Elaeis guineensisJacq. (oil palm) production is threatened by drought due to climate change and anthropogenic deforestation. This study aims to understand how drought conditions contribute to changes in foliar nitrate-nitrogen concentration as well as the effects on the growth and development of...

Riset Perkebunan Nusantara (RPN) has been carried out diverse research activities in plantation breeding for years. It has been a common understanding that the current biotechnology approach cannot be separated from plant breeding research. However, there has never been any review on research topic ...

Global climatic change poses a considerable risk to Malaysia's booming oil palm industry as the inflorescence initiation and differentiation in oil palms are affected by drought stress. As a result, the proportion of female flowers significantly decreases, leading to reduced fruit bunch...

The carbon dioxide (CO₂) enrichment study on oil palm clone P164 using open top chamber (OTC) technique was conducted to evaluate the effects on oil palm growth, physiology, bunch production and oil quality. The palms were grown in OTC with two CO2 concentrations; 600 ppm (CO₂-enriched) and ambient ...

This study measured sap flow (SF) using Heat Ratio Method (HRM) to estimate the transpiration of two 14 years old oil palms for 29 days. Plant water potential (Ψ_frond) was also observed with a psychrometer. Environmental factors such as solar radiation (Qs), vapour pressure deficit (VPD), rainfall...

Cultivation of A. intrusa as cover crops in oil palm plantation plays a role in reducing water deficit as much as 90% on condition of higher water deficit occurred. The present study aimed to examine the roles of A. intrusa as land cover crop on water balance in oil palm plantation in Bireuen...

Oil palm is one of drought sensitive crops. Therefore, drought tolerance and water-use efficient oil palm planting material are needed to produce optimally in a climate-changing condition. One of the methods to see plant responses to drought in the nursery stage is using the Fraction to...

Soil water content is an important property to indicate the quality of peat in supporting plant growth. Soil nutrient is affected by water content, and each plant has varied adaptation to encounter water stress. This study aimed to observe the effect of water stress to leaf nutrients, nutrient...

Objective: The drought observed in sub-Saharan Africa is responsible for increasingly irregular rainfall from year to year, which makes it difficult to select and recommend efficient oil palm genotypes. This study aims to assess and classify oil palm genotypes according to their degrees of...
