Recent developments in cotton (Gossypium hirsutum L.) production technology in the Delta include drill planting cotton in an ultra-narrow-row (UNR) production system. Ultra-narrow-row cotton is a low-input production system designed to maximize economic returns. The premise is that UNR cotton will be lower yielding, but the reduction in input costs will result in a larger profit margin. Researc...

The efficacy of rye (Secale cereale) and wheat (Triticum aestivum) winter cover crops and cotton stalk and root destruction (i.e., pulling them up) were evaluated in field tests during two growing seasons for Hoplolaimus columbus management in cotton. The effect of removing debris from the field following root destruction also was evaluated. Wheat and rye produced similar amounts of biomass, an...

Greige cotton is an intact plant fiber. The cuticle and primary cell wall near the outer surface of the cotton fiber contains pectin, peroxidases, superoxide dismutase (SOD), and trace metals, which are associated with hydrogen peroxide (H₂O₂) generation during cotton fiber development. Traditionally, the processing of cotton into gauze involves scouring and bleaching processes that remove the ...

The introduction of transgenic insect-resistant cotton into agricultural ecosystems has raised concerns regarding its ecological effects. Many studies have been conducted to compare the differences in characteristics between transgenic cotton and conventional counterparts. However, few studies have focused on the different responses of transgenic cotton to stress conditions, especially to the c...

The objective of this study was to determine the effect of Verticillium dahliae Kleb. on cotton yield and fiber technological properties, relationships among to disease and seed cotton yield, fiber yield and fiber technological properties and also determine susceptible and tolerant cotton varieties. The study was conducted in the Southeastern Anatolia Agricultural Research Institute’s exper...

Of the several mechanisms that can bring about efficient resource use, the most widelyapplicable one is intercropping systems that can make better use of resources. The aim of thisstudy was to evaluate resource capture and resource use efficiency in transgenic cotton-peanutintercropping system and in their respective sole crops with using 25-50% substitution ofrecommended dose of nitrogen (RDN)...

There is narrow selectivity in cotton with regards to soil-applied herbicides, meaning that rates needed for effective weed control can likewise cause cotton injury, especially when environmental conditions are less than optimal for cotton emergence and growth. The objective of this research was to determine the influence of seed size, vigor, and planting depth on cotton injury from soil-applie...

Many developing countries face the decision of whether to approve the testing and commercial use of insecticidal transgenic cotton and the task of developing adequate regulations for its use. In this review, we outline concepts and provide information to assist farmers, regulators and scientists in making decisions concerning this technology. We address seven critical topics: 1) molecular and b...

High temperatures during cotton flowering and early boll development can detrimentally affect cotton yield. Current commercial cultivars do not have pronounced tolerance to elevated temperatures, and improved methods of screening for thermo-tolerance are needed. The effect of heat stress on cotton has been measured with several different methods including membrane leakage, chlorophyll fluoresce...

Cutinase from Thermobifida fusca was used to esterify the hydroxyl groups of cellulose with the fatty acids from triolein. Cutinase and triolein were pre-adsorbed on cotton and the reaction proceeded in a dry state during 48 h at 35°C. The cutinase-catalyzed esterification of the surface of cotton fabric resulted in the linkage of the oleate groups to the glycoside units of cotton cellulose. Th...
