An analysis of an alternative marketing system for cotton involving delayed ginning through various storage techniques
… the effects of storage on the quality of the lint and/or seed. Varying opinions are held by authorities on the feasibility of storing seed cotton in the delta region of Missouri. The objectives of this inquiry were to determine (1) the effects of prolonged seed cotton storage on cotton grade …

Individual Experiments to Evaluate the Effects of Plant Population and Planting Date, Cultivar and Plant Growth Regulator Application, and Herbicide and Plant Growth Regulator Application on Cotton (Gossypium hirsutum L.) Growth and Development, Yield, and Fiber Quality
… (Gossypium hirsutum L.) growth and development, lint yield, and fiber quality are influenced by many management decisions. Three field experiments examining the interaction of plant population and planting date, and cultivar or herbicide and plant growth regulator application on these parameters …

Effect of irrigation technology and plant density on cotton growth, yield, yield components, and water use efficiency
… and early boll development stage. The cotton lint yield varied and was statistically significant (p<0.05) between the irrigation technologies and rainfed condition with the LEPA having the highest cotton lint yield (950.3 kg ha⁻¹). The low-density provided the optimum cotton lint yield. The …

Quantitative trait loci mapping for agronomic and fiber quality traits in Upland cotton (Gossypium hirsutum L.) using molecular markers
… 2 LOD, in both IM and CIM. These include two for lint weight per boll, two for seedcotton weight per plant, and one for lint percentage, which collectively, based on IM analysis, explained 32.5%, 28.6%, and 4.4% of the phenotypic variation, respectively. In total, seven and nine different QTL were …

Using Winter Annual Cover Crops in a Virginia No-till Cotton Production System
… cotton growing season in 1995 resulted in higher lint yield for cotton grown following the hairy vetch + rye treatment compared with cotton grown following the wheat treatment. High heat unit accumulation in October 1995 led to the over maturity of cotton fiber and high micronaire values for …

Factors Affecting Within-plant Variation of Cotton Fiber Quality and Yield
Cotton is sold by weight, but a bale’s lint price per pound is determined by its fiber quality profile. Cotton quality is defined by a set of standardized properties (length, strength, elongation, uniformity, color, trash, and micronaire) collected on every United States bale. Each cotton fiber is …
