Özet

This research was carried out in two separate periods (spring and autumn) in 2018 to reveal the lettuce
response of yield, some quality, and plant nutrient content under different water stress conditions. In the
study, the effects of different irrigation levels applied with traditional deficit irrigation (TI) and partial root-
zone drying (PRD) techniques on lettuce growing were investigated. Lettuce (

water stress applications were effective on the criteria examined in lettuce. The highest total and marketable
yield values were obtained from the TF application, the second-highest values from the TI-125 application,
and the lowest yield from the PRD-50 in the autumn period. In the spring season, the lowest yield was ob
