A four-year study of site-specific weed control is presented in this paper. Weed seedling distribution was sampled and mapped prior to and after post-emergence herbicide application in four fields planted with maize, sugar beets, winter wheat and winter barley, rotating on one site. Herbicides and other weed control strategies were applied site-specifically according to the spatial variation of weed populations.

Eddy covariance measurements of CO2 fluxes were conducted in 2004 at the agricultural site of Lonzée, Belgium, over a sugar beet crop. Additional measurements of biomass net primary production and leaf area index (LAI) were carried out. The response of the fluxes to climatic and non-climatic variables was analysed. Nighttime fluxes were dependent on turbulence, temperature and high soil water

Sugar beet seeds are imported from European countries with expensive cost as well as many tries were procedured for flowering and seeds production but without any outcome, therefore that the use of tissue culture technique is a useful tool in Egypt. The investigation was carried out during 2017-2018 at the laboratories of the cell research department, field crops research institute, agricultural research center, An indirect regeneration protocol for micropropagation of some sugar beet (Beta vulgaris L.) genotypes and the genetic variation were described. For callus production, hypocotyl, cotyledon explants were cultured on Murashige and Skoog's medium supplemented with 0.1 mg/l BAP+2.0 mg/l 2,4-D and cotyledon explants produced significantly more calli than hypocotyl explants. Significant difference among the genotypes and among the different media was observed. For shoot induction callus of different explants was transferred to MS-medium containing 1.0 mg/l BAP+0.2 mg/l IAA. The regenerated shoots were transferred to rooting MS-medium containing 3.0 mg/l IBA+0.3 mg/l NAA. The genetic variation among the sugar beet genotypes was based on RAPD-PCR data suggest a relatively high genetic diversity among them, that can be used in the breeding programs taking into account select the parents, which have the wide genetic distance.

The antimicrobial activities of five commercial disinfectants containing quaternary ammonium compound-isopropanol (D1), sodium methyl dithiocarbamate (D2), sodium thiocarbamate (D3), sodium dimethyl dithiocarbamate (D4) and formaldehyde (D5) were studied against three main saccharolytic indigenous isolates (Bacillus cereus, Lactobacillus plantarum and Leuconostoc mesenteroides) from a beet sugar extraction line. Preliminary studies suggested that although all the disinfectants were effective against those isolates, the high economic cost in combination with large amounts of the disinfectants D2, D3 and D4 weaken their possibility for industrial use. Therefore, the minimum inhibitory concentration (MIC) of the other two examined disinfectants D1 and D5 was determined and survivor curves were obtained, for a period of 7 days. Bacterial counts against time (h) suggested that D1 was more effective than D5 against the microbial population. In particular, D1 was bacteriolytic above 7 mg/l for B. cereus and bactericidal above 80 mg/l for Lc. mesenteroides and above 100 mg/l for L. plantarum. The disinfectant D5 was bacteriolytic above 25 mg/l for B. cereus and bactericidal above 500 mg/l for Lc. mesenteroides and L. plantarum. Taking into consideration both features, i.e. high concentration and very low cost, the use of D5 (formaldehyde) appeared more suitable to the concerned beet sugar processor.

Priming of sugarbeet (Beta vulgaris L.) seeds induces increased solubilization of the basic B-subunit of 11-Sglobulin (a major seed storage protein in sugarbeet).Using a sensitive single-seed ELISA, the soluble andtotal B-subunit contents of individual untreated andprimed sugarbeet seeds were measured. With theuntreated seeds, there was a 160-fold range of thesoluble B-subunit content among individual seeds. Theindividual primed seeds also exhibited large variations intheir soluble B-subunit content, yet only over a five-foldrange. Furthermore, the frequency distributions ofsoluble B-subunit content were markedly different for theprimed and untreated seed populations; the primed seedpopulation exhibited a substantially higher median thanthat for the untreated seed population. In markedcontrast, and as expected from results with pooled seedsamples, the distributions of total B-subunit content weresuperimposed when comparing untreated and primed seed populations

A field experiment was conducted at the research farm of the Department of Agronomy, Bangabandhu Sheikh Mujibur Rahman Agricultural University, Gazipur, from November 2011 to May 2012 to find out the growth pattern and optimum sowing date of tropical sugar beet in Bangladesh. The tropical sugar beet genotypes were Cauvery, Shubhra and EB0616, and sowing dates were 01 November, 15 November, 01 December and 15 December. The interaction effect of sowing dates and sugar beet genotypes was statistically significant in growth
parameters like leave number, leaf area index (LAI), crop growth rate (CGR), root weight per plant, root yield. The highest root yield was obtained from genotypes EB0616 when sown on 01 November (103.5 t/ha) and 15 November (100 t/ha). The genotypes Cauvery and Shubhra gave identical root yield i.e., 90.27 t/ha and 92.86 t/ha, respectively on 01 November sowing. Root yield significantly decreased in all the three genotypes with the advancement of sowing dates from 01 November onwards. For high root yield the optimum sowing date for tropical sugar beet in Bangladesh seems to be in early November. Get more articles at: http://www.innspub.net/volume-7-number-1-july-2015-ijaar/

Emissions of greenhouse gases such as CO2, CO, CH4 and NOX from fossil fuel use are implicated in climate change. The use of bioethanol is one means to reduce fossil fuel use and emissions of greenhouse gases. This study investigated research to produce ethanol from sugar beet and use as fuel in Turkey. The calculated demand for bioethanol amounted to

Chenopodium album is a worldwide-distributed plant species growing in disturbed habitats. It is an abundant and very competitive weed in spring-sown crops, particularly if they retain an open structure for a relatively long period. In most crops it is currently controlled by herbicides. In some crops, such as maize, chemical control is difficult, because C. album has become resistant to

Se estudió de forma general el comportamiento del color en el proceso de producción del azúcar de plantación, los principales precursores de color y otros factores relacionados con la generación de color dentro del proceso de producción de azúcar blanco de sulfitado y azúcar crudo. Se observó la persistencia y variaciones de compuestos fenólicos y aminoácidos en toda la línea de proceso y su incursión a los cristales de azúcar, evidenciando mecanismos de generación de color por etapa de proceso; también se observó una relación directa entre el contenido de los precursores de color y el color del azúcar producido.

Una investigación bibliográfica y ensayos de laboratorios han sido realizados para determinar los principales factores que influencian el desarrollo del color durante el almacenamiento del azúcar, centrándose en el azúcar blanco sulfitado. Los resultados concernientes al color, el contenido de aminoácidos, azúcares reductores, flavonoides, sulfitos y temperatura han permitido describir en cierta medida el fenómeno del pardeamiento del azúcar durante el almacenamiento. Se ha observado que la tasa de transferencia de calor entre el interior de una estiba y el exterior es muy bajo, pudiéndose conservar la temperatura a la cual se almacena el azúcar durante un periodo prolongado. Así mismo se ha determinado que la temperatura de almacenamiento es clave para la cinética del pardeamiento del azúcar durante su almacenamiento.
