Determination of optimum seed rate for the production of sesame (Sesamum indicum L.) in the lowlands of North Shewa, Ethiopia

Abstract

On-farm study was conducted in the lowland areas of Kewot district in the North Shewa Zone, Ethiopia on two sites during 2011 crop season to determine optimum seed rate of sesame. Four seed rates (2, 4, 6 and 8 kg ha . Since the statistical analysis revealed non-significant difference among treatment yields, comparison was made by using total costs that vary. Accordingly, 2-4 kg ha -1 seed rate found to be optimum for the production of sesame under rain-fed condition around Kewot district and similar areas.
