This article presents the results of an analysis of studies on the variability of the trait of plant productivity and its components in cotton F1 hybrids, obtained on the basis of complete diallel crossing of dwarf, low-growing lines with tall cotton varieties of the species G. hirsutum L. It was revealed that in F1hybrids according to the harvest of raw cotton and its constituent elements, it varies differently depending on the genotypes of the parent components and combinations of crosses. Moreover, in F1 hybrids, a sign of the productivity of plants and its components shows dominance and overdomination of the signs of better and worse parents, aswell as an intermediate type of inheritance. It has been established that the indicator of the number of bolls and the yield of raw cotton per plant in tall varieties is controlled mainly by dominant genes, and the raw mass of one box of these varieties is controlled mainly by recessive genes

Abstract:
AbstractThis article revisits the idea of “cotton imperialism” in Britain, showing that metropolitan support for cotton projects in the British Empire was uneven. Using the records of the British Cotton Growing Association's (BCGA) fund-raising campaign of 1902–1914, the article shows that “empire cotton” did not receive widespread support in Britain. In Lancashire, some cotton capitalists financed the movement for empire cotton, but many others refused to participate. Investors were uninterested in the BCGA's business model despite their interest in other cotton projects. To make matters worse, the BCGA became a tool for politicians on both sides of the Tariff Reform controversy. Textile workers were the only major segment of the British population to accept the BCGA's claims about the value of empire-grown cotton for Britain. Their support for imperial development was, however, limited and pragmatic. The BCGA's struggle to raise money for empire cotton shows the importance of grounding the rhetoric of empire in empirical findings: in the face of the Lancashire lobby's vocal campaign for empire cotton, Britons in general were reluctant to pay for it themselves.

Abstract:
The fibre physical properties can be influenced by non-cellulosic and metal contents present in it which ultimately may impact the quality and spinning performance of resultant yarn. The concentration of these materials largely depends upon cotton variety, growing area and atmospheric conditions. In this back drop the present research study was planned to investigate the impact of various varieties and locations on non-cellulosic and metal contents of raw cotton and their eventual effects on subsequent yarn quality. So four varieties of single-season upland cottons from four different cotton-growing locations in Pakistan were selected for the study. The collected cotton samples were subjected to chemical and physical testing to know the concentrations of non-cellulosic and metal contents present in them along with other physical parameters. Then they were subjected to yarn manufacturing by conventional ring spinning method. At the end the yarn quality testing was carried in respect of its tensile and imperfections characteristics. The results disclosed significant impacts of selected variables on yarn quality. The reduction in non-cellulosic contents and metal contents put negative impact on Count Lea Strength Product (CLSP), yarn lea strength, single yarn strength, breaking length, evenness, thin spots, and neps count of resultant yarn.

Abstract:
The boll weevil, Anthonomus grandis grandis Boheman (Coleoptera: Curculionidae), is one of the key pests and limiting factors to cotton production in conventional and organic systems. We assessed the use of resistant and susceptible cotton cultivars, a neem-based insecticide (Natuneem), and trapping with an A. grandis grandis aggregation pheromone as possible control tactics. In the first of two growing seasons we evaluated resistance of colored fiber cotton cultivars BRS 200, BRS Rubi, BRS Safira, and BRS Verde, and white fiber cotton BRS Aroeira, against A. grandis grandis attack. In the second growing season we assessed three colored cotton cultivars grown in and without close association of BRS Aroeira, and two control tactics: the neem-based pesticide and trapping. Because BRS Aroeira showed resistance against A. grandis grandis in the first growing season, it was selected to be planted in close association with more susceptible colored cultivars in the second growing season. Field plots with white and colored cotton cultivars reduced the need to control A. grandis grandis using the neem-based pesticide. Control by the neem-based pesticide and by trapping were of comparable value although the traps provided measurable control during early cotton growth stages and the neem-based pesticide provided measurable control during later cotton growth stages.

Abstract:
AbstractA survey was conducted in 47 locations in nine cotton-growing states of India to identify the composition of mealybug species occurring on cotton. Results of the taxonomic study showed that two mealybug species, the solenopsis mealybug, Phenacoccus solenopsis (Tinsley), and the pink hibiscus mealybug, Maconellicoccus hirsutus (Green), were found to infest cotton plants from all nine cotton growing states of the country. However, P. solenopsis was found to be the predominant mealybug species, comprising 95% of the samples examined. P. solenopsis, which was hitherto not reported to occur in India, now appears to be widespread on cotton in almost all cotton-growing states of the country. P. solenopsis is an exotic species originated from the USA and was reported to damage cotton and crops of 14 families. This report discusses the implications of the introduction of this exotic polyphagous pest species and the necessary steps to mitigate its potential threat to agriculture in India.

