Sucrose losses after cane harvest is one of the most important problems in sugarcane crop particularly for millers and farmers. Loss in sucrose after harvesting causes low sugar recovery in mills. There are a large number of factors associated with low sugar recovery such as varietal type, atmospheric conditions, time lag, etc. Sucrose losses occurring in postharvest sugarcane are generally of ...

In a field trial conducted with eight varieties in the north coast area of Natal ratoon stunting disease (RSD) caused increasing lossesin yieldsof cane and sucrosefrom the plant to the second ratoon crop. All the varieties suffered losses in yield but the degree of loss differed markedly among the varieties. The total yield of sugar from the three crops was reduced by 38% in varieties NCo 376an...

mills are able to accept chopped cane. In the past three years several locally developed whole stalk harvesters and imported chopper harvesters have come into use in many areas of the South African sugar industry. The Experiment Station therefore conducted time and motion studies during the past two seasons to assess the performance of these harvesters while operating under local field and crop...

Sugar-cane stalks, 2.0 cm long, were used as a support for yeast immobilization envisaging ethanol production. The assays were conducted in 38.5 L fermenters containing a bed of stalks with 50% porosity. The operational stability of the immobilized yeast, the efficiency and stability of the process, as well as the best dilution rate were evaluated. Molasses from demerara sugar production was us...

A variant ofSCMV-D is the most common strain of sugarcane mosaic virus (SCMV) occurring in sugarcane in the coastal hinterland and high altitude areas of Natal. In field trials conducted at Mount Edgecombe and Eston this strain decreased the yield of recoverable sugar from variety NCo 376 by 30 to 42 % and that from variety Nl2 by 15 to 30% when all the stalks were infected. Losses in yield wer...

abstract soil compaction is a main factor that reduces the cane yield in sugarcane fields, in southwest of iran, especially in ratoon cropping system. therefore, sub-soiling practices could alleviate adverse effects of compaction and increased yield. in according to this aim, a study was to evaluate the effect of  ratooning practice systems consisting of control (no subsoiler), two and four sha...

Information was sought on the cause, effects, and control of dextran in sugar manufacture in Jamaica. Storage experiments on manually harvested, burnt, whole-stalk cane revealed that Leuconostoc mesenteroides was the predominant spoilage organism. Its growth was accompanied by significant increases in dextran content and juice viscosity. However, these parameters. did not increase linearly with...

The results of two field trials to determine the effect of ratoon stunting disease on the growth and yield of some widely grown and newly released sugarcane varieties are described. In the plant crop of a trial grown under full irrigation, the greatest reductions in yields of cane and sugar among six varieties, approximately 15%, occurred in N 14 and NC0376. In the first ratoon, the greatest re...

Sweet, grain, and dual-purpose sorghums differ in a number of important traits, including biomass production, total solutes the stem juice, sugar accumulation across stem. Ten hybrids, two sweet genotypes, grain landraces were characterized under temperate environmental conditions to determine their potential for bioethanol production. Five sorghum hybrids (Ganymed, Hannibal, Tarzan, Merlin, Ze...
