shPostharvest quality of groundnut results from the particular set of environmental and cultural practices that influence physiology and maturation. Groundnut composition, although related to environment, changes dramatically as groundnuts mature. A biochemical basis exists for inferior quality in immature groundnut. Drought stress and soil temperature influence maturaton rate and thus have an indirect effect on postharvest quality. Aspergillus flavus invasion and alfatoxin contamination in groundnuts are related to drought stress, soil temperature, and maturity. Small, immature seed are more likely to be contaminated with A. flavus than larger, mature seed. The biochemical composition, fungal contamination, and the tendency toward higher moisture content complicate storage of immature seed. Each of these factors predisposes immature seed to rapid quality deterioration in storage. Agrometeorological studies must include an awareness of the relationships between environment, maturity, and postharvest qua
