By employing sugar as a social metaphor, whether in narrative foreground or as backdrop, Caribbean writers confronted the oppressive histories and dark human institutions that arose together with the region’s sugar economy. This proto-metaphor of sugar appealed to the legacy of a generational psychology as much as it did to a contemporary public conscience over the social travail that the industry generated.

The word ‘diaspora’ etymologically pertains to Greek
language. Literally it is a compound of ‘dia’ means
‘across’ and ‘speiro’ means ‘scatter’. Therefore, the word
diaspora denotes the scattering of people en masse form
one place to other. It is the movement of the people being
away from their own country. There are various sorts of
diasporas in human history of the world. Almost every
country of the world has faced this movement of
population some way or other. Out of these some famous
diasporas are—Jewish Diaspora, African Diaspora,
Greek Diaspora, Italian Diaspora and Indian Diaspora.
There are various reasons behind the mass movement
of the people from one place to another. Some can be
counted as the result of colonialism, imperialism, and
quest of better livelihood. The leaving of the home
country was involuntarily or reluctantly and they had
desire to come back to their homeland. They had the
feeling of nostalgia and homesickness.

The objective of this work is to apply optimization techniques (OT) including Multi-Objective Genetic Algorithm (MOGA) and Data Envelopment Analysis (DEA) for environmental impact category reduction and energy use optimization in planted and ratoon farms of sugarcane production at Imam Khomeini Sugarcane Agro-Industrial Company (IKSAIC) in southern Iran. Results demonstrate that energy savings by applying MOGA and DEA in planted farms are 20.90% and 8.52%, respectively whilst the corresponding values in ratoon farms are 2.61% and 13.90%, respectively. The increase of energy use efficiency is mainly attributed to electricity, diesel fuel, human labor and nitrogen fertilizer in sugarcane production (planted and ratoon). Furthermore, most environmental impacts under MOGA condition are considerably lower than those under DEA, which are in turn less than the present conditions for both farms (planted and ratoon). The largest variations between MOGA and DEA are on terrestrial ecotoxicity and photochemical oxidation in planted farms and ratoon farms, respectively. MOGA is a feasible OT to assign the best input combinations for planted and ratoon sugarcane productions, by reducing environmental impacts and simultaneously enhancing farms productivity and energy use efficiency. Results are useful to authorities in making decision regarding sustainable expansion of sugarcane production in Iran.

Production is the combination of production factors in any sector of the economy in general there is a functional relationship between inputs and output. The agriculture production is depends on number of factors, such as land, labour, capital and organization etc. The ownership of the factors, market facilities, government policies are also influenced the production. India is basically agrarian economy; the crops in agriculture are broadly divided into food and commercial crops. Sugarcane is not only commercial crop, but also food orientated for the millions of people. The sugarcane production basically depends on various production factors and these are varied from one region to other and in different landholdings. The present study made an attempt on the cost of cultivation and the production function of different landholdings with the support of primary and secondary data. The primary data collected from the respondents in the sample village of Channaram in Nelakondapally mandal of Khammam district in Telangana. The secondary data has been collected through the statistical abstracts and the official reports journals and the publications. This study is having the some objectives, to find out the land holdings, to reveals the production practices in the cultivation of sugarcane and finally to examine the production function of the sugarcane crop. For this study the researcher has used the simple production functions, and the simple averages and percentages.

An experiment was conducted in Old Himalayan Piedmont Plain soils at Regional Sugarcane Research Station farm, Thakugaon during 2005-06 and 2006-07 cropping season with a view to find out the suitable time and methods of planting for sustainable sugarcane production and quality of cane in northern region of Bangladesh. There were two planting methods viz. transplanting of one budded soil bed settling and planting of three budded fresh setts with five different planting times at one month interval starting from 15th November. STP (one budded settlings) method produced higher yield than conventional method at all dates of planting. In case of STP, yield level and yield contributing factors were found to decrease as the planting time proceeded. Both conventional and STP method of planting produced the highest yield in November and the lowest yield in March plantation. Planting methods and time had no significant effects on the sucrose content of sugarcane.

