Four cassava varieties: Rayong 1, Rayong 60, Rayong 90 and Kasetsart 50 were planted in sandy loam at Rayong province. Yields and starches were determined from the Tuber with different harvesting periods (6, 8, 10, 12, 14 and 16 months). The 4 varieties had a little different yields. The yeilds were increased by increasing of cassava ages. The starch contents were varied on varieties and harvesting dates. Rayong 90 and Kasetsart 50 had higher starch content than Rayong 1 and Rayong 60. The tuber harvested in dry season had higher starch content than in rainy season. Although the viscosities of starch extracted from different varieties were not different but dry season harvested starch viscosity was higher than rainy season.
