Determination of the amount of sugar in sugar beet is usually accomplished by polarimetric method in sugar industry. This method is not accurate due to impurities such as sodium, potassium and amino-nitrogen that are present and might cause some errors in the evaluation of the technical quality of sugar beet. In this research, 7309 samples of sugar beet from two semi- arid county, Isfahan and C...

low water consumption in autumn sugar beet sowing is an important strategy for sugar beet production, especially in arid regions like iran. for the development of a new monogerm triploid hybrid called sharif which is bolting tolerant and suitable for autumn sowing in khuzestan province, a breeding program was started in 1994 and continued for16 years. this program had two stages; the first stag...

in order to investigate the effects of saline waters on some soil characteristics, this experiment was conducted with three irrigation water salinity treatments contains 1.7-3.4, 8-9 and 11-12.5 dsm-1 (low, medium and high salinity) and two irrigation water managements with four replications in a wheat-fallow-sugar beet-safflower rotation. results show that in (1) irrigation management with low...

Growth response of sugar beet plants to drought stress applied at different growth stages has been investigated. Cessation of watering imposed moderate water stress and resulted in the reduction of the relative water content of young and old leaves maximally by 6%. However, water content in taproot was more drastically decreased than in the shoot. Water withholding reduced dry ma�er accumulatio...

Strausbaugh, C. A., Wenninger, E. J., and Eujayl, I. A. 2014. Control of curly top in sugar beet with seed and foliar insecticides. Plant Dis. 98:10751080. Curly top in sugar beet is a serious problem that is caused by Beet curly top virus and other closely related species and transmitted by the beet leafhopper. In order to find a means of reducing curly top in sugar beet, 15 combinations of in...

Beet necrotic yellow vein virus is the etiological agent of one of the most devastating sugar beet viral diseases: rhizomania. This review describes the molecular biology of the rhizomania disease, the functions of the BNYVV encoded proteins, the consequences of their expression as well as the biology of the BNYVV vector, Polymyxa betae. Root proliferation is an important part of the well-known...

Today climate change is one of the most important human concerns This fact affected human life in different ways .  one of the most important impacts of climate change is on crops yield so that change in temperature  regime  particularly maximum and minimum  temperatures  is noticeably change plants production . in this research , is considered to  impact of climate change on water requirement ...

resistance of 16 sugar beet cultivars to cercospora leaf spot was evaluated in ghaemshahr region. the experiment was conducted in a complete block design with six replications and disease severity of cultivars was measured two times. as a winter crop the root yield of cultivars and their disease severity compared under natural cercospora infection in dezfoul area in a complete block design with...

on of the most important of sugar beets quality is amount of sodium and potassium, because this compounds are strongly molassogenic and reduction of yield. so , attention on reasons that change this compound in sugar beets and consequently in produced juice are very important. in this study, effect of size of sugar beet (obtained from different areas) on changes of sodium and potassium are inve...
