cover type of on–farm storages has an important role in reducing the freezing damage and respiration of beet roots in the pile. this experiment was conducted in 2006 in karaj region in order to evaluate the effects of cover types of storage on the mass and sugar losses of both topped and untopped beets. the experimental design was a split plot factorial in rcbd with three replications. the main...

Michael G. Oliva, Ph.D. Professor Department of Civil and Environmental Engineering University of Wisconsin–Madison Madison, Wisconsin The in-plane fl exibility of untopped precast concrete double-tee diaphragms is often ignored in current design practice. The performance of parking structures during earthquakes and subsequent research studies have shown, however, that in-plane fl exibility of ...

Gene flow is a crucial parameter that can affect the organization of genetic diversity in plant species. It has important implications in terms of conservation of genetic resources and of gene exchanges between crop to wild relatives and within crop species complex. In the Beta vulgaris complex, hybridization between crop and wild beets in seed production areas is well documented and the role o...

The amount of wheat and corn produced in excess will be sold at prices of $ 170 per ton for wheat and $ 150 per ton for corn. For sugar beets there is a quota on production which is 6000 T for the farmer. Any amount of sugar beets up to the quota can be sold at $ 36 per ton, the amount in excess of the quota is limited to $ 10 per ton. We denote by w1 and w2 the amount in tons of wheat resp. co...

Reproductive traits are key parameters for the evolution of invasiveness in weedy crop-wild hybrids. In Beta vulgaris, cultivated beets hybridize with their wild relatives in the seed production areas, giving rise to crop-wild hybrid weed beets. We investigated the genetic structure, the variation in first-year flowering and the variation in mating system among weed beet populations occurring w...

Commercial sugarbeet yields range between 50 and 100 t clean beets/ha, with sugar concentrations of 17 to 18% on fresh weight (8 to 18 t sugar/ha; Milford, 2006). For 2010, beet yields in the U.S. averaged 62.2 t/ha. However, in the Imperial Valley (predominant cattle feeding region for the state of California), clean beet yields averaged 98.8 t/ha (USDA, 2010); 9 Imperial Valley beet growers t...

Sugar Beet Nematode (SBN), Heterodera schachtii, is one of the most destructive pests of sugar beets worldwide. It is present in all sugar beet growing areas of Wyoming and is particularly severe in fields located in close proximity to processing plants where sugar beets have been grown the longest. This soilborne, parasitic nematode attacks and destroys the small feeder roots of sugar beet pla...

Beta vulgaris L. (sugar beet, table beet, mangel) is subject to a disease known as blackroot. Buchholtz and Meredith (1944:488) refer to the condition as tiprot, and earlier, Murphy (1927) called it rootburn of beets. Both Byford and Prince (1976) and W. C. Moore (1959) discussed the disease as “black leg.” In 1949(b) Ernould demonstrated that blackroot was not the same pathological condition a...
