beet yellows virus (byv) belongs to the genus closterovirus, closteroviridae family, is one the most important viruses of sugar beet worldwide. in order to identify and characterize some molecular aspects of the byv, a total of 75 symptomatic leaf samples of sugar beet were collected from sugar beet field of west azarbayjan, hamedan and kermanshah provinces, iran. leaves showing general yellowi...

In Europe, the framework for sugar beet (Beta vulgaris L.) production was subject to considerable changes and for the future it is expected that sugar beet cultivation might concentrate around the sugar factories for economic reasons. Based on data from a national sugar beet farmers' survey and multi-year crop rotation trials, the effects of cropping interval (number of years in between two sub...

to determine the effects of different irrigation and salinity levels on qualitative and quantitative yield of sugar beet, an experiment was conducted for two years (2006-07)at torogh agricultural research center, mashhad, iran, using two sprinkler systems. each of the two irrigation systems was connected to two water sources with 1 and 6 ds/m salinity. irrigation was performed via two sprinkler...

Concerns have been raised in Europe about the efficiency, sustainability, and environmental impact of the first genetically modified crops. The committees and regulators in charge of approving procedures have encouraged a field trial approach for safety assessment studies under current agronomic conditions. We describe the gene flow from sugar beet (Beta vulgaris L.) in a multi-year and multi-c...

sugar, which can be extracted from sugar cane and sugar beet, is one of the most important ingredients of food. conducting more research to increase the extraction efficiency of sugar is necessary due to high production of sugar beet and its numerous processing units in northern khorasan province. in this research, the effect of temperature, time and the frequency of ultrasonic waves on mechani...

Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

in most of the sugar beet cultivated areas including kermanshah, iran, late season irrigation is cut- off earlier than usual which causes drought stress in the crop. since root yield still increses in sept. and oct. these areas, withholding irrigation in this period reduce root yield and quality of sugar beet. for this reason, an experimente was conducted during 2004- 2005 based on split plot d...

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...

The Farm Scale Evaluations of genetically modified herbicide-tolerant crops (GMHT) were conducted in the UK from 2000 to 2002 on beet (sugar and fodder), spring oilseed rape and forage maize. The management of the crops studied is described and compared with current conventional commercial practice. The distribution of field sites adequately represented the areas currently growing these crops, ...

In this study, a total of 299 grain samples of wheat were collected from four production regions: the maize, sugar beet, potato and feed sectors of Slovakia. The samples were analyzed for deoxynivalenol (DON) content by using an enzyme-linked immunosorbent assay Ridascreen® Fast DON. Analysis of variance revealed a significant difference between years in DON contents (p < 0.027). The occurrence...
