Abstract

The main objective of the present investigation is to evaluate the spinning efficiency for different commercial cotton varieties in addition to a new promising of Egyptian cotton using two spinning systems i.e., ring and compact spinning. Two Egyptian cotton categories were tested in this study, ElS & LS categories. The first one is an Egyptian cotton genotypes named Giza 88, Giza 92 belong to the category of Extra-long staple varieties in addition to a new promising variety Giza 93 which also belong to the same category . The second is the long staple commercial genotypes named Giza 86 and new promising cross namely Giza 86X10229 (New cross). The Egyptian commercial cotton varieties and promising crosses were spun into two different spinning systems (compact and conventional ring spinning) and four different yarn counts (60’s, 80’s, 100’s, 120’s and 140’s on the same twist multiplier (4.2).

The results obtained that compact spinning system offers better utilization of fibers and increases the spinability of the Egyptian cotton. In addition, there is a high correlation between the spinning system and yarn count on its physical and mechanical properties.

The new promising cross Giza 93 recorded the highest values of Single yarn strength (g/tex), elongation (%), yarn evenness (C.V. %) and Lea Count Strength Product which gained by the compact spinning system at yarn count 80’S compared with the cotton variety Giza 88 at the same yarn count and spinning system. However, the highest imperfections yarn values (thin places, thick places and neps count /1000 m) were positively associated by the cotton variety Giza 88 which spun at the 140’S yarn count and the ring spinning system.

The second experiment indicated that the best yarn quality for strength (g/tex), elongation (%), yarn evenness (C.V. %) and Lea Count Strength Product were recorded by compact spinning system of the cotton new cross namely Giza 86X10229 when spun at 40’S yarn count. On the other hand, the lowest values of the same traits were possessed by the cotton variety Giza 86. Meanwhile, the cotton variety Giza 86 supposed the highest imperfections yarn values (thin places, thick places and neps count /1000 m) with ring spinning system and 100’S yarn count.

Abstract

Cotton is the most important strategic crops in Egypt and plays a major role in the Egyptian national economy, because it is an important source of raw material in cotton textile industry as well as being a source for the production of cottonseed oil and used in animal feeding. Cotton stalks produced as a byproduct of post-harvest with large quantities of thousands of tons annually, causing many problems such as: 1. the farmer storing it on the roofs of the houses, causing fires when the wind coming, 2. or burning it causing significant environmental problems, which lead to spread of many human diseases, 3. on the other hand, cotton stalks contain eggs and larvae of pink boll worm, which remain dormant until cultivating the next crop, causing serious damage on the cotton crop.

Globally perception of the plant wastes during the past decades was changed, the thinking is shifting from search for ways to control it and minimize its damage to use it as source of income. Nowadays control of the plant waste does by using different treatment types such as biological or chemical or physical methods.

In Egypt the common way to get rid of cotton stalks are by burning it, which causing environmental problems. So this article  will show  how nowadays in Egypt thought regarding transforming it to some useful and economical products such as organic fertilizer (compost) , animal feed (silage) , Wood , cellulose derivatives and Charcoal, …..etc.

Abstract

As from late Eighties of the last century, what’s called technical equity markets exist as spread of internet system in which make it possible that both supply and demand for goods and services are available within 24 hours a day. But so far a little attention has been given to improving the accuracy of price determination resulting from demand for immediacy and for too much importance has been attached to the supply of immediacy ( the ability to trade at any time in the continues market ). Unfortunately, participants pay price to trade whenever they wish during trading section the components include the bid-ask spread, market impact and commissions. In addition the temporal fragmental of orders in one continuous market makes the market more opaque.

Thus for the assumption that participants demand transactional immediacy has gone practically unquestionable would some asset managers choose not paying the price of immediacy of the truly understood the cost of the service and if they had an alternative . Immediacy clearly important to a participant seeking to trade on information that has not yet been reflected in market prices and many participants most notably the mutual funds, do have to trade certain amount each day because of deposits redemptions or their cash flow needs. This does not mean however that they must be able to trade at any given  moment in the day. It  is conceivable  that  the provision  of immediacy because it temporally fragments orders actually makes it more difficult for these participants to “get the job done” at a reasonable cost by the end of the day.

On this presentation concentration will be devoted to the following topics

  • Transparency
  • Price Discovery
  • Taking decisions for immediacy demand
  • Consideration of the order flow
  • Market structure

Abstract

Ginning is the mechanical process for separating cotton into its constituents namely lint (Cotton Fibre) and Cotton Seed. The Seed Cotton that comes from the field has to be subjected to various treatments in the ginning factories depending upon its inherent characteristics such as trash contents, moisture contents, length of the fibre, variety of seed i.e. fuzzy or black, method of seed cotton transportation, storage practices, handling practices inside the ginning factories and finally subjected to ginning process for separation of fibre and seed before packing into bales etc. Ideally the quality of the constituents i.e. cotton fibre and cotton seed before ginning and after ginning must be more or less same however it is

seen that substantial damage is caused to quality parameters during processes in the ginning factories. The selection of cotton for spinning is made on the basis of fibre quality and any damage in the same during the process of ginning reduces the value of the fibre and results in lowering down of value in total textile value chain.

The development of high speed spinning and weaving machinery has necessitated requirement of better cotton fibre parameters and any damage in quality caused while ginning cannot be rectified later and the defect is carried forward to yarn and fabrics during spinning and weaving process.

The economics of ginning operation is greatly affected by the damage in the quality of the constituents i.e. cotton fibre and cotton seed and lower realization due to same affects down the line to the farmer / grower as the pressure of the lower realization by ginners results in lower price for seed cotton being paid to him.

The economics of ginning operation depends upon the proper selection of ginning technology suitable for various characteristics of the seed cotton to optimize the quality parameters and operational costs, thus the selection of suitable ginning technology is of paramount importance.