Abstract:
This article provides an historical account of small-holders’ cotton growing and marketing in an area of colonial Tanzania known as the Western Cotton Growing Area. Covering the period from 1920-1960, the article focuses on the colonial government’s efforts to promote cotton growing and marketing, which included establishment of relevant legislation and enforcement of such laws and related regulations. The article reveals that the colonial policies and legislation on cotton production and marketing favoured Indian merchants and facilitated exploitation of African producers. As a result, during the 1940s and 1950s the African producers formed associations that brought them together in the effort to pressurise the colonial administration to allow formation of Africans’ cotton marketing societies. This effort was supported by local chiefs, and in due course it resulted in remarkable achievements; such that by 1954 the societies were handling one-third of the total crop successfully. By 1960 they had established monopoly in the marketing of cotton in the entire area.

Abstract:
Cotton varieties that are high yielding and resistant to pests are required to improve production and productivity and to capitalize on the crop’s enormous potential and its critical role in Ethiopia’s expanding textile industry. Lack of improved cotton technology has forced farmers to recycle local varieties for ages which have become very susceptible to pests which are the major causes of very low productivity and quality of cotton in the country. Among major pests, bollworms (Helicoverpa armigera and Pectinophora gossypiella) account for 36–60% of yield losses. In the absence of genetically resistant or tolerant varieties, genetically engineered bollworm-resistant Bacillus thuringiensis (Bt) cotton has offered a great opportunity to reduce crop losses from bollworms. The objective of the study was to evaluate the efficacy of bollworm resistance and adaptability of Bt cotton varieties across cotton growing environments in Ethiopia and provide recommendations. Two Bt cotton hybrids (JKCH 1947 and JKCH 1050), one Bt OPV (Sudan), and three OPV conventional varieties (Weyito 07, Stam-59A, and Deltapine-90) were evaluated at seven different agro-ecologies using a randomized complete block design (RCBD) with three replications. Results showed significant differences among genotypes for yield and other traits. Hybrids JKCH 1947 and JKCH 1050 were the top high yielders under high and mild bollworm infestations, with mean seed cotton yield of 3.10 t·ha−1 each and lint yield of 1.20 and 1.19 t·ha−1, respectively, whereas the standard check Deltapine-90 (popular variety) recorded a mean seed cotton and lint yield of 2.3 t·ha−1 and 0.8 t·ha−1, respectively. Combined analysis showed that genotypes, environment, and the genotypes × environment interactions had a highly significant effect ( P < 0.05) on fiber quality. Weyito 07 and the two hybrids (JKCH 1947 and JKCH 1050) had upper half mean fiber lengths in the range of 27.78 to 32.11 mm. For fiber strength, genotypes Weyito 07, JKCH 1050, Stam-59A, and JKCH 1947 had 33.50 g/tex, 28.59 g/tex, 28.00 g/tex, and 27.75 g/tex, respectively. The fiber quality values of the hybrids were within acceptable limits, with staple lengths ranging from 27.78 to 28.44 mm and fiber strengths ranging from 27.75 to 28.59 g/tex. Results show potential adaptation of the hybrids under different cotton growing environments and their superior yield performance due also to added protection of yield losses from damage by bollworms. The contrast is bigger under high insect pressure conditions due to the genetically engineered Bt trait compared to the conventional varieties. The effective field resistance against bollworms in most locations shows that wider use of these hybrids can enhance cotton productivity and quality in Ethiopia.

