regard to increasing demand for organic agricultural products, awareness of costs and profitability of organic products can help to decision planners of agricultural sector, and particularly farmers. this study has tried to calculate cost and profitability of cotton product in two different conventional and organic ways (procedure) of production using 253 cross-sectional data from khorasan raza...

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...

Cotton (Gossypium spp.) is the unique, most important natural fiber crop in the world that brings significant economic income, with an annual average ranging from $27 – 29 billion worldwide from lint fiber production (Campbell et al., 2010). The worldwide economic impact of the cotton industry is estimated at ~$500 billion/yr with an annual utilization of ~115-million bales or ~27-million metri...

background: cotton is the main agricultural export product in benin. cotton dust is thus present in the air during the handling and processing of cotton. this dust contains a mixture of substances including ground up plant matter, fibres, bacteria, fungi, soil, pesticides, noncotton matter, and other contaminants. while cotton processing is decreasing in industrialized countries, it is increasi...

cotton (gossypium hirsutum l. cv. varamin ) an important industrial crop of iran, is grown in 300,000 ha, with an average seed -cotton yield of 1750 kg.ha-1. the main obstacle in the way of increasing average cotton yield is imbalanced fertilizer use. along with urea and triple super phosphate, cotton growers also need k, mg, zn, fe, mn, cu, and b, so these elements’ critical levels should ...

OBJECTIVE To microbiologically evaluate the efficacy of cotton and polytetrafluoroethylene (PTFE) tape used as spacer materials. METHOD AND MATERIALS Twenty-six extracted human molars were restored using either cotton or PTFE tape as spacers under a standardized provisional restorative material (Cavit). The teeth were incubated for 7 days in a culture of Streptococcus gordonii or in liquid me...

This paper compares the profitability and cost of production of irrigated Roundup Ready cotton varieties and conventional cotton varieties grown under crop share rental agreements in the Texas High Plains Region for 1998. The Standardized Performance Analysis (SPA) program was used to analyze 25 sub-enterprises for each variety type from six producers selected from the regional SPA database for...

1. The course of typhus infection in cotton rats has been described, and a relationship between the dose administered and the time of death has been demonstrated. 2. Rather incomplete pathological studies indicated that typhus in the cotton rat is an acute infection primarily involving mesothelial tissue, and tissues of mesothelial origin. Depending somewhat upon the route of infection, rickett...

An increasing area of transgenic Bacillus thuringiensis (Bt) cotton is being planted in saline-alkaline soil in China. The Bt protein level in transgenic cotton plants and its control efficiency can be affected by abiotic stress, including high temperature, water deficiency and other factors. However, how soil salinity affects the expression of Bt protein, thus influencing the control efficienc...

Several new developments are likely to occur in the cotton industry during the next decade. Obviously, the impacts of emerging technologies will vary among different regions of the world. However, any new development will likely impact most other cotton-growing areas. To gain a broader perspective, I have consulted experts in various disciplines for assistance. I will summarize my perspectives ...
