| dc.description | Water is a fundamental requirement for all crops and plays an important role in oil palm yield.The evapotranspiration of mature oil palm is generally assumed to be about 5 mm per day (30,000 lts per ha per day). The main objective of this paper is to investigate how water management using shakaerator can be applied to improve water storage and aeration and hence improve yields of oil palms under Malaysian conditions. Depending on soil type, terrain and amount of rainfall, surface runoff account for a significant amount of water loss from rain .Water management is therefore concentrated on the interception of surface runoff Three empirical studies have been done in three estates covering about 4000 ha in Negeri Sembilan (2) and Pahang (1). Shakaerator was done in two matured areas and one in replanting area. Preliminary results of 3 years in matured areas shows an average increase of 8.5% to 14.5 % increase in yields compared to adjoining fields or to previous three years yield before the area was shakaerated. Result also shows that both estates experience a change in monthly percentage yield from the normal 40% yearly yield for the first 6 months has changed to 55% to 60%. Initial results for replanting area shows an increase in leaf area index by an average of 33%. | |
