Two years study was conducted at Rayong and Cholburi, Land Development Centers in the East of Thailand, in Mabbon and Lang Suan soil series, respectively. The influence of soil moisture on growth and nutrient uptake of cassava (Manihot esculenta Crantz.) was investigated. Rainfall in this area was very slight from December to April and relatively excessive from July to October. Soil moisture content was determined with a neutron soil moisture meter at 30 cm. increment to the depth of 180 cm. The difference in water retention of these two soils contributed effectively to soil moisture status throughout the profile. Moisture content of Lang Suan soil was retained within the available water capacity range throughout the growing season. Meanwhile moisture of Mabbon soil to the depth of 30 cm. was about five months below the permanent wilting point. There was high significance in plant growth and yield of cassava between two locations. Cassava production from Mabbon soil which subjected to a period of very low soil moisture content was about one half of that from Lang Suan soil.
