The most important factor in the intensification and rise of the production of the cotton industry in Tajikistan is the selection of new varieties characterized by high yield and its quality. The increase in the production of the cotton industry can be achieved not by expansion of acreage, since this possibility is very limited in a mountainous country, but by breeding new varieties of cotton and spreading them into production. The use of photosynthetic test characteristics in breeding contributes to the process of creating new varieties that meet the demand of agricultural production and the textile industry, i.e. varieties with a complex of economically useful features — precocity, high productivity, resistance to diseases and pests, optimal adaptive properties, characterized by high fiber yield and its technological quality. By methods of hybridization and selection by offspring on the basis of photosynthetic test characteristics from domestic and foreign variety samples, 28 introgressive genotypes were created that are characterized by complex of economically useful traits. It was found that out of the 28 genotypes of medium-fiber cotton studied by us, according to the main indicators of productivity — the number of full-fledged boxes per plant, the mass of raw cotton of one box and the yield — 6 genotypes were notable. The number of boxes per plant in the most productive was 12–15 pieces, the mass of raw cotton of one box is up to 6.6 g, and the yield of raw cotton is from 71.5 to 93.0 g/plant, which is significantly higher than in the standard Hisor variety.

Plastic contamination in US lint bales has increased with the adoption of new cotton harvesters that form cylindrical or round modules on the machine. It is of significant interest to the US cotton industry to reduce this contamination to preserve grower profitability and the reputation of the US as a reliable source of clean cotton fiber. The objective of this work is to describe the design and operation of a system for use on cotton gin module feeders that provides monitoring of plastic accumulation on the dispersing cylinders and video data to help document the module wrap condition and unloading/unwrapping procedures that may have caused the potential contamination event on the dispersing cylinders. In 2020, an integrated plastic contamination monitoring system was installed on module feeders at two commercial cotton gins in Texas. The system is comprised of sub-systems that provide images of plastic accumulation on the dispersing cylinders, a log of the processing sequence for round modules, video data of the unloading/unwrapping process for each module and a software program that integrates the data from the two sub-systems. The system was developed to operate on one computer, store the data in a common location, and simplify the process of extracting module specific data for a given event when plastic accumulates on the module feeder dispersing cylinders. The data provided by the system can be useful to manufacturers in comparing performance among module wrap products as well as to gin managers in training gin employees on module handling procedures to mitigate plastic contamination and improve worker safety.

<p>This thesis examines the port of Liverpool, its merchant community, and the growth of the raw cotton trade from its initial rise c. 1770 to the end of the Napoleonic period in 1815. By constructing a large database from Liverpool import lists published in Lancashire newspapers, combined with surviving cotton planter, merchant, and manufacturer papers, this thesis analyses: first, the rise of Liverpool as a major British cotton port and the geographical shifts in the port‘s cotton supply from the West Indies to Guyana, Brazil, and the United States; then second, the organisation of Liverpool‘s cotton trade in the Atlantic basin and at home. The port‘s cotton trade and the form of cotton procurement developed out of the pre-existing trading conditions prior to the cotton boom between Liverpool and each cotton cultivation region, and underwent major re-organisation in the early nineteenth century. Liverpool‘s cotton trade attracted new merchants who specialised in the import-export trade with one major region. Therefore, as cotton cultivation expanded from the West Indies to northern South America and the southern United States, the Liverpool market underwent a de-concentration from an oligopoly in the hands of few large cotton merchants to a more competitive market with many cotton importers. Ultimately, greater specialisation of Liverpool‘s cotton merchant and brokerage community resulted in increased efficiency in the importing, marketing, and selling of cotton on the British market, while a de-concentration of the Liverpool market provided the right market conditions to ward off artificially high prices, fostering the development of a cheap supply of raw cotton needed to sustain industrialisation of the British cotton industry in the nineteenth century.</p>