The number of sugarcane processors in Louisiana has decreased over time forcing growers to begin the harvest
season earlier for fear of complete cane loss at the end of the harvest period due to freezing temperatures as
winter sets in. Experiments were conducted during 2004-2008 in Louisiana, USA to investigate effects of early
harvest on ratooning ability and to determine differential effects of early harvest among four cultivars grown
locally. Plant-cane cv. LCP 85-384, ho 95-988, hoCP 96-540, and L 97-128 were harvested on 1 October (early)
and 1 December (mid-season). Averaged across all cultivars, the October harvest of plant-cane reduced sucrose
yields (p = 0.01) of the first-ratoon (7.7 t/ha) compared to the mid-season harvest date (10.1 t/ha.). The sucrose
yields for L 97-128 were 0.6, 3.0, and 3.9 t/ha greater (p = 0.01) than hoCP 96-540, LCP 85-384, and ho 95-988,
respectively, for the early harvest. A second experiment was initiated to determine the effects of two consecutive
years of early harvest (plant-cane and first-ratoon) on yields of the second-ratoon. Averaged across all cultivars,
the October harvest of both plant-cane and first-ratoon reduced sugar yields (p = 0.01) of the subsequent
second-ratoon (5.5 t/ha) compared to the December harvest (10.0 t/ha). For the October harvest, LCP 85-384,
hoCP 96-540, and L 97-128 had significantly higher sugar yields (6.1, 5.6, and 6.6 t/ha), respectively, relative to
ho 95-988 (3.6 t/ha). Both harvest dates for L 97-128 produced equivalent yields, indicating that this cultivar is
best suited for early harvest. All cultivars had decreased yields with consecutive October harvests. It is currently
suggested that growers should not harvest cane early in consecutive seasons because yields are reduced below
the point of a positive return on input costs.

Sugar cane (Saccharum officinarum L.), the tall perennial grass from the family member of the grass family Gramineae, is the major sugar crop from which sugar is produced. Its bye-products have found use in industrial settings of medicine, pharmaceuticals, confectionery and beverages, electricity and motor fuels. The production of this wonderful crop in Nigeria and some Northern African countries is besieged with a number of problems ranging from biotic and abiotic to social and environmental. In spite of these, efforts have continued to be made by sugar cane growers and the governments of these nations with little or no tangible results in Nigeria and with excellent results in Northern African countries in terms of total hectares put to sugar cane production and availability of certification schemes to check excessive and uncontrolled expansion as well as the yield per hectare of millable cane and sugar yield. Common problems militating against increased sugar cane production in Nigeria and Northern African countries like requirement capital, lack of market outlay, biotic and abiotic stresses, high transport and production costs of hauling harvested sugar cane to the mills, low capacity building, lack of sugar cane growers and technologist associations, macro-and micro-environmental issues, lack of legal frameworks and lack of national and regional networking groups are highlighted in this paper. A general lack of political will to enforce stiff legislations on sugar imports is also discussed. Stakeholders in the sugar cane industry in these countries are called upon to initiate proactive measures that will surmount these problems in order to step up sugar cane production.

The objective of this work is to apply optimization techniques (OT) including Multi-Objective Genetic Algorithm (MOGA) and Data Envelopment Analysis (DEA) for environmental impact category reduction and energy use optimization in planted and ratoon farms of sugarcane production at Imam Khomeini Sugarcane Agro-Industrial Company (IKSAIC) in southern Iran. Results demonstrate that energy savings by applying MOGA and DEA in planted farms are 20.90% and 8.52%, respectively whilst the corresponding values in ratoon farms are 2.61% and 13.90%, respectively. The increase of energy use efficiency is mainly attributed to electricity, diesel fuel, human labor and nitrogen fertilizer in sugarcane production (planted and ratoon). Furthermore, most environmental impacts under MOGA condition are considerably lower than those under DEA, which are in turn less than the present conditions for both farms (planted and ratoon). The largest variations between MOGA and DEA are on terrestrial ecotoxicity and photochemical oxidation in planted farms and ratoon farms, respectively. MOGA is a feasible OT to assign the best input combinations for planted and ratoon sugarcane productions, by reducing environmental impacts and simultaneously enhancing farms productivity and energy use efficiency. Results are useful to authorities in making decision regarding sustainable expansion of sugarcane production in Iran.

