locally built rice thresher in Ghana. The performance indices included threshing intensity, capacity utilization, power requirement, threshing efficiency, cleaning efficiency, grain recovery range, percent total losses, number of adjustments and portability. Using standard methods, general and empirical measures were conducted to compare the performance of the two threshers. Generally, the KUBOTA MD 300 performed relatively more efficient as evaluated against the locally manufactured thresher (GIDA).  The KUBOTA (MD 300) had higher performance than the GIDA rice thresher in almost all the performance indices measured and for that matter the GIDA rice thresher needs to be improved to reduce if not eliminate most of the losses that accompany its usage. The data provided fills a serious gap in threshing knowledge and meet a need for efficient threshing and provides information on machine performance and its effects on rice to ensure quality rice threshing in Ghana. The government, non-governmental organizations and other stakeholders in the rice production sector should try and help in reducing if not absorbing the cost of importation of these Japanese Rice threshers into the country to make them affordable.
