N2 - The present study was conducted to examine the effects of two irrigation methods with different application rates on cotton (ST 4595B3XF variety) growth, irrigation water productivity, and fiber yield in Arizona. Five treatments, namely gravity drip (GD) with 100%, 80%, and 60% of crop evapotranspiration (ETc) and flood (F) with 100% and 80% of ETc (GD 100%, GD 80%, GD 60%, F100%, and F80%, respectively), were arranged in a randomized complete block design (RCBD) with three replicates during 2023. Deficit irrigation (DI) reduced cotton height and canopy cover with both GD and F irrigations. Compared with the F system, the enhanced vegetative growth resulted in a notable increase in total irrigation requirements, particularly evident in the GD 100% (1337.50 mm) and GD 80% (1106.60 mm). The highest fiber yield values of 1621 kg ha−1 and 1465 kg ha−1 were recorded under an irrigation rate of 100% ETc for both GD and F irrigation. However, decreasing irrigation rates to 80% and 60% ETc negatively affected fiber yield under the two irrigation systems. Improvement of irrigation water productivity (WPI), accompanied by saving irrigation water and a high fiber yield, could be obtained by shifting irrigation from the GD 100% (I = 1337.50 mm, WPI = 0.121 kg m−3) and F100% rates (I = 1162.00 mm, WPI = 0.125 kg m−3) toward the GD 80% rate (I =1106.60 mm, WPI = 0.130 kg m−3). The lowest micronaire (MIC) values were recorded under F 80 % and F 100% (4.36 and 4.97, respectively). The 100% treatment of F and GD showed higher fiber strength (STR) (29.51 and 28.29 HVI g tex−1, respectively). However, the upper half mean length (UHML), uniformity index (UI), and short fiber content (SFC) values showed a downward trend under both GD and F treatments, reflecting their correlation with the total applied water. Elongation at failure (ELO) was consistent among irrigation treatments. This study provides significant guidance for adopting DI strategies in cotton under semi-arid conditions.