Sugarcane is an important commercial crop among the different commercial crops in India. It is the agro and industrial based crop, like jute and cotton. Through the cultivation of sugarcane more than 40 million farmers are depending by the growing of this crop. At the same time more than 35 million of work force engaged in different cultivation activities in the production activities of sugarcane, and about 5.5 lakhs skilled and un-skilled workmen are directly employed in the sugar factories in addition to in informal sector of cottage industries which have run by the sugarcane and its by products the significant level of people are directly employed in Jaggary, Khandsari and the other by products. On the other hand the sugar industry contributes the more than 1000 crores to the central excise duty and taxes per year, it is similar to the state government provided by the different sugar factories are paying the taxes in different forms. All together the entire output value of the sugarcane and the sugar factories is more than 20000 crores per annum in Indian economy. In this context the present paper shall be focused the area, production, productivity of sugarcane recovery rate, at national. The main objective of this paper is to find out the area under the cultivation of sugarcane during the pre and post LPG periods. To find out the Production of sugarcane, to examine yield, along with the growth rate of sugar factories at national level. This study shall be use the secondary data only. In the description of the data the researcher uses the simple percentages and averages. Even though the study has its own limitation, the secondary data gathered by different source mostly CACP, FAO ISMA and SISMA etc. Some of the findings have been given here as brief manner. It can be observed the area and the yield of sugarcane are in the positive direction from 1950-51 to 2014 – 15, during the 65 years of planning both have increases 66.8 and 42.0 percent of area and yield. During the LPG period of 25 years both are in the same direction i.e., 28.34 percent in area and 6.39 percent in average yield. In 1950 to 1990 the area and average production of sugarcane have been observes as significantly in progressive way, i.e., 53.69 and 38.0 percent respectively. The growth rate of area and average yield are low after the globalization era.

The relationship between sugarcane genotype and symbiosis with arbuscular mycorrhizal fungi (AMF) remains poorly understood, especially regarding different soil moisture levels. Our objective was to evaluate the effect of soil moisture on the AMF community structure, spore abundance and colonization ratio in a plantation with eight sugarcane genotypes (CTC15, CTC17, RB867515, RB92579, RB931011, RB966928, IAC5000 and NCo376). The study was carried out in Piracicaba, Sa˜o Paulo and Brazil in an experimental plot setup in a randomized block design, with three replicates (blocks). We collected soil and root samples in a greenhouse experiment under two water replenishment levels: 100 and 50% of soil moisture at field capacity (hFC). We extracted spores and assessed the AMF root colonization ratio by using specific dyes and determining the percentage of root length colonized in the different sugarcane genotypes. In addition, we evaluated the AMF community structure by PCR and denaturing gradient gel electrophoresis. In general, the spore abundance and root colonization ratio were higher in all varieties at 100% hFC. However, the IAC5000 and RB966928 genotypes showed higher colonization levels even at 50% hFC. The AMF community structure was also influenced by soil water levels with group separations across 100 and 50% hFC. Sugarcane productivity as measured by stalk plus root dry mass was positively correlated with AMF colonization rates in 100% hFC. Thus, the water replenishment levels used in sugarcane cultivation can influence spore abundance, colonization ratios and AMF community structure in the soil. The selection of a sugarcane genotype with greater AMF association under low water replenishment levels may be a primary factor in growing sugarcane in areas with low water availability.

Current paper summarises the results of typo-chronological, petrographical and chemical studies of the ceramic vessels associated with sugar production (sugar molds and molasses jars) from the archaeological sites excavated and surveyed within the 'Akko Plain. The sites, dated between 11 th and 17 th centuries, provide wide repertoire of the vessels which covers the whole timescale from Fatimid, Frankish to Ottoman rules. The provided research sheds a light on the dynamics of the sugar molds modification. During the Frankish rule, when the government was settled in 'Akko, the manufacturing centres were concentrated in the coastal area, and the molds were mass-produced, probably with the active participation of the government. In later times, Mamluk and Ottoman, the sugar molds manufacture was moved inland, which correlates with the movement of the seat of government to Safed.

