Abstract

The highest yield of corn seed is obtained at the best uniformity of their placement distances and density in the field. So, in this study by changing the components of the parameters witch effect on grooved roller metering device designing, it could be able to present a new design of metering device in Solidworks software and built from PTFE material for row-crop corn planting. The laboratory evaluation was done on grease belt in eight level of distance between seeds (8, 9, 10, 11, 12, 13, 14 and 15 cm) which were resulted from number of grooves (three levels) and metering device rotational speeds (eight levels) in 3/5 Km.h-1 forward speed. The multiple index, quality of feed index, miss index, precision index and damaged seeds were considered to evaluate the performance of grooved roller metering device. . By using completely randomized design with three replications in SAS and SPSS software, the results were analyzed. With multiple linear regression, the optimum amount of distance between seeds (11cm) that arose in 105rpm rotational speed of metering devices with 5 grooves.
