AN ASSESSMENT OF THE STATUS OF SMALL RICE THRESHERS IN NIGERIA
AbstractAn assessment of existing rice thresher designs and products available within Nigeria and neighbour- ing countries was carried out. The impetus for the study is the concern that low and poor quality of local rice in Nigeria may be due, in important measure, to lack of appropriate and affordable small threshers. On this basis, a reconnaissance work in Five Local Government Areas in Ogun State, Erin – Ijesha in Osun State, Igbimo in Ekiti State; Abakaliki in Ebonyi State, Makurdi in Benue State as well as Kura - Kano and Tundun Wada areas of Kano State was carried out. Based on the farmers’ evaluation and assessment of existing rice threshers available in Nigeria, the study recommended three prototype small threshers that are pedal and petrol engine driven. The pedal operated thresher was recommended for those with farm hectarage of less than 2. For threshing freshly harvested rice at very high moisture content, the IITA/WARDA small plot spike-tooth thresher which has a threshing capacity of about 100kg/h was found to be appropriate for the small – scale farmers provided some little modifications in the area of capacity and mobility were carried out while the multi-crop thresher of the Institute of Agricultural Research and Training (IAR&T) Ibadan with a capacity of about 250kg/h was recommended for those with farm hectarage of more than 5ha.
