| Abstract |
The aim of this investigation is to develop and evaluate a metering device for drilling wheat grains in hills. The developed metering device is a single sided flanged-disc with 4 cells. Three cell-sizes with 3 – 4, 5 – 6 and 7 -8 grain/cell, four forward speeds of 2, 4, 6 and 8 km/h were investigated. The main results in this study can be summarized in the following points: The maximum seeding rate of 72.52 kg/fed was obtained at ground-wheel speed of 20 rpm or metering-device speed of 83.3 rpm and cell size of 7 -8 grain/cell. Meanwhile, the minimum seeding rate of 34.39 kg/fed was obtained at ground-wheel speed of 60 rpm or metering-device speed of 333.3 rpm and cell size of 3 – 4 grain/cell. For designed metering device, the maximum wheat-grains germination of 100 % was obtained at ground-wheel speed of 20 rpm or metering-device speed of 83.3 rpm and cell size of 7 -8 grain/cell. Meanwhile, the minimum wheat-grains germination of 98.7 % was obtained at metering-device speed of 60 rpm and cell size of 3 – 4 grain/cell. For designed metering device, the maximum wheat-plant emergence of 96.6 % was obtained at forward speed of 2 km/h and cell size of 7 -8 grain/cell.
