Citation: N/A Interpretive Summary: Numerous cotton cultivars are available for use by the farmer; however, the magnitude of the availability of cultivars and the complex interactions with climate conditions and soil types make it very difficult for farmers to select optimum cultivars . This study compares over 30 cotton cultivars planted in two common soil types in the Mississippi Delta. Results clearly yindicate the more economically favorable choices for the farmer and also identifies non-market fiber quality factors that are important to the textile mill. These results provide the necessary information for farmers to select cultivars and for plant breeders to evaluate potential improvements in market value and non-market fiber qualities.
Technical Abstract: Cleaning, drying and ginning of cotton cultivars on conventional ginning equipment produces commercially useful information for comparative purposes. Evaluation of numerous cultivars grown near Stoneville, MS, on two soil types indicated substantial differences between the cultivars in terms of monetary returns to the farmer and fiber properties important to the textile industry. Gross monetary returns ranged from $227 to $590.94 per acre. Classers' color was generally Middling grade but leaf ranged from 1.3 to 3.3. The number of neps ranged from 190 to 396 per gram of lint. The number of seed coat fragments ranged from 34 to 120 per 3 grams of lint. The short fiber content by weight ranged from 4.9% to 12.5%. Unfortunately, the "best" characteristics were not all present in the cultivars that yielded the highest monetary return. These results indicate the potential for improving cotton fiber quality parameters.
