Leaf Photosynthetic Performance of Durian (Durio zibethinus) Under Different Fertilizer Zones: Seasonal Physiological Dataset

This dataset contains seasonal measurements of leaf eco-physiological parameters of durian (Durio zibethinus) trees grown under three fertilizer management zones: Zone B, Zone C, and Zone D. Measurements were taken using a portable gas-exchange system and SPAD chlorophyll meter during four key periods of the year: February, May, August, and November.

The dataset captures variation in photosynthesis rate, stomatal conductance, intercellular CO₂ concentration, and chlorophyll content, allowing assessment of how fertilizer regime and zone-specific soil conditions influence plant physiological performance.

This physiology-only dataset supports research in crop physiology, fertilizer response, plant–environment interaction, and durian agronomy.