China, especially the Xinjiang cotton area, is facing severe agricultural water shortages, which seriously restrain the development of the cotton industry. Discovering cotton drought resistance genes and cultivating high-quality and drought-resistant cotton materials through molecular breeding methods are of great significance to the development of the cotton industry. In this study, the drought-resistant cotton material Xinluzhong NO.82 and the drought-sensitive cotton material Kexin NO.1 were used to identify a batch of drought-resistant candidate genes through whole transcriptome sequencing. The main research results obtained were as follows: the ceRNA (competing endogenous RNAs) network was constructed using full transcriptional sequencing to screen the core genes in the core pathway; two drought-related candidate genes were obtained. Gohir.A11G156000 was upregulated at 0 h vs 12 h and downregulated at 12 h vs 24 h. Gohir.A07G220600 was downregulated at 0 h vs 12 h and upregulated at 12 h vs 24 h. The results for drought-resistant materials and drought-sensitive materials were similar. Gohir.A11G156000, encoding GABA-T, which is homologous to POP2 in Arabidopsis thaliana, affects the drought resistance of plants by regulating the GABA content. Gohir.A07G220600 encodes L-aspartate oxidase, which is homologous to AO in Arabidopsis thaliana, and is involved in the early steps of NAD biosynthesis and in plant antioxidant reactions. This study confirmed that the use of gene expression regulatory networks can quickly screen reliable drought-resistance genes and can be used for subsequent gene function verification.

Effect of Different Doses of Compost on Growth and Yield of Cotton Cotton is main cash crop of Pakistan that is also called "white gold". Majority of farmers from Punjab and Sindh cultivate it and earn high value in market to improve their livelihood. It is very important crop for cotton industry and people because, it provide raw material to industry and job to workers who serve in this sector from sowing to harvesting,ginning to weaving and selling. Cotton sector play important role in National economy as it is also a rich source of edible oil. In current scenario, growing cotton is becoming costly due to use of expensive inputs. To play part in reducing input cost of cotton present study conducted. The study aimed to evaluate efficacy of compost developed from crop refuse at zero cost. For this purpose performance of three cotton varieties MNH 886, FH 142 and IR 901 checked at five doses100 Kg, 200 Kg, 300 Kg, 400 Kg and 500 Kg of compost per acre. Results revealed that MNH 886 performed good among all three varieties on all doses followed by FH 142 and IR 901 respectively. MNH 886 performed good than all others, where maximum seed germination recorded 72.67%, plant height 138.93 cm, root length 35.43 cm, numbers of branches11.56, numbers of bolls 45.78 and yield 1840 Kg per acre on 500 Kg compost per acre recorded.However, minimum seed germination 48.56%, plant height 93.02 cm, root length 25.24 cm, numbers of branches 8.67, numbers of bolls 11.89 and yield was recorded 1042 Kg on 100 Kg compost per acre. Same trend of maximum growth at 500 Kg and minimum at 100 Kg compost observed on FH142 and IR901.

The textile sector produces yearly great quantities of cotton byproducts, and the major part is either incinerated or landfilled, resulting in serious environmental risks. The use of such byproducts in the composite sector presents an attractive opportunity to valorize the residue, reduce its environmental impact, and decrease the pressure on natural and synthetic resources. In this work, composite materials based on polypropylene and dyed cotton byproducts from the textile industry were manufactured. The competitiveness of the resulting composites was evaluated from the analyses, at macro and micro scales, of the flexural modulus. It was observed that the presence of dyes in cotton fibers, also a byproduct from the production of denim items, notably favored the dispersion of the phases in comparison with other cellulose-rich fibers. Further, the presence of a coupling agent, in this case, maleic anhydride grafted polypropylene, enhanced the interfacial adhesion of the composite. As a result, the flexural modulus of the composite at 50 wt.% of cotton fibers enhanced by 272% the modulus of the matrix. From the micromechanics analysis, using the Hirsch model, the intrinsic flexural modulus of cotton fibers was set at 20.9 GPa. Other relevant micromechanics factors were studied to evaluate the contribution and efficiency of the fibers to the flexural modulus of the composite. Overall, the work sheds light on the potential of cotton industry byproducts to contribute to a circular economy.
