Two growth trials are reported. In the first (of 141 days) , 42 bulls of initially about 220 kg and 2 years of age were given: (A) chopped whole sugar cane ad libitum plus 300 g/d extracted soya bean meal; (B), © and (D) as (A), but with 100, 200 or 300 g molasses/urea (2.5%) per kg fresh cape mixed into the cane; (E) as (D) , but with 600 g soya/d; (F) , chopped whole cane plus 1 kg/d wheat br...

As a result of deterioration in the colour and polarisation of the VHP sugar caused by abnormal cane quality during October of the 1983/84 crushing season, it was decided to test a modified boiling system at Illovo as proposed by van Hengel at the SASTA Congress of 1983. The results achieved for the period before, during and after the trial are presented and compared. It was found that the qual...

Saccharococcus sacchari is the primary colonizer of the developing "sterile" tissue between the leaf sheath and stem of sugar cane. The honeydew secreted by the mealybugs is acidic (about pH 3) and supports an atypical epiphytic microbiota dominated by acetobacter-like bacteria and acidophilic yeast species. However, Erwinia and Leuconostoc species predominate within the leaf sheath pocket regi...

The text area is 29 × 45 picas (~12.3 cm × 19 cm) to fit in the printed proceedings book without reduction. When printed on letter paper there will be wide margins. Abstract. Previous use of Artificial Intelligence (AI) in agriculture for forecasting productivity indicators, especially Artificial Neural Networks (ANN), has shown that it is possible to approximate sugarcane maturation curves. Ho...

Althougll starch poses a problem in the factory by retarding filtration and crystallization rates of cane juices (Balch, 1953; Feulherade, ~gzg) , little attention has been given the mechanisms of starch formation in sugarcane. Of further importance is the knowledge that both glucose-I-phosphate* and uridine diphospl~oglucose, themselves major precursors of sucrose, are also involved in starch ...

-This IS a subject which does not at first sight appear to be of major importance in Cane Sugar Factory operation nor possibly of sufficient interest to warrant intensive thought on the part of the Engineer whose duty it is to keep machinery run"ning at all costs. Lubrication is only too often regarded as a necessary evil-a messy, troublesome -subject only to be tackled as and when hitches occu...

Sugar cane is one of the most successful tropical crops, with many agronomic factors in its favour such as high yield, tolerance of a wide range of soils, resistance-to pests, a perennial growth habit, and a sophisticated supportive technology providing improved varieties and cultural practices. It is still grown almost exclusively for sugar production; however, a number of alternative uses hav...