The cultivation of sugarcane represents an important part in the Colombian economy due to the diverse applications in industries like liquor, food, paper and biofuels. Sugarcane worldwide production is affected by the presence of phytopathogenic agents, mainly filamentous fungi such as Physalospora tucumanensis (red rot disease) and Fusarium spp. To date in Colombia, Pokka boheng disease whose causal agent is the fungus Fusarium verticillioides, has not been reported, which is why it is necessary to identify appropriately this microorganism, responsible for losses in productivity and food contamination. In order to isolate and identify the infectious agent from symptomatic tissues, disinfection and culture in liquid and solid culture mediums were performed in malt extract (2%) and yeast extract (0.2%) both liquid and solid, for 7 days. After several replicates in agar plate, a purification was made along with a morphological characterization based on the shape and color of the mycel...

This study introduced, for the first time worldwide, molasses as an additive in papermaking. The introduction of molasses as an additive in papermaking resulted in paper composites with greater breaking length and remarkably higher water retention value (WRV), compared with paper that does not have molasses as an additive. Previous studies have shown that incorporating the cell wall microstructure of cellulose fibers with sucrose greatly enhanced the breaking length and WRV. It is well established in the literature that using gums (including starch) as additives in papermaking enhances paper strength. Molasses, which contains sucrose and gums (including starch) is a byproduct of the sugar industry and is cheaper than sucrose. Mercerization of pulp fibers before loading them with molasses was shown to greatly enhance the positive effects produced by loading with molasses. Application: Paper composites produced using molasses as an additive are useful as specialty absorbent paper.

The need to optimize land use has never been greater than at present, when rapid population growth and urban expansion are making areas available for agriculture a relatively scarce commodity.Locating specific sugarcane areas in Negros Island and their specific constraints are paramount to properly manage the current and future use of these arable lands. Thus, this research was designed to determine sugarcane production related constraints of selected soils in Negros Island and to recommend management strategies to address these constraints.Suitability analysis was done following the FAO suitability analysis scheme. Results of suitability analysis served as basis in identifying constraints of a particular soil type when used for sugarcane production. Results revealed that all the 19 soil types used for sugarcane production in Negros Occidental were classified as marginally suitable according to the FAO scheme because of the existence of one severe limitation. The most common constraint found in sugarcane soils of Negros Occidental was wetness which depicts the possibility of flooding and drainage problem.Of the 10 soil types used for sugarcane production in Negros Oriental, only Siaton sandy loam was rated as moderately suitable because of the presence of only 2 slight limitations (wetness and climate) and 2 moderate limitations (soil fertility and physical properties). The remaining soil types were classified as marginally suitable with wetness and climate as the most dominating limitations.Furthermore, suitability map and constraint map were generated from the results of suitability analysis using FAO scheme. Recommended management strategies for each soil type were likewise suggested.

El cultivo de la caña de azúcar representa una parte importante en la economía de Colombia debido a las diversas aplicaciones en industrias como licor, alimentos, papel y biocombustibles. Su producción en todo el mundo se ve afectada por la presencia de agentes fitopatógenos, principalmente hongos filamentosos como Physalospora tucumanensis (agente causal de la enfermedad “Pudrición roja”) y Fusarium spp. Hasta la fecha, en Colombia, no se ha reportado la enfermedad de Pokka boheng en este cultivo cuyo agente causal es el hongo Fusarium verticillioides, por lo que es necesario identificar adecuadamente este microorganismo, responsable de las pérdidas en productividad y contaminación de los alimentos. Con el fin de aislar e identificar el agente infeccioso de los tejidos sintomáticos, se realizó la desinfección y posterior siembra de éstos en medios de cultivo extracto de malta (2 %) y extracto de levadura (0.2 %) tanto líquido como sólido durante 7 días. A partir de varias placas petri, se realizó la respectiva purificación y una caracterización morfológica basada en la forma y el color del micelio, así como el tipo de esporas generadas. Adicionalmente, el material genético se extrajo y se amplificaron los marcadores genéticos (ITS, factor de elongación 1-α (EF) y β-tubulina (Btub)) por PCR. Luego, se utilizó la secuenciación del ADN para obtener los datos para realizar una reconstrucción filogenética mediante métodos probabilísticos (máxima verosimilitud e inferencia bayesiana). La cepa aislada, nombrada como EA-FP0013 se localizó en el grupo del complejo Fujikuroi, con una alta identidad probable para Fusarium verticillioides. Por lo tanto, la identificación temprana y específica de especie de estos aislados fúngicos, utilizando métodos moleculares, puede permitir el diagnóstico oportuno de enfermedades fisiopatológicas emergentes de interés para la región, y así proponer las estrategias de control respectivas.

