of grade standards: Universal Upland Grade Standards and American Pima Grade Standards. USDA’s American Upland cotton standards are referred to as “Universal” standards because they have been adopted by a special governing body and are recognized and used internationally.

USDA has twenty-five official color grades for American Upland cotton. Classification of Upland Cotton A.

There are fifteen (15) physical grade standards representing the predominant range of color and seven (7) physical grade standards representing the official leaf grades for American Upland cotton.

ble by telecommunications and contains classification data for the current and past year's crop. Access to the classification data is limited to the cur- rent owner of the cotton.

III. Classification of Upland Cotton A. Instrument Determinations Measurements for the following quahty factors are performed by high- volume, precision instruments.

Classification procedures for American Pima cotton are similar, including the use of high volume instrument measurements. The most significant distinction is the difference in color charts. Different grade standards are used because American Pima cotton is naturally a deeper yellow than American Upland cotton.

Classification procedures for American Pima cotton are similar to those for American Upland cotton, including the use of HVI measurements. Quality and Reliability of Classification Data The reproducibility of cotton classing results from one USDA facility to another is the measure used to determine the reliability of the data produced.

The success of this separation for American Upland cotton prompted the representatives of the American Pima industry to request this change in the standards for American Pima. The USDA's ability to provide useful and cost-effective cotton classification, standardization, and market news services will be enhanced by this change.

There are 25 official color grades for American Upland cotton, plus five categories of below grade color, as shown in the tabulation below. USDA maintains physical standards for 15 of the color grades. The others are descriptive standards. Color Grades of Upland Cotton. Effective Light Yellow.

Visual methods are based on the Universal Standards for Grades of American Upland Cotton which are produced and provided by the United States Department of Agriculture (USDA).

These standards are presented in the form of 15 different grade boxes, each of which contain six samples (known as “biscuits”) that represent the acceptable colour and amount of leaf or trash for the box’s assigned. The most typical range of +b in upland cotton is from 6 to There are 25 official color grades for American upland cotton (plus five categories of below grade color) and, traditionally, cotton classers determined the color grade of cotton by comparing a sample to physical color standards.

HVI Trash. Mexico, Central America, South America (northern, eastern Brazil). Cultivated as the principal source of cotton fibre throughout most of the tropics.

Introduced in eastern Europe, Western Asia, Central Asia, Sri Lanka, Bangladesh, China, Indochina, tropical Africa, southern USA, Caribbean, South America (Brazil) WSSA list of weeds in North America. A three-digit color code is determined by locating the point at which the Rd and +b values intersect on the color chart for American Upland cotton.

The color of cotton fibers can be affected by rainfall, freezes, insects, fungi, and staining through contact with soil, grass, or cotton-plant leaf. The success of this separation for American Upland cotton prompted the representatives of the American Pima industry to request this change in the standards for American Pima.

The USDA's ability to provide useful and cost-effective cotton classification, standardization, and market news services would be enhanced by this proposed change.

Gossypium hirsutum, also known as upland cotton or Mexican cotton, is the most widely planted species of cotton in the world.

Globally, about 90% of all cotton production is of cultivars derived from this species. In the United States, the world's largest exporter of cotton, it constitutes approximately 95% of all cotton production.

It is native to Mexico, the West Indies, northern South. Cotton color is an important measurement in judging fiber’s spinning quality in the current cotton classing system. This chapter first briefly reviews the history and major factors of cotton color grading, and then discusses the instrumental methods, including HVI colorimeter and color imaging system, that has been developed for objective and reliable grading of cotton color.

CDB started functioning in and started growing American Upland Cotton (Gossypium hirsutum) on experimental basis. There are 2 (two) types of cotton are producing in Bangladesh named.Cotton production is an important economic factor in the United States as the country leads, worldwide, in cotton exportation.

The United States is ranked third in production, behind China and India. Almost all of the cotton fiber growth and production occurs in southern and western states, dominated by Texas, California, Arizona, Mississippi, Arkansas, and Louisiana.Upland cotton is produced in every cotton -growing state and accounts for the vast majority of cotton grown in the United States.
