to determine sugar beet water requirement and the effect of changing the quantity of applied water on some production components, a study was carried out in ekbatan agricultural research station of hamedān, iran in four years (1994-1997) during which optimum water requirement, root and sugar yield, water use efficiency on the basis of root yield, sugar percentage and water use efficiency on the...

monogerm and multigerm seed varieties are used in sugar beet cultivation. singling is inevitable and mechanization almost impossible when multigerm seed varieties are used. for this and for some other reasons, economically sound and fully mechanized cultivation of sugar beet calls for the use of monogerm seed varieties. throughout europe, only monogerm varieties are used in sugar beet productio...

sugar beet is one of the most important crops in khorasan razavi, iran, which plays an important role in the economy of this province. so, it seems to be important to study the efficiency of the crop. to analyze the sugar beet efficiency information, two methods including data envelopment analysis (dea) and stochastic frontier analysis (sfa) methods were used. required data were collected from ...

The influence of salinity on the different polyamine fractions (free, conjugated, and bound) was compared in a natrophilic halophyte (Beta vulgaris L. cv. IC) and a salt sensitive glycophyte (Nicotiana rustica L. cv. Basmas). Low-level salinity (25 mM NaCl) and high salinity (150 and 50 mM NaCl for sugar beet and tobacco, respectively) were supplied in hydroponics. Under low salinity shoot dry ...

The most employed microorganism used for fermentation is Saccharomyces cerevisiae yeast due to its ability to hydrolyze sucrose from cane or beet molasses i...

Previous research of complex-offer auctions designed for deregulated electricity markets finds that offer complexity allows great deal of strategic behavior, which consequently leads to anti-competitive and inefficient outcomes. In these smart markets that employ complex-offer auctions, the sellers submit not only quantities and minimum prices at which they are willing to sell, but also start-u...
