introduction crop productivity is highly constrained by water and nitrogen limitations in many areas of the world (kalra et al., 2007). therefore, there is a need to investigate more on nitrogen and water management to achieve higher production as well as quality. irrigated sugar beet in the cropping systems of khorasan province in northeastern of iran accounts for about 34% of the land area un...

In sugar beet (Beta vulgaris altissima), bolting tolerance is an essential agronomic trait reflecting the bolting response of genotypes after vernalization. Genes involved in induction of sugar beet bolting have now been identified, and evidence suggests that epigenetic factors are involved in their control. Indeed, the time course and amplitude of DNA methylation variations in the shoot apical...

abstract the purpose of this study is investigating factors affect on probability of willingness to pay sugar beet farmers for taking of agricultural extension services. logit model was used for cross sectional data in 2009 between 150 sugar beet farmers that were selected by random sampling in the city of mashhad. in addition, tobit model was used to analyse factors affecting on willingness to...

in order to study the possibility of control of heterodera schachtii  in sugarbeet fields through integration of rotation with non- host crops and resistant catch crops and their effects on quantitative and qualitative traits of sugarbeet, this study was started from 2002 for three years in esfahan province. the experiments were carried out in a randomized complete block design with eight treat...

the objective of the present experiment was to study the root mass and sugar losses of sugar beet during the storing beets in two methods of on-farm storage. a factorial split plot experiment with nine replications based on a completely randomized design was conducted during 2005 in the experimental fields of sugar beet seed institute (sbsi) of iran, in karaj. combination of two harvest dates (...

Powdery mildew of sugar beet, a disease of major economic significance, was first described at the beginning of the 20th century, and since then there has been some confusion over the correct taxonomic identity of the causal agent. In Europe, the fungus was initially classified as the novel species Microsphaera betae, later re-named Erysiphe betae, whilst in America it was identified as E. poly...

objective: many agronomic practices may need to be adjusted to maximize yield and quality of sugar beet. thus agronomic package must be always modified. this sutdy was laid out for evaluation of changes in carbohydrates and sugar yield in sugar beet (beta vulgaris l.) under different biofertilizers and irrigation closed time at dorud region of iran, during 2013. methods: the experimental design...

the effects of above and below-ground competition between chenopodium album and sugar beet (beta vulgaris) on growth, yield and quality of two sugar beet cultivars of morphologically contrasting growth habit have been investigated a factorial experiment (2 × 4) under glass-house conditions in a randomised complete block design with three replications was done. c. album and two sugar beet cultiv...

Abstract Pectin from two different plant sources: apple and sugar beet was studied. Apple pectinwas modified by chemical treatments such as: acid, alkali and ammonia, so as to obtain an ester levelequal to or less than 50 %, which is described as low methoxyl (LM) pectin. LM pectin form gelswith significant characteristic. In this study, de-esterification of apple pectin with acid treatmentresu...

sugar beet pulp is one of the sugar industries by-products which can be used for cellulase enzyme production, enzymatic saccharification, and alcohol production due to its high percentage of lingo-cellulosic content. trichoderma spp. is an important fungus that produces a wide range of cellulytic enzymes. in this study, cellulase enzyme was produced by placing sugar beet pulp in trichoderma fer...
