The effect of different seed weight of oil palm variety Sup PSU 1 on seed germination and seedling growth at one to four months after transplanting was investigated. The experiment was designed in a completely randomized design that composed of three seed sizes including small seeds (1.66-4.85 g per seed), medium seeds (4.86-8.05 g per seed) and large seeds (8.06-14.26 g per seed) with an average weight of 3.78 6.00 and 9.74 g per seed, respectively. The results showed that seed germination and mean germination time was similar among seed sizes ranged from 61.50-63.00 % and 15.35-15.96 days, respectively. The large seeds gave higher seedling growth in terms of stem diameter, leaf width, seedling fresh weight, seedling dry weight and Dickson quality index at four months after transplanting than those of medium seeds and small seeds. However, the oil palm seed weight on viz. medium and small seeds also had potential for oil palm seedling production. However, appreciate fertilizer management should be further studied.
