Modeling oil palm bunch components, palm oil and kernel yields

The source-based model OPRODSIM (Oil Palm Production Simulator) simulates fresh fruit bunch (FFB) yield based on the assimilate remaining after the requirements of vegetative growth have been met. However, in its initial form it does not take account of pollination as a factor limiting yield, nor does it provide an estimate of palm mesocarp oil […]

Biodiversity, agricultural development and valuation of ecosystem services

There have been significant losses of biodiversity in the tropics at ecosystem, species and genetic levels as a consequence of agricultural development resulting in simplified landscapes with large areas dominated by crop monocultures. While it is suggested that many ecosystem services can be maintained by a few key species under present environmental conditions, particularly in […]

Pesticide application in the oil palm plantation

This article attempts to give an overview of the combined practice of pesticide management in oil palm plantations, the types of pesticides commonly used and the method of analysis to determine pesticide residues in palm oil. A brief outline of the regulatory controls for pesticides is also included. Artikel ini memberi suatu peninjauan umum tentang […]

Modelling oil palm yield based on source and sink

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 […]