Abstract:
Farmers in the Chattogram Hill Tracts, Bangladesh have been growing cotton (Gossypium hirsutum L.) in their traditional system of jhum cultivation which is undergoing transformation. Growing rainfed cotton as a monocrop in the uplands is constrained by farmers’ socio-economic conditions and erratic rainfall. Shifting growing season to post-monsoon dry monthscould be an option to sustain cotton production in hilly areas. An exploratory experiment was conducted for two seasons to explore the possibility of growing cotton in valley lands in Bandarban during dry season. Growth and yield potentials of dry season cotton were evaluated in relation to prevailing environmental conditions. Night temperature dropped to 9oC on several occasions in 2018-2019 season; but it remained higher than 11oC throughout the season in 2019-2020. In 2018-2019, day temperatures surged higher past March 15 occasionally exceeding 38oC. Variability in temperatures was more in 2018-19 while average temperatures were higher in 2019-20 season. Rainfall distribution was almost similar in both the growing seasons receiving total rainfall of 757 mm and 579 mm in two seasons, respectively. Higher seed cotton yield (2,047 kg per ha) was recorded for 15 November planted crop compared with 1 December planted crop (1,186 kg per ha). December 1 planted crop was affected more by low temperatures at seedling stage resulting in poor growth and fewer bolls per plant. Late planted crop was more vulnerable to rain damage at boll opening stage. Crops of both the seasons encountered high temperatures (>32oC) during boll development. Changing climate, shorter winter season and rising temperatures may allow cotton production in valley lands shifting growing season from rainy season to post-monsoon dry months. However, the window of dry season cotton growing in Bandarban, Bangladesh seems narrow. Rainfall pattern restricts planting seeds prior to mid-November. Again, high temperatures stress in March and April synchronizing boll development, and rainfall toward late April and May during boll opening may cause yield loss. Development and adoption of short duration, low temperature tolerant upland cotton varieties might be of advantage for adapting to climate change vulnerabilities. Ann. Bangladesh Agric.

Among all the surveyed districts of Haryana the maximum mean disease incidence was recorded in Fatehabad (18.25%) followed by Sirsa (15.25%), Hisar (15.42%), While the minimum disease incidence was recorded Charkhi dadri (9.08%). Conclusion: The results of the current study showed that important cotton-growing regions in Haryana have root rot disease incidence. It is clear from the overall study that root rot disease is common in significant mulberry-growing regions in Haryana. As a result, resistant cotton types are urgently needed to address the grower's issue, together with the best management techniques, such as effective biocontrol agents that can significantly reduce the illness. Consequently, research should be conducted to ascertain the incidence of the disease in different places.

Abstract:
Cotton fiber, which is the most widely used natural fiber in the textile and paper industries, has a crucial environmental impact. Cultivation of conventional cotton consumes a lot of water and requires the usage of a higher amount of pesticides. Organic cotton is a more environmentally friendly alternative to its growing conditions. The characteristics of cotton change with the differences in growing conditions. In this study, the properties of yarns obtained from both conventionally and organically grown cotton were tested and analyzed. The properties of these yarns in the fabric structure were compared in terms of fabric performance. The produced fabrics were dyed in the cold-pad batch method with 5 different colors of reactive dyes, which are the most demanding colors in the ready-made garment industry. The physical properties and the fastness test results of the dyed organic and conventional cotton fabrics were investigated in detail to highlight the plant growing effects on the fabric behavior. Comparative color analysis and evaluation of the fabrics were made to discuss the performance of the fabrics. It is found that organically grown cotton is not only superior in quality but also has no negative eff ECT on fabric properties.

Abstract:
The Turkestan region is a cotton-growing zone in South Kazakhstan, but also the northernmost cotton-growing area in the world. Annually, medium-staple cotton (Gossypium hirsutum L.) cultivation occurs on 115,000–125,000 ha, with 80,000–85,000 ha grown in the Districts of Maktaaral and Zhetysay, Kazakhstan. This region is highly susceptible to salinity, drought, invasion of dangerous pests (cotton budworm, beet borer, spider mites, and aphids), and diseases (fusarium blight [wilt] and gummosis). An extremely high salt content and aridity in the arable soil are the main limiting factors of that region, hence, genotype selection through genetic principles is the most effective and economical way to reduce their negative impacts on vegetation. Therefore, the research on developing resistant cotton cultivars suitable for such soil and climatic conditions is most relevant. Considering the above situation, assessment of newly developed high-yielding cotton cultivars with fiber quality of types III–IV for tolerance to heat and drought, salinization, and pests and diseases ensued during 2019, 2020, and 2021 at the Agricultural Experimental Station of Cotton and Melon Growing, Atakent, Kazakhstan. Their promising cotton genotypes resulted from strains developed through intraspecific and interspecific diallel hybridization. The newly developed eight cotton cultivars, grown on more than 92% of the hectarage in the Southern region of Kazakhstan, are PA-3031, PA-3044, M-4005, M-4007, M-4011, Bereke-07, Myrzashol-80, and M-4017.

