rhizomania is one of the most important sugar beet diseases in iran and some other parts of the world. in this study, the infection rate of the most important weeds of sugar beet fields under natural condition  to the causal agent of the bnyvv (beet necrotic yellow vein virus) disease  was investigated at fars agricultural research center , iran. roots were collected from the infected weeds and...

many fungi cause sugar beet root rot during various stages of the plant growth. among them rhizoctonia spp. induce crown rot, dry rot and violet root rot on sugar beet (whitney and duffos,1986). root rot caused by phytophthora drechsleri has been observed in fields with excessive moisture (habibi,1975). pythium aphanidermatum has been recognized as one of the causal agents of sugar beet, dampin...

The article discusses the issues of increasing effectiveness functioning beet and raw sugar subcomplexes in terms environmental protection. main areas scientific technical progress aimed at profitability production beets, cane as a final product these well reducing harmful effects their growing andproduction processeson atmosphere, soil, water bodies have been identified. authors consider devel...

in order to study the reason for the prominent increase of the average of sugar content in sugar beet produced in iran in 2007 and finding the relation of this increase with climatic parameters, chenaran sugar factory district was chosen. due to precise and reliable statistical data of sugar factory during the campaign and weather data, chenaran sugar factory was chosen for this investigation. ...

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...

introduction sugar beet (beta vulgaris l.) as the second most important world’s sugar source after sugarcane is one of the major industrial crops. the presence of weeds in sugar beet fields, especially at early growth stages, results in a substantial decrease in the crop yield. it is very important to efficiently eliminate weeds at early growing stages. the first step of precision weed control ...

urea is the most common form of nitrogen fertilizer used in sugar beet cultivation. urea has a high solubility and its losses are high and consequently its efficiency is low. it is supposed that urea solubility can be limited and its efficiency can be increased by using slow-release nitrogen fertilizers. by conducting an experiment in three important sugar beet cultivation areas of khorasan pro...

the main objective of this research was the measurement of soil characteristics, land evaluation and determination of potential yield of sugar beet in yekanat plain of marand. for doing this, firstly, yield potential of sugar beet was estimated by fao method and secondly land evaluation of different soil units for sugar beet cultivation was determined by parametric method. results showed that m...
