Two trials were established on inland soil in Melaka and coastal soil in Selangor in 1996 to study the performance of oil palms planted using big hole planting technique. Results indicated that the initial growth and yield of palms planted in the big planting hole on inland soil were better than the conventional technique in the first three years of bearing. This technique had improved soil moisture status and nutrient retention in the urea around the planting point. On the other hand the trial results also revealed that the additional nutrient inputs did not improve the palm performance significantly. In the coastal soil trial, the results indicated that three was no positive response to the palm growth and yield. Thus, there is no advantage in adopting the big hole technique which apparently creates non-conducive condition for root development. In both trials, incorporation of EFB in the big planting hole did not improve the growth and yield. As significant palm performance was recorded during the early years of establishment on the inland environment, the big hole planting has been adopted by Golden Hope in many inland estates. The additional expenditure incurred for constructing the big hole of 1.2m x 1.2m x 0.9m which was about RM 2.50/hole or RM 370.00/ha at 148 stand per hectare is justifiable as this would bring about an additional revenue of 15 % or 3.5 mt/ha during the first 36 months of harvesting. However, this technique is not recommended for coastal estate, as it has not given the desired result.