Abstract:
Dryland and irrigated field experiments were established to measure differences in soil water relations throughout the growing season between plots in which cotton was grown with and without silverleaf nightshade interference. Soil moisture readings were taken weekly at 15-cm increments to a maximum depth of 120 and 150 cm during 1984 and 1985, respectively. When cotton was grown with silverleaf nightshade, soil water loss was greater at the lower portion of the soil profile earlier in the growing season than when cotton was grown alone. In the irrigated environment in 1985 when precipitation was higher than normal and the soil moisture content remained above normal, soil water loss did not differ. Cotton lint yield, plant height, and boll size reflected the amount of soil moisture available for growth and development of the crop. A statistical technique for quantifying soil water relations between the crop growing alone and growing with interference from the weed is demonstrated.

Abstract:
Cotton root rot, caused by the fungus Phymatotrichopsis omnivora, is a serious and destructive disease affecting cotton production in the southwestern United States. Accurate delineation of cotton root rot infections is important for cost-effective management of the disease. The objective of this study was to use airborne multispectral imagery for monitoring the progression of root rot infections within cotton fields during a growing season. A number of cotton fields near Edroy and San Angelo, Texas were selected for this study. Airborne multispectral digital imagery with blue, green, red and near-infrared bands was taken from these fields two to four times during the 2010 growing season. The imagery for two fields from each of the two locations was georeferenced and classified into two to twenty spectral classes using unsupervised classification techniques. The optimal number of spectral classes was determined based on the average transformed divergence for each classification and the spectral classes were then grouped into root rot-infected and non-infected zones. The infected areas within each field were determined for each imaging date and compared among the different dates. Both airborne imagery and ground observations showed that cotton root rot expanded in different patterns and at different rates over the growing season. Toward the end of the growing season, the percentage of root rot-infected areas increased to 13.2% and 26.8% in the two fields in Edroy, and to 37.8% and 50.6% in the two fields in San Angelo. The results from this study will be useful for the understanding of the progression of the disease and for the development of site-specific treatment plans for the disease.

Abstract:
Benghal dayflower (formerly known as tropical spiderwort) is one of the most troublesome weeds in Georgia cotton. Field studies were conducted from 2003 to 2005 to evaluate the relationship between the duration of Benghal dayflower interference and cotton yield to establish optimum weed-control timing. To determine the critical period of weed control (CPWC), Benghal dayflower interference with cotton was allowed or prohibited in 2-wk intervals between 0 to 12 wk after crop planting. Maximum yield loss from Benghal dayflower in May-planted cotton was 21 to 30% in 2004 and 2005, whereas cotton planting delayed until June resulted in maximum yield losses of 40 to 60%. June-planted cotton had a CPWC of 190 to 800 growing degree days (GDD) in 2004 (52-d interval beginning at 16 d after planting [DAP]) and 190 to 910 GDD in 2005 (59-d interval beginning at 18 DAP). In contrast, May-planted cotton in 2005 had a narrower CPWC interval of 396 to 587 GDD (18 d) that occurred 3 wk later in the growing season (initiated at 39 DAP). May-planted cotton in 2004 did not have a critical range of weed-free conditions. Instead, a single weed removal at 490 GDD (44 DAP) averted a yield loss greater than 5%. It is recommended that fields infested with Benghal dayflower be planted with cotton early in the growing season to minimize weed interference with the crop.

Abstract:
This paper scrutinizes the process of extracting or separating fiber from seed, which is viewed as one of the milestones in cotton-ginning plants, reviews a series of implemented experiments, presents results, and offers solutions. Increasing demand for cotton produce across the globe leads to large-scale research work to improve the technique and technology of primary cotton processing and to establish their scientific basis in major cotton-growing economies. In this regard, it is becoming important, among other things, to develop mathematical models of processes, boost the productivity of cotton processing machines by means of optimization methods, create efficient working bodies, preserve natural quality indicators of the cotton fiber obtained through improved operational characteristics of machines, and reduce production costs. At the same time, the issues of the development of resource efficient designs of working bodies that won’t negatively affect the quality of products and the justification of the parameters of the sewing machine seem relevant for all cotton-growing economies.

