Phenology
Phenology is the study and recording of recurring biological stages in relation to environmental conditions. For a mango grower, useful stages include flushing, shoot rest, panicle emergence, bloom, fruit set, and harvest. A local record can show why an apparently sensible pruning or irrigation schedule produced a different result in another season. Dates alone are less informative than dates paired with weather, tree condition, and observations of the actual developmental stage.
