Design, development and evaluation of a kenaf seed metering system based on its physical and aerodynamic properties

Mohammad Reza Bakhtiari

Abstract


In this study a vacuum seed metering system was designed and developed based on physical and aerodynamic properties of kenaf seed (Hibiscus cannabinus L.). The kenaf vacuum seed metering system was evaluated in the laboratory using kenaf seeds. For laboratory tests, a completely randomized design (CRD) with three replications was chosen. The data were analyzed by SAS program version 9.1 and means separation test were done using Duncan’s multiple range test (DMRT). Based on this study, the most suitable opening diameter and opening angle for planting kenaf seed are 2.5 mm and 120o respectively with having the minimum miss and multiple indices with having optimum quality of feed index.