Full text
Abstract:
In this research, fractal properties of a cell wall in growing cotton fibers were studied. It was found that dependences of specific pore volume (P) and apparent density (ρ) on the scale factor, F = H/h, can be expressed by power-law equations: P = Po F(Dv−E) and ρ = ρo F(E−Dρ), where h is minimum thickness of the microfibrilar network in the primary cell wall, H is total thickness of cell wall in growing cotton, Dv = 2.556 and Dρ = 2.988 are fractal dimensions. From the obtained results it follows that microfibrilar network of the primary cell wall in immature fibers is loose and disordered, and therefore it has an increased pore volume (Po = 0.037 cm3/g) and low density (ρo = 1.47 g/cm3). With enhance days post anthesis of growing cotton fibers, the wall thickness and density increase, while the pore volume decreases, until dense structure of completely mature fibers is formed with maximum density (1.54 g/cm3) and minimum pore volume (0.006 cm3/g). The fractal dimension for specific pore volume, Dv = 2.556, evidences the mixed surface-volume sorption mechanism of sorbate vapor in the pores. On the other hand, the fractal dimension for apparent density, Dρ = 2.988, is very close to Euclidean volume dimension, E = 3, for the three-dimensional space.

Abstract:
AbstractField populations of the cotton aphid, Aphis gossypii Glover, are structured into geographically widespread host races. In the cotton-producing regions of West and Central Africa (WCA), two genotypes have been repeatedly detected within the cotton host race, one of which (Burk1) is prevalent (>90%) and resistant to several insecticides, as opposed to the second one (Ivo). Here, we conducted whole plant and field cage experiments to test hypotheses for such low genetic diversity, including selection from insecticide treatments, interclonal competition and adaptation to host plant, or climatic conditions. To assess the genetic diversity of immigrant aphids, alatae were trapped and collected on cotton and relay host plants (okra and roselle) in the early cropping season. Individuals were genotyped at eight specific microsatellite loci and characterized by a multilocus genotype (MLG). When independently transferred from cotton (Gossypium hirustum L.) leaf discs to whole plants (G. hirsutum and G. arboreum, roselle and okra), Ivo and Burk1 performed equally well. When concurrently transferred from cotton leaf discs to the same plant species, Ivo performed better than Burk1, indicating that competition favoured Ivo. This was also the case on G. hirsutum growing outdoors. Conversely, Burk1 prevailed when cotton plants were sprayed with insecticides. In experiments where aphids were allowed to move to neighbouring plants, Burk1 was better represented than Ivo on low-populated plants, suggesting that dispersal may be a way to avoid competition on crowded plants. Most cotton aphids collected on cotton or relay host plants in the early cropping season were Burk1 (>90%), indicating high dispersal ability and, probably reflecting high frequency on host plants from which they dispersed. In the agricultural landscape of WCA, the use of broad-range insecticides on both cotton and relay host plants has led to the prevalence of one genotype of A. gossypii resistant to different classes of insecticides. Deployment of widespread and integrated pest management strategies are needed to restore cotton aphid control.

Abstract:
Herbicide-resistant Palmer amaranth has become the most economically detrimental weed of cotton in the southeast United States. With the continual marginalization of potential herbicide tools, research has expanded to include alternative means of affecting future Palmer amaranth populations by altering safe sites and reducing inputs to the seedbank population. The influence of delayed Palmer amaranth establishment on seed production potential has not been investigated in the southeast United States. Studies were conducted to evaluate the influence of time of Palmer amaranth establishment on morphology, growth, and seed production. The experiment was a factorial, with five levels of Palmer amaranth transplanting (0 to 12 wk after cotton planting) and two levels of crop type (cotton and noncrop). In the absence of crop competition, the first cohort of Palmer amaranth produced 446,000 seeds per plant. This potential seed production was reduced 50% when Palmer amaranth plants were established nearly 6 wk later. In contrast, the first Palmer amaranth cohort growing in competition with cotton produced 312,000 seeds, 30% less than was produced in the absence of competition. Interference from cotton shifted time to 50% seed production to nearly 4 wk earlier in the growing season, relative to plants without crop competition. Delayed establishment of Palmer amaranth simulates premature loss of herbicide efficacy and alters the competitive balance between cotton and Palmer amaranth. Although the planting time that resulted in 50% reduction in Palmer amaranth plant height at the end of the season was not affected by the presence of cotton, 50% reduction in plant width and biomass occurred within the first 3.8 wk of the growing season when growing with cotton, more than 4 wk earlier than Palmer amaranth growing without a crop. This suggests that early season weed control programs will have a large effect on Palmer amaranth potential growth and seed production, as well as crop yield. To implement soil seedbank reduction strategies effectively, information on mechanisms that regulate Palmer amaranth persistence in the soil seedbank is needed.

