Abstract

Oil palm is the highest oil production potential per area when compared with other oil crops. Moreover, it was tolerance to natural effects than cash crop. One time investment can be harvested for 20 years. In the extraction of palm oil can be extracted by bringing fruit or palm bunches to extract through various processes. Therefore, the size of oil palm fruit and the components of oil palm fruit were important data for information in breeding. Thus, the objective of this experiment was to evaluate the portion sizes of 10-year-old commercial oil palm fruit grown under acid sulfate soils. Oil palm fruits were collected. The samples of various varieties were used in the experiment of oil palm plantations at Department of Agronomy, Faculty of Agriculture, Kasetsart University, Saraburi Province. The experiment was conducted from December 2020 to December 2021. The results showed that Surat Thani 3 oil palm variety had the largest fruit size and Uti oil palm variety had the largest kernel size. Therefore, the experiment show that oil palm varieties were different fruit size. The planting under acid sulfate soils, Surat Thani 3 oil palm variety was highest fruit size while Uti oil palm variety was highest kernel size.