Abstract

The introduction of TMC and TUF by Govt. of India from year 2000 made great impact on modernization of ginning sector in India and even after completion of TMC in year 2010 it has created a trend of automated and modernized ginning factories in India hence majority of new ginning factories being established even after year 2010 in India are following the guidelines of TMC. This has resulted in significant reduction of trash and contamination in Indian cotton. The Indian cotton has got wide acceptance across the globe on quality parameters and India has achieved the status of second largest exporter of cotton in the world.

The journey of modernization of various operations in a ginning

& pressing factory is being continued to further improve the quality and cost efficiency as well as ease of operations for ginning & pressing factories and many advances have taken place in the past few years to improve the processing of this unique crop, each component of which is having multiple uses similar to items like coconut where each component adds to value. Continued journey of advances is day by day improving the areas remaining to be addressed for the cotton processing sector in most beneficial manner.

The Goals:

The full potential of the cotton crop by optimizing the processing parameters and to make its fullest and best use will be achieved only when following goals are achieved:

  1. The cotton fibre will be ginned in a  way  that  it  retains best natural fibre parameters e. maximum length,  natural  luster, and other natural parameters as they are available on the cotton boll when it is grown on plant in the field.
  2. To fully utilize the various components of seed cotton e. cotton lint, cotton seed, hull, kernel, and oil.

To fully utilize the cotton stalk etc. to make various items such as wood pallets, particle boards, biogas, energy generation & compost making.

Abstract

Verticillium wilt of cotton is a destructive disease that causes considerable yield losses on the crop. There is no effective method for controlling Verticillium wilt of cotton that is one of the world’s most devastating diseases except breeding resistant varieties. Due to environmental concerns of chemicals used in the control of this disease in which using antagonistic bacteria as a biocontrol agent to suppress the disease is very important. In addition, bacteria converting phosphorus to a form that is useful for the plant can offer an advantage for plant growth and disease resistance. Isolation the bacteria from the soil and use as plant growth regulation are the focus of some research has been going on.

Starting by 2014, this study will continue for 3 years. Starting, soil samples were collected at different vegetative periods of plant from 25 different cotton producing areas (from July to September) and pure strain cultivars were obtained from 650 soil samples. Tests applied to these strains are Hypersensitive Reaction on Tobacco, Levan Formation, Oxidase, Hydrogen Peroxide And Potassium Hydroxide. Resulting of identification tests, isolates that doesn’t have pathogenicity were tested for the ability to convert the phosphorus obtainable for by the plants, resulting of identification tests, isolates that doesn’t have pathogenicity will be used to antimicrobial activity in both greenhouse and in the field trials.

Abstract

Cotton, a major cash crop of Pakistan, is considered as backbone of the national economy. It contributes about 1.4% to GDP and 6.9% of total value addition in agriculture. Pakistan is the fourth largest producer, third largest consumer of cotton and the second largest exporter of cotton yarn in the world. The cotton sowing target proved in data that in Pakistan cotton target increased in cotton sowing areas due to evolved the new cotton high yielding varieties in Pakistan. Cotton crop is mainly grown in Punjab and Sindh provinces in Pakistan, contributing 70 and 29.50 percent in cotton production respectively. During survey in different cotton growing districts of Sindh-Pakistan, mealybug and CLCuV disease infestation was recorded which gave damage quantitatively and qualitatively to cotton growers. Pakistan Central Cotton Committee is working on long extra long staple length cotton varieties and these varieties were tested for checking the performance which will open the doors for farmers and breeders to utilize this material for better economy of Pakistan. Further it is explain that purpose of this paper presenting in 12th Meeting of the Inter-Regional Cooperative Research Network on Cotton for the Mediterranean and Middle East Regions will be held in Sharm El-Sheikh, EGYPT from October 7-9, 2015 to share the problems, strategies to control on the CLCuV, to produce the long extra long staple varieties as produced in Egypt and to share the new technology/developments on cotton in the world.

Abstract

Cotton (G. hirsutum) is a crop of tropical and subtropical regions but despite of this, it is highly sensitive to heat stress. Heat stress during flowering and boll growth period cause shedding of flowers and bolls which cause a significant loss in yield. There is only a little information is available which describes the effect of high temperature on development of fruiting parts in cotton. Therefore an experiment was conducted to assess the effect of heat stress on development of reproductive parts. A two year experiment was laid out in randomized complete block design with four replications and three factors during 2013-15. The factors included four sowing dates (1 April, 1 May, 30 May and 30 June) and three cotton cultivars (IUB-222, IUB-13 and IUB-63). Flowering in early sowing (1 April and 1 May) initiated during high temperatures of June and July and these are taken as heat stressed whereas flowering in late sown (30 May and 30 June) initiated during optimum temperatures of august and September and these were taken as non-stressed. Data was collected for daily mean temperature, days taken to initiation of square development, days taken from square to flower, days taken from flower to boll open, boll retention, boll size, seed weight, seed volume, seed density and seed surface area. The  analysis of variance revealed  that significant (P≥0.05) genotypic and sowing date differences existed for all studied traits and genotype × sowing date interaction was also significant (P≥0.05). The results revealed that heat stress decreased the days taken for initiation of square development, days taken from square to flower and flower to boll open, boll retention, and boll size. Due to reduction in boll retention and boll size there was reduction in the yield. All seed traits seed weight, seed volume, seed density and seed surface area reduced with heat Correlation analysis revealed that mean daily temperature had significant (P≥0.05) negative correlation with all the traits studied. The genotype IUB-63 performed best and was least affected by the heat stress, so proved as heat tolerant genotype. It is conclude from the results that fruit development traits and seed physical traits can be an effective selection criteria for heat stress breeding.
