Abstract:

Revised 06/2015; Originally published 02/2001<br>2 pp.<br>After stand establishment, the next critical stage in the development of a cotton crop is the initiation of the first squares, or floral buds, which could develop into the plants’ first boll. This is an important step for a cotton crop and one which is usually followed closely by the attentive farmer.

Abstract:

Summaries of cotton crop phenology, as a function of heat units (HU, 86/55°F limits) have been developed across a wide range of production conditions in Arizona. Optimum ranges in HU accumulations since January 1 are used to describe planting dates to maintain optimum yield potentials with full season varieties. Basic events such as the occurrence of pinhead squares, squares that are susceptible to pink bollworm, and first bloom are described in terms of HU accumulations since planting. Also, the expected ranges of HU's accumulated since planting that are required to accomplish crop cut -out a

Abstract:

10 pp.<br>Upland cotton is vulnerable to heat stress during the summer monsoon season in the low desert of Arizona. The primary impact of heat stress is a reduction in fruit retention which can reduce overall lint yields, delay crop maturity and reduce lint quality. This bulletin provides a general overview of cotton heat stress as it pertains to Arizona production systems.

Abstract:

Trehalulose and melezitose produced by Bemisia argentifolii Bellows and Perring and thermodetector counts in cotton lint increased with increasing numbers of days of exposure of open cotton bolls in infested cotton plots. Thermodetector counts were significantly correlated to amounts of trehalulose and melezitose. Rainfall of 0.5 inch reduced trehalulose and melezitose in cotton lint within 5 h following the rain. The results suggest dissolution of the sugars followed by runoff as opposed to microbial degradation.

Abstract:

Sustainable geopolymer composites reinforced with natural cotton fibres have been developed and their mechanical and durability properties are evaluated in this research. Results showed that the mechanical properties (flexural strength, flexural modulus, fracture toughness, compressive strength, impact strength and hardness) of woven cotton fabric-reinforced geopolymer composites were superior to those of geopolymer composites with short cotton fibres. Exposure to water and elevated temperatures (200 to 1000°C) severely reduced the mechanical properties of the composites.

Abstract:

A field study was initiated in the summer of 1993 to investigate the effect of increased night temperatures on cotton reproductive development. DPL 5415 was planted on May 10.

The two temperature treatments were initiated at first bloom and treatments terminated after 6 weeks.

Abstract:

Settler farmers in Swaziland failed in their attempt to confine cotton production to their estates partly because of capital limitations. During the First World War some Swazi had fought hard to legitimise cotton production by them, and this became manifest in the 1920s and 1930s when early Swazi cotton growing entrepreneurs emerged, particularly notable being the role of Swazi pastors of religion. But since the cotton price was low, Swazi advances were limited until the late 1950s when some growers made relatively great strides in cotton cultivation especially in the south eastern area. Exter

Abstract:

Weather conditions leading to the development of southwestern rust on cotton were evaluated at 3 locations in southeastern Arizona. Rust appeared following an extended period of wet, humid weather. In excess of 16 hours of wet canopy/high humidity conditions were observed on two consecutive days between 5 and 7 days prior to the appearance of rust. Temperatures during the wet canopy/high humidity periods were moderate, ranging from 65 F to 76 F. Afternoon rain showers initiated these extended periods of wet canopy /high humidity conditions.

Abstract:

Hormone analyses were conducted to determine why large squares seldom shed while young bolls do. Large squares contained five times as much free auxin as flowers, and they contained 16 times as much bound auxin. The high auxin content of large squares is probably a major reason that they almost never shed unless injured (for example, by insects). Free and bound auxin both decreased to very low levels at flowering and remained low for four days thereafter. This low concentration of auxin at, and just after, flowering is probably a major reason that bolls are likely to shed during the week after

Abstract:

A stain-clearing method, which facilitated the analysis of large numbers of ovules, was developed using methyl salicylate (MS) and azure C, and used with real-time video imaging and image capture. The ability to modulate contrast and illumination intensity using video made it feasible to reduce stain intensity and thus light interference from the specimen. Samples stained and cleared were used as whole mounts which allowed the specimen to be oriented for precise analysis. Of 440 semigamous zygotes examined 439 had one egg and one sperm nucleus resulting from syngamy without karyogamy indicatin

Abstract:

The agriculture and manufacturing sectors have been identified and prioritized by the Zambian government as sectors that could contribute significantly to poverty reduction through industrialization and creation of employment. The cotton textile industry is one such industry that cuts across the two sectors. This research paper focuses on the cotton textile industry in Zambia, with specific emphasis on Mulungushi Textiles Limited that was reopened by the Republican President, His Excellency, Mr. Edgar Chagwa Lungu in August 2016 after having been closed for about a decade. To this end, the mai

Abstract:

The fibre properties of cotton, which vary widely according to genetic and environmental conditions, determine its price and textile processing performance and product quality. It is therefore hardly surprising that cotton fibre properties are routinely measured for trading and quality control purposes, with a great deal of research having been, and still being, devoted towards developing instruments which enable the various fibre properties to be measured rapidly and accurately. In many cases, it is also necessary to be able to measure properties of cotton fibres when they have already been c

Abstract:

A series of experiments was conducted to evaluate the responses of S. littoralis (Boisd) to seven plants species. Probable factors responsible for the preference for some of the food plants were determined. In multiple-choice preference tests, both 1st and 4th instar larvae preferred dicotyledonous to monocotyledonous plants. First instar larvae rejected millet. In two-choice tests using maize, millet and sorghum, the larvae always preferred maize. Studies on growth and development of the larvae on the food plants were carried out. The larvae failed to develop to the pupal stage on millet. Gro

It is mainly based upon a field study conducted in Eregli, an industrial town in Central Anatolia, and evaluates workers&rsquo<br>attitudes towards the effects of privatization on their lives. For that purpose, firstly, social development paradigm is highlighted since its current premise is the necessity of privatization<br>secondly, Turkish Experience of the State Economic Enterprises is taken into consideration<br>and lastly, providing a case study on the privatization of S&uuml<br>merbank Eregl