Abstract:
In Alabama, typically, a three-wk period is required after rolling down a cover crop to achieve termination rates >90%, and to eliminate competition for water between the cover crop and cash crop. Cover crop termination can be sped up by applying herbicides during the rolling process. However, for organically grown cotton, synthetic herbicides cannot be used. This experiment evaluated the effectiveness of terminating two cover crops using a roller/crimper alone and with glyphosate, or two organic herbicides at different application rates to determine the effects of cover crop termination practices on cotton population and yield. In the three growing seasons, rye termination rates were between 99% and 100% for all rolling treatments three wk after rolling. Similar rates were generated for crimson clover but only in 2011, as crimson clover termination rates in two yr were lower. Organic herbicides did not increase cover crop termination compared with glyphosate and roller alone. In 2009 there was no difference in cotton population following rye and crimson clover. In 2010, cotton population following clover was higher than with cereal rye, although, in 2011, cotton population following rye was higher compared to crimson clover. In three growing seasons, seed cotton yield following rye was significantly higher compared to crimson clover. In 2010, rainfall deficit and high temperatures negatively impacted cotton growth and substantially reduced yields compared to 2009. Overall, rolling treatments did not affect cotton population and yield. In contrast, cotton population and yield were affected by different weather conditions during 2009, 2010, and 2011 growing seasons.

This paper presents a bibliographical analysis of scientific research on cotton-picking machinery, focusing on countries, years, authors, and publishers involved in this field. The study utilizes materials from the Scopus database, describing the sequence of analyses and presenting the results through graphs and histograms. Cotton is a crucial product for human life, and its ecologically clean demand is increasing yearly. Traditional cotton growing remains relevant in Uzbekistan, where cotton picking by machine is essential due to labor-intensive and expensive manual methods. The international cotton industry actively participates in creating and using cotton-picking machines, with more than 90 countries growing cotton on 32 million hectares, including Uzbekistan’s 1.07 million hectares. Since the 1970s, the USA and Uzbekistan have been the primary countries improving cotton-picking machines based on scientific and practical research. However, by the 21st century, countries like China, India, Turkey, and Israel have joined this field. This study aims to ensure that cotton-picking machines produced in Uzbekistan meet state standards by analyzing scientific research in this field, studying the advantages and disadvantages of machines from various countries, and staying updated on the latest developments through the Scopus database.

Dependable rainfall at 75% probability prevailed from 24 to 38 standard week. The budgeting of water showed that there was no deficit of soil moisture until 37 standard week during two years study. Long duration crop of cotton intercropped with early maturing cowpea, greengram or blackgram significantly enhanced seed cotton equivalent yield over sole cotton. The rainfall in the later period was short of actual evapotranspiration. Therefore intercrops of longer duration viz., sesamum maturing in 75 days, soybean in 91 days and groundnut in 105 days were highly competitive and did not increase the seed cotton yield equivalents over the sole crop.

Abstract:
Mid-South United States (US) cotton producers are now rotating cotton (Gossypium hirsutum L.) with other crops such as corn (Zea mays L.) or soybean [Glycine max (L.) Merr.] , in response to economic conditions, rather than growing cotton continuously as was the tradition. This research investigated cotton growth and development, lint yield, and fiber quality when cotton was grown following soybean compared to following cotton. Cotton and soybean were grown in six rotational sequences (CCCC, SSSS, CSCS, CSSC, SCSC, and SCCS) during 2012-2015 at Stoneville, MS. These rotations were imposed in production systems utilizing either transgenic or conventional cultivars, with or without glyphosate in the herbicide regime. Dry matter partitioning, leaf chlorophyll (Chl) concentration, lint yield, and fiber quality data were collected. Years when cotton was grown following soybean, produced cotton plants that were on average 13% taller, intercepted on average 6% more sunlight, and contained 13% greater leaf Chl concentrations compared to plants in continuous cotton. Cotton grown following soybean produced increased yields one of the two years. Fiber quality was not impacted by the different rotation sequences. Cotton grown in a conventional production system was competitive with that grown in a transgenic production system. The yield increase observed when growing cotton in rotation with soybean is possibly due to increased soil N via N-fixation from the prior soybean crop and/or due to altered soil microbial populations favorable to the subsequent cotton crop.

