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...

abstract the aim of this study was to selecting the suitable model for forecast land, production and price of sugar beet in iran. for this purpose, models applied to forecast are arima, single and double exponential smoothing, harmonic, artificial neural network and arch for period 1993-2008. results of durbin-watson tests, land, production and price of sugar beet series were found non stochast...

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 (...

in order to determine the effects of water deficit at different growth stages of sugar beet and optimal usage of water on quality and quantity characters of sugar beet, a factorial experiment based on randomized complete block design was conducted with 13 treatments and four replications in 2000 and 2001 in agricultural research center of hamadan. for the first factor, irrigation withheld in th...

Beta vulgaris genus comprises wild and cultivated subspecies. The “maritima” subspecies is formed by wild or weedy accessions, well adapted to low-water potential environments; it was previously shown that B. vulgaris ssp. maritima has mechanisms of osmotic adjustment more effective than the cultivated B. vulgaris ssp. vulgaris. The response to a progressive lowering of soil potential was compa...

Thirty-six Merino lambs (8 to 9 wk of age, and 15.3 ± 0.13 kg of initial BW) 1 were used to evaluate the effects of the inclusion of 120 g sugar beet pulp (replacing 2 barley) and of the addition of 20 g sodium bicarbonate per kg concentrate on feed 3 intake, digestibility, animal performance and carcass characteristics in fattening lambs. 4 Animals were housed individually and fed barley straw...
