Several studies suggest that the $1.4 billion in government subsidies are encouraging the ethanol program without substantial benefits to the U.S. economy. Large ethanol industries and a few U.S. government agencies, such as the USDA, support the production of ethanol. Corn-farmers receive minimal profits. In the U.S. ethanol system, considerably more energy, including high-grade fossil fuel, i...

In order to study the genetic control of root yield, sugar yield and white sugar yield in tropical beet, the biplot of diallel data was used. 36 hybrids derived from crosses among 9 sugar beet genotypes along with four control treatments were evaluated at Safiabad Agricultural Research Center, Dezful, Iran during 2008-2009 growing season. The experimental design was a triple lattice design with...

ABSTRACT-Several herbicides are registered for selective weed control in sugar beet; however, no single chemical herbicide can control all weeds in beet fields. Frequently, two or more herbicides may have to be combined sequentially or as tank mixed to achieve adequate broad-spectrum weed control. In order to evaluate the effects of some combinations of broadleaf herbicides on sugar beet yield ...

The current study aimed to evaluate the variation in fermentation activity along the distal canine gastrointestinal tract (GIT, Exp. 1). It also aimed to assess fermentation kinetics and end product profiles of 16 dietary fibers for dog foods using canine fecal inoculum (Exp. 2). For Exp. 1, digesta were collected from the distal ileum, proximal colon, transverse colon, and rectum of 3 adult do...

UNLABELLED SUMMARY Taxonomy: There are three members of the genus Polerovirus (family Luteoviridae) that induce yellowing of sugar beet: Beet mild yellowing virus (BMYV), Beet chlorosis virus (BChV) and Beet western yellows virus-USA (BWYV-USA, Fig. 1). Non-beet-infecting isolates of BWYV found particularly within Europe have now been re-named Turnip yellows virus (TuYV). Species-specific antib...

Shortage of irrigation water is the most important limiting factor in sugar beet production, therefore, winter sowing can be a suitable strategy to increase water produvtivity and production of this crop. For this purpose, 11 sugar beet early cultivars were sown in the first half of February and were studied on two different harvest dates (early and late July) at Moghan Agricultural Research St...

Agriculture has been historically one of the main sectors Ukrainian economy. Considered for centuries as a “bread basket Europe”. In recent years Ukraine’s agriculture consistently improving and only part country’s economy to buck recession, but Ukraine is still country with relatively large untapped agricultural potentials. The study concerns production crops in 1992-2020 witch short-term pred...
