Abstract: Mortar and pestle has long being in used to de-pulp coffee cherries for planting either in small or in large scale farm. This method is very laborious, time consuming and is not devoid of seed damage. Therefore it becomes imperative to use mechanical pulper for both small and large scale seed production. Ripe coffee cherries were harvested during 2019 season from three different genotypes of Robusta coffee planted on the field. Two genotypes were selected from coffee germplasm and the third genotype was from agronomy plot all from cocoa research institute of Nigeria. The cherries were processed using both traditional method of de-pulping and manual drum pulper. Three operators were used to create different speed rate of 40, 75 and 90 rev/min. Equal quantity of cherries were fed into the pulper. The de-pulped coffee seeds were air dried, undamaged seed were selected for planting at pre-nursery. Data on seed emergence were collected periodically, twenty five days after sawing, forty days after sawing and sixty days after sawing. Data were subjected to analysis of variance (ANOVA) using statistical analysis system (SAS) version 9.1. The result shows best percentage de-pulping efficiency (99.91), separation efficiency (98.87) and percentage beans damage (0.2) were achieved with the machine speed range between 40-75 rev/min. The percentage seed emergence of genotype T797 (66.67), FM (66.67) and T45 (64.44) were statistical similar irrespective of de-pulping method used. Better machine performance was observed on genotype T797. Genotype FM de-pulped with manual drum pulper gave least germination percentage; lowest machine performance was observed on genotype FM. Coffee seed production with minimal affection on seed emergence, could be achieved through use of manual drum pulper to reduce time and labour required using traditional de-pulping method.
