While weeds in sugar beet farming reduce crop yield and quality, they also lead to higher labor and material losses. In recent years, in order to eliminate or reduce the damage caused by weeds in sugar beet farming, weed control has gained importance. To this end, various studies have been conducted on robotic weed control by detecting weeds using image processing algorithms and hoeing or spray...

in this research, 30 sugar beet breeding populations developed by crossing of sugar beet monogerm and multigerm male strile lines with nematode resistant wild sources (w-1009 contaning resistance gene from beta procumbens and w-1010 contaning resistance genes from beta maritima) were compared with resistant and susceptible checks with respect to nematode resistance and yield. the experiments we...

sugar  is very important role  in  humanbeing feed.  for sugar beet  production in tropical area detemine  sowing and  harvesting date is very important . for this reason three sowing date (1 sep, 20 sep and 10 oct) and three harvesting date (15 apr, 15 may and 15 jun) in complete blouck design as factorial with three replication in two year in sarpol area condoucted. results  showed  that  the...

models can be used to predict crop yield and inputs levels such as fertilizer, in order to conduct programming for the management of probable future crisis. in this study, based on the model, the effect of nitrogen fertilizer on dry matter partitioning in shoot and root of sugar beet was predicted. for model construction, data were collected from an experiment conducted in karaj city in 2001. i...

powdery mildew disease caused quality and quantity losses of sugar beet production. therefore, five spraying treatments and three sugar beet variety were conducted in split plot design with four reapplications during consecutive two years in kermanshah and mashhad regions. in order to control of disease, tridimorph fungicide was used. spraying treatments were in main plot and variety in the sub...

The reducing sugar content of sugar beet (Beta vulgaris L.) roots increased during 30 days of storage at 21 C and 160 days at 5 C as a result of an increase in acid invertase activity. Sucrose synthetase and neutral invertase activities were high at harvest but declined during storage, thus showing no relationship with postharvest reducing sugar accumulation in sugar beet roots. Acid alpha-gluc...

We analyzed a metagenome of the bacterial community associated with the taproot of sugar beet (Beta vulgaris L.) in order to investigate the genes involved in plant growth-promoting traits (PGPTs), namely 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase, indole acetic acid (IAA), N2 fixation, phosphate solubilization, pyrroloquinoline quinone, siderophores, and plant disease suppression as...

the study was conducted during 2002- 2007 in the first and last stage of a four-year rotation (sugar beet, forage maize, onion, wheat and sugar beet) at research station of irrigation and drainage rudasht. in each year, four treatments of organic fertilizers (25 and 50 t/ha urban compost and 15 and 30 t/ha sewage sludge) with a control (no organic fertilizer) were studied in a randomized comple...

in order to improve the efficiency of irrigation systems and investigate their impact on the pest population levels, furrow and sprinkler irrigation systems were compared in sugar beet fields. in this study, three different fields were chosen and irrigated by one of the furrow, classic and center pivot irrigation systems.  in each field, 20 plots were randomly selected of which 10 plots were ma...

background and objectives: sugar beet seed plants about five to six weeks after the formation of a seed stem, flowering started and within two weeks, this stage of plant growth will be completed. a significant negative correlation between the temperature received from flowering to seed maturity and the plant reproductive growth period with grain yield shows that the long plant reproductive grow...
