Oil palm has become one of the most important industrial crops for its use for various purposes, but in vitro regeneration has become a critical route for accelerating breeding programs because of its constraints on traditional propagation. But its low survival rate caused catastrophic losses for the industry during the hardening process. Therefore, we optimized the acclimatization phase for 90-day-old plantlets from mature zygotic embryos germinated in vitro in this research. Using eight soil less media and their combinations in a 1:1:1 ratio, viz., plantlets were acclimatized. HM1 (Vermiculite), HM2 (Cocopeat), HM3 (Perlite), HM4 (Vermiculite + Cocopeat + Soilrite), HM5 (Cocopeat + Perlite + Soilrite), HM6 (Cocopeat + Perlite + Soilrite), HM7 (Cocopeat + Vermiculite + Perlite) and HM8 (Cocopeat + Perlite + Soilrite) (Compost). In terms of plant morphological features such as shoot length, root length, number of leaves, leaf length and leaf width, plantlets grown in the HM4 showed better results after 60 days of growth in the soilless media among all the treatments attempted. But, except for root growth, no statistical significance was observed. However, the introduction of staggered shift to the transition environment significantly decreased the transplantation shock.
