Experiments were conducted at Sriracha Research Station in Chon Buri during 1988-1990. Two experiments were planted in dry season (November and February), another experiment was planted in rainy season (June). Three cassava varieties were used namely; Rayong 1, Rayong 60 and Sriracha 1. The treatments consisted of varieties and harvesting times at 8, 10, 12 and 14 months after planting. A 3*4 factorial experiment in RCB with 4 replications was used. There was no significant differences in fresh root yield comparing among varieties, except in February planting. Rayong 60 tended to have the highest fresh root yield while Sriracha 1 gave higher the starch content and dry root yield. During rainy season, increased the harvesting times of cassava from 8 to 14 months would increased the yield. Interactions between varieties and harvesting times of fresh and dry root yield were not detected, except for the starch content. Furthermore, planting in November gave higher yield than planting in February and June.
