Growth and Yield of Over-year Oil Palm Seedling in Krabi Province, Thailand
Keywords:
Elaeis guineensis, FFB, hybrid, large field plot, over-year seedlingAbstract
Performance of normal and over-year oil palm seedlings, in terms of the growth traits and yield production, was evaluated using three replications of a split plot in a randomized complete block design. The main plot was comprised of two types of oil palm seedling (normal and over-year), while the subplot contained seven different oil palm hybrids. Growth characteristics was recorded every 6 months from 12 to 60 months after transplanting (MAT), while the yield data was recorded from 31 to 66 MAT. All of the vegetative growth traits showed no significant difference between normal and over-year seedlings. During the first two years of harvesting, there was no significant difference in the fresh fruit bunch (FFB) production between normal and over-year seedlings. However, in the third year of harvesting, normal seedlings showed a significantly higher FFB than over-year seedlings, with yields of 163 and 145 kg/palm, respectively. The bunch number showed no significant difference between the two types of oil palm seedling. The Thai oil palm cultivars (Deli × Yangambi-T and Deli × Tanzania-T hybrids) had the highest 3-year accumulated FFB yield at 326 and 330 kg/palm, respectively. These results suggest that the hybrid oil palm cultivars bred and developed by the Thai companies can produce a FFB yield as high as the imported cultivars
