| Summary: | Oil palm is the major source of vegetable oil in the world and
Indonesia and Malaysia are the main palm oil producing
countries. Its fresh fruit bunch (FFB) yield refers to the quantity of
fresh fruit bunches harvested from oil palm trees. There is limited
knowledge on the factors accounting for variation in FFB yield.
This study investigated relationships between weather factors
with FFB yield and its components using data obtained from
study site Pahang Malaysia. The database included weather
variables and yield records for 35 years, portraying a wide range
of yield and environmental conditions. We used average monthly
and annual values to detect temporal variations in yield
associated with weather based on average rainfall, maximum
temperature, minimum rainfall and number of rainy days per
month. It is found that water stress was the key factor accounting
for temporal variation in oil palm yield. Our analysis also
highlights the importance of frequent rainfall as a stress factor in
oil palm, with this study being the first to demonstrate the
negative relationship between yield and rainfall frequency.
Meteorological anomalies during the drought period did not
exhibit major impact on yield which indicated significance of appropriate irrigation strategy. These findings extend current
knowledge about sources of variation in oil palm yield, providing
useful information to describe oil palm production in context of
environment and improve oil palm production by mitigating
negative weather impacts on yield. Moreover, it can facilitate oil
palm modeling and timely forecasting |
