Effect of Harvesting Age on Yield of Exotic Sugarcane Varieties at Metahara Sugar Estate

Yohannes Mequanent, Netsanet Ayele

Abstract


Viability of a given sugar sector depends on the yield of sugar and age of harvesting affects sugar yield the return the most. Therefore, an experiment was conducted at Metahara Sugar Estate plantation to determine the effect of different harvesting ages (12,14 and 16 months after planting) on 12 sugarcane varieties (C86-12, C90-501, C86-165, C132-81, C120-78, C1051-73, B78-505, B80-250, SP70-1284, C86-56, NCo334 and B52-334) on plant cane crop using a factorial RCBD design with three replications. Analysis of variance indicated that none of the interactions were found to be significant; however, the main effects age of harvesting and variety were significant (p<0.01). Harvesting cane at the age of 14 months gave a significantly (p<0.01) higher sucrose percent cane than 12 and 16 months of age harvesting which were in statistical parity. However, 14 and 16 months of age harvesting were not significantly differed each other; however, they were superior to 12 months of age harvesting. Therefore, it can be concluded that the harvesting age should range from 14 to 16 months for maximum economic advantage for the varieties considered.
