Malaysian Palm Oil Board (MPOB)
As the oil palm industry stands poised to enter the 21stcentury, it is an appropriate time to take stock of the lessons learned in the first 100 years of the crop in Malaysia. The end of the century is not just time to look at Y2K compliance for the new century, but, more importantly, to […]
Kilang minyak sawit menghasilkan bahan sampingan iaitu tandan buah kosong (TBK) yang banyak dan kebiasaannya dibakar. Amalan pembakaran dilarang oleh Jabatan Alam Sekitar di bawah Akta Udara Bersih. Oleh itu, penggunaan bahan sampingan ini memerlukan kaedah yang baru. Penggunaan TBK sebagai sungkupan di ladang sawit merupakan salah satu cara yang sesuai dalam penggunaan semula tandan […]
The production of food, fibre, oleochemicals and pharmaceuticals/ nutraceuticals by the oil palm industry is carried out under the progressive agricultural practices to ensure a safe and viable environment that is basic to sustainable development. Going back to basics requires two perspectives to be considered. The first is to have a telescopic global view that […]
The importance of water use efficiency in crop productivity including oil palm is discussed. Effects of water stress in oil palm e.g. sex ratio and fresh fruit bunch yield are also emphasized. The importance of photosynthesis proses and its limitations are also included. This review also includes carbon partitioning, hormonal effects e.g. absicic acid (ABA) […]
This paper develops the concept of the Malaysian National Average Oil Palm and evaluates the physiological characteristics required to produce the mean fresh fruit bunch (FFB) and mesocarp oil yields recorded in Malaysia between 1996-2000. The results are contrasted with those for oil palm in years of peak yield and with palms growing on a […]
Previous oil palm simulation models such as OPSIM and SIMPALM have relied on direct measurements of vegetative biomass and biomass production as a basis for predicting total biomass production and bunch yield. To overcome the limitations imposed by the need for extensive on site measurements, methods of simulating vegetative biomass production (VBP) are needed. This […]
The trunk represents an important component of the vegetative dry matter of oil palm. This paper describes the approaches taken to model trunk growth as part of a comprehensive model of oil palm dry matter production and development, and the problems and limitations encountered. Several approaches are described including the independent simulation of trunk height […]
This paper reviews past and recent work on at- mospheric concentrations of carbon dioxide (CO2)in and above stands of oil palm.Although data is limited, atmospheric CO2 concentrations both within and above stands,determined for several plantings,showed large diurnal variations with CO2accumulating to high levels over-night.Over much of the day, higher concentrations than are generally recognized as […]
Although fruit bunch production by oil palm is often considered to be mostly dependent upon the ability of the plant to produce assimilates, the availability of an adequate sink is also of importance in optimizing yield. The model OPRODSIM initially simulated yield based on the assimilates remaining after the requirements of vegetative growth had been […]
The model OPRODSIM is a mechanistic simulation model of oil palm growth and yield, the output of which depends crucially on the values assigned to various physiological and morphological characters. In this article, the effects of manipulating these values are explored and related to what is known concerning the magnitude of their natural variation. The […]