Purpose Field experiment was conducted to investigate the effect of enriched pressmud compost prepared from sugarcane industries byproducts on soil nutrient availability , growth, yield parameters and yield of rice. Method The effect of five levels of pressmud compost, viz., 0.00, 1.25, 2.50, 3.75 and 5.00 t ha-1 in two varieties, viz., ADT 36 and ADT 43 and a hybrid ADTRH 1 during the Kharif season of 2009 was studied. The experiment was conducted in a factorial randomized block design with three replications. Results The results of the field experiment revealed that the hybrid ADTRH 1 manifested higher grain and straw yield, whereas the variety ADT 43 and ADT 36 registered lower grain and straw yields, respectively. With regard to the enriched pressmud compost, the application of 1.25 t ha-1 of enriched pressmud compost recorded higher straw and grain yields and it was comparable with 2.50 t ha-1 of enriched pressmud compost. Nutrient availability, growth, yield and efficiency parameters of rice were comparable with application of 1.25 and 2.50 t ha-1 of enriched pressmud compost. Conclusion Considering the input cost, incorporation of 1.25 t ha-1 enriched pressmud compost as basal along with required remaining nitrogen through inorganic fertilizer as top dressing in three splits may be recommended for rice crop to realize maximum yield in kuruvai (kharif) season.

While the Yucatán Peninsula of Mexico may conjure up images of vacation getaways and cocktails by the sea, these easy stereotypes hide a story filled with sweat and toil. Few know the bittersweet story of sugar and rum in the jungles of the Yucatán Peninsula during the nineteenth century. This is much more than a history of coveted commodities. The unique story that unfolds is told through the lens of Maya laborers who worked under brutal conditions on small haciendas to harvest sugarcane and produce rum. Sugarcane and Rum brings this history to the present and explains how rum continues to impact the Yucatán and the people have lived there for millennia.

Tumbu sugar abstraction is an agriculture-based industrial products, conducted traditionally every cane harvest season. The result is formed in a tumbu, thus. it is called Tumbu sugar. The shape and size of brown sugar or sugar cane, both made from coconut sap, are considered less meet the demand of consumers who want practicality and convenience. Issues to be resolved in this research are improving quality, size and packaging to penetrate export markets. Sugar Tumbu currently form large chunks (100-125 kg), impractical to distribute, and not durable to be saved, easy to melt because it is hygroscopic. The purpose of this research is to produce or design a machine to generate sugar granules tapered cylindrical shape, diameter of 18 mm x height 16 mm = (18 x16) mm. The result of every production process is 10 x 10 = 100 grains. The method of generating mold unit of sugar granules comprising the steps: (1) determine the size of the products of sugar granules to be shaped, (2) designing and generating production machine according to the capacity of production, (3) designing the molding unit in accordance with the size of the shape of sugar granules, (4) test, repair and modification to obtain a good sugar granules. In initial test 10% of grains being produced are failed. It is solved by improving operator skill. On vacuum packaging test, Sugar granules were observed after 60 days seen no deformation compared with the unpackaged ones that become soft, and shrink. Sugar cane Products that molded into sugar granules and vacuum packed have the potential to become export products.
