Oil palm yield depends on many component traits that are determined during about 4 years between inflorescence meristem initiation and harvest. Yield also presents large inter-month variability as well as variability among trees in the field. To simulate this complex system we developed a plant growth model using i) plant source-sink relationships as drivers of plant phenotypic plasticity and ii) stochastic rules relating inflorescence characteristics to plant nutritional status.
