In this study, a soil culture experiment was set up in barrels to investigate the effect of waterlogging duration at different growth stages on the growth, yield, and quality of cotton in the Huang-Huai Region of China during summer. The experiment was conducted at four growth stages of cotton (seedling, squaring, flowering, and boll opening), and the waterlogging duration at each stage was set...

No. Poster–73 IMPACT OF COTTON LEAF CURL DISEASE (CLCuD) ON YIELD AND QUALITY OF FIBRE IN Bt COTTON IN PUNJAB Daljeet Singh, J.S. Gill, R.K. Gumber and Ramandeep Singh Punjab Agricultural University, Regional Station, India Cotton is one of the most important cash crops in India. Cotton leaf curl disease (CLCuD) , caused by a single stranded circular Gemini virus consisting of DNA A and two sat...

(1997) reported that yield in an ers must attempt to control the quality of the crop while maximizing irrigated cotton field in Texas displayed spatial correlayield. The objective of this research was to...

There currently are no data on using reduced tillage for flax (Linum usitatissimum L.) production when double-cropped after cotton (Gossypium hirsutum L.) in the southeastern USA. This study evaluated how tillage and subsoiling influenced double-cropped flax and cotton productivity and quality under conditions in the southeastern USA. An irrigated study on a loamy sand soil (Eunola loamy sand) ...

Typical applications of mepiquat chloride (1,1dimethylpiperidinium chloride) to control excessive vegetative growth in cotton (Gossypium hirsutum L.) are broadcastsprayed by ground or air. Mepiquat chloride also can be applied through a wick mounted to implements or sprayers that apply the chemical to only the top three to four nodes of the plant. In 1998 and 1999, the wick delivery system was ...

Identificationofquantitative traitloci (QTLs) for agronomic and fiber traits in upland cotton (Gossypium hirsutum L.) and their allelic association with molecular markers would be useful in cotton breeding. We used the mixed model approach of Zhu and Weir (1998) to analyze for QTLs associated with 19 agronomic and fiber traits across 96 F 2-derived families from the cross of two cotton lines, M...

White specks are undyed spots on d yed fabric, and are commonly caused by nep s. Since quality of a finished garment is determi ned by, among other things, the number of imperfection s contained within the fabric, the inclusion of white specks is detrimental to fabric quality. The manual counti g of neps is not only a time-consuming process, but a lso inconsistent and prone to error because it ...

The lack of hirsutum L.) for modern high-speed textile operations. The primary breeding progress for fiber quality has led some (Felker, objective of this study was to determine the...

ducted with modern cotton cultivars (Touchton et al., 1984; Bauer et al., 1993; Daniel et al., 1999; Larson et Thrips, primarily Frankliniella spp., can damage cotton (Gossypal., 2001). Grass cover crop residues generally have a ium hirsutum L.) seedlings. The objectives of this study were to determine the effect of winter cover crops on thrips populations in high C/N ratio, which causes N immo...

This thesis examines the capability of current techniques in fiber classification such as UV-visible microspectrophotometry (MSP) (for dye in situ and/or extracted) to discriminate between fibers from sources known to be different. When these methods fail to adequately distinguish the fibers, novel alternative techniques, such as pulsed pumped laser-induced fluorescence spectroscopy (LIF) and l...