The Turkestan region is a cotton-growing zone in the south of Kazakhstan, which is the northernmost cotton-growing zone in the world. 115-125 thousand hectares of medium-staple cotton (Gossypium hirsutum L.) are cultivated here annually, of which 80-85 thousand hectares are sown in the Maktaaral and Zhetysay districts. This region is highly susceptible to salinity, drought, invasion of dangerous pests (cotton budworm, beet borer, spider mites, aphids), and diseases (fusarium blight (wilt), gummosis). Considering the high salt content in the arable soil horizon, the aridity of the climate of the Turkestan region are the main limiting factor of the region, and selection and genetic methods is the most effective and economical way to reduce their negative impacts on cultivated vegetation, then research work on the study and creation of new resistant cotton varieties in these soil and climatic conditions are relevant. Considering all the above problems, scientists of the Agricultural Experimental Station of Cotton and Melon Growing LLP have set themselves the goal of creating heat- and drought-resistant, precocious cotton varieties with high productivity, resistance to salinization, diseases, pests, possessing high technological qualities as the yield and quality of fiber of types III-IV, based on previously obtained ones during hybridization of intraspecific and interspecific lines of families. For 30 years, scientist-breeders of Kazakhstan have created 13 varieties of medium-fiber cotton, of which 8 are approved for use in the Turkestan region in the Republic of Kazakhstan. The research method is based on hybridization, multiple selection, and testing of offspring by the half method, according to the full diallel scheme (first Griffing model for F1). The created seven varieties PA-3031, PA-3044, M-4005, M-4007, M-4011, Bereke-07, Myrzashol-80, and M-4017 are zoned for more than 92% of the acreage in cotton-growing farms in the south of Kazakhstan, for the variety M-5027, which is resistant to pests, the patent has been issued 2021 and in 2022 it is planned to enter it into the register of approved varieties.

Abstract:
AbstractCotton growing landscapes in Australia have been dominated by dual-toxin transgenic Bt varieties since 2004. The cotton crop has thus effectively become a sink for the main target pest, Helicoverpa armigera. Theory predicts that there should be strong selection on female moths to avoid laying on such plants. We assessed oviposition, collected from two cotton-growing regions, by female moths when given a choice of tobacco, cotton and cabbage. Earlier work in the 1980s and 1990s on populations from the same geographic locations indicated these hosts were on average ranked as high, mid and low preference plants, respectively, and that host rankings had a heritable component. In the present study, we found no change in the relative ranking of hosts by females, with most eggs being laid on tobacco, then cotton and least on cabbage. As in earlier work, some females laid most eggs on cotton and aspects of oviposition behaviour had a heritable component.

Abstract:
Cotton contributes 0.6% to the value added in GDP and 3.1% to the value added in the agriculture sector of Pakistan. The dusky cotton bug (DCB), Oxycarenus hyalinipennis (Hemiptera: Lygaeidae), is among the insect pest species of highest economic significance in cotton production in the country. Adults and nymphs feed on seeds and cotton bolls, affecting seed germination. The dusky cotton bug is a polyphagous insect that feeds on a variety of host plants. Its adults and nymphs typically feed on squares of the cotton plant, resulting in a pale yellow color of squares and subsequent shedding of infested squares. Insecticide resistance in cotton insect pests is an emerging threat to sustainable cotton production in Pakistan. A thorough understanding of resistance might be a valuable tool for implementing pest control approaches. In the present study, Clothianidin, Fipronil, Bifenthrin, Triazhophos, Deltamethrin, and Clothianidin + Imidacloprid insecticides were used in different cotton-growing districts of Punjab. Among all the insecticides used for controlling the DCB population, Clothianidin + Imidacloprid was found to be the most effective in all districts, while Deltamethrin was the least effective in District Khanewal, Bifenthrin in Dera Ghazi Khan, Rahim Yar Khan, and Vehari, and Clothainidin in Multan. Therefore, we recommend the use of a pesticide mixture (Clothianidin + Imidacloprid) as a beneficial strategy against the dusky cotton bug in various cotton-growing districts of Punjab.

