Abstract

Tow field experiments were carried out to investigate the effect of three levels of row distance as well as cutting size on Juice quality attributes "TSS, Brix, sucrose, reducing sugars, purity, sugar recovery and fiber percentages" of three promising sugar cane varieties. The effects of row spacing and cutting size on all studied Juice quality attributes were not great enough to reach the significant level with the exception of the effect of row distance on fiber % in which the wider the row distance the higher the fiber % and vice versa. Varietal response to the studied factors varied greatly in respect to Juice quality parameters. Variety G. 85- 37 showed superiority in the TSS and inferiority in both purity and sugar recovery percentages when compared with the other two varieties. Meanwhile, variety F. 153 recorded the highest values of fiber and Brix % compared to the other two varieties. The commercial variety ( G. T. 54 - 9 ) showed superiority over the other two varieties in purity percentage. The first and second orders interactions effect on sugar recovery were significant.
