A study was conducted to investigate the effect of water stress at different growth stages on processing pepper (cv. Kapija) yield, water use and quality characteristics at Büyük Menderes Plain in Turkey during 2001 and 2002. Soil moisture content in the plots was determined gravimetrically in the soil layers 0-30, 30-60 and 60-90 cm during the whole growing season. The amount of soil water in the 0.60 m top layer was used to initiate irrigation. All the treatments were irrigated at the same time as the T1 treatment, being watered at each growth period (flowering, fruit formation, yellow fruit formation, beginning of the red ripening and ripening) with the amount of irrigation water required to fill the 0-60 cm soil depth to field capacity. Other treatments were irrigated similarly except for omitting the irrigation application at a specific growth stage. The different irrigation treatments significantly affected the yield and quality parameters. The highest irrigation water was applied to the full irrigation (T1-100%) treatment. The highest pepper yield (3006 and 3255 kg/da in 2001 and 2002, respectively) was obtained from full irrigation (T1-100%) treatment. Irrigation water use efficiency and water use efficiency ranged from 3.81-6.66 to 3.15-5.12 kg/da-mm, respectively, for treatments during both years. The period most sensitive to water stress was the flowering stage. The yield response factor was found to be 1.14 for the total growing season.
