“…Similar to our results, Özbek (2011) determined a direct relationship between fiber brightness and harvest time, and reported that fiber brightness decreases due to rainfall and other environmental factors as the harvest time is delayed. Our results also in agreement with the findings of Dadgar (2020), who reported that the most important parameters determining the cotton quality, such as the yellowness density and fiber color are harvest time, harvest method and storage conditions. Our findings on cotton color change are consistent with the findings of Meredith (1986), who stated that 79% of the variation in fiber color change is caused by environmental factors.…”

Cotton fibers are the most important raw material of the textile industry. Clean collection of cotton fibers increases the quality of textile products and the market prices. This study was conducted to investigate the effects of normal and late harvest period of different cotton varieties on cotton fiber and yarn properties. The quality properties of the fibers were determined with the HVI device, and the quality properties of the yarns obtained from the fibers were determined with the USTER TESTER device. The fiber quality properties such as fiber fineness (micronaire), fiber maturity, fiber length (UHML, mm), strength (g/tex), brightness/whiteness (Rd), and yarn quality properties such as yarn evenness (%), thin places, neps+200 (%) and hairiness were investigated in the study. The exposure of fibers to rain during the harvest period of 2018 caused a decrease in the quality properties. Inability of the plants to receive sufficient sunlight during the last physiological development period caused a decrease in photosynthesis rate. This negative situation negatively affected the physical quality properties of fiber and yarn. The results indicated that the physical quality properties of fibers and yarns obtained in 2019 were higher than those in 2018. The aim of this study was to determine the effect of late harvest period on fiber and yarn quality properties and thus on quality of textile products. In addition, the study was carried out to guide researchers who will conduct researchers on similar topics.

“…The fiber quality, as well as yield, is determined by a complex interaction among genotypes, environmental fluctuations during plant growth and development, and the genetic response controlled by genotypes to those environmental conditions (Oosterhuis, 1990). Nevertheless, the quality properties of the fiber entering the industry can also be affected by other postmaturity factors such as harvest and ginning methods, and harvest time (HT) (Bednarz et al, 2002;Bradow & Davidonis, 2010;Cevheri & Şahin, 2021;Dadgar, 2020;Siddiqui et al, 2020). The term "weathering" could be defined as the reduction or modification of yield and quality parameters of crops as the result of different environmental conditions from the time of physiological maturation to harvest.…”

“…The environmental factors that could most affect fiber quality after boll opening are rain, relative humidity, wind, frost, hail, and UV radiation, as well as the occurrence of insects, fungi, bacteria, and fiber stained with plant debris (Bednarz et al., 2002; Kelly, 2006). These factors can negatively affect different fiber quality parameters such as strength, color, and trash content, thus reducing the market value of cotton (Bradow & Davidonis, 2010; Dadgar, 2020; Duckett et al., 1999; Hake et al., 1992).…”

Delayed harvest time affects strength and color parameters in cotton fibers

Cotton (Gossypium hirsutum L.) is the most widely used natural fiber worldwide in the textile industry; thus, maintaining or even improving fiber quality is essential to produce the best quality yarn and uniform fabrics. Final fiber quality properties are determined not only by genotypes or environmental conditions during crop development but can also be affected by other postmaturity factors, such as harvesting and ginning methods, and harvest time (HT). The aim of this study is to associate the different environmental factors that affect specific lint quality traits produced by a delay in HT, also assessing cultivar effect. This field study included four cotton cultivars evaluated at seven different HTs (manual harvested) for different quality parameters. Results indicate that prolonged exposure of cotton fiber to the environment affects lint percentage (LP), strength (Str), reflectance (Rd), and yellowness (+b). Str showed a decrease of 0.02 g tex −1 day −1 from defoliant application, whereas LP, Rd, and +b presented different rates according to the season. No differences were obtained neither for length nor for fineness and maturity (micronaire) traits. In addition, the analysis of the results together with the climatic data recorded during the experiments indicated a negative correlation among Str, Rd, and +b with the number of rainy days, accumulated precipitation, and frost temperatures. Overall, this study establishes specific relationships between certain fiber characteristics and environmental conditions, being an important tool for crop management with regards to climate predictions that could help to make estimates of economic losses when the harvest is delayed.
