Granular and liquid commercial humates, with micronutrients, and a microbial fermentation product were compared in several combinations with nematicides for their effects on cotton lint yield and root-knot nematode suppression. Fumigant nematicides effectively reduced cotton root galling caused by root-knot nematodes, and cotton lint yields increased. Organophosphates and carbamates were not ef...

Reintroductions of the boll weevil, Anthonomus grandis grandis Boheman, into areas of the United States where it has been eradicated or suppressed are very expensive to mitigate. There is concern that a cotton gin in an eradication zone may serve as a site of boll weevil reintroductions when processing cotton harvested in a neighboring infested zone. Similarly, there is a question whether weevi...

An experimental cotton color/trash meter was developed previously for the purpose of improving cotton color measurement by removing trash-particle effects on color measurement with image processing. In this work, the experimental meter was tested extensively on a large number of cotton samples varying widely in color and trash content. Testing involved: (1) comparing the measurement accuracy of...

Cotton quality, a major factor determining both cotton profitability and marketability, is affected by not only the overall quantity of but also the type of the foreign matter. Although current commercial instruments can measure the overall amount of the foreign matter, no instrument can differentiate various types of foreign matter. The goal of this study was to develop a hyperspectral imaging...

One of the main hurdles standing in the way of optimal cleaning of cotton lint isthe lack of sensing systems that can react fast enough to provide the control system withreal-time information as to the level of trash contamination of the cotton lint. This researchexamines the use of programmable graphic processing units (GPU) as an alternative to thePC's traditional use of the central processin...

irrigation water and nitrogen fertilizer are two important factors in increasing the yield and yield components of cotton. in order to evaluate effects of irrigation methods, various levels of water and nitrogen fertilizer on yield and yield components of cotton were studied at hashemabad cotton research station of gorgan in 2008. the experiment was conducted in split-split plots design with th...

"Pre-separator plus1D2D cyclone" and "pre-separator plus 1D3D cyclone" systems were tested with ground gin trash, which contains 10.35% lint fiber and 5.49% fine dust (less than 100 μm). Test results indicate that the pre-separator collected gin trash at over 97% collection efficiency. There were no significant differences in emission concentrations and overall collection efficiencies from thes...

Wheat–cotton double cropping practices on a large scale in cotton belt of the Yellow RiverValley and the Yangtze River Valley in China. Field experiments were conducted to determinethe effects of wheat–cotton double cropping on cotton biomass accumulation and yieldformation during 2011/12 and 2012/13 growing seasons. Two cotton cultivars, Siza 3 (mid–latematurity) and CCRI 50 (early maturity), ...

The present investigation on correlation and path analysis studies helps to study the relationship among yield contributing traits along with quality parameters. observations were taken in F1 population of 35 hybrids lines (7 lines) testers (5 testers) for viz. plant height (cm), number sympodial branches per plant, bolls boll weight (g), lint index single cotton ginning outturn (%), upper half...
