the purpose of this study is determining the factors affecting timeliness of machine operation at different stages of sugar beet production. farm-level data were collected from a sample of 227 sugar beet farmer located in three major districts of farsprovince ofiran: eghleed, marvdasht and fasa, selected by a random sampling method during 2006. for this purpose, the probit model was used. the r...

BACKGROUND Intermediates from processing sugar beets are considered an attractive feedstock for ethanol fermentation due to their high fermentable sugar content. In particular, medium prepared from raw sugar beet juice seems to be suitable for use in fermentation processes, but it is microbiologically unstable and requires sterilization. RESULTS This study investigates the effect of ozone tre...

Climate is one of the most important factors that influence the quality and quantity of crops. Understanding the natural features of any region, especially about the climate, can play a major role in making plans and land use planning.

Beet necrotic yellow vein virus (BNYVV) is a member of the genus Benyvirus (21,22) and causes the disease known as rhizomania. It often is reported to be the most important sugar beet (Beta vulgaris L.) virus (17). BNYVV is transmitted by the plasmodiophorid, Polymyxa betae Keskin (1,2,6). In the United States, the virus first was identified in California in 1984 (5) but now occurs in every maj...

for determination of water stress effects in different growth stages of sugar beet and optimum water usage on quantity and quality of sugar beet, this study was performed using randomized complete blocks design in factorial experiment with 12 treatments and 4 replications from 1999 to 2001 in agricultural research center of hamadan. the first factor was non-irrigation in 3 stages of growth (s1-...

ethanol is a clean and renewable energy source. the necessity of ethanol usage, instead of fossil fuels or mixed with them, in order to reduce environmental pollution resulted in increase of ethanol production from 50 million m-3  in 2007 to 85 million  m-3 in 2012. the present study aimed to compare the cost of bio-ethanol production from sugar beet with other agricultural crops, and also econ...
