Yield and fiber quality properties of cotton (Gossypium hirsutum L.) under water stress and non-stress conditions

Abstract

The primary objective of this study was to determine the effect of water stress and non-stress conditions on cotton yield and fiber quality properties. A two-year field study was carried out at the Southeastern Anatolia Agricultural Research Institute (SAARI), in 2009 and 2010, with the aim of evaluating 12 cotton genotypes for yield and fiber quality properties under irrigated and water stress conditions. The experiment was laid out as a randomized split block design (RSBD) with four replications. Significant differences were observed among genotypes and water treatments for seed cotton yield, fiber yield, ginning percentage and all fiber quality properties except fiber uniformity. Yield differences among genotypes under water stress and non-stress conditions were higher during the first season. In both years, SER-18 and Stoneville 468 cotton genotypes produced higher yield under water stress conditions, while Stoneville 468 produced higher yield under well-irrigated conditions. The results during the two years indicated that seed cotton yield decreased (48.04%) and fiber yield decreased (49.41%), due to water stress. Ginning percentage and fiber quality properties were also negatively affected by water stress treatment. Fiber length, fiber strength, fiber fineness and fiber elongation were decreased, while fiber uniformity was not affected by water stress treatment.

Irrigation’s effect and applied selection on the fiber quality of Ethyl MethaneSulfonate (EMS) treated upland cotton (Gossypium hirsutum L.)

“…However, for the commercial checks this was not the case. Other studies also occasionally found better fiber quality in the lower irrigation rate than the high irrigation rate (Pettigrew 2004;Bradow and Davidonis 2010;Karademir et al 2011). One reason for the increase in fiber quality may be due to fewer bolls being produced and taking resources from the bolls already produced (Bradow and Davidonis 2010).…”

Cotton Cultivation in Greece under Sustainable Utilization of Inputs

“…Cotton fibers carry a wide variability of properties, and it was stated that corresponding fiber characteristics depend on many factors such as cultivation area and soil parameters, weather conditions, inputs, and methods of harvesting and ginning [43][44][45]. Average yields of cotton vary widely [46], although as global climate changes continue, water shortage and drought have become an increasingly serious constraint limiting crop production worldwide [47].…”

Effect of Irrigation Intervals and Defoliant Application on Yield and Fiber Quality of Giza 92 Cotton Variety

“…were obtained from the third irrigation treatment (I 3 ).In conclusion, cotton seed yield /plant decreased as the irrigation interval increased, which agrees with the results obtained by Silvertooth and Galadima (2003) ; Zaxos et al (2012) while , Jill et al . (2006); Cetin et al(2011). This may be due to the fact that cotton plants irrigated normally are characterized by strong vegetative growth,which results in a great accumulation of the plant dry matter, and enhanced productivity.…”

“…These results are in line with those obtained by Silvertooth &Galadima (2002), andZaxos et al (2012) while ( Jill et al (2006). , andCetin et al,2011) This may be due to the fact that cotton plants irrigated normally are characterized with strong vegetative growth. resulting in greater accumulation of dry matter, which enhances cotton fiber length.…”

“…Defoliation is useful when cotton plants face some stresses like drought and high temperature. Also, water stress especially during fruiting stage adversely affected yield and fiber quality (Silvertooth andGaladima 2003 andZaxos et al, 2012) while, ( Jill et al, 2006 andCetin et al,2011) indicated that variable rate irrigation affected fiber lint yield and quality. Fiber quality parameters of interest are micronaire value, fiber strength, and fiber length properties.…”
