| Abstract | The indirect factor that holds significant appeal for farmers and the oil palm industry in assessing the potential of Tenera oil palm plantations is the total economic product (TEP). This comprehensive study, conducted at the Hong Sila Agriculture and Industry Company Limited in Krabi, Thailand, evaluated the factors influencing the TEP from twenty-two Tenera oil palms. The factors considered in TEP were fresh fruit bunch (FFB) recorded for 11 years from 2011 to 2021 and bunch components evaluated for four years from 2017 to 2020 using a randomized complete block design with four replicates. The results revealed that the factors influencing TEP were oil yield (OY) and kernel yield (KY), with OY having a more direct impact than KY. The kernel to bunch (KTB) and oil to bunch (OTB) multiplied by FFB are equal to KY and OY, so these two factors were factor affections. The factors that directly influenced OY were FFB and OTB, with no significant correlation between FFB and OTB and a small indirect effect of FFB through OTB. The strong direct effect of character on KY was obtained from KTB, followed by FFB, with a higher total effect of KTB over FFB. The average TEP in 22 Tenera oil palms was 64.41 kg/palm/year, with T22 giving the highest TEP at 74.55 kg/palm/year, while T12 displayed the lowest TEP at 53.86 kg/palm/year. TEP is the one parameter known for Tenera's potential to get more profit from the factors of FFB, OTB, and KTB, which was the one purpose for plant breeding to calculate for the selection process. |
