I know the best time for applying fertilizer for mature plants are after rainfall seasons means between 6 or 8 months. I want to know more specific time (the months ) for that in Malaysia
Thank you so very much

The oil palm needs a lot of mineral salts to form its leaves and fruit clusters and it needs more nitrogen at young stage.
Dear Mohamad Yadegari
Your need for supplementing oil palm will best be served by doing foliar analysis and comparing to optimized values for the stage of development.
For accurate foliar analysis you will need 20 leaflets to be dried and analyzed. Some people can judge this based on the leaf color and there are chlorophyll meters which can be useful.
The greatest use of Nitrogen is in peak stages of growth and care should be taken not to over amend with Nitrogen as the plant will be top heavy. Depending on the acidity of the soil you may want to change how you amend your plant for Nitrogen. With your foliar analysis you will also get insight on other critical elements which might not be optimized and it may suggest soil treatments for further plantings.
Your nutritional plan should always include the complete soil analysis and even water analysis if you irrigate and needs fluctuate depending on the changes of environmental conditions particularly rainfall which will cause leaching and denitrification.
