Effects of cutting storage duration and methods on germination, growth and yield of cassava was studied at the Center for Research and Development of Cassava, Huay Bong subdistrict, Dan Khun Thod district, Nakhon Ratchasima province during March 2003-February 2004. A 3*2*5 Factorial in RCBD was used and replication 4 times. Treatments were 3 cultivars of cassava (MKUC 34-114-106, Huay Bong 60 and Kasetsart 50), 2 cutting storage methods (field storage with base earthened up and shade storage) and 5 storage duration (0, 15, 30, 45 and 60 days after cutting). The results illustrated that among cultivars, significant differences were observed in the following characters, percent stem moisture, percent germination, percent survival, dry root yield and starch content (percent). MKUC 34-114-106 had the greatest percent germination, percent survival, root dry matter yield and starch content (percent) (96.7 percent, 95.4 percent, 2,185 kg/rai and 28.2 percent, respectively). Cutting storage methods significantly affected percent stem moisture and percent stem length (only vital, usable part). Field storage resulted in greater percent stem moisture (66.1 percent vs 62.8 percent) and stem length (70.8 vs 67.0 percent) than shade storage. For cutting storage duration, the result indicated that longer storage duration reduced percent stem moisture, percent stem length (only vital, usable part), percent germination and percent survival whereas fresh root yield and dry root yield tended to decrease. However, the root starch content remained constant.
