Description Triple S (Storage in Sand and Sprouting) has emerged as future technology to conserve sweetpotato planting material in areas with long dry season. There has been a growing interest to scale up Triple S technology to sweetpotato farmers that live in dry areas of Sub-Saharan Africa. Although, the varieties in different countries are different, no evidence on the storage roots of different sweetpotato varieties performance in Triple S. Therefore, this study was conducted to understand sprouting, survival and planting material multiplication performance of roots of eight sweetpotato varieties in Triple S. Small, medium and large size root from each variety is stored in the standard Triple S during December, 2017 to End of March, 2018. From each variety, 60 roots (twenty roots from each size) are stored in one container. The experiment evaluated two factors, variety with 8 levels and root size with three levels in randomized complete block design (RCBD). Roots of variety Naspot 12 was strongest but variety Halaba was weakest performer in Triple S with 95% and 16% of survival and sprouting respectively. Roots of Naspot 13 were the most non-sprouting character with 50% non sprouted from roots stored in Triple S. The proportion of drying is also different among varieties and sizes with small size roots of Variety Halaba dried most. Generally; there is performance difference between varieties and size of same variety in terms of sprouting and survival percentage in Triple S. The current result suggests that variety is important factor for the success of Triple S and storage in sand is promising to prolong shelf life and long term availability of fresh roots of none sprouting varieties such as Naspot 13.