Abstract:
Cotton is very valuable technical crop. This crop keeps its strategical significance still its cultivation. In order to produce high yields of new certificated cotton varieties while maintaining their potential by cultivating them for a long period of time in production, it is necessary to properly analyze their biological characteristics, soil and climatic conditions, i.e. plant density, irrigation regime and fertilizer norms. As a result of research, it became clear that increasing yield and improving its quality products depends not only on the variety, but also on the agrotechnical measurements provided to get it. So, if the agronomic technology of cultivation of each variety is not known, productivity gradually decreases, quality indicators deteriorate and the variety loses its properties. The research work had been conducted in 2018-2019 in Ganja-Kazakh region with the variety "Ganja-160" at 2 plant densities – 60x15-1 and 60x20-1 plants, 2 fertilizer norms – N90P100, N120P100 kg of active substance and at 2 irrigation regimes 65-65-65%; 70-70-65%. At the results of the research, it is defined that when introducing N90P100 kg/ha (active substance) 60 x 15-1plant density and 65-65-65% irrigation regime it was received 39,2 sent/ha of yield in an average.

HighlightsSoil water depleted by the cover crop was quickly replenished by spring precipitation.Higher soil water was maintained during the cotton growing season under the cover crop treatment.Cover crops improved soil organic carbon under both irrigated and dryland conditions.Cover crops enhanced crop water productivity under both irrigated and dryland conditions.Abstract. Cover crops provide many soil health benefits to agricultural systems. An interest in growing cover crops in cotton (Gossypium hirsutum L.) production systems has been increasing in the Texas Rolling Plains (TRP) region. Due to limited rainfall and groundwater availability, producers in this semi-arid region are concerned that winter cover crops can reduce soil water availability for a subsequent cotton crop. In addition, the long-term effects of cover crops on soil organic carbon (SOC) are not well studied in this region. The overall goal of this study was to assess the long-term effects of growing a winter wheat (Triticum aestivum) cover crop on soil water, SOC, seed cotton yield, and crop water productivity (CWP) under irrigated and dryland cotton production systems using the Decision Support System for Agrotechnology Transfer (DSSAT) model. Measured data from cover crop experiments conducted at the Texas A&amp;M AgriLife Research Station at Chillicothe from 2011 to 2020 were used to evaluate the CROPGRO-Cotton and CERES-Wheat modules in the DSSAT Cropping System Model. The average percent error (PE) between the simulated and measured seed cotton yield was 0.3% and -0.9%, and that between the simulated and measured aboveground wheat biomass was 1.4% and -3.4% during the calibration and evaluation periods, respectively. For the simulation of SOC, the PE was 8.5% and 7.6% during the calibration and evaluation periods, respectively. Long-term (2001 to 2020) simulations showed that soil water was reduced substantially by the winter wheat cover crop before its termination. However, depleted soil water was quickly replenished by spring precipitation and maintained at a higher level during the cotton growing season. Winter wheat cover crops can potentially improve SOC in irrigated and dryland cotton production systems. The CWP of cotton also improved with a winter wheat cover crop under both irrigated and dryland conditions. We concluded that cover crops could potentially improve soil health and provide a sustainable environment for TRP cotton production.

Abstract:
An outbreak of a new disease occurred in cotton (Gossypium hirsutum) fields in northwest Argentina starting in the 2009–10 growing season and is still spreading steadily. The characteristic symptoms of the disease included slight leaf rolling and a bushy phenotype in the upper part of the plant. In this study, we determined the complete nucleotide sequences of two independent virus genomes isolated from cotton blue disease (CBD)-resistant and -susceptible cotton varieties. This virus genome comprised 5,866 nucleotides with an organization similar to that of the genus Polerovirus and was closely related to cotton leafroll dwarf virus, with protein identity ranging from 88 to 98%. The virus was subsequently transmitted to a CBD-resistant cotton variety using Aphis gossypii and symptoms were successfully reproduced. To study the persistence of the virus, we analyzed symptomatic plants from CBD-resistant varieties from different cotton-growing fields between 2013 and 2015 and showed the presence of the same virus strain. In addition, a constructed full-length infectious cDNA clone from the virus caused disease symptoms in systemic leaves of CBD-resistant cotton plants. Altogether, the new leafroll disease in CBD-resistant cotton plants is caused by an atypical cotton leafroll dwarf virus.
