introduction: weed competition is one of the major factors which limit sugar beet production in the world. weed – crop interactions are based on competition for water, nutrients and light and allelopathic effects may also play a small role. in sugar beet weed interference, all these factors are important too, but the light is of prime importance. due to the fact that a lot of weeds can grow abo...

lepidoteran pests of sugar beet (beta vulgaris l.) cause a severe yield reduction in the most sugar beet growing areas of the world as well as in iran. due to limited genetic resources of resistance to insect pest and polygenic inhertance, improvement of pest resistance in beet by conventional breeding is a difficult task. biotechnological enhancement by introducing insect resistance genes such...

In order to evaluate the effect of biofertilizers (nitroxin and phosphate barvar2), vermicompost and chemical fertilizers on the quantity and quality traits of sugar beet (Beta vulgaris L.), an experiment was conducted in randomized complete block design (RCBD) with 13 treatments and three replications at Agricultural and Natural Resources Research Station of Miandoab, Iran in 2015. The treatme...

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...

The thermostable enzyme systems produced by the thermophilic ascomycete fungus Talaromyces emersonii cultivated on various carbon sources were investigated for the production of high value products from sugar beet. A broad range of enzymatic activities relevant to cellulose, hemicellulose, and pectin hydrolysis were identified in T. emersonii culture filtrates. In hydrolysis experiments conduct...

Stenotrophomonas maltophilia W81 can protect sugar beet against PYTHIUM:-mediated damping-off disease through the production of an extracellular protease. Here, the proteolytic enzyme of W81 was purified by anion-exchange chromatography and characterized as a serine protease. The purified enzyme was fungicidal against PYTHIUM: ultimum in vitro. Its synthesis was inducible by casein in W81, and ...

The use of sugar beet in anaerobic digestion (AD) during biogas production can lead to process upsets such as excessive foaming in fermenters. In the present study, foam formation in sugar beet-fed digestates was studied in foaming tests. The increasing disintegration grade of sugar beet was observed to have a promoting effect on foaming in the digestate but did not affect the biogas yield. Che...

BACKGROUND In 2006, the European Union (EU) has decided to forbid use of antibiotics as growth promoters. Although many researches had been conducted about fiber source as alternatives of antibiotics, there are still lack of reports in the literature about the optimum level of sugar beet pulp supplementation, affecting growth performance and nutrient digestibility in weaning pigs. Therefore, di...
