Invasive species are not new phenomena in U.S. agriculture, as illustrated by these 1920s lyrics from the Boll Weevil folksong. The boll weevil entered the United States via Mexico in the 1890s, and by the 1920s, this pest had spread to all cotton producing states, wiping out tens of thousands of acres of cotton, costing billions of dollars, and literally driving thousands of farmers off the la...

In the recent years, increasing labour cost and shortage of being major constraints to follow manual harvesting in cotton staggered manner. Further, it is very expensive farmers would like increasingly opt for mechanical harvesting. this context, suggested that research should focus reduce cultivation substantially by promoting use synchronized maturity defoliants encourage agriculture, are use...

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 ...

irrigation water and nitrogen fertilizer are two important factors in increasing the yield and yield components of cotton. in order to evaluate effects of irrigation methods, various levels of water and nitrogen fertilizer on yield and yield components of cotton were studied at hashemabad cotton research station of gorgan in 2008. the experiment was conducted in split-split plots design with th...

the objective of deficit irrigation is to increase water use efficiency by reducing of water quantity or wave off further irrigations that have not necessary. cotton plant is sensitive to irrigation timing and quantity through different growth stages. the field trail was conducted at hashemabad cotton research station (gorgan) to determine water consumption and cotton sensitivity to deficit irr...

Klebsiella pneumoniae (associated with bacterial pneumonia) was previously isolated from Nezara viridula, a significant vector of cotton boll-rot pathogens. We provide the first annotated genome sequence of the cotton opportunistic strain K. pneumoniae 5-1. This data provides guidance to study the bases of cotton pathogenesis by bacteria associated with vectors.
