Fine-tuned and coordinated regulation of transport, metabolism and redox homeostasis allows plants to acclimate to osmotic and ionic stress caused by high salinity. Sugar beet is a highly salt tolerant crop plant and is therefore an interesting model to study sodium chloride (NaCl) acclimation in crops. Sugar beet plants were subjected to a final level of 300 mM NaCl for up to 14 d in hydroponi...

The beet armyworm, Spodoptera exigua, is one of the most important pests of sugar beet in Iran. The aim of this study was to determine the effect of water and nitrogen treatments of sugar beet planton developmental time and fecundity life table parameters of the pest. An experiment was carried out under laboratory conditions (25±2oC, 70±5% R.H. and 12L: 12D) on larvae reared...

The species Beta vulgaris encompasses wild and cultivated members with a broad range of phenological development. The annual life cycle is commonly found in sea beets (ssp. maritima) from Mediterranean environments which germinate, bolt, and flower within one season under long day conditions. Biennials such as the cultivated sugar beet (B. vulgaris ssp. vulgaris) as well as sea beets from north...

During the 19th century the cultivation of grass and root crops for the production of raw sugars was associated with some of the most important developments in the international economy. The burgeoning demand for cheap foodstuffs from the industrial centres of Western Europe and the United States led to an enormous increase in demand for cheap sugm along with other wicultural and industrial com...

introduction crop productivity is highly constrained by water and nitrogen limitations in many areas of the world (kalra et al., 2007). therefore, there is a need to investigate more on nitrogen and water management to achieve higher production as well as quality. irrigated sugar beet in the cropping systems of khorasan province in northeastern of iran accounts for about 34% of the land area un...

American sugar beet farmers produce half of our domestic refined sugar valued at over $3 billion per year (APHIS, 2010). The U.S. District Court for the Northern District of California (CA District Court) will soon determine whether U.S. farmers can continue to grow genetically modified (GM) sugar beet (Beta vulgaris ssp vulgaris var altissima) in the case of Center for Food Safety v. Vilsack (...
