Abstract
ABSTRACT Iceberg lettuce was evaluated for yield, microbial population, and postharvest quality either following different irrigation termination (IT) schedules or before and after a rainfall event. Lettuce receiving late (4 d before harvest) IT showed increased weight and diameter, higher aerobic bacteria counts, and lower quality than plants subjected to early (16 d before harvest) IT. Middle (8 d before harvest) IT produced similar yields, and lower microbial population in lettuce than late IT. After rain, microbial population increased by 1.5 and 3.0 log colony‐forming units (CFU)/g in outer and head leaves respectively. The results revealed the importance of managing moisture conditions at harvest to enhance overall quality of lettuce.
