Use of ambient conditions and sawdust in storage of sweetpotato (Ipomoea batatas L.) roots in Kenya.

 

Storage experiments in ambient conditions and in sawdust using 31 Kenyan sweet potato clones were conducted in order to identify the most robust local varieties under natural storage conditions and to take advantage of a natural tropical environment that resembles artificial conditions in sweet potato storage. Visual examination of edible portions in stored roots showed that varieties KEMB 7, KEMB 9, KEMB 10, KEMB 20, KEMB 24, KEMB 37, KSP 20 and KSP 119 were acceptable and did not rot after 5 weeks of storage in ambient air conditions. Storage in sawdust permitted the storage of roots for up to 14 weeks (100 days) for most varieties. Although stored-root edible portion quality and colour were acceptable or good, sprouting was noted for almost all varieties. Shrivelling for KSP-type sweet potato roots was lower than for KEMB-type. Moisture loss was apparently an important determinant in storability and acceptability of roots and should therefore be minimized. These simple storage methods would e

xtend the shelf life of the perishable sweet potato for marketing and postharvest processing, and also help to release land for alternative utilization after harvest.
