Assessment of Commercial Oil Palm Varies (Elaeis guineensis Jacq.) in Phatthalung Province

Abstract

     This research was studied at Tha Chiat Research Station, Faculty of Natural Resources, Prince of Songkla University, Phatthalung Province. The experiment was carried out from February 2018 - February 2019, studied in the commercial oil palm tenera 8 varieties, 8 years of age, including; UT PR S7 S2 GT CP PU1 and CR. The experimental method was Randomized complete block design (RCBD), Growth and number of bunches data were collected from 4 replications/ varieties, 3 plants/replications and collected every 3 months for 1 year. Average bunch weight, bunch components and oil yield data were collected from 3 bunches/replications/year. The analysis of variance of Physical and chemical properties of soil levels was found to be low, analysis of characteristic variance found that UT oil palm is best grown with rachis length, S2 oil palm is best grown with leaflet number and petiole width, CR oil palm is best grown with plant height. The characteristics of the fresh fruit bunch, yield component, bunch component and oil yield were found that the oil palm variety of PU1 had fresh fruit bunch, average bunch weight and oil yield was the highest out of all 8 varieties. It was found that the UT varieties had the highest of number of bunch. PR varieties had the highest of %wet mesocarp/fruit. S7 varieties had the highest of %fruit/bunch and %oil/bunch. CP varieties had the highest of %oil/ dry mesocarp. The genetic rate found that the characteristics that should be used as the criteria for selection were rachis length, leaflet number, petiole width, plant height, fresh fruit bunches, average bunch weight, %oil/dry mesocarp and oil yield. Because there is a moderate genetic rate. When these traits were used for selection, UT S2 and CR showed good growth, whereas those of PU1 and CP showed good yields.
