Field establishment of all seedlings was satisfactory, except for younger seedlings aged 6 and 8-month old (A6 and A8 treatments) which resulted in high mortality due to transplanting shock and pest’s infestation. At the immature stage, the vegetative growth differed signiftcantly with the seedlings age. However, at the mature stage, the vegetative growth affected by different treatments became less apparent, especially between treatments A10 and A12. The result of soil and leaf analysis indicated that the soil and nutrients uptake were not the limiting factors for palm growth at the study site. There was no signiftcant difference in the mean cumulative FFB yield as well as its components in A10 and A12 treatments over eight years. Oil palm planted using 10-month-old seedlings gave comparable FFB yield with 12-month-old seedlings. Therefore, seedlings of 10-month-old are suitable to be used as the minimum age of seedlings recommended for field planting. Bunch quality parameters showed satisfactory levels in most treatments. There were no signiftcant differences in bunch quality parameters of Al0 and Al2 treatments. However, the effects of different seedlings ages planted over eight years showed that the 12-month-old seedlings gave better overall performance than other treatments.

Tumbesaran semua anak benih yang berlainan umur adalah memuaskan kecuali untuk anak benih muda, iaitu rawatan A6 dan A8 yang menunjukkan kematian yang tinggi disebabkan oleh tegasan semasa pemindahan ke ladang dan serangan perosak. Pada peringkat pramatang, parameter tumbesaran tampang berbeza dengan ketara yang meningkat sejajar dengan usia anak benih. Walau bagaimanapun, pada peringkat matang, perbezaan tumbesaran tampang antara rawatan telah menjadi kurang berbeza terutamanya antara rawatan A10 dan A12. Keputusan analisis tanah dan daun menunjukkan tanah dan nutrien bukanlah factor pembatas tumbesaran sawit di tapak kajian. Selama lapan tahun, tiada perbezaan signiftkan didapati dalam purata hasil dan komponennya antara rawatan A10 dan A12. Sawit yang ditanam menggunakan anak benih 10 bulan memberikan hasil yang setanding dengan penggunaan anak benih 12 bulan. Oleh itu, anak benih 10 bulan sesuai untuk dijadikan umur minimum anak benih yang disarankan untuk penanaman di ladang. Parameter kualiti tandan menunjukkan tahap memuaskan dalam kebanyakan rawatan. Tiada perbezaan ketara dalam parameter kualiti tandan antara rawatan A10 dan A12. Walau bagaimanapun, kajian umur penanaman anak benih yang berbeza selama lapan tahun menunjukkan prestasi keseluruhan anak benih berusia 12 bulan memberikan prestasi yang lebih baik berbanding rawatan lain.
