Seed cotton with a moisture content above 12% should not be stored. Also, the internal temperature of newly built modules should be monitored for the first 5 to 7 days of cotton storage; modules that experience a 11 ºC rise or are above 49 ºC should be ginned immediately to avoid the possibility of major loss. In , lint yields from the first two harvests were ginned with a commercial grade cotton gin and a total lint yield was calculated based on the ratio of seed cotton yield to lint. Samples for nematode population assessment were collected prior to planting (Pi), mid-season (Pm), and following the final harvest (Pf) during both by: 7. Goals / Objectives New markets for cotton fibers are demanding a more uniform, high-quality product. This requires innovative new designs and methods in the harvesting and ginning process that will require: (1) developing handling and cleaning systems for cotton strippers that will improve the cleanliness and quality of seed cotton; (2) developing non-contact moisture . Moisture Content. Monitor seed cotton moisture content at harvest, especially when using field cleaners to avoid damaging fiber quality. Under high-moisture-content conditions, field cleaners can cause seed cotton to have a “rope-like” appearance that reduces the gin’s ability to efficiently clean the cotton.

The seed cotton harvested at >12% had more trash with a leaf grade of 3, compared to a leaf grade of 2 for the seed cotton harvested at the 12% level. There was no significant difference between the two moisture levels in terms of fiber length and strength, but fiber micronaire was higher for the higher moisture by: 2.

However, low moisture content of seed cotton can lead to fiber breakage and an overall reduction in fiber quality during harvesting and ginning. Ginners must control the moisture content of cotton carefully to facilitate cleaning and ginning while minimizing fiber damage.

From the field, seed cotton moves to nearby gins for separation of lint and seed. The cotton first goes through dryers to reduce moisture content and then through cleaning equipment to remove foreign matter. These operations facilitate processing and improve fiber quality.

However, seed cotton moisture takes hours or days to equilibrate, due to the influence of the seed.

The incidence of seed damage also increased as seed moisture decreased, which is in disagreement with earlier results (Watson andCited by: Quality Effects from the Addition of Moisture to Seed Cotton with Two Surfactants.

Plants under closer spacing of 60 x 60cm (S2) produced significantly more LAI, seed cotton yield, crop profitability, crop productivity and PFPN over wider plant spacing (90 x 60cm), respectively, whereas % higher lint index was recorded under wider spacing.
Since moisture of seed cotton may affect cotton lint properties in the ginning process, moisture content of the seed cotton and lint was determined by the conventional oven method at the USDA-ARS CGRU at Stoneville, MS (Shepherd, ).
Data Analysis An ANOVA was performed with SAS software using the PROC MIXED procedure (SAS Institute Inc. The means of lint moisture content at the lint slide for the five treatments ranged from % to %. The ginning procedures signifi- cantly affected the lint moisture content, the grade of the lint (which included trash level at that time), the nep count in the raw cotton and in the spun yarn, and the yarn strength.

Although increased levels of seed moisture caused a slight reduction in percent oil, there was negligible effect on oil quality index and percent oil as affected by seed cotton moisture content or other storage variables.

germination limits the optimum moisture level around the seed because water restricts soil aeration or oxygen movement. Poor aeration is of major concern on clay soils, especially when the seed is planted into mud.

As seed cotton moisture increased from 13 to 16 percent, there was a marked decrease in seed germination, and for seed cotton moisture contents above 16 percent, the seed would not germinate.
Although increased levels of seed moisture caused a slight reduction in percent oil, there was negligible effect on oil quality index and percent oil as affected by seed cotton.
In normal cotton in most conditions moisture content must be 5 % to 6 % moisture level at the gin stand apron .

The lint in seed cotton dries quickly but the seed dry slowly. So when gins dry cotton they mostly dry only the lint portion of the seed cotton. Also the lint portion is the most susceptible to damage when ginning at lower mc. Drying control systems which measure the lint portion of the seed cotton are preferable to.
The round modules had seed cotton with better moisture levels, lint with better color, and they were processed somewhat more rapidly by the gin than with the other module types. However, because the variety, growth conditions, and harvest conditions of the seed cotton was uncontrolled the differences observed were too small to be able to.
Bale classification data were obtained at one gin and small differences in color were related to the module type. The round modules produced seed cotton with better moisture levels, lint with better color, and they were processed somewhat more rapidly by the gin Cited by: 1.
The first is in the seed cotton just prior to ginning, and the second is in the lint cotton prior to the baling press.
In many regions of the world, high ambient temperatures and low relative humidity during the harvesting and ginning season can produce seed cotton with moisture content levels in the 3 percent to 4 percent range.

The experimental treatments will use less mature cotton and both more and fewer saw-type lint cleaners at the gin. Conclusions will be based on analysis of advanced fiber information. The round modules produced seed cotton with better moisture levels, lint with better color, and they were processed somewhat more rapidly by the gin than with the other module types.

The primary objective of this experiment was to determine if seed-cotton cleaners used prior to the extractor-feeder/gin stand change SCF levels in ginned lint. Several cottons were processed at different moisture Author: J. Boykin, S. Ray. Although drying cotton is good for cleaning, it can have adverse effects on the lint during subsequent processing, Valco says.
To assist in cleaning seed cotton, cotton fiber is dried to levels below 5 percent moisture content. If moisture is added back to the lint prior to the gin stand, studies have shown that ginners can reduce fiber breakage. — Moisture content: Percentage in selected samples of American- Egyptian seed cotton as received on truck or trailer at the gin, and at gin stand, after cleaning immediately prior to ginning, by gin equipment group and method of harvest, and ii Season and Texas -New Mexico gins, equipped — Central gins, e Arizona quipped.

Goals / Objectives The focus of this project plan is to establish a highly interactive research program that addresses agricultural quality related issues, with an emphasis on pre-harvesting with regards to operations that have a direct impact on quality of the harvested product, harvesting and post-harvest production and processing of cotton lint, cottonseed, and cotton .From early days of forming seed cotton modules, protection of the module was recognized as necessary while waiting to be ginned.
Canvas was used to cover the earliest modules, and the importance of that protection was demonstrated by the development of a standard for cotton modules that included the performance and design of canvas covers (ASAE, ).2B. Enhance extraction of non-fiber plant material from ginned lint.
