the main objective of this study is to investigate the comparative advantage for sugar beet production in iran. sugar beet is one of the main crops which is considered as an important resource for energy supply. the importance of sugar beet (as a sugar source) in iranian household food basket, price fluctuation and consumers' demand for sugar beet, social profitability and the impact of go...

SUBEMOpo (SUgar BEet MOdel potential production) is a mechanistic simulation model to simulate sugar beet growth and sugar accumulation for potential production conditions. Under those conditions sugar beet growth and sugar accumulation are entirely controlled by the prevailing weather (radiation, temperature) and by the crop characteristics (plant density). The only site characteristic require...

The decision of whether to release transgenic crops in the EU is one subject to flexibility, uncertainty and irreversibility. We analyse the case of herbicide-tolerant sugar beet and estimate the maximum irreversible environmental cost that can be tolerated for this technology from a benefit–cost perspective. Among Member States, these costs range from an annual € 50 to € 212 per hectare plante...

Male gametogenesis in plants can be impaired by an incompatibility between nuclear and mitochondrial genomes, termed cytoplasmic male sterility (CMS). A sterilizing factor resides in mitochondria, whereas a nuclear factor, Restorer-of-fertility (Rf), restores male fertility. Although a majority of plant Rf genes are thought to encode a family of RNA-binding proteins called pentatrico-peptide re...

sugar beet is an important crop from the point of production and consumption. in this case, fars province is one of the largest producers iniran. the purpose of this study was to determine the effective factors on sugar beet supply. accordingly, time series information of the crop was collected from 1990 to 2004 infarsprovince and were analyzed through nerlove partially adjustment model that is...

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. Sugar beet, is one of the major industrial plants, that in addition to producing one of the most fundamental basic needs of society, namely sugar, it can have ot...

to evaluate yield and productivity indices of maize and sugar beet intercropping with different planting ratios, a field experiment was conducted in randomized complete block design with three replication at hamedan province in nahavand, in 2013. the planting ratios were 100:0, 75:25, 50:50, 25:75 and 0:100 (maiz: sugar beet) using replacement method. results showed that intercropping had signi...

___________________________________________________________________________________________ Abstract In commercial ethanol production producers often use sugarcane or sugar beet molasses as raw material due to their abundance and low costs. The most employed microorganism used for fermentation is Saccharomyces cerevisiae yeast due to its ability to hydrolyze sucrose from cane or beet molasses i...

the sugar beet weevil, lixus incanescens boh., is an important insect pest of sugar beet, beta vulgaris l., in razavi khorasan province. in this research, population densities of the sugar beet weevil eggs and larvae were evaluated on plants of six sugar beet cultivars including ardabili, aras, persia, flores, laetitia and rosire in an experimental field in 2011 and 2012. also, the percentage o...
